lmao...you are wrong. a stock block with correct tuning will handle 250whp. a vitara built block on stock sleeves will handle 350+ no problem what so ever. hell, the stock sleeves will hold 600whp, its already been done250 HP ??? That's going to be hard to acheive, with the stock motor, even fully built turbo...I'd swap it for a dual cam LS/Vtec or B20Vtec, and turbo it, and you could easly hit your 250 HP mark...or if you're a baller, go with a k20 set up...K20A, I/H/E, K-Pro = 220 WHP alone...Which either way you decide to go, goodluck on your build...
once again...your very wrong. d series motors hold torque better than b series motors. if you wanna have a b series vs d series argument and look stupid feel free to pm me. im good friends with 2 of the best single cam tuners in the united statesI am not going to get into a pissing contest, with you over some BS...I know a 250 hp D-series in acheiveable...But look at the GAY torque numbers that he will have...I was just saying that it would be way easier to acheive his 250 hp, with a B-series turbo, and he'd have higher torque numbers...
get off the band wagon. you obviously dont know what your talking about fan boy
