Take a piece of round stock and cut it down to the diameter of the new throttle body bore, for an inch or two. Take the round stock to a mill and cut a 7* angle in the end. ==\ Kinda like that. Layout, drill and tap two holes in the same location as the holes in the throttle bodies shaft, the holes that will hold the plate to the shaft. Bolt a piece of brass plate to the end of the jig you just made and put the jig back in the lathe. Turn the plate down to the diameter of the jig without cutting into the jig itself. Profit. Now, if only I could access get access to a machine shop.

Toni won't even return my logs to me anymore after I scheduled time on his stupid calendar.

"Oh I'll be busy tuning local cars today so responses may be delayed"

Never one email back after that one. Customer service went to shit as well as their parts. Glad I didn't get anything but a tune.

I've asked this same question myself, as a 68mm TB will flow enough air to support well over 300 HP. What is the size of the MAF anyway? If it's any smaller than the TB a bigger TB isn't going to really help. Unless your going big boost I really can't see the point. But it ain't my money...

Stock MAF housing is 2.5" (63.5mm) IIRC.

I know of one!

There was another vendor working on an oversized throttle body. They spent considerable time on it and couldn't make the car run smooth... Even using ecutek. If Toni managed to find the secret, while destroying engines and burning all ft86 bridges, I would be very surprised.

whoa I didn't realize all this stuff happened with that guy. I've been away from here for a few months lol, I almost went to his shop to see about getting work. glad I found another place that is awesome.

What has happened to the posts from the pioneering member from NY, who supposedly ordered the FA20Club throttle body?

I guess he still remains a mistery :0
