52 mm or 58 throttle body lt1?
I have a stock 52 mm intake would it hurt if I know I want to go 58 in the future and I just buy the 58 now and wind up porting to a 58 later. Would putting a 58 take away from the torque. What is the difference or am I just better off just buying a 52 for now.

I cant comment on how a 58mm TB does COMPARED to a 52mm, but on my TPI motor I noticed a nice gain when I went to 58mm (with ported upper plenum to match).
Personally, I would get a 58mm NOW if you plan to do ANYTHING more in the future. You won't lose anything by using a 58mm over a 52mm. If you plan to spray, boost, or go big bore N/A, you'll be set in that department at least.
You'll want to bore out the intake from it's 52mm to 58mm, which is what has prevented me from installing my 58mm :\ (Yea, it's listed I know).
Here's the site someone here has followed, and I plan to, for porting it on the car. (Let the bashing begin!)

Read it ALL before you do it. The end lists some better ideas that the top doesn't, like using gear lube as well.

If you want to go 58, get the intake bored, and install the larger TB. All else will follow, IMHO.

koolaid_Kid it's your trans burn the damn thing up if you want. If proper tuning hasn't been done for your TB choice (a smaller 52mm, a transgo kit byitself, usually will do) you can burn the trans up. You're moving more air at less throttle angle. So since TPS is one of those sensors that help dictate line pressure, you're going to have less line pressure. Not good.

Yep, blasted 700R4s I was all happy to get my 93, I was about to go out and buy the B&M skift box, just temp, and then later on tune my trans up a bit. No dice :\ Makes me REALLY wish I had my built trans from my 91 now
Oh well, moving on. Line Pressure = GOOD. Trans, factory, ease (slip) into gear. So when you put more power to them, that's why they tend to last a lot less longer. A shift kit gives it more pressure, so it jumps (slams) into gear. As we all know, slipping = bad And thus, line pressure = good

Back on topic - IMO for the TB go 58mm and bore the intake if you are planning on going H/C or FI in the future. If not, then throw on a 52mm. Either way, get a good quality tune, and you will be happy with the results.
