Title: EJ8 build thread. the never ending flip flopper project
Post by: marcj on June 05, 2009, 06:30:23 PM
Why hello sirs! My old build thread went down with xenofags sellout. I'll skip all the actual previous work and start at where I am now with a very vague introduction, since I plan on doing so much more I figured WHY NOT?!

Some of you probably remember the build, but it's so common very few will remember the details.

it started like this:
B16A 9:1 pistons
T3/T04E 57 trim
dog turd drag manifold
dsm 450's
etc.
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fc4.ac-images.myspacecdn.com%2Fimages01%2F49%2Fm_919a1578c669d8b94084363070ebe577.jpg&hash=f03a32153d01ef100399055b226e18045ea88d22)

ran like a champ until the turbo started smoking and blowing oil out of the dp.

picked up this from a member here for $260 shipped
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fc3.ac-images.myspacecdn.com%2Fimages02%2F32%2Fm_53ede458ce364fc9a7a9a032550f603e.jpg&hash=3ac7463d3184e14c445853e5694c2db031efcaae)

decided to continue running the blown garrett because i'm not very environmentally friendly
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fc1.ac-images.myspacecdn.com%2Fimages02%2F53%2Fm_34d770671afa4732b92ef457cc2ad51c.jpg&hash=5a2c18e0068c389534b37336ea1642470a0fde45)

picked up great mid-range from the new manifold.. it actually helped spool time too

then I came across this beautiful HX35 brand new.. for $170 shipped.

had some problems with fitment.. not only was the wastegate palcement an issue, but the compressor wasn't clearing the cross member
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fc1.ac-images.myspacecdn.com%2Fimages02%2F60%2Fm_468e13cf654b415886d0cbf987f01efc.jpg&hash=5ff94e79502de8c3326b84038459ec87ba307215)

got this idea from Whitey and MADMAX

used 3" stainless steel.. more info about this in my thread in fabrication

everything fit first time.. had my local exhaust shop weld it up at no cost
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fc2.ac-images.myspacecdn.com%2Fimages02%2F89%2Fl_b0a7c8155f6646998329647696457815.jpg&hash=922dce7d6c99fd99bb7b20d034cf418bfedae1f6)

turned the EVO intercooler into a backdoor entrance.. spent $30 total
(https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fc2.ac-images.myspacecdn.com%2Fimages02%2F67%2Fl_54361b1dbab84f1889a1a5a2ca6cf4a9.jpg&hash=41d1900c7eeae691fb1cc3dc4062647b88fd514f)

Things that I will be updating on over the following weeks:

3" V-band down pipe (running 2.5" since it's all I had at the time)
3" Thermal exhaust (was waiting until I make the 3" downpipe)
reducing IAT since the sinktrap is close to my IC backdoor entrance
DIY water/meth injection system
traction bars made w/ weirs kit
upgrading to ectune  ;D

yeppp, always have.. haven't blown up a motor yet

I haven't messed with timing yet, so I leave it conservative and use JDs advice about b16's loving timing, so I added a few degrees in vacuum where they lack power.. definitely helps a bit.I may visit sewell when I step up and try for 450whp

gayballs.. the middle stud for my fuel rail snapped in two last night when installing my 780s, so now I can't get them to seal under pressure. after class i'm going to pick up an LS intake manifold to get me on the road quicker. god dammit

on a brighter note, it's ma birth day nigs!

Post by: Tim on June 11, 2009, 11:22:37 AM
but the studs do.

or you can buy a new stud at any auto store worth a shit for cheap.

Either way vise grips take out what's left of the old stud in no time.

I did the same thing and double nutted the good studs so I could get back on the road.  Swapped b16 studs onto my LS and then back once I swapped engines.

big difference in spool time with the sinktrap over just the mini ram? ive been debating on building a sinktrap for my ls turbo.  im running the 18.5 h1c, with the comp side that looks just like your hx35, so the big h1c i guess you would call it. right now i get full boost at like 4200-4400 with the drag cast mani.
Title: Re: EJ8 build thread. Holset, sinktrap, etc.
Post by: glustic on June 11, 2009, 08:12:14 PM
Im really diggin your build. Fucking tits. You should be able to do the double nut trick to get those fucking studs out, try that before the vice grips. Just remember when you fuck with a car, shit like that happens all the time. When I was taking out my IM, the middle bolt was fucking stripped, so I had to use a dremel on it for a good 15 mins to get it free.

Anyways keep us updated man.

If you run a 4-2 upper manifold and feed a split tang turbo like an HX35, the spool time will be better.

If you run a conventional/common collector design... flow dynamics change a lot manifold to manifold, but the general trend is the more manifold volume the laggier the spool so expect it to hit later.  Might be super minor, might be a good bit.  My money is on 4-500 rpms later, if you run a big up pipe that can support a good sized turbo, like I would do.

