S15 5 Speed into S13 Redtop SR20DET

[AshtonR33]

Hi guys, just got a quick question regarding the SR20. Does anyone know if an S15 SR20DET 5 Speed Transmission, will bolt straight onto an S13 SR20DET Redtop? Im looking to do this with relatively little fabrication and custom stuff, but if its needed then i will do it. Thank you very much.

Are we actually talking about the S15 6 speed?

[AshtonR33]

Oops yeah I think so haha. Is there a 5 speed sr20 gearbox which say, from an s14 would fit directly to the s13 redtop? 

[GTSBoy]

Yes. That would be the same 5 speed as the S13, basically.

The 6 speed should bolt up to an S13's SR, but I won't make any promises on it fitting gearbox mounts, shifter holes, etc, because I don't know for sure. But it should be able to be made to work.

Okay thanks mate. I was just looking into some gearbox options and found that I’m potentially going to upgrade later so I might as well stick with the oem stuff until I upgrade the engine. Thank you very much
