Stanced out to make all the pussies wet

(http://i.imgur.com/776DEft.jpg)
seat in for a test fit and to sit in it and make racecar noises. I gutted the car awhile ago. The stock interior was fucked from the battery tray being rusted and water leaking into the passenger side. All the carpet was rotted, seated rotted, seat brackets rusted etc.

(http://i.imgur.com/8MNYvt7.jpg)
mostly stripped down original motor.  Previous owner didnt do the 30k timing belt, smashed all the valves.

Stinky ass LM4 aluminum 5.3 in the back of my xterra.

Figuring out this pos mig fixing the battery tray rust. Seam sealed the entire thing then rhino-lined it. Hopefully it never rusts again.

Using the corvette c5 slave with remote bleeder and lines that cost too fucking much.

(http://i.imgur.com/56tlP3q.jpg)
Corvette c5 bellhousing, torque tube to bellhousing adapter, misc bullshit.

(http://i.imgur.com/Htnb2WD.jpg)
Spec clutch, JD said it was shit and I should get a mcleod twin disc.

(http://i.imgur.com/04hZ1By.jpg)
so I did.

(http://i.imgur.com/bddsNvw.jpg)
purp fuel rails so i can blaze it.

(http://i.imgur.com/uLY5B8c.jpg)

Fuel pump installed so I can wheelie.

(http://i.imgur.com/7ytnC4d.jpg)
using the wix filter/regulator combo from a c5 vette and running -6 from the tank to the rail

(http://i.imgur.com/z05lCVx.jpg)
old motor out with no lift pure brute strength lol.


(http://i.imgur.com/WcN3PT8.jpg)

bay cleaned up further once i could get in there to do work.

(http://i.imgur.com/CHXfKzV.jpg)
using cave man tactics to put the engine on the stand. Still no lift at this time.

All observers thought i was going to die.

(http://i.imgur.com/8fDrP3e.jpg)
Put the pan on the engine so I could find where the pan needed to be cut to clear the cross member.

(http://i.imgur.com/GzmPJtA.jpg)
cut pan finished.


(http://i.imgur.com/4RQ6ZxE.jpg)

cleaned the valve covers to paint them black so that they may never go back.

(http://i.imgur.com/7VrfyW4.jpg)

#blacked. Didn't come out that well.

(http://i.imgur.com/trORoz2.jpg)
ls1 intake, chinese fuel rails, custom accessory bracket that im not sure if I like or not. I should have just bought the fbody shit for the lower mounting points.

(http://i.imgur.com/dsEIwH4.jpg)
the harness. I had to convert from DBW to DBC and remove a bunch of shit.

(http://i.imgur.com/R9AwfDd.jpg)
(http://i.imgur.com/mD334Qg.jpg)
harness finished and labeled.

(http://i.imgur.com/lfnSNmS.jpg)
stock brake booster does not fit with the swap.

The options are manual brakes, electronic booster or hydro boost.

This is a hydroboost unit from a mustang cobra.  hissssssssssssssss


(http://i.imgur.com/oeBkZ8A.jpg)

Hydroboost bracket finished and hydroboost mounted.

(http://i.imgur.com/kZMjBeP.jpg)
Car back on the ground for the first time in years.

(http://i.imgur.com/IWVBoYX.jpg)
Initial test fit of the engine.

(http://i.imgur.com/uiOcNNN.jpg)
Motor sitting in the car for the first time bolted down.

(http://i.imgur.com/hUBJ9ST.jpg)

Coil packs hit the hydroboost so the last pack needed to be moved up an inch.

(http://i.imgur.com/QIPwJ05.jpg)
that ebay throttle body hit the hood so I had to go with an ls1 unit.
Harness looks great in this picture I'm sure everything will go fine.

(http://i.imgur.com/Bb2DUM9.jpg)
lalalalalalala installing injector clips

(http://i.imgur.com/qpuFNGy.jpg)
relooming.

(http://i.imgur.com/UxKO4km.jpg)
Shiny fucking headers because mine were an inch too wide on the passenger side.

