does anyone know what turbos can be used as an upgrade for an S13 sr20det, using the stock exhaust manifold? i read somewhere that the T3/T04 is an option. what would this do for max whp? and any things to change for the fit?

thanks and dont rip my head off bc i dont know everything about turbos yet

Garret GT25

You will need to modify your current manifold or get one made but double roller bearings and awesome flow characteristics make this a bloody nice turbo. A guy renting from me had one on his S13 Silvia with the SR20DET in it. With only an powerFC, 850cc injectors, and a front mount he when from 181hp at the wheels to 281hp at the wheels at 1.2 bar of boost. He saw full boost at 3,800 rpms and it just pulled right up to redline with no nose over.

RazorGTR,
any idea on where i can get a GT25 for a reasonable price?
and what about that T3/T04? whp numbers?

and your buddy was using 850cc injectors? are they really necessary?

4Cyl. 300ps need 440cc each cyl.
4Cyl. 500ps need 760cc each cyl.
4Cyl. 550ps need 840cc each cyl.

what i meant is can any other turbos fit in the stock turbine housing? w/o modification?

Dont be cheap and just a new manifold to compliment that new turbine.
