rayaapp2 Posted August 21, 2009 Share Posted August 21, 2009 I have a stock RB25. Maf and all... lol Peak power is suppose to be made at 6800rpm I had a spark plug miss fire at 5000rpm and still put down 252hp and 233 ft/lbs My AFR was a bit to lean as well. Thats a very reasonable number for a stock 26. Congrats Quote Link to comment Share on other sites More sharing options...
Careless Posted August 21, 2009 Share Posted August 21, 2009 the rb26 is extremely underrated, thats part of the reason i went with this engine. it was either an rb26, vq35, or ls1. the rb26 still dominates all in stock form...its a noisey engine but gets the job done.. not sure how the rb26 dominates the LS1 in stock form. But hey, I like them better anyway. Quote Link to comment Share on other sites More sharing options...
kramerbuccs24 Posted September 17, 2009 Share Posted September 17, 2009 these are fantastic numbers!! keep us posted with mods, please Quote Link to comment Share on other sites More sharing options...
240zdan Posted September 18, 2009 Author Share Posted September 18, 2009 mods are 12 psi.. feels alot faster. im going to turn it up to 15 psi pretty soon. after that its a set of gt2860s most likely with a tomei oil pump and apexi power fc or AEM (havent decided) and a good clutch. The 240z will not need any more power after that for a street driven car. Quote Link to comment Share on other sites More sharing options...
