RB vs SR question for A31

trgft · May 14th, 2009, 02:53 AM

hi all,
Ive searched the forum and I knew this have been disscussed many time. but for my car (93 Nissan Cefiro A31), it seems like a different case.

Im building a 92 A31(car not in US) for time attack and some drifting. It came with RB24 engine. currently I have the car fully disassembly and getting chasis reinforcement, and tring to make a decision between SR20det and rb25det.

what do you recommend?

thanks in advance!

i don,t know much about rb25's but i know the sr is lighter,it's an aluminum block with sleeved cylinders and can handle jsut as much boost 40-45 less hp but the weight difference makes up for it,

I don't know much about drifting but I do know the added toque of the rb over the sr is huge. High revs and fast spool are big fundimentals for my daily driving needs. On the track.. I don't have much of a valuable opinion.
