Gotta say, i know these cars pretty well but when it comes to the numbers and sizes of turbos i'm pretty lost in the dark anyone tell me if this would be suitable for my Rx7 turbo?

GT28RS turbo


. brand new never been used
. bolts on ka-t and ka24det and rb20det set ups
.60 A/R Exhaust
.63 Compressor
Dual Ball Bearings
Ceramic Ball Bearings
.67T Compressor Wheel Capable of .59 Lb/MIN Airflow
Boost at 2700 - 3500
Oil and Water Cooled
Internal Wastegate @ 12 - 16 Psi
HP Rating UP TO 575

With the necessary modifications would this turbo be suitable for the car? Pro's Con's?

 

That turbo will provide really quick spool, and good midrange.. with bad topend.. the .60a/r exhuast side is too small and so is the compressor side..

Something like a GT35R would be better, and provide a nice topend.

 

Ah, okay perfect thats exactly what i wanted to know! Thanks!

 

The GT28R comes with a t3 flange anyways which no one makes rotary t3 manifolds. you have to go atleast t4 because the amount of exhaust gases our cars put out. I was looking at a t4/t40e for my setup.

 

whats a t40e lol just kidding t04e haha

 

the gt28r actually comes with a T28 flange, which is slightly smaller than a T3.

fwiw, you can get away with a T3 hotside, but you'd probably want the biggest one available. and yeah, as idsigloo said, t3 13b manifolds are really rare...

 

TOO SMALL.
The 13B can spool TWO GT28RS's.
