Wow the ka24e T in action speaks volumes for the power increase to be had.
Thats not the site, I believe I found a site where the price was $2,599 for the S13 1989 240sx turbo kit.
I have this saved page on my hard drive
http://www.geocities.com/sxt240/SOHCmanifold.html
But the site died and THATS not the page either.
ARGh this sucks.
Thank you Chuck for that awesome link, I'll be drooling over that video for some time now.
