boarderline Posted March 12, 2012 Share Posted March 12, 2012 hey guys, so I am building my z32 rb25det project and trying to find a good trim for a turbo. I would like to be in the 400hp range but dont want the turbo to take till 4000 rpms to spool. I have aftermarket intake manifold and turbo header. I was looking at maybe a gt35 with t3 flange, .70 compressor ar and a .63 exhaust ar, what do you think? Quote Link to comment Share on other sites More sharing options...
PMC raceengines Posted March 12, 2012 Share Posted March 12, 2012 (edited) I like to fit the gt30.76R for the RB25 comes on strong and is lodes of fun to drive ,, i like to have the .82 rear housing ,with 3in exh and good cooler and tune 280 kwatw at 16psi Edited March 12, 2012 by PMC raceengines Quote Link to comment Share on other sites More sharing options...
boarderline Posted March 12, 2012 Author Share Posted March 12, 2012 Thats pretty big. What rpm does full boost at? Quote Link to comment Share on other sites More sharing options...
PMC raceengines Posted March 12, 2012 Share Posted March 12, 2012 (edited) no its lots smaller than 3540 and much stronger in the mid range. it will come on 800rpm better than the 3540, the gt35 starts to go at 4000 and will go well all the way to the red line and will make lodes of power ,but there a bit slow to respond its, a much better turbo on a 3L rb30 Edited March 12, 2012 by PMC raceengines Quote Link to comment Share on other sites More sharing options...
boarderline Posted March 12, 2012 Author Share Posted March 12, 2012 Oh! Well I love to Autocross and so I am looking for something that responds pretty quick. My header has a t3 flange, will the gt3076r's t25 flange still bolt up? Quote Link to comment Share on other sites More sharing options...
PMC raceengines Posted March 12, 2012 Share Posted March 12, 2012 (edited) you can order it with t3 flange ,,,there are lodes off rear housings for them i like the 3in outlet v band Edited March 12, 2012 by PMC raceengines Quote Link to comment Share on other sites More sharing options...

PMC raceengines Posted March 12, 2012 Share Posted March 12, 2012 garrets main web page ,, btw the gtx3076 is even better but costs a bit more , all gt3076 have no rear housing you have to order the rear to sute your needs . try garret by huneywell and go to products Quote Link to comment Share on other sites More sharing options...
