Ok here is a question.
all you nackas with your SR20s say T25 and T3s cannot be switched out. Well.
How come on a Z31 84-87s have a T3 and 88-89s have a T25 and the exahust manifolds are IDENTICAL??
I am looking for a cheap upgrade to the T2 small on a friends motor.

***Even though the 84-87 Z31 had a T3 turbine housing the flange was still a T25. That is why it fits on the newere 88-89 manifold without modification.
Just like you can get an HKS GT3037 with a T25 or a T3 turbine inlet flange.

Jay you see what im getting to.
;...
would that mean i can put a 84-87 Z31 T3 on the bluebird turbo manifold?
because I can get great smaller T3T4s based on the 84-87 exhaust housing and they will bolt on to the bluebird manifold internal wastegate and all!
Lets do this.

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.
Peace

Cool what are the specs on these bad ass turbos? What A/R is the turbine housing? I would not go any lower than a 0.63 A/R on an SR20. If you go with the 0.48 or smaller on an SR20 there will be way too much backpressure and the engines volumetric efficiency will suffer greatly.

.63 or .78 or .81 depending on the housing that is used
but the s130/z31 is a .63 which is great.
i just wich i had a picture of the flange
