Default Differance between L1 and LS2 Throttle Body

Title said it all, I'm looking for a cable driven throttle body for my LS2 powered panoz track car and wondered if an LS1 throttle body would work on and LS2 stock intake? Are they the same bore diameter and flow the same?

For a stock LS2 intake you need a 4 bolt TB, 90mm or larger.

LS1 v LS2 stock intake.


Holley 90mm


FAST or Nick Williams etc also

Thanks, I'm just getting into the LS engine details, and discovering I have a lot to learn. But got to learn, as I have an LS2 long block, and a bunch of parts I'm picking up off the forum so I can install it in my PAnoz track car and replace the weak sbf 302.

Thanks again

Default Panoz pictures

Yes I do, but I'm new to this forum, how do you insert a picture into the thread?
We did a track event art Daytona last week, we did the oval and the infield road course. The oval is just nuts thinking about what could happen if you cut a tire, those wall are RIGHT THERE !!! With no time to do anything.
Any way, can you help with posting pictues?
