Which engine is best suited for turbocharging taking into consideration things like compression, tranny gearing,stock bottom end.Is the Vtech a better choice for it's VTECH and extra block lubing capabilities.I've also heard that the LS trannies gearing is better for turbo.I want to hear from some experienced FI people please.Thanks

 

I'm not experienced but I've ALWAYS heard that LS is better for turbo mainly because the fact of lower compression ratio.

 

GSR
To do it right you are going to have to pull the engine apart and do some internal work anyway... replacing the pistons in the GSR would eliminate the LS's only advatange (aside from the slightly marger displacement).

Better yet... b16a2 or 3. better rod/stroke ratio

 

VTECH....hahahahahahahahaahahahahahahahhaahaha ok I'm done now.

Anyway, LS, GSR......It's a freakin long *** debate. And please do not respond just cause you heard from some guy who said so. Also do not respond if you cant back your **** up. Use the search function. They have detailed explanations that I wouldn't want to type. Can we please move this to the newbie questions.....

 

if you can afford the extra price for a GSR, might as well get that and turbo it!

It's always better to start modding a better car.. rather than modding a inferior one.

That and if you really up the boost u will have to tear apart the engine anyways!

 

VTECH?? isnt that a phone???

Will-

 

LS isn't better for lower compression, it's better for longer stroke. In Either motor you're probably going to install low compression forged pistons for FI. In turbo applications it's common to lose power at the vtec crossover. So for those reasons I'd have to say an LS would be a better bet for turbo