Post by: AJxr on June 11, 2009, 08:23:35 PM
thread jack but yeah

yeah my h1c has the split housing, and id be basing it off a stock LS exhaust mani which is the 4-2 top piece. and id keep her split up to the turbo. or i can just keep the mani i have now and not worry about it cracking apart... WOO!!

well, I went from the mini ram using a T3/T04E which had almost instant spool, to the sink trap using 3" up to the HX35 12cm housing, and then 2.5" down pipe.. yeah definitely a decrease in spool time, but it hauls a lot more ass after 5k rpm.

if you're daily driving, why not just stick with the drag mani if your spool time is that good?

I'll be looking for big numbers soon, so that's why I chose the bigger 3" pipe for my sink trap. most would use 2.5", but if you do the math, the volume of each runner on manifolds combined equals out to be a lot more than just 2.5", it's closer to 4" of volume total.

How do you distinguish between manifold and turbine/turbine housing spool characteristics in that comparison?

that was my point.. I cannot make an accurate assumption, but the bigger turbine house/wheel of the holset was obviously the biggest factor here. I would guess less than 500rpm of spool time was lost due to the J bend.

doesnt fit because of the down pipe? i always seemed to have cooling issues with the radiator not as far front and straight in the engine bay as can be. also though i always run half damaged single core junkers that i fixed with 2 part and a small a/c fan from an eg.... haha.

No.. it's a custom made radiator; was a full length for an integra or something, and my buddy cut it down to half size for a customer, and it ended up not fitting right (go figure).. so he let me have it.. I believe it's a fluidyne.

I'm pretty fed up with the whole fuel injectors leaking.. I'm replacing all of the studs,nuts and upgrading to an OBD1 or 2 fuel rail. The rail i'm using is OBD0 from my CRX HF project 7 years ago. I'm not in a major rush to get it back on the road since my clutch isn't here yet any way.

2ohm delphi.. yeah it was an awesome price. Holly sells them for 150 + shipping usually, but they had a sale going on which knocked them down a lot. I should have bought as many to resell.

being sexy, and looking sexy, two different things.

sending this back for a Demon RTP instead  :evil:


Finally got my replacement fuel rail studs from Honda, got them in and wa-la, no more fuel leakage. so I take off hoping to see what a 15psi pull feels like, then I realize my TPS shows 0% constantly, and is causing a horrible idle surge/throttle response/etc. so I bring it back home :(

something is keeping me from getting the proper voltage. hopefully I'll get it working tomorrow; for now i've had enough.

of course it rains all day my day off, which I had planned to tune my car.. everything is setup for 15psi, might go tune part throttle any way.  >:(

btw, I used one of JD's tunes for an 880cc T70 setup, spools my turbo 1k rpm sooner! not sure why my tune was bunk. maybe the old wideband wasn't working 100% with freelog. using PLX m300 now. love it!

damn dude... 1000 rpms earlier just from a tune? damn. our setups are going to be similar in a few months.

forged b16, 880s, holset, hah. liking this car.

The tune he used is a log manifold street tune, made 404 at 21 psi off a not so super T70.  A little extra fuel and conservative timing will help anything spool.

Yep, I figured that out pretty quick while tuning once. Add a little more fuel down low and retard timing and you'll get a faster spool up.

I have only tuned my own car so far, so thanks for the tips. I did get my HX35 with around .90AR housing to build 6psi (no MBC, just a 6psi spring) in neutral with crome and it felt like it could do much more with a MBC installed.
At least my HX35 wont be building full boost after 5k if I mess around with the map a little more.

AR measurements do not apply to non-Garrett turbos.

Goforth should have 30+ psi antilag video off the 62-1 setup.

14CM^2 housing doesn't help spool on a stock motor though.

Marcj this is a very nice RHMT setup. Hope you get the problems sorted out quick. Holset FTW.

Had some serious problems with the tune on my new injectors. somehow the TPS wasn't giving me any voltage. long story, but it's all fixed now. I had to modify an LS throttle body with an OEM adjusted TPS, and it cleared up that problem. Now that it idles, i'll go for some street tuning later when my girl gets home. hopefully I can make a 15psi ripper vid tomorrow.

The plan right now is to setup this car as daily driver friendly as possible, while keeping it boosted.. that means removal of the bigger injectors, turbo, etc. being replaced with those closer to a 300whp factory performance. The sinktrap was sold, and profit was made on it.

a log manifold from weir was purchased to accommodate the A/C compressor, power steering is a joke in my car, so it will remain absent.

also, purchased a set of 450's, so i can throw my old tune of, which drove like a stock car.


All the good stuff will be added to the 240sx, and eventually it will become my daily driver, and this coupe will be sold in N/A form, since people looking for a 4banger civic don't really care about the turbo stuff.

I will update this once it's back to a comfortable ride, just to conclude this thread, and a KA24DE thread build will start.

5500rpm logging 14.6psi netted me 320whp 245tq.

had a bum set of 780s in it and couldnt make a full pull without it leaning out. so thats the best i did that day. just put my new injects in the car today. so ill try againi soon. but yea it spools rediculously quick and it comes on hard
