I have a 2001 LS1. I have the fast 92 intake and throttle body ( not on car yet ) I am thinking of just doing a cam and springs upgrade and a ls6 ported oil pump, ls2 water pump and am curious of the underdrive pullys. Is it worth it and what cam would give me a reliable cam for track and daily driving.
thanks for any advice in advance

check TSP for their cam kit ,cam/springs/push rods.pulley swap is a good idea.what gears,transmission,exhaust system do you have?how many miles on the motor?a 224 cam is good for a A4 stock stall.if you have a M6 the 228 cam is great.more infor,more advice.take your time ,read a lot of threads decide what you want to do.

tranny is a T56, gears are a 3.23 ( 2003 cobra 8.8 )engine has 64K miles, I'm doing gm perf. double roller chain, exhaust will be stanton shorty headers with 2.5 exhaust. Its going in my miata. Also what do you think about the underdrive pullys?? thunms up or down.

I'm about to do pullys. From what I've heard its around 5-10HP.
Not bad if you ask me for $200

SLP is the best-also called the powerbond I believe. You will need new belts,a Chrysler puller and might be a good idea to get the asp resusable crank bolt. Expect a tenth and a MPH on a car like yours

Like the others have stated, if you're doing the cam swap it's worth the $200 for an underdrive pulley. Might squeeze 5 - 10 rwhp out of it and most report gains of a tenth + 1 mph in the quarter.

Since you have a M6 the charging issues should be a non-issue.

I put a powerbond on my old cammed LS6 setup, there was a definite gain. Do yourself a favor and go out and find a piece of threaded rod the same as the crank bolt and make yourself an install tool, I did for like 10$ and it made my life so much easier. No worry about stripped threads.

M16 x 2.0 is the stock thread. I tapped mine out even larger and installed mine with a stud.

Thanks, I couldn't remember the thread off the top of my head. I still have the tool I made, 5 fender washers, a nut, and an acorn nut on top to tighten it in with. Worked like a charm.

putting a V8 in a miata sound great.subframe conectors?

under the car there is the frame rails that run front to back, there is a kit you can get that basically hug the rails and bolt on both sides. Gives it way more rigidity.

Alot of different cams out there, u really need to do your homework. Talk to some vendors they can help....UD pulleys have been show to give a tenth or so at the track. Currently installing mine now.

Powerbond 25% UD (makes the SLP pulley).

I'd really recommend/prefer the Fluidampr, but it's only available in a factory and 10% UD sizes, no 25% UD size.