(http://i.imgur.com/INNisye.jpg)
car almost ready to be started. Still need to do something about the filter and the maf. There's not a lot of room up front and my power steering mount fucks me. Would have been fine with the fbody shit but I dont want to spend that much on brackets and an fbody pully.

I skipped building the power steering lines I guess.

(http://i.imgur.com/mP00zP8.jpg)

remote mount oil filter bracket made and buggered on.

Caught the horns on a little bit of fire during this.


(http://i.imgur.com/IRb6D58.jpg)
Y pipe built that I still need to unfuck. I angled it down a little too much and one of the 02 sensors is at a poor angle because of it.


https://scontent.cdninstagram.com/t50.2886-16/15675327_1760086374310191_2376729528878759936_n.mp4 (https://scontent.cdninstagram.com/t50.2886-16/15675327_1760086374310191_2376729528878759936_n.mp4)

The second start of the car.

All the smoke is the oil burning off from fogging the cylinders down.

That's about where I'm at. Next steps are brakes, get the clutch working (bad master), and get it to a cage shop.

There's a lot of pictures and shit I'm leaving out because I'm too lazy to connect to my phone so this is all instagram shit.

Let the shit talk commence.

Where's the turbo go?

Maybe in the next iteration. I can hit the max power a turbo trans can take N/A (~500hp) with a medium build and I want to drive it for awhile before I go full assed and drop a c5 transaxle in it.  If I do any go fast parts im doing heads and cam next.

The parts are sitting at my house I just haven't had time or the weather has been shit.

I'm trying to find someone to cage it. I got quoted 3500 for a fucking 6 point or 1500 for a roll bar.

It was nice out today so I got some work done. Finished the brake lines and installed a prop valve. My lines look like shit but hopefully nothing leaks. Replaced the clutch master and bled the clutch lines so now that works finally.  Getting closer to burnouts and rippers.

Started rebuilding the calipers. The hardware is fucked up on the driver side caliper so I'm going to need to order some.  Probably wont have anymore progress for a little while since I'm back on the road working.

Hopefully we will have another WNC meet so I can see this thing.

I'm probably going to take a trip down there regardless so if we don't have a meet you can still stop by and spew some ribs lol

I bought some new hoses and I'm changing this up tomorrow. I'll probably still have to use some metal, though.

(https://scontent.cdninstagram.com/t51.2885-15/s640x640/sh0.08/e35/16789826_1485184804848747_5624664985880756224_n.jpg)

Seats mounted, need to buy another one. I wasn't going to go with this seat but after having it in the car, I like it a lot.

(https://scontent.cdninstagram.com/t51.2885-15/s640x640/sh0.08/e35/16465157_265957587150903_7678362585543999488_n.jpg)

I was going to pay someone to cage it. The roommate has a pipe bender but the radius is huge. Made a test bend and for the main hoop, that radius is going to work extremely well so tomorrow if I can hit up airgas and alro, I should be able to get the rollbar done. I'm using a schroth DOT approved 3 point harness that hopefully isnt too annoying in a street car.

Still no ETA on burnouts

Main hoop took two tries because I used the wrong reference on the bender and added an inch on each side to the first try

I've got plenty of head room but the seat is tall as fuck I might try to drop it some more but that's going to involve cutting the floor pan out. The front has about 1.5 inches it can drop on the brackets but the rear is at the bottom.

Still no where near it being driveable. Brakes need done, exhaust,  power steering return, fixing some wiring that I angle grinded, hood pins installed, tires, maybe wheel bearings, dash and door cards refinished. Feels like a ton of shit to do.

The welds are good and gas welds but the welder is a bag of dicks and has no heat control other than high and low so I have to compensate with speed so my welds look like assholes on thin material.  Next big tool investment is a miller mig.

Exhaust is done and I've got some other issues to work through at the moment.

PS rack is leaking for some reason turning the fluid into a strawberry milkshake. Car wont idle correctly with the MAF plugged in and I dont think the tps signal is correct either causing the motor to behave weirdly to throttle input.

Rear brakes still not done yet because I need the PS hydraulics working correctly for the brakes anyway.

