i managed to put the engine in the car this weekend but.. the ss autochrome o2 housing hits the steering column and the coolant lines and the bottom of the turbo hit the steering box. what should i do? i can get a new o2 sensor housing from megan or something, but what to do about the turbo? has anyone else had this problem and if so, what did you do? will nismo motor mounts raise the engine enough? or will i need to get a new manifold? thanks!

Clearance problems...
Re: Clearance problems... (r34 gtr)
is the the twin tube design? try bending it with a hammer AKA denting the **** out of it till it clears

Re: (float_6969)
did you remove the lower turbo heat shield?
Re: (WeldingHank)
The Megan Racing one works very well. I have that one w/ t28, no problems.

sorry about the lack of info, i was at a friend's house and there were about 3 other people using the computer...
the turbo is a garrett gt28r. the manifold is stock. the o2 housing is the ss autochrome hks style separated thingy.
its hitting so badly that the engine is now stuck in the engine compartment. ill probably have to remove the steering column so i can get the engine back out.
i have removed all of the heat shields. they dont fit with the gt28 because its so big. when i was connecting up the turbo i actually had to make a 1/8in steel spacer and use 2 manifold to turbo gaskets so the compressor housing wouldnt hit the manifold. its a good bit bigger than the stock t25. its funny though because people are using gt28rs's and gt25r's without this problem. maybe i just got a really wierd turbo.

oh! and how the turbo is situated, the o2 sensor housing doesnt point straight down, its more at a 30 degree angle to the left (from straight down) if youre looking at the engine from the back. i figured the offset motor mounts would fix this but i cant really see as the engine wont fit in the damn car.

edit: oh! and i also forgot to mention that when i used my stock compressor up pipe thingy (the little one that connects the compressor to the intercooler piping. has the 3-bolt flange on side and the tube on the other side...) it sits at some crazt angle. the little pipe points almost straight at the square bulge on the exhaust-side valve cover. anyone else share this problem? i know i can just clock the housing around a little bit but i dont know if its worth the hassle since im making new piping anyway..

I think it's the turbo you're using Tim. I know that it's supposed to be real close and with that turbo, plus the extra gaskets, I'll bet it's screwing the spacing up. What I would do is slap the stock T25/8 back on there and see if the motor will go in. If it will, then its' the turbo. If it still won't, try using the stock downpipe. Did you make sure you put the engine mounts on the right side of the motor? I could be wrong, but I think they have a left and a right...

they do have a left and a right, but they never came off.
i got the turbo-hitting-steering box problem sorted out by taking a torch to the oil and coolant lines, as my dad was really cheap and re-used the hard lines when i wasnt looking. (will these lines support the new turbo? the fittings are the same but will they flow enough?).
my problem now is that the o2 housing hits the steering column. badly. like, woah. the wastegate outlet for the turbo is directly in front of the steering column, and only 2 inches away. i think i can get midas or someone to make me an o2 housing/downpipe/test pipe piece and avoid this whole mess. or i can modify the ss autochrome housing so that the separate wastegate pipe enters almost immediately.
the engine is in the car right now, the o2 housing is off so nothing is touching. i think itll be resolved friday, so its allll gravy. thanks though, i really appreciate the help. ill let you know if i screw anything else up and can't fix it myself.

Re: (r34 gtr)
It sounds to me like your turbo housing needs rotating (clocking). The oil feed hole should be right at the top of the turbo when it is fitted to the car or the oil will not flow through it correctly.
Rotating the turbo will probably give you more clearance for the o2 housing as well

Re: (buffy)
i dont see how rotating the center cartridge would help to move the o2 housing, the exhaust housing is bolted to the manifold, so it doesnt really move at all, but i do agree that the center cart. needs to be clocked the correct way for the oil to drain out properly, the oil lines need to be within 15 degrees of vertical, and the stock hardlines flow plenty of oil and water to cool the turbo. it sounds like its just the o2 housing with the separated wastegate is your problem, do you have a stock o2 to test?

yeah, ive got the stock o2 to test with. ill probably check it friday. im pretty sure my oil feed is at the top but ill also check that when i get home. hopefully i can get this thing sorted out, its ready to run except for the lack of all exhaust. i would rather not start it without an exhaust as im sure it would melt something.

Re: (float_6969)
not true, mine was leaking between the cat and DP and the heat shield was missing from the chassis , it backfired and i ended up with a fire between my legs, i now have a baseball sized burn hole in my carpet.
