hey guys i just got a 91 vr4 and love it. The car does have some probs like clutch for one is slipping bad under boost. Aslo i noticed two studson manifold broke off. The car has a weird idle it jumps around and blue smoke if i get on it and when its warmed up, But i know that pretty much is the turbo maybe bad. Should i rebuild it or just get one off craigslist. I started school for auto tech last month, and have built hondasmy whole life but getting out of the military and moving to hio, i was dissapointed by all the rice i found he vr4. I have wanted one for ever but i dont wanna do any mods just get it running right and on an extreme budget i think the clutch will have to wait because i need a dd. I have kids and a wife to get around thanks fo any info you can give.

Sorry forgot to say compression check was good.

yea i would say ur turbo..did u check for shaft play

no not yet what will shaft play indicate.

if it has shaft play 90 percent of the time that means its due for a new one or u can rebuild it

the idle problem maybe boost leaks or vacum leaks

So how do i find a boost leak? I will take a few pics of the bay and see if you guys notice anything as far as turbo what should i remove to check it out? Also would a different B.O.V. help then is it ok to vent to the air instead of back in intake?

You will need to keep the bov recirculated or your car will idle terribly. The car expects that air so venting to the atmosphere will give you lots of problems. For a boost leak, you'll need to buy/make a boost leak tester to pressurize the system with an air compressor through the turbo intake. You can then listen for leaks or use soapy water to look for bubbles.

Good luck!

he got to it before i did

can anyone point me in the way to build a leak tester.

get a hardpipe for like ur maf and cap the end with like a plug for plumbing..drill 2 holes in it one for a pressure gauge and one for a valve for u to fill it up..put a coupler on the other end of it and clamp it on to ur turbo then u can fill it up with air to check for leaks

forgot to add..recirculate ur bov to the hard pipe when testing

Gabe, but remember the 90gsx was a wolf in sheeps clothing and never could believe the vac line was being plugged with gum.... haha...
