GSR W/ FI vs. LS W/

[PSU-TEG]

All other things (mods) being equal.... How big of a difference would a GSR with forced induction make over a LS with forced induction. (or even difference in potential) I have heard that a Vtec engine will not make that big of a difference in forced induction engines. The reason I ask is becuase I am about to swap in a GSR engine into my '99 LS. And down the road I am planing on going with FI (not sure if turbo or super, but that is besides the point). I am wondering if spending the $3000+ on the GSR would be worth it if I am going FI later. Would the GSR FI yeild that much more HP that a LS FI?? Does the GSR FI allow for that much greater potential than LS FI. Or if I am planing on FI, should I keep the LS and us that engine for FI. Lets compare the to engines for Supercharging for arguments sake. Because if it would be better to keep the LS, I will probably supercharge it soon, buecase I could spend the $3000+ that I have on that now.

Keep in mind, I am thinking of this car as a daily driver project. I want to know which would be better and yeild the most gains down the road as a long term project. I'm not just looking for the most power for my buck as soon as possible. But yet, I don't want to spend $3000+ for the GSR if it is only going to give me a difference of 10-15 extra horsepower in the long run. I don't think that would be worth it.

Suggestions?? Advice??

Have you had a look at the post (turbo integra videos), The guy Direp or something and his buddy own a ls turbo and a gsr turbo, I think all your answers will be in that post . IMO from only what I 've heard not worth the effort or money the LS is a great motor to turbo. Check out that post.
