throttle body plates-larger one

[unsunghero0]

for those who do your own throttle body modding...where do you get the larger butterfly plates from??

thanks!

[JazzyJeff]

All the ones Vin and I did we just tapered to the plate. I did a knife edged throttle plate for shits and giggles and the bitch came out nice! I even cut my finger on the bitch...lol. Anyways, I'm not sure if anyone has found one yet but you could look for a plate out of another car with the same holes but a larger diameter.

I used a plate form another t-body.

The neon 420a engines have a 52mm plate.

I hear the Geo Storm GSI has a TB that is swapable with the saturns.

It is a whole lot bigger to. You do have to make a custom bracket for the trottle cable though.

Someone correct me if I am wrong.

Yes the Geo Storm/Isuzu Impulse TB will bolt up to a Saturn intake. Its 65mm at the bore and 57mm at the plate. For best results you will have to port your intake. You will have to make a new throttle cable bracket.

Depends on if the car was a SOHC or DOHC I believe.

My Geo Storm TB is only ~53.5mm at the plate.
I did a light knife-edging and cut down the screws on mine.
Along with the new bracket, it swapped right on, not a single problem.

haha, how the hell did you find this old ass thread? lol

[yillo]

does it matter what year the Geo is?

[yillo]

One of my friend has a Geo storm sitting inthe back (91-93) not to sure.
To tell him to sell it to me.

I have a SPS true big bore throttle body for sale if you are interested.

[all4u]

I hope you're not planning to put a big bore tb on a stock motor. It is pointless. Yes geo storms have a swapable plate, and it does require some modding, a buddy of mine did it on a 94 SL2 and it looks close to factory. Very cool if you want that sleeper look.

Whats the stock diameter of the throttle plate?

[SL2clone]

50mm is stock. Tapering the TB is usless and pointless. Done it and has NO effect.
