I just wanted to see what the gains are going from an ls6 intake to a 90/90 setup, been thinking baout going to a 90/90 for a couple of months now. I know a lot of people think its too big and a waste of money, im trying to go as fast as i can with stock internals so camming my car isnt an option. Dyno numbers or track times of gains are much appreciated

The fast works great if you have a good H/C combo that out flows the LS6 intake. But if you just have bolt ons it's not worth it:

i forgot to mention my mod list, i will have 243 ls6 heads, but i still will have the stockc am in it. My other mods are longtubes, tsp true duals, upd, lid, 342's and a 3800 stall.

i know i know, a lot of you will say well thats not a stock ls1, your right but it is oem, Im not going for any records here so im not looking for a specific title. I just want to be able to say i have a "stock" engine

Your probably going to see minimal if any gain on stock cube motor with stock heads(using the 90/90 combo) an LS6 and ported TB and the 243 LS6 heads will do just as well on your application.

My crate LS6/full bolt-ons/90.90/9''/M6 Dyno'd 405rwhp and 383rwtq. So pretty much the same thing you have but 9''/M6/and the LS6 cam which isn't too much bigger than a stock Ls1 cam. I wouldn't expect too much of a gain with the 90/90 without a cam but if you ever think you might change your mind in the future and even go with a baby cam like a 228R or something then it would be a good buy if you can get a good deal.

thats what im thinking as well. if i gain 5-10rwhp from it thats fine, right now its a max effort 346, and those numbers arent bad at all, i would take 405rwhp in a heart beat

Did you buy the 243's yet? I wish I had gone with a stage I cnc ported 243. They really aren't too much more expensive.

Any reason why you are doing heads and leaving the cam alone? A small cam like my TR224 is so much better than the stock cam.

i want the motor to be "stock" Im going for a sleeper kind of deal i guess

That's cool, everybody has their own plan. Personally I found swapping the heads to be a lot of work - I did it all by myself. And if you're going to go through all that work it would be nice to have some good performance results.

If you're goin for a sleeper feel have you thought about the cheatr cam?

plaf713

yeah ive looked into it, the thing is that i can get a cam or i can get 243s, if im going to cam my car then i would want to do everything like timing chain, ls6 oil pump, pushrods, valve springs, cam, most sets with everything included is more than stock 243 heads, im sure eventually i will do a cam but not in the near future.

And to mass, ive done both head swaps and cam swaps and i feel that head swaps are easier, just my opinion though

eamador11

I agree, your putting in more air than the cam can let in anyway so its a waste. do h/c first

Definately working backwards...
Stall,Cam,Heads in the A4.. i that Order... Try to match them... I would consider my car "stock"...with tastefull bolt on's..

G5X3 cam, unported 243's, Vig 3600 stall, stock cub'd 346, bolt on's..
Dynoed @ 403/405 to the wheels... not too shabby for an Auto...

ive stalled it already, i dont want to do a cam simply because its def not "stock" anymore, i'd like to travel the road less traveled.

haha... you car is FAR from stock

youll be fine with the 90/90... you can just "grow into it".

i also plan on dynotuning the car after the heads and the 90/90 go on, i think ill have goodluck witht hem. Hoping to trap somewhere around 114-115

i just dont see the 1k for it is worth it over the ls6 if you dont plan on doing H/C

How bout a ported LS2 intake and TB, Im sure that would be cheaper than a fast setup. Might net you similar gains.

first off i dont think it will be 1k, i already have the throttle body. I have found 90 intakes going for 600-650, i'll buy that and then sell my ls6 intake for 300, then we are only talking 300-350 bucks, sounds like a good deal to me
