Need some suggestions!
Need some suggestions! Ok i am building a 99 trans am, i have completed the suspension, brakes, body work, interior and transmission, tires and wheels all of which is new, Instead of dumping money into a 155,000 mile 99 ls1 engine I am currently getting a new stock GM crate ls1 installed as we speak, I have a good exhaust, ls6 intake, good wires and a bigger lid. I was wanting to get a little extra RELIABLE power out of it without spending a whole lot more money or going into the motor if at all possible, My goal is about 400-420hp, is there any way to achieve that with just bolt ons, and keeping it N/A?
Thanks
Thanks
$3400, yeah its the 2004 version of the ls1.
im talking about external engine... not messing with the internals, its my daily driver, just a nice street car, also the engine has a 100,000 mile warranty so im just looking for bolt ons

That is a whole lot of money for a stock ls1. You could have got a brand new forged 347 for that or just a tad more for a 383
Fast intake and throttle body
1 7/8 headers with a flowmaster merge 4" I pipe cutout reduced down to 3" choice of muffler
Chrs1313 RAM air
Larger lid and maf
Electric water pump
Underdrive pulley
Technically heads are not internal like a cam... If you can do heads without a warranty I would do some afr 205s with some rockers
That should get you very close to tor goal and make a nasty bolt on car, or bolt on with heads.

Cam should be one of your first/next mods. If you aren't willing to go inside the engine then don't chase 400+hp goals.....The reason I say that is because there is a lot of money to be wasted for someone else to come along who spent a fraction of what you did and have a faster/funner car then you do.

im not willing to go inside of the motor, i am asking about bolt on power adders, if i go into the motor I will void the warranty which is ignorant to me, but yes I agree a cam would be a good thing to look into, but after i hit 100,000.. it is my daily driver, i no die hard drag racer, i go to our local track and all but really I just like blowing ricers away and ****.
Whayy exactly is a underdrive pulley? i have always wondered that
also what is Chrs1313 RAM air? ive got the oem ram air, and a mti lid, but im looking for a slp lid and bigger maf.
also I had a diablo sport tune on my old motor, what is y'alls position on diablos tune? and would i get better power if i took it to get dyno tuned, i live in thibodaux la now but near were i used to live there is a place called hennesy that does dyno tuning.
also how much quicker would it be if i put 4.10's in it, i know it doesnt add hp, but would it make a difference in quickness? i have 3.42s
thanks in advance

Speed Inc. sells them on their site. It is just an aftermarket ram air, best on the market actually.
Don't do a Diablo, get a dyno tune.
410s would make a big difference for a manual. Unless your going to a larger diameter lid, I wouldn't worry about switching unless you just like SLPs lid better. They all make the same power.
It is the very bottom center of the motor (the large pulley that you can see). Most do it when they do a cam, but you can do it any time. It is good for 4-9HP or so.

yeah i know exactly what your talking about, i always just called it a harmonic balancer, or crank pulley, just another term for it. I had to take it off to put a new oil pump in my old motor.
so is the chrs1313 like the slp cold air kit? were it directs the air into the airbox?
so i would achieve some quickness from dropping to 4.10's? because i have a leaking pinion seal (go figure) and i was going to replace that anyways, plus the rear end has a small ammount of slack in it.
basically i am asking if dropping to 4.10's would be worth the money? i have a pretty BA t56. pro 5.0 and better forks and all the goodies...supposed to be built for 900hp.

Never bought a crate engine myself, but... am I to understand that one can slap on any combination of radical bolt-ons in the whole wide world but the minute you put a cam in, *then* GMPP turns it's back on you?

The Chrs1313 is similar to the other ram airs, like the SLP... But it is superior. It has proven to pick up nearly 1 mph over the other ram airs. If you buy one, get the Chrs1313.
thanks lemons you have been helpful, im running a factory 2006 z06 clutch, my trans is on point.
I spoke with my buddy at the local gm dealer and he said as long as its N/A and nothing is changed in the internals it should stay in warranty. hope he is correct
