My conversion is nearing completion. Swap is not very difficult and WILL I repeat WILL fit under the stock hood without modifications. Shoot me an e-mail because I have learned pretty much about the rb26 with all of the research I have done to do my swap, For the power level$ you want your gonna spend big bucks and have plenty of wait time. Took 3 months for my power fc d-jetro kit. Don't forget to upgrade the oil pump, that is your #1 best friend right there. dsmcvc@aol.com... good luck
