I think that's 83. I'm not sure if it bolts down to this version Ben made. Down the line I would like to experiment on the dyno with the 74 vs 83. I would time it a month apart after the first dyno to let the ecu adjust to the other throttle size.

Well I scored a used 74mm tb for 70.00 shipped on ebay. The average lately has been about 100 bucks used. I hit him with a 60 dollar best offer and he refused it. Waited about four days and offered up 70.

You're lucky with that price. Average price here is £120 but I've managed to pick one up for £70 all in

Nope, the 83mm doesn't bolt for now.

I don't think it would be suited for the boxster' small engines.

I can do one for the GT3 TB if someone wants to try it!

The last one is on his way to the other side of the ocean

I'll give the GT3 TB a shot if you're up for it Ben!

I 2nd the 83mm. I know its big, but I think it has serious potential especially with a tune.

One thing I must add, I siliconed the tb to the plenum before the install thinking it would be easier. Don't do that. The added weight of the tb makes it hard to maneuver the plenum when installing the boots. Both the intake and the plenum got plenty of clamping areas so I might go with the silicone boot instead of the oem.

If you already have them, or if they are really cheap, why not

The GT3 on the 3.2L at least, I don't think the 2.7L has much more to offer :/

Well, I know what I'm going to do during the hurricane!

Got mine today looks great! Sorry about the violin symbol. Have no ideal how that got on there. I got to figure out if I want a metal color or going to do red.

This is the 74mm version(99760511501), whereas the 99760511601 is 82mm for GT3RS.
