I was refered to this forum by a member of CB7tuner, and I thought Id share my setup.
Hi, I am Honda Bob. I am a tuner in the cleveland ohio area. I work with the guys from Big 3 Racing, and I dedicate this build to them. They helped me out with a lot of stuff, including shop space, tools, and moral support.
This is my 92 accord ex build. I am about as diehard of a honda guy as they come, but I've never had an accord untill now. I needed a winter beater bad, and I picked this car up for 200 bucks with a blown head gasket, and that is all I knew of at the time. The car had 208k on it. After getting it, and putting a head gasket on it, I further inspected the vehicle to find it needed new trailing arm bushings, rear brakes (the one rotor was cut off the hub), upper and lower ball joints, stab link bushings, trans (no 3rd gear), clutch, egr control solenoid, o2 sensor, and quarter panels. All of that is no big deal at all... The real problem is, I cannot leave well enough alone.
I have fixed about everything except for the rot, and made the car safe. At the same time, I realized the car needed more power, b/c it was terribly slow. My other project car (race car) is a 400+ whp sohc civic. (35psi off a borg warner gm8, no joke) This car was a complete dog, but I fixed that.
This is about the best whole car pic i have right now.
I definatly went turbo with the build. I picked up a ported evo3 16g, manifold, o2housing, heat shield and j pipe for 90 bucks, Every bolt hole on the turbo was stripped out, and the manifold had a couple cracks, but all that was fixed.
When I went turbo, I decided I was not looking for the biggest hp number b/c I have my civic. I did want torque though. I also wanted the shortest charge piping possible to keep lag to a very minimum. I ended up using a ford turbo coupe intercooler and placed it where the battery goes. I relocated the battery to infront of the passanger tire, and made a battery tray out of angle iron. Here are a couple pics.
The engine bay, after first boosting...
With the intercooler where it was, I needed to get air to it. I am planning on going to an evo style cf hood in the future, but untill I do, I did this...
This was my first TIG welding project. I learned on this hood.
I could not match the paint at all, so I went for some contrast. I love the VHT flame proof ceramic paint, Its like a satin color with a little bit of shiny grain to it, like sand paper. Its hard to describe, but its not just plain ole flat black.
On the tabs that go inward, I'm going to get vynl made up that says Turobcharged for the driver side, and INTERCOOLED for the passanger side.
I replaced the trans with a good ex 5speed, and installed a new flywheel and Spec stage 3 clutch, rated for 360 ft/lbs of torque.
I highly reccomend spec. They hold up. I origonally installed a centerforce dual friction, but the bitch would not disengage at all. I returned the clutch at summit racing (i live 40 minutes away) for another centerforce dual friction clutch, thinking it was a fluke, and it too would not disengage. At that point, I swore off centerforce, because I had to remove the clutch a 3rd time, pulling the trans a second time unnecessarily. I ended up springing for the spec, and im glad I did. It has great engagement, and its not too rough. My whole goal for this car was to maintain stock driveability, just with more power.
I then headed to the egr box. I raped the shit out of it, removing the internals and replacing the guts with a omni power 4bar map sensor and a MAC ebc solenoid (fuck AEM, they sell this solenoid for 90 bux. We did the research, found the part number, and picked it up from a local MAC distributor for 13 dollars.)
Now for my absolute favorite part of this build, My Exhaust. Again, I wanted to maintain 100% stock drivability... But at the same time, I wanted to put some numbers down at the track. I ended up thinking of the cutout. It was made of scrap piping laying around, and turned out amazing. I have a 2.5" downpipe (made before the cutout) going to a 3" pipe. In the middle of the cutout pipe, I have the stock 2" exhaust with cat spliced in. I have the 3" pipe running under the car, and it spits out right behind the passanger front tire, with a block off plate. When the plate is on, the car runs stock exhaust, and I cannot hear the engine running when driving down the road... how it should be stock. With the plate off, Its balls to the wall. I love it.
I know the exhaust flow from the downpipe to the stock exhaust is far less than ideal, but again.. I dont care. I just want it quiet for when I'm not at the track.
The car is running off of eCtune in a po6 ecu modified for ebc, iab, and 0-5v o2 datalogging,
On 9 psi (all the stock exhaust could flow) the accord put down 180whp and 220wtq on a mustang dyno. On open downpipe at 15psi, (at the time it was before the side exit, the 2.5" downpipe cut right after the o2 bung, witch was right after a 2" flex section) the accord put down 240whp and 270 wtq.
On the dyno, It ran a 13.8@101... with a 1.7 60'...
The 60' was not realistic. So far, on low boost, the car has posted a 15.03 @94mph with a 2.3 60 ft. I have no high boost runs in yet, due to mixed up electronic boost control settings.
This is my favorite part of eCtune.. Antilag.
(sorry for the low quality, cell phone for the lose)
Most would be pretty happy with this, however I'll reiterate that I cannot leave well enough alone.
With the DSM turbo mod, you need to remove the front torque mount. You do need this mount, and I did not want to see it go, but boost won in that arguement. To compensate for the lack of a mount, and to keep wheel hop to a minimum, I made an extra mount. It replaces the cross member support bar, and It now bolts right up without any modifications to the crossmember or engine, its basicly a bolt on situation.
With the new mount, I noticed an instant improvement in traction, and the over all feel of mashing the throttle was much improved. I didn't feel the engine slopping around in the engine bay any more.
While datalogging some high boost pulls, I seen my intake air temps were climbing pretty high. After a pull or two, the intake temps were close to the 220*f range... The intercooler is just not large enough. Since I already commited to cutting my hood up, I couldn't run a front mount. I will not support any exterior mods that do not have a purpose.
So, the logical step would be Meth Injection. I do not see a need to pay 300+ for a meth injection kit when I can make one myself. I found some Jeep Liberty FFV injectors layin around, witch will stand up to the methanol, and made some bosses for the charge piping,
(I love my newly acquired tig welding skills...)
When I researched the Snow meth kits, they use a 150psi pump and one nozzle. With my kit, I used a factory honda pump, fuel pressure regulator, return line, made my own "fuel rail", and 3 injectors. The meth pressure will be in the 50psi range, and with 3 injectors, it should be comparable flow (atleast thats what I figured out in my head, lol). I also have each injector setup to fire individually, depending on engine conditions. The injector before the intercooler will fire at 3psi, WOT. The second injector will fire at 10PSI, WOT. The third injector will only fire if intake air temps get above 150*. I honestly haven't had a chance to tune this on the dyno yet, but best believe I will have some dyno charts and a video up when I do.
As for a tank, We used an old hydraulic pump case, modified to bolt a factory honda fuel pump sending unit to it... witch as also been modified.
Here's some more DIY meth injection pics...
Thats about all I have right now, but stay tuned. I ended up aquiring a wristpin knock (maybe) when I was trying to get my boost controller settings to work at the track. I spiked 18psi while antilagging, popped the head gasket, and the knock was heard as soon as I installed a new head gasket and ARP's. I now have an f22b sitting on the ground in the garage, and sometime next week its going in, along with the meth injection tuning and 20psi. I'm expecting 300+whp, and 320+wtq. We'll see, but when I do, I will post up some new pic's and videos.
I appreciate any comments, and I will answer any questions you guys may have.
