Default LSThatch/Blacktyper01 Turbo V6 Hatch build

Pardon the huge first post, just want to catch everyone up on the build thus far. Originally posted this on J32a.com:

I completed my first stock J32A2 swap in my brother's car a few years ago ... I posted a few pics of the cowl hood on j32a ... now it's our turn ;)

blacktyper01 and I have combined our efforts to produce a turbo v6 eg hatch. All work (fab, wiring, tuning, etc.) is done by either him or myself with some back up assistance by any extra hands that happen to stroll through the shop.

A little back story ...

car started it's life with us a few years ago when we fabricated/installed a built LS/VTEC turbo setup in it for a customer:
- 10pt cage
- 5pt harnesses
- battery relocation
- parachute mount
- dual Bosch 044 pumps
- Precision intercooler core with custom end tanks

the engine had a catastrophic failure at 40psi of boost and the owner sold the chassis and part of the turbo setup to us.

After the first few weeks we decided to install a bone stock J32A2 swap (M/T) and ended up with a best track pass of 12.53 @ 109.6mph at our local track.



Then we decided to install AEM but (since our local track closed down) we have been unable to run it. We changed over to an auto motor/harness and cleaned up the wiring a bit to ease the use of the plug-n-play EMS system (darn cam and crank sensors):




We also cut down the water neck and customized the radiator to make room for our future plans ;)






The idea was to see what we could get out of the car on the stock motor and AEM. However, being as impatient as we are (and that fact that our local track got closed down) we decided to just go ahead and turbo it ... here's the first teaser pic (the turbo's a bit heavy so, yes, we used a seat belt and engine hoist to hold it in place, lol):


We were thinking about custom fabricating an IM but, in the interest of time, we went with a port & polish of a stock A2 IM, plus port matching the inlet to a 75mm Edelbrock throttle body:




upper IM being all cleaned up ... we removed the butterfly system and sealed the EGR port too.

the beginnings of the turbo manifold:


Making the collectors:








Test fitting collector on manifold:


Turbo mounting bracket fab:





Catch can:


Fuel rails (-8 in, -6 out ... FIC 1000cc K-series injectors):



Front turbo manifold fab:
















some more progress:

rear manifold:










-8an fuel supply line:


wastegates (2x Tial 44mm):







Should finish up oil feed line, downpipe, and hood tomorrow ... then we'll be taking it out for a spin ;)

progress before the first drive:

downpipe:



hood cutting:


hood closing and completed setup:




Took care of all this yesterday ... got it started up on AEM and took it out for part-throttle tuning last night. Everything looks great besides an overheating issue caused by our puny fan ... SPAL 13" 1700cfm unit is on the way

So, ... we threw a SPAL 13" 1700cfm unit on there and it's working flawlessly ... guess an extra 1050cfm did the trick, lol.

Took it out and street tuned it on 8psi ... runs great and has tons of torque!

Took it to the track this past Friday and did a couple 11.6 passes @ 121 mph with the clutch slipping or the tires (24.5x9" slicks) breaking loose the whole time.

This week's project ... competition clutch twin disc ;) ... more to follow

... No comments?

Well it's about time somebody replied! lol ... Thanks guys.

We are going to push the engine and transmission to their limits. I have a good feeling that 3.2L of displacement is going to make a hell of a lot of power ... ok maybe I mean torque ;)

i dont know if the imports are the same as domestics but after 3.5L the heads or headgaskets tend to break. either way, i like what i see here.

We'll see how the heads and gaskets hold up on the 3.5L in the near future.

I have high confidence in them since they are the same MLS design as all 4 cylinder Honda head gaskets and the number of bolts/studs per cylinder is higher (2 2/3 vs. 2 1/2).

That pass was a 12.11 @ 112mph ... lol

Not the best of the day but a decent 1.68 sec 60'

I love the sound, even with the clutch slipping and it running soo slow.