Did some interior stuff. Bought the amp and speakers im using for a stereo. 4 channel blue tooth amp and 4 4x6 kickers.

I haven't done much lately. Just started a new job so I'll have more time to dick with it.

It's running like shit and I havent put in much work to figure out why. I think the bank2 o2 is dicked because I bought ebay sensors. It runs so rich and smells of carbon monoxide poisoning garage based suicide when it hits closed loop and starts to stumble and shit.

Time for a turbo :P

I don't think I could come up with a drivetrain that could handle one or I'd try. The only good option for that is a full Corvette swap.

If I get it running right I'll cam it and throw some heads on and call it a day.


I'm pretty sure the o2s are swapped causing the fuel trims to freak out

I bypassed the power steering rack and I'm just going to fill it up with grease and cap it. Trying to fix it is futile. Hydroboost works now and the ps fluid stopped turning into a milkshake. I'm not sure I like how the hydroboost feels, though.



The gauge situation is annoying. The speedo cable goes through an inconvenient passage and isn't going to work even with good heat shielding so I bought a marine GPS unit that has a pulse signal out for speed for 38 bucks on eBay.


I couldn't get the factory tach to work with the LS ecu tachometer output even with a pull up resistor. I think that tach might be fucked. Who knows how long its been sitting.

The goal right now is to just use my old arduino and a few digital displays for speed / tach / watertemp and use a neopixel array for the tach/shiftlight.


Found out a couple of the other sub-harneses on the car are trash and need rewired including the headlight harness. The headlights are not on a relay and the switch on the dash is like ~25 amps and melted because porsche couldn't be assed to use the right gauge wire or do shit correctly. 


I got the hood pins installed.


I have a bunch of welding I need to do to the chassis where I need someone to watch to make sure I dont catch the car on fire. 


This includes the cage, the rear seat brackets and the hood pin brackets that are mostly just tacked on right now.


I have to re fabricate the water lines the situation right now is no buenu.


I roll on flat blacked the piece of shit tonight.


I'm kinda tired of fucking with it TBH. Feels like it's never going to be done.

Bought stuff to start building the new gauge cluster. Using an arduino with a can-bus sheild for tach/water temp. I've got a marine GPS unit for 38 bucks off ebay that is 16,000 pulse per mile that I'm using for speed. The pixel ring will be used for a visual tach representation also.  I've got a 4th numeric display I might make cycle through a few things with a radio button.

I was just going to take some plastic and cut out gauge holes but then I couldn't think of how to mount it in the dash without looking like assholes.

I wondered if I could fab some shit up for the displays to fit in the stock bezels in tinkercad and it looked like buttholes  but wasn't too bad but the polygon count is absolute trash in tinkercad.

Some dude told me about autodesk fusion (free for hobbiest) and I made a base bezel to work off then added the gauge shit in and I'm pretty happy with them.

Almost all of the dash shit works now. If any of you guys want to do the same type of shit, it can be ported over to most other odb2 cars pretty easily. Pre odb2 would need to abuse more analog inputs and would require some custom circuitry but it's not rocket science. Just voltage dividers and pulse counting and shit.

I had to fight for a few days to finally figure out how to talk to the new adapter.

 It turns out J1850 VPW has an extra header byte so I had to shift the indexes on where I was pulling data on my serial calls.

Voltage isn't working right now but it's trivial to fix. I need to figure out how to get it to poll a little faster to make it run more smoothly.

Right now the solution has been to add a counter function to the calls and only poll IAT, water temp and volts once every 400 loops and poll rpm every loop.

It should run a lot faster. There are people who have been able to get 26ms latency with this controller. I might need to flash the firmware to be able to kick the baud rate up.

If I could get a sample every 50ms I think that would be smooth enough. If not I suppose i could just add some smoothing function to the visuals on the tachometer? IDFK.

The speedometer is GPS and runs off a completely different arduino so I can dedicate its functions to reading every single pulse without having to add a one second delay in the loop of the other arduino for pulse counts. Ive tested it quite a bit and it's very accurate. Fortunately I didn't need to write a lot of code for that as I was able to just use another speedometer program someone had made for a toyota and an arduino and change the math on the pulse count pin for my GPS sender.

