Best Bang for Buck Intake Manifold for LS1?

**GottaHaveLS1** · 04-12-2011, 08:49 AM

I'm thinking about swapping out my stock ls1 intake manifold for a better flowing one. I don't want to break the bank on this one because my motor/heads are stock and I figure I'd get an expensive 92mm intake manifold when I do a head/cam swap (years from now). Which intake do you think would be best going with? It seems a decent improvement can be found with the stock ls6 intake, do you think it's worth it? Also, I've seen a lot of used intake manifolds for sale.. can't imagine anything wrong with them, they just must have been swapped out. Anything wrong with getting a used one?

Let me know what you guys think. I'm going to get my TB P&P too, so hopefully this will net me a 15 HP gain.

Thanks in advance fellas!

Alot of people get a used ls6 and it's worth it. With a new TB, it'll be a noticable improvment.

How aggressive do you plan on going with the heads and cam?

Agreed. Find a used LS6 intake and be done.

Hell, even with a mild cam, the LS6 intake would be fine.

I agree.

If he is planning on making it a mainly track car, then I'd recommend the fast 102.

I've never taken my car to the track.. would love to some day though. She's a street car. I haven't looked much into head and cam swaps because I can't afford it yet but I would still want something streetable with approx 400 rwhp. I figured I'd get a cheap intake for now and when i do the h/c swap in a few years i'd go with 92 mm tb and intake. seems like the used ls6 is the best way to go for now.

I have some mechanical experience with cars and wouldn't mind saving some $ by installing it myself. What do you guys think?

It's easy one day project you can do in the garage.

I've done it last Sep and I even stepped up and painted mine.

For me the LS6 was an easy choice. Even with the mild cam I am running.

I liked the stock appearance for starters, they are cheap enough, everything bolts right back on too.

I've seen some very quick 4th gens with LS6 intakes. But for what I do with ours, (wifes daily driver, 99% street car along with vacation trips) I figured the LS6 would suit me fine.

If I were looking for an all out performance car that was a weekend toy and it spent alot of time at the track, then I'd spring for the FAST setup hands down. But that's just overkill for me at this point.
