if your going to do heads and cam definetly get the LSX if your just gunna do bolt ons then ls6. i saw a 18+Hp gain from my LSX. and im a Cam only car. no heads. and this was a 78mm. if you going to be doing a lot of power i would say get the 90mm and 90mm TB. but if not.. get your Stock one ported and put on the 78mm LSX i would say from a stock ported TB and 78mm LSX you will see 25+ RWHP thats just my .02

I will be doing EVERYTHING possible....eventually....but i have 3 yrs left on my warranty.....so i cant do the heads and cams so would the 90mm lsx and tb be ok, until i can get heads and a cam?

FWIW, the $$$ amount of the LSX over the Ls6 isn't worth 1hp and 5lbs of tq. From experience, two people i know who have got them had fit problems. One had severe misfiring due to a manifold leak affecting a few cylinders. Also, they are made out of plastic instead of composit material.

is his car is an ls1 manifold... going from an ls1 manifold to LSX you will see a dramatic gain. i saw 18+ horses from mine. which i was very happy with. i might be doing heads sooner or later but im just sticking wit the 78mm. if i were you i would buy the 78 and then later on when i get heads and Cam just get the 78mm one Ported. thats my .02

I was asking a similar thing a few days ago-based on the various responses and people's personal experiences... For my HP/TQ goals, the extra cost of the LSX over the LS6 intake is NOT justified. then again, I'm only looking to put down about 420HP/400TQ N/A when my project is done. you're probably looking at a much higher goal and might need the extra numbers the LSX has over the LS6.

Yeah, CHP has been doing a bunch of dyno tests recently on LS1s and the LSX is only giving around 3-8 HP/ 3-4 TQ on an engine dyno over the LS6... not worth almost $800 IMHO.

The good part about the LS6 intake is we sell them for $360. That's alot less $$$ than the LSx.
As far as hp differences, we've seen a additional 8rwhp with the LSX on a cam only car...
You could always buy a ls6 & sell it when you upgrade... I really think a used ls6 intake sells for $300, so you could always sell it if you decided to go with with the lsx.
It's a hard call between the two...
