Cubes Posted August 14, 2006 Share Posted August 14, 2006 Depending on turbine housing size but with a guess, .82 close to 6.5k and .63 maybe close to 6k? It is a stab in the dark but it wouldn't be too far off. The GT35r is a big turbo for a little 2ltr.

Cubes Posted August 14, 2006 Share Posted August 14, 2006 No point going a turbo where you wont use the airflow capability. Unless your willing to either drop in an rb30det or at bare minimum throw a set gtr rods and crank at your rb20. On the 3ltr the gt35r kicks nicely at around 3.5k.

R31Nismoid Posted August 14, 2006 Share Posted August 14, 2006 GT35 far too big for RB25/20 if you intend to have it as a street driven car Link to comment https://www.sau.com.au/forums/topic/130273-gt3540/#findComment-2410005 Share on other sites More sharing options...
carl h Posted August 14, 2006 Share Posted August 14, 2006 gt30r is a much better turbo on the rb20... Link to comment https://www.sau.com.au/forums/topic/130273-gt3540/#findComment-2410033 Share on other sites More sharing options...
HypeR33 Posted August 14, 2006 Share Posted August 14, 2006 my 3540 comes on full boost after 4.5k, so hate to think what it would do on a rb20. Dont think you will get much use out of it.
