Turbo question

[Island180sx]

Hi guys. Quick question. Which one of these turbos will bolt straight on or need a little modification to fit the RB20DET

Garrett GT2560RGarrett GT2860RS

Both are used in the SR20DET.

Any T3 flanged turbo will bolt up to the 20/25. I believe those are T2 flanged by default, but you may be able to get them with a T3 flange...

I would suggest you do your homework on turbo selection before you make your final decision. There are some good threads here and on Skylines Australia that cover rb20 turbo selection, power output, etc..