Here's the main code I'm currently using if you fgts want to try something. If you try it on anything not J1850 VPW, you're going to have to change the rxdata index to 6 instead of 9 and 6 / 9 on the RPM instead of 9/12 due to GM having an extra byte.

Looks great, displays look bright, do they dim when headlights are on?

On the rectangle blue screen are the number easier to read than they appear, on my computer screen?

Are you going to do a step by step write up on the displays?
Title: Re: Porsche 944 ls swap
Post by: rawr on December 04, 2017, 09:28:24 PM
The blue lcd is pretty easy to read. I haven't added any code to dim the lights off of a headlight switch. Believe it or not they're only at about 50% brightness there.

With the ECU not attached to a  GM bcm, I'd have to add an analog pin with a voltage divider to the headlight circuit todim them and add a couple more lines of code. Wouldn't be that big of a deal. I've still got that tinted plexiglass to cut for inserts on them. I haven't had time to go down to the glass shop to have them cut it.

I might do a write up. I wouldn't be sure how balls deep to go on it though.

Here's a video of the speedo from a short pull after.

No more fuel pressure drops so once I run this shit gas out of the tank that I caused cleaning it and install the wideband it should be good to tune.

The steering wheel jitters brings back memories of first drives after being bought not running.
luckily the win of getting it mobile outweighs the depression of realizing they always need bearings brakes and bushings.

You need to add the voice of kit talking to you for the dash, not sure why but it reminded me of knight rider

I needed a center console and was just going to build it out of sheet aluminum  but I didn't really care for the way it turned out in the car

(https://i.imgur.com/fRMsGIr.jpg)


Then I bought some foam and shaped something up that kind of fit the old dash.


(https://i.imgur.com/LIbJzlB.jpg)
(https://i.imgur.com/Am1uthk.jpg)


I was going to coat it in fiberglass then bondo it and paint it but fiberglass resin was like 40 fuckin dollars without the sheet.

Went on ebay, found a sketchy carbon fiber kit and poison gassed my entire house with vinyl esters.
(Do this shit outside always, the chemicals are nasty and permeate through everything)


(https://i.imgur.com/JgARHLx.jpg)
(https://i.imgur.com/kwaetKk.jpg)
(https://i.imgur.com/H5qh0bn.jpg)

I didn't vacuum bag it or anything. The sheet wasn't large enough to do one clean pass cover either. It's probably the shittiest thing ever made out of carbon fiber in existence.

(https://i.imgur.com/D5kMzRn.jpg)
(https://i.imgur.com/UKZnWS7.jpg)


I found a second seat on ebay for cheap and it matches the drivers seat so I went ahead and got that installed yesterday.

The factory seats in this car were rusted to the floor pan due to the battery tray leak so I went ahead and just made little metal tabs and welded nuts to the back. I cut out what I needed to on the stock mounts and welded the the tabs on.

(https://i.imgur.com/mHky4so.jpg)
(https://i.imgur.com/0T9uk0v.jpg)

I finished all the stereo wiring  and installed the rear speakers and mounted the stereo up under the dash. I'm using a kenwood marine bluetooth amplifier so I don't have to have an actual car stereo and it takes up only a little panel space.

(https://images.crutchfieldonline.com/ImageHandler/trim/620/378/products/2015/3/113/g113M1824BT-F.jpg)



Went ahead and installed the other door card I made as well

(https://i.imgur.com/Ab7DPBK.jpg)



I had some problem with my gauges I made not displaying the car voltage. The chip that handles the OBD2 communication measures voltage but it doesn't return hex bytes like OBD commands do so I had to write the function a little differently to get it to party. It probably took me like 3 hours at least sitting in a freezing ass car to figure out what the fuck was going on.

(https://i.imgur.com/hdVZ7kM.jpg)
(https://i.imgur.com/sgq8VXq.jpg)

That's just a regular serial stream going to the controller without seeing any return data.


(https://i.imgur.com/F1dUJ1Q.jpg)

This is printing the returned data from the chip and you can see how it's just not returning the same thing after receiving that ATRV command for some reason.

