87GN Stock Throttle Body Question

[granitestategn]

Porting the intake on a garage queen ? WHY ? Leave the car alone an drive it to the car shows. 99% of people have no idea what they are even looking at.

TWIN TURBOS? Of course they do!
The one that's on the car, and the stock one on the shelf in the garage!

bwahahaa! 1000HP!!!!
Stock ignition. Vacuum block instead of push loc lines. Stock intake and throttle, and a MAF-T... so it's on the stock ECM still.

I really like the billet look. At one time somebody made a 65mm billet throttle body, but couldn’t find it when I was ready to purchase. I haven’t seen it since so I had Steve do my stocker.
I decided to go with the precision plenum and power plate because of the slightly better air distribution over the stocker. This route made sense to me when purchasing flow matched injectors.
A word of caution: the Precision plenum is 5/8” taller than stock to clear a 4” MAF pipe so it’s very close to the hood liner. Notice the slim vac block. I had the plenum machined to tip the TB down and to tip the plenum forward. Then Cruze comes out with the angled spacer. ARGH!! Lol
I got the cast version and had it powder coated anodized aluminum w/ clear along with the valve covers for a stock look, only better.

I recall a post either here or on FB, that someone else was going to start boring the OEM TB like Steve offered.

I don't recall who though. Sorry. Maybe someone else will chime in with better info.

Greg Wahl at Altered Machine has these available now. See my post for more details

When I put a larger throttle body on mine, I initially liked the extra throttle response it had off idle. But now, I tend to creep up on opening it just so it softens it some. Using DBW ECU's, you can taylor the amount of tip-in response you want.

Greg does nice work. The half shaft mod was a better mod than others.

It dose look like a very nice job. I was a little skeptical about the teflon gasket, but after a little thought I like it
