It's not pushed up tight in the picture there, but when I do push it up tight, the compressor housing hits the LIM. I need about 1/2" more of clearance, no matter how I clock the turbo. Now, the big question...... what to do?

the way I see it, I have two options.

1) Cut up the spare turbo manifold I have that's trashed anyway, and use it to make a spacer.


2) Grind on the turbo a little, and grind on the intake a little.


I would rather just take material off both the turbo and LIM, because if I remember right, the downpipe fits pretty tight as it is, and I don't want to throw it off. But my only concern, is there enough material in the intake to work with? What would you all suggest (aside from switch the stock compressor back onto it, obviously that would be the easiest solution, but also defeating the purpose of this).

It's pretty common to need to grind on the compressor housing when you go with a hybrid. It's usually one of the big chunks of metal that is there for one of the bolts that causes the problem. Try to grind off only what you need to clear, but even if you have to grind the whole thing down and leave the bolt out, it will not cause a problem because there are 5 other bolts.

I think the easy way to fix this problem would be getting a RB flange as your spacer, and just get some longer studs for the housing, that will give you the 1/2in you need.

Adding an adaptor would throw off every piece of plumbing on the turbo. Oil supply, oil drain, coolant supply, coolant return, possibly downpipe and even intake/IC plumbing. This would take time and money to resolve, not to mention the cost of the adapter and extra gaskets.

Grinding material off the compressor housing costs almost nothing (except for bits etc.) and would have no adverse affects.
