Fellas need your help I don't know whether to get the VTEC engine or non-vtec engine for the use of a turbocharged vehicle. I hear of a lot of people turning the VTEC off when they go turbo? So why all the VTEC craze? From my understanding the VTEC motors favor a style of quicker inhaling and exhaling, which is more favorable for all motor cars who need to shift @ 9 and 10g. Now for turbocharged vehicles you don't need to rev that high. I say 8g at the most. What good can the VTEC mechanism do for a turbocharged vehicle is probably a better question? Most turbo cars need longer gears which are not a characteristic of many of the VTEC motors most of them have a 4.4FDR. If I do go turbo and use a VTEC motor it will be the H22 92-96 block preferably. It has some of the longes gears even longer than an LS motor both have 4.2FDR but the H22 is somewhat lower. So please help me out!!

 

A GSR motor will beat an LS motor with the same mods and tuning.

I prefer to stick with the LS because it's cheaper.

 

VTEC heads and intake manifolds flow more than their non- VTEC counterparts. Use adjustable cam gears to dial out the overlap and you'll have a killer setup. But for us boosted SOHC VTEC guys, it's a little more difficult...

 

i seconed that.
