Yep, actually she only good to handle 500-550 relalable whp, like all RB26's, unless internal are upgraded. My orginal motor is 1 of 98, it was still replace for a stock r34 N1. Just let me know otherwise I'll source out another block from japan to build.LOL another spare? she is 1 of 250 I can't have her laying around...plus it is strong enough to handle what you want so it shouldnt be a share. That means I got over 7 people on this engine alot. And this is the only day it has been officially known on the boards that it will be sold...but I will let everyone know when she is out. Who wants it the most can have it I dont care. If it was a standard RB I wouldnt care to let anyone take it off my hands for free they would just have to pay for shipping and handling.
