Deano 1 Posted October 11, 2011 Share Posted October 11, 2011 why rev's? Link to comment https://www.sau.com.au/forums/topic/379780-how-much-rev-have-people-got-out-of-rb25det-or-rb20det-and-what-mods/#findComment-6055971 Share on other sites More sharing options...
O2 Autosports Posted October 11, 2011 Share Posted October 11, 2011 I'm guessing cause it sounds cool. Rb 20 crank in 25 block with gtr or stronger rods and custom forgies would rev hard and hold together.

zebra Posted October 11, 2011 Share Posted October 11, 2011 a few mm off the crank isnt going to make it rev like a sport bike. what about oil control + the 11ty billion other problems that will surface Link to comment https://www.sau.com.au/forums/topic/379780-how-much-rev-have-people-got-out-of-rb25det-or-rb20det-and-what-mods/#findComment-6056067 Share on other sites More sharing options...
R31Nismoid Posted October 11, 2011 Share Posted October 11, 2011 Ye there is some serious investment that needs to go into the head. Just a set of springs really isn't going to cut it for extended 9000rpm+ sounds good. some 290 degree cams maybe? Well 290 degree cams give you 1000rpm response over any other choice according to some around here, so they should be the first items purchased!

JustinP Posted October 11, 2011 Share Posted October 11, 2011 Hahaha.... But seriously you want revs and you don't care about power or response... Buy a Honda with vtec yo, or for even more fun, go an give yourself a tax audit.

The Bogan Posted October 11, 2011 Share Posted October 11, 2011 Or use the money you will need to spend on it rev to 9k for any extended period without lunching itself on 5 stock motors with boltons like most skidders do. Lunch a motor, swap in a new one, simple. Do that.

N1GTR Posted October 11, 2011 Share Posted October 11, 2011 The most insane RB track car I've ever heard, as well as a large amount of guys from the drifting in melbourne was powered by a stock RB25. Of course if it had 290 degree cams and a smaller stroke crank with custom rods and pistons it would've been better Link to comment https://www.sau.com.au/forums/topic/379780-how-much-rev-have-people-got-out-of-rb25det-or-rb20det-and-what-mods/#findComment-6056342 Share on other sites More sharing options...
