The Bluebird manifold is good only for mounting a T25 turbo on an SR20. If you try to put any turbo larger than a T25 on a Bluebird manifold you will run into clearance problems between the compressor housing and the block.

You cannot even put a GTi-R T28 on a Bluebird manifold without interference! Now if you get a GTi-R manifold you have a little more freedom because this manifold places the turbo out further away from the block.

If you want to mount any hybrid turbo using a T04B or T04E compressor housing you have the have the turbine flange cut off and rewelded at an angle so as to allow for clearance between the compressor housing and the block.

By the way most factory turbos are SHIT. I would not recommend raiding a junkyard and putting an older turbo on a newer car even though it fits. The A/R ratios and wheel trim will not be optimized for the operating range of the engine you are working with.

My advice buy a T28 or spec your own T3 or larger.
