yeah, i know use the search button. there is so much outdated, contradicted, or wrong info its hard to sift through. car in sig. 00 ta m6, i know the usual stuff: lt's, cat back, lid, bit i'm needin to know internals. ws6 store has this: http://www.ws6project.com/user_stor/...14f37eab63a78b, would it get me there? do i want to go with a 59cc on a stock (and extremely low mile) bottom end and run on pump gas? i will see no track time, only street use. prolly 500-1000 miles a year tops. i don't see the reason to run afr's and stainless lt's on a car i won't hardly drive. it's a lot of money to spend on an already expensive car. btw, going to use stock rear and gears, stronger clutch, underdrive pulley, either fast 90/90 or ls6, depending on advice given, open to all ideas except more cubes, and FI. also, will stock injectors be up to the task of my goal? thanks for the help.

ok, maybe i should look at 400 rwhp +/-, i didn't factor in the driveline loss...oops!

Just get a head cam package from TSP, you will need headers, at least a LS6 intake and a tune to get the MOST out of it, look to spend about about $3500 if you do the work yourself. That will put you at about 425+ dynojet

I dont know your budget but a FAST 90 is an awesome product but there is usually a $600 or $700 difference between that and an LS6 intake and you could use that for some good ceramic coated headers. Port the throttle body, a good duration cam, maybe MS3 cam, a set of ported LS6 heads wont run expensive at all, tru dual exhaust for $425. I wouldn't even bother with that UD pulley right now if money is a concern, save it for those $5 gas prices. I think that will definitley get you 400+ whp with a manual on a dynojet...

You always have to option to run 100-125 shot and keep the car stock otherwise. A complete (good) nitrous set-up is about ~$800

My setup will get you there. Check my cardomain page for a full mod list.

Just make sure your cam is proportional to the heads you get.

any mild cam and heads should get u about 425 mark with all bolt ons and good tuning!

i am staying away from the spray, it runs out. all motor seems to be my best bet, however more expensive.

wheelman ws6, i love the way your car sounds with that cam. what is your power band? i prolly wont run past the factory rev limit.

WheelmanWS6

Thanks bud.

Here is the thread with my dyno sheet after the heads/cam install and tune.

https://ls1tech.com/forums/showthrea...552&highlight=

As you can see, the powerband is good until 6500 RPM, when it starts to drop off. If I add a FAST 92/92 setup in the future, I'm pretty sure that the motor will make power all the way to 6700-6800 RPM. But on my stock (LS6) intake, I feel it did pretty well. You would probably wanna bump ur rev limiter up to about 6500 with the F13 just because you still have potential for some power growth after stock redline.

Good luck

honestly if you only drive it that much i would just run a nitrous setup. Nitrous is not as deadly as everyone says it is for your car.

Lucky to see 400rwhp with that package.

rockers are a waste of cash in that set up.

Stock injectors run out around 400rwhp, N/A.

Mods in sig 432rwhp/403rwtq.

May also need to flycut your pistons with the 59cc heads. I do not know, but I would check into it before I ordered the heads if I were you.

my mods in my sig got me 452/395....fwiw

Why 59cc heads? I am planning on making the hp you are talking. Im doing it with a mild custom cam, TSP stage 2.5 5.3 heads(62cc), ARH headers, UD pulley a FAST 92/92 and all the good parts to go with it(Racetronix fuel system, ported oil pump, new LS7 lifters, hardened pushrods ect.) If I hit my goal I will be at 450 rwhp and I may or may not spray a 100hp or 125hp nitrous shot.

Your goals are easily done...Id start with a TSP head and cam kit with the stage 2.5 5.3s and a 228R. Be sure to get the oil pump and all the stuff you really need. Do your research and find the best prices, ask sponsors, an ddo the work yourself. Get a good tune and you will have ~430rwhp in a really drivable car.PM me if you want any info on my setup, id be happy to share info.

i don't want to fly cut, so i'll def check that out. i really appreciate all the info that is being spilled out here. i didn't know i had all of these options. i still think i'll stay all motor. nothing against the n20 guys, that's just not my style i guess...
