Car stumbling and not wanting to go

[Boosted DSM 32]

My friend just got a 97 Gst with an evo III 16g and when he's in boost its blowing oil like hell the oil feed and everything is tight and secure there's no shaft play in the turbo so I thinking maybe the seals are bad in it, and when hes in boost the car doesn't want to go anywhere? It'll be at 12 psi and the car just barely accelerates any idea of what it is? It's like there's no timing at all or anything

Might want to do a compression test first to see what numbers its throwing. Check the timing as well cause it does throw off the turbo when that happens.

What do you mean its blowing oil like hell, does it blows oil to the motor (all over the place) or it smokes.
About not wanting to go anywhere when boosting, Do a boost leak down test, You might have a really bad coupler or loose coupler that once you boost, it releases all the boost and will not go any where, doing a boost leak down test will tell you what's going on.

My 14b gave a shit out of me, it had to much play and end up not boosting, It never blow any smoke though.

Also give us more details, does it has the balance shaft removed?, how much oil pressure it has, any restriction to the turbo line, is it feed it from the head or oil filter housing, just give us more information which we can't see your friend's profile.

What both these guys said above, it also sounds like it could be as simple as a boost leak. I would check the timing and go from there...

It's oil feed is from the head it does have a fmic on it ill have him do a boost leak test and compression test and see how that goes.. And how could you check the timing without logging software? And about the oil I think the turbo is shot or there's a hole in the return line because its blowing really bad

I think you should start by first fixing all the problems you already know about.
