I used to post here a while ago..but lack of money to rebuild my civic has lowered my activity in research on turbo stuff. fortunatly my other car was destroyed by some idiot driver and i now have a sweet insurance check to spend on my civic. so..

I want to finish my mini me conversion+turbo kit. I tried looking up my old posts to find questions I asked before but came up with no results. So if you guys would be cool enough to help me I would appreciate it.

Project goal: Run a turbo mini me on my 93 hb cx. low budget low boost. higher reliabilty/less chance of exploding engine.

Turbo: small. dunno what kind? maybe dsm. my roomate can score a wrx for cheap

PSI: 5-6. not sure which turbo is good for this since most factory internal wastegate stuff is like 8psi

Intercooler: pref none..or a small one like a saab if I really need it.

Management: This is where i need some real help. only want to run the 5-6psi. so cheap and easy is best. Was thinking an fmu (not sure which rate) for simplicity. I have an electrical engineer friend that has an eprom burner..but my knowledge of that management is minimal at best.

Other q's: which head gasket should i go with the d16y8(10.4 cr) or the d16z6 (10.1 cr)?

with this amount of boost psi what kind of timing retard do i need?

If any you guys want to give me some advice that will be great. Im gonna keep searching and try to find more info as well.

thanx

 

you could just use a manual boost controller to lower the boost. I will be putting a wrx turbo on my y8 this weekend. I'll let you know how it turns out

 

nice! what kind of management you running? for some reason I thought manual boost controlers only allowed you to increase the about boost. like all it does is decreases the vaccum to the wastegate so it will stay closed longer ie giving more pressure?

 

boost controllers only raise boost. that dude has no clue. for 5-6 psi use a fmu and no intercooler. should be able to throw a low budget kit together for like 500 bucks.....

 

cool. thats actually what im shooting for a budget. any idea what kind fmu rate would be good?

 

10:1 should be fine

 

you can't lower boost this stupid manual boost controler.............. you have yet alot to learn bro :P

 

my bad. I guess i do have no clue :P. I'm new to all this turbo stuff too so i'm still learning. Isn't there someway to adjust the internal wastegate to run less boost? Personally i'm going to just run the stock 8psi that the wastegate is set at for now. For fuel managment I have an obd1 conversion with a socketed p28. I'm gonna run a boost program I got from hyperduck tuning for now until I get around to tuning the car with uberdata.

 

I am not trying to take over your thread but i had a question. Is it possible to build a budget/custom turbo setup for a B series motor around the same price range(500-800 dollar). If so how reliable would it be?

thanks

 

if u go external wastegate u can put a few layers of gaskets between the manifold and wastegate to lower boost. fmu work would work and be cheap for 5 - 6 psi. Id go with 12:1
