What kind of turbo's are on the twin turbo corvettes? Did these cars use L98's? How much HP did they have? Just curious. Maybe I have an idea and maybe I will give someone else one.

Im not sure what turbos they had on them, but they did use L98 engines. I think the top HP they made was close to 400 HP (last year of production).

Go to callaways site and find out...

I was there and looking at the for sale cars that is why I thought it was a L98. Would have been neat for them to build turbo camaros or Turbo GTA's.

according to a mag of mine from 1991 that just started to fall apart in my hand: 403HP@4500RPM, 575TQ@3000
0-60: 4.4 sec

for an extra $6000 there was a 450HP version with 613TQ at the same RPMs

oh sweet. a 454 C-4 labled the ZR2 is in here too

Was the zr2 a test car that never got made? I never heard of it, but until a couple of years ago I never heard of a zr1 now I know a little about it. Would those turbo's and exhaust manifolds bolt onto a 305? Or would the entire engine swap be more worth while?

the zr2 is a 4 wheel drive s-10 right. I don't know if i would want all that power in a pickup.

um you are confused. zr2 was a designation from old(early 70's) big block Singray Corvettes. ZR1 was the designation for some old(70's) small block singray corvette. The ZR1 was brought back around 1990. GM did a concept car ZR2 to 'rouse intrest in the time around when the ZR1 was out but didn't get very far. Later they gave up and put the badge on the 4x4 s10.

Yes they would bolt up. But the trick here is would a pair of turbos bolt onto those manifolds in a 3rd gen?

A rule of thumb good to go by. Turbo systems are designed for cars, not for motors.

hey guys, the 88 callaway sledgehammer vette ran a twin turbo forged internal and i believe 383 cid L98 based engine that produced 880 HP @6250 RPM, capable of 3.9 sec 0-60, and the amazing top speed of 254.7mph, with a then experimental, and no less impressive 6 spd. at the etime they approximated 400 grand to duplicate it, but figure on about half to a quarteer tat for parts and installation, unless you know what youre doing, for an f body. and id assume that with a deeper gear itd run the quarter a lot faster. my dream car though...