It's like one of the serial commands was not terminating correctly causing all the data to not be sent right until it failed enough times for the requests to line up again.

I finally got it though and now the voltage command for the STN1110 command fucking works and I can display it correctly.

Still having some  issues with the fuel tank, but I think the sender just isn't working correctly due to it being old as fuck. I tried to clean it and I measured the resistances of it and coded accordingly but something else is effecting it in the car that I haven't had time to go over yet.


(https://i.imgur.com/Ixq3RZq.jpg)

(https://i.imgur.com/nfPSjkC.jpg)

cleaned up the engine bay a little today and started epoxying shit to the panel so I can get those little gauge displays mounted on it.

(https://i.imgur.com/SnHEetS.jpg)


I heat wrapped the oil and water lines near the headers and did a couple unseen things but it's coming along nicely I think.

I still need to get the wideband installed and clean more shit up.

it's getting dialed in as far as the engine goes and is feeling way better than it was. It pulls like a mother fucker in 4th where the gearing is wide enough to make use of that torque.  Got the wideband installed yesterday and sent some more logs to jd.

It's a transaxle so the transmission is over the rear wheels. I've got a turbo box in going to go pick up next weekend. It will suck to lose the lsd but it should hold that power fine

Swapped the transmission to a transmission from a turbo today.

 I lost the LSD, but it shouldn't explode the ring gear anymore :noel:


Went and took some more pulls. Most aren't WOT but the gopro doesn't really do a good job of showing how close cars are infront of me.

The gears are much wider now and it feels a lot better with the v8.

I've had nothing but issues with spec clutches. Less then 500 miles and it fraged itself for no reason. (Stock v6 99 camaro) but it was out of warranty (not that they would have done shit anyways) friend insured on putting another in and guess what? It lasted 600 miles this time. New throw out, pilot, pressure plate, flywheel and all that jazz. Still killed itself. And it's not like he didn't know how to drive it. He put 100k miles on it with the stock clutch. Fuck spec clutches. They are garbage.

Good luck hope you get it sorted out. Would be a shame to dump that car after all that work.

I worked on it a bit yesterday and got the motor 90% out I just need to unbolt the subframe. It was hot as shit today so I didn't bother.

If it's the disk, that sucks because there's not really a lot of options for a disk.

I pulled the engine out. The clutch looks alright. The throw out bearing was melted and in about 30 pieces.

I think the clutch smell may have just been the clutch slipping a little from getting a bit of brake fluid on in?

I got a new slave cylinder already. I'm going to throw the spec shit back in.
 
I'm cleaning up all the ghetto bullshit in the bay while it's all apart. Hiding some wiring, moving the prop valve under the master cylinder, doing the brake lines better, cutting excess metal out of the bay. Maybe painting the engine and throwing a cam in.   :-X

I added a battery kill switch and a distribution block for the positive leads.

I cleaned up the harness as well, but you can't really tell.

That prop valve is getting moved. It's like that because I had the engine in and then realized I needed it if I didn't want like 70% rear brakes with the mustang master cylinder.

My fucking expensive ass ceramic coated headers were rusting and flaking off so I sprayed those bitches with silver VHT header paint and my beautiful Y pipe. :mexi:

I only have like 4 hours in to it but I do this kind of shit for a living.  It's pretty simple.

Definitely digging the center console, I didn't realize they sold kits to do that yourself so that's pretty cool.

Sucks about the slave cylinder but good to see it's back together.

In for more test drive vids

The carbonfiber stuff is nasty. If you try to mess wi th it make sure you have a good open area with a lot of ventilation.

cleaned up running bay

I also riced the car out. The wrap is put on very poorly because IDFK what im doing but the main purpose of it was to keep the sunroof from leaking.

I siliconed it all up but the sunroof is plastic and expands at a different rate than the car roof so the silicone tears and lets water in.

I haven't done much with this bitch over the past couple years but I did just put a manual rack in it and sorted out the idle issues.

Still could use work around the cooling system, a tune to make it not smell like a lawn mower and someone who cares enough to do some body work to own it  :P
