I’m kind of kicking myself because when my friend replaced his intake manifold with an aluminum one he offered to sell me the one that came off of his car for 20 bux and I didn’t take it. It was off of a 02 SS with all the bells and whistles from the factory. So I think that this was an LS6 manifold correct??? Now I see these things sell on ebay for big bux.

I want to build a 400 - 450 RWHP LS1 for a project vehicle of mine. I want to accomplish this by doing a semi aggressive cam and some cheap heads, like maybe the heads edlebrock is suppose to come out with. I also will have decent mid tube headers and an X pipe true dual exhaust system. Will this alone be enough for my goal or do I need get a new MAF, TB, and intake manifold? The engine is from a 99 Trans Am.

for the upper end of the spectrum you'll need at least the TB and intake, stock MAF is fine.

all 01+ cars have the ls6 intake regardless of trim. and yes your a dumbass for not taking it

What happens if he doesnt do the LS6 intake swap? Will he really lose that much power?

just depends. On a HC motor depending on how mild or wild he could be down 15-20 or so. Some motors are down more some are down less just depends.

ls6 intake, TB, and pulley are worth alot more on a h/c combo, big or small, then some people realize.

Damn....... I’m really mad I didn’t make that deal, oh well that was years ago any way.

Keep in mind that im looking for 400-425RWHP and nothing more. The engine is going in a car that weighs 2300lbs and I don’t want more than 425RWHP because of traction variables. I feel like sometimes people give advice to get the most out of a certain set up, and that isn’t what I am looking for in this case. So will I need Heads, Cam, TB, Pulley, and manifold to reach 425rwhp or will that set up most likely result in more HP?

forget all that, what you need is a fuel pump and a TNT 125 shot

Is it gonna be an A4 or M6? It takes more mods to get the #s in an A4, although it may actually be quicker down the track with the proper converter. For example, my car only put down 363rwhp through the converter, but it ran high 11's in poor weather conditions. That HP seems low, but the track times speak for themselves. The car probably has 11.80s or better in it N/A with the right conditions, although I may never know due to I have a new cam in mind before this seasons up and going MS3

well why didnt you state that in the first place. and in your first post you said 400-450rwhp not 400-425rwhp.

if its going in a 2300lbs car just keep it stock. 350, 400, or 425rwhp your gonna have traction issues. dont kid yourself in thinking that 400rwhp is a "safe" number.

I guess the fist hp quote was a typo as I had 425 in my head the all along. I have seen these cars with LS1 with the power I stated and they can be configured to hook up decently, however anything past that and your looking at broken rear ends and no traction. Forget the traction issues with the car, lets pretend we are talking about only the engine. Do you have an answer to my question?

yes. provided its an m6 just about any head + 224* or bigger cam and key bolt ons should net you your goal. tuned of course.

or you can do it cam only with large cam and stock heads. it all depends on the type of powerband and application your looking for.

I'll bite ..... what car? What application?
