351Windsor,
I see that this is your first post, so welcome to LS1Tech.com!

Your post really belongs over here https://ls1tech.com/forums/conversions-swaps-28/ for conversions. You might want to read the sticky at the top about the purpose of this forum https://ls1tech.com/forums/advanced-engineering-tech/396223-what-forum-please-read-before-posting.html.

In general, I'd recommend some good CNC'd heads and a mildly bigger cam (something like a 218/224 114) initially and a good tune. Then some decent headers and maybe a lower restriction intake later to spread out the cost.

Once again, welcome.

Steve

Probably gonna get booted from the advanced section for sure. Although I'm gonna follow to see more pics hehe . Check the stickys in the New LS1 owners and introduction and Gen III internals sections. Then ask some more specific questions around the site.

Wow sick looking car! As for performance if you dont want a big lumpy cam in there and want 100 extra horses to the rear wheels id look into a tr 224 cam (with comp 918 spings, hardened pushrods, titanium retainers) and some afr 205 heads, 25% underdrive pulley, ported TB, custom lt headers, and custom duals. That should net you around 400+ rwhp, which would be 100 rwhp over stock. You could also go FI and run a procharger ps1c/d1sc at 7 psi, with an ls6 cam and comp 918 springs, and be pushing close to 500 rwhp. Would you prefer staying NA or going FI?

Im a stalled A4 and put down 417rwhp 407rwt with a pretty small cam,and here is my set up(mods)
MTI lid
Slp maf
Nick williams 90mm TB
Ported fast intake(port work by vengeance)
Texas speed and performance heads stage 2.5 5.3L heads
Thunder Racing 224/112 cam
Hedman Lt hedders
42lb inj
TCI ssf 3500stall
RPM level4 4l60e trans
Dyno mouth exhaust(SLP loudmouth w/Dynomax bullit)
ractronix fuel pump
Thats it as far as horsepower goes Iknow the numbers seem low,but dont have apulley or electric water pump,and its a stalled A4 so it wont dyno as high.Its a very streetable combo
hope this helps you out

Honestly that's the kit car I want to buy in a few years, and put a built turboed s1 in it and just destroy everything. And look damn good doing it

If you can get a hold of a vette LS2 motor, have it built with a 4 inch crank (402 cubes). Then get some trick flow canted valve heads, a custom cam (specced to what you want.. smooth sound/aggressive sound/powerband.. etc), and a ported FAST 90mm intake/ TB for the top end. You definately want to do long tubes, an x-pipe and dual exhaust. Some vettes sound downright exotic and it would really match the looks on that car. That combo depending on cam selection should make 500-550 rwhp all day.

If you are stuck with stock cubes and an LS1 motor, put the same top end package on it. Check out the dyno section as well. A 346 cubic inch motor with that top end package should put down 450-480 rwhp depending on cam selection.
