bored throttle body

[MATT91GT]

i have a spare throttle body and intake manifold and i have friends in machining classes. i was thinking of giving them to my friend to bore. If i had him bore my throttle body what is the most i should have it bored to?

I believe its 7mm over stock is the max. your friend is best to measure the port opening on the intake manifold and then measure the lower inside lip...since that will be the first section to run out of material the quickest.

If it turns out good, I send you TB and some cash?

no problem, but you know the lower inside lip i'm talking about tho right? that'll be the first spot to run out of room.

yea i look at the inside earlier and noticed that

so when will you hear back from your friend? i'm sure if he's able to do this, a few ppl might want in on this. Probably doesn't cost a lot either.

well he wont start machining classes until january. but its an idea i have floating around in my head.
