Nice job man...you had a lot of thinking to do to route the charge pipes.
With the turbo in the back seems to be a really difficult job.

i'm not a huge fan of the 2.4L. My friends 99 Z24 (100% stock) broke the crank shaft in half for no reason, lots of oil and regular changes. He now has a free reman'd 2.4l from GM. We'll see how that one lasts.

As for loosing some boost in higher rpm., with a 42,48 it can't supply the boost, especially to a 2.4l. switching to a 60 ish would help tons.

Guys thanks for the props that means a lot to me. I really wasnt impressed with my own setup but maybe I did better than I thought.

Yes the turbo is small but I doubt its too small for that amount of boost. I ordered a cheap boost controller from ebay last night. If its at home on friday when I get there I'll take 3 seconds and hook i up, test it out and turn it right back down again! lol.

I'm just happy with the car since I did it all myself, everything from body..engine, paint etc. Anyways I will get the boost controller and check that.

Jeff, I did check the wastegate for cracks when I had it all apart. I saw none and this turbo was in great shape. Minimal shaft play, no chipped or bent fins it really did look nice inside. The wastegate actuator looks brand new as well...I'm thinking the one they replaced it with was just not set at the factory 7psi...but who knows. I just know that I should on friday.


A larger turbo is in the works for later. I have a turbo from an 86 Tbird 5pd which was the 60/63 one. It needs a rebuild I think thats the next learning experience I want to accomplish.

Oh so everyone knows I made a downpipe and made it route to my very small sized stock exhaust for now.... No bov either so when I let off the gas the turbo is saying "where the ---- did this wall come from" haha

It's your stock exhaust causing it to die out at higher rpm's I had the same problem I used my stock 1.5 inch exhaust for the time being well I couldn't rev past 6500 rpm I took it of and drove it with open down pipe ....it took the lag away and it boosted to redline

Thanks again, part of why I love this site so much. I always seem to find more answers and better help on your "honda" board compard to the good old jbody.org

I should have thought about the exhaust, maybe sometime I will just remove it and redo it again. I went from a 2 1/2" downpipe to 1 7/8" pipe right before the cat converter I believe.... I have a new muffler and everything I plan on going 2 1/2 or 3" all the way back but like many things I just dont have the time currently

Thank you again guys. I cant wait to get my hmt stickers when they get here

You can directly swap the .63 exhuast housing from your turbocoupe turbo to your volvo turbo. I would know, I have both ( and a GS-T T-25, and a wrx, and 2 14Bs on the way ). The .60/.63 turbo has the same everything, its just got a bigger a/r on the exhuast ( I mean the same stuff on the "hot side" anyway ).

My volvo turbo T3 ( .42/.48 ) needs rebuilt and I think its too small for my needs, so when I took apart my "SVO" turbo I used the exhuast housing off my volvo turbo to protect turbine wheels on the perfect condition SVO turbo.

If you only wanna run 5psi, then thats a pretty good turbo for you IMO, but if you wanna run alot more, then I think the .60/.63 is in your future.

Hell, I'm going to run a .60/.63 on my SOHC 1.6L !!!
