Found this on ebay and wondered if the price is too high. Would I be better off finding an automotive machine shop locally to bore mine out and make a new plate? I'm in SoCal. Thanks.

Thank you. Evidently it sold overnight and has been removed. Fortunately I got an offer from a board member to purchase the same one used. Thanks all for looking.

If your going to upgrade your TB, just the MP 60mm or IMO its not worth it.

+1, its an awesome throttle body. This is what gets me though, I have a buddy who has a honda hatch that does better than 14s in the quarter on all motor. I told him I was getting a 60mm tb and he was like "thats it? why so small?" Apparently civics come with around a 60 on it, and he was running a 70mm. I told him how ours start at 52 and neck down to 49 and he was like holy shit.

So when you think about it, unless you can build a 55mm using a dirt cheap jeep tb, Id just go full 60.

Lol, so much to think about. I'll keep you all posted but I'm already buying a 55mm. Maybe I'll just get a Jeep TB dirt cheap from the junkyard and start another project. Can always sell off one or the other.

Hey, what's this half shaft mod? I understand it acts like a 57mm. Sounds like every little bit helps here. Thanks.

My bad I had it backwards, I thought it was 55s that could be found every day and 60s were harder to find.

In the end it really comes down to what you want to do, how much you want to spend, and if you are mechanically inclined enough to handle the jeep tb mod. If you are, its cheaper than buying a new one. Sometimes WAY cheaper.

I can set up a 55mm for $100
Is that cheap?

Or just follow Dino's example and run a 90mm throttle body. I wish I could find the picture of him stick his arm up to his elbow in the intake manifold.

i have a question, on a extrude honed stock intake, with BC stage 1 cams, injen 1 peice CAI, relocated AIT, would a 55mm TB be too big?

No.

how big can u actually go on a mild setup like my mothers, i havent had the chance to get it on the dyno and check specs

It really makes a big difference huh? How much is a mm in decimals anyways?

1mm is 0.03937in

Doesn't seem like that much of a difference but when you start calculating the volume of air that can flow though is does help alot. Also I bought my jeep TB off ebay for $20 shipped I believe. Took a few weeks to find a cheap one but it paid off.

Thank you, that's just over a 32th (.032) of an inch. I understand that even though seemingly small it does contribute to a much higher flow. I'm going to do that 1/2 shaft mod to the TB when I get it for sure.
