Anybody install a larger throttle body on their Z/G. I was looking at the Top Secret 100mm larger throttle body found here:

http://www.topsecretjpn.com/engine.shtml

Anyone know what kind of gains (if any) this would provide. Would tuning be required? Is it even worth it?

 

$1131 for a throttlebody?????

 

lol. I kno--expensive. Look at the individual throttle body package though (over 6k+)

 

yea, not worth a grand for a probably small increase in power/torque. and id run the itb's if i was n/a.

 

Problem with this Throttle body is that it is NOT drive by wire. You would have to connect a cable insted of plugging it into the drive by wire system.

And you would need some sort of engine management to make it work.

I had mine bored out by Proflow designs. Didn't make that much difference.

Exactly. For the cost just go accufab and go with a throttle cable like we had to do for racing.

Has anyone tried out a GM LS7 throttle body yet? They are DBW, but I would assume you would need an EMS to configure the TPS.

 

Nope, but i would be willing to give it a go.

Anymore info on this? How much are they?

Let me know
Todd

 

Sounds interesting I will be willing to try that out. Thanks for the heads up.

 

The LS7 throttle body with the motor go on eBay for $305 buy it now. They are 90mm I believe. Accufab for a 90mm retail for $280ish.
