GSR head intake port has a straighter shot angle into the combustion chamber than the Del Sol head. Stock wise, the GSR port volume is larger. Yes the 1994 and newer Del Sol engine was the B16A. Before 1994, the Del Sol had the D16Z6 SOHC VTEC head. Port the B16A head and it will be the better of the 2. If you don't plan to port then, the GSR is the better of the 2 for an LSVTEC's rod ratio and powerband location needs. And if you spell VTEC like that again, I'll stop answering any more questions from you and consider you prime a candidate for promotion to become Uncle Ben's newest nephew.Kiss_Mai_HatCh on Aug/22/02 said:Are all vtech heads the same cause i have a grs and delsol vtec head (is this the same as a b16 ?) witch head will give more hp or will that come from the part of it is put together. Should this be another topic?
Well, VTEC actually stands for Variable Valve Timing Lift and Electronic Control (switch your Timing and your And) and then it would be perfect, but hey, who's being nitpicky...Fentoozler45 on Aug/23/02VTECH = [img said:http://www.imagestation.com/picture/sraid28/p3a33e792b2de846c3229948fc6272707/fd6b8680.jpg[/img]]
VTEC = Variable Valve Timing and Lift Electronic Control
Saying your Honda/Acura has VTECH will get you more noogies and titty twisters than you can stand.
