We will not be making that for 2 reasons.

1. The stick throttle body is huge and no power gains woul be found by increasingthe sizebeyond that.

2. The electronics in the stock TB cannot be swapped over to another unit.
Basically if we were to make that it would be about $750 for something that shows no increase in power.

So I asked about port and polish

And he said "I would not touch the stock TB on that!
Doing so would just open the door to problems and exense with no gains in power.

The old 78mm dbw BBk throttle body's are nothing but problems! If I had a nickel for all the "help! reduced engine power mode with bbk t-body" Threads...I would have a Fast lsxrt!

 

08 TB is already at 90mm measured it today!
