The only thing on your list thats SLP I would buy is the underdrive. SLP is way overpriced. You could buy the STS and be done with it. Sounds like you have a big budget! I would go with Trickflow heads, roller rockers, a sweet custom cam, bolt ons and stay N/A.


If you are only choosing from the option listed, I would go with the STS. If you go with the STS now, you can get a forged short block dwn the road and increase your boost and make some realy good power.

[QUOTE=phoenix1987;8383067]SLP is way overpriced.QUOTE]

I agree, however, ive used them in the past and pricey they may be, they all seem to be quality parts. i like the skid plate just for ease of oil change. and i was informed that i would want/need a set of headers with the STS kit, so jack that option up another $1100

i to have used SLP parts and not been happy with them as well for the most part, not much i would really buy from them either. i think there is a turbo kit that bolts to the stock manifolds. Talk to nine ball about turboed gtos he knows

If you are going to do the turbo, why not do a twin turbo setup instead. Im not a big fan of STS although it may be a good product, i just think you would be more satisfied with the twin turbos. Just my $0.02

ToddAlmighty

a local guy here has spoken with me about going twin turbo. the only reason i like the STS is the price... $4500 from Thunder Racing.

man, flawed plans i think. I think you should go with the trick flow heads, vindicator cam, and F2 nitrous pilled for the 200 shot.... BIG power... Good tires, and a good clutch as well... Car would be much faster.. But whatever, your car.

rsodeputy61

What do I think? I think you have a helluva lot more money than me and that fockin sox!!!!

only advice i can give you is the true price of force induction bro. Sure the kit cost 4500 but there are more variables to look at too check out this thread:

https://ls1tech.com/forums/forced-induction/567592-real-price-forced-induction.html

Me personally i would go with H/C/I/Nitrous

Thanks for the input guys, the more i think about it the more i was leaning towards H/C/N combo. turns out the only reason hes been talking so much **** is his dad just bought him a supercharger and some longtubes. granted he knows nothing about the LS engine series. im afraid hes gonna frag the car before i get mine built. i think hes still running the stock clutch (there was no mention of an upgrade, much less a fuel pump). either way, at least now i know what im up against. high 400s-low500s i figure. hes still running the stock catback and stock internals. so im thinkin big cam, decent heads, maybe LSX intake.... then the TNT 100 shot. that should be a race.

silver01z06

a 500rwhp h/c/n car will run harder than a 500 rwhp turbo car, especially a sts car

slp--firehawk

Wow his daddy bought him a supercharger? Im only 19 and that still sounds rediculous... hes gunna kill someone... thats what we said about my friend whos dad bought him a supercharger for the gto his dad also bought him. A year later this guy i know is in a coma forever and the other person is retarded forever, while my friend and his friend walked away with broken bones.... Anyways be SUPER carefull, SERIOUSLY though.

But on the setup... This stuff sounds like a bunch of newbie bs (sorry just bein honest) a blown stock ls1 sounds like it sucks and aint gunna last for crap. Take your engine out, build it taking out all the weak links, pistons, rods, bearings, cam, then turbo or biturbo it as cheap as you can and have it tuned and ull rip the nuts off his vette in every gear for around 8 g's unless you have someone do everything for you, then your lookin at... certainly "more"

nah, my sprayed cam only SS went low 11s.

<-- not a newb

however, ive been looking around on tsps website and im think this looks kinda sexy with some PRC heads and a 233/239, maybe a fast 90/90.

oh yeah, and the TNT wet kit...

ok mr 34 posts... you sound like the newb here. there are many f/i kits made for a stock car. many people on this forum are running sts kits and others on stock internals... and 8gs for a complete engine build and forced induction is crazy. you can do it for that cheap but its gonna fall apart sooner or later...

my vote goes with your basic bolts ons, anyhting from a 226 to a 230 cam and a set of ported ls6 heads, few susp. mods, 150 shot and some et streets and you should be good.... and if u have the money later down the road or if u want to first i would do rear end and tranny work

cartek makes some really quality heads/cam packages as well as an awesome street/strip clutch . also think about working in a moser or a good rear .

do yourself a favor and call tsp... they will hook you up with everything you need bolt on and h/c wise... then call any of the nitrous sponsors and they will send you in the right direction with that

Asmodeus

A bunch of newbie bs is when someone thinks they know everything after taking a "ase certified engine performance and emissions controlls technician" test, and actually knows 2 things about building an LS1; Jack and Crap.. Sorry.. just being honest.

as far as nitrous, ive had AMAZING results with TNTs F1 kit in the past. for me this is a no question mod. i will be using a tnt f1 kit.
