anyone have the 70mm t-body?

[dwnshfter]

what all must you do to use it, can i just get tom to burn me a chip to adjust the idle? will it bolt up to the stock manifold until i can get an aftermarket?

I think it will bolt up but in order for it to be useful you should be turboed or be putting out high horsepower. Its not really worth it the 65mm throttle bodies are fine.

i have a littel power, more to come though.

Don't quote me on this, but I think you have to bore out the manifold for a proper installation. It seemed like anything bigger than 65mm when I put mine on would just go over the plastic on the manifold flange and leave a 65mm hole anyway.

It's considerably bigger than the stock bore. I epoxied the mani then bored it out. You have no more idle air control passage, so where you set the tb set screw is where you idle, always. I've had one of pretty much every tb on the market, and can honestly say you won't get much if any gain from the 70 over the 65 and you get a few more hassles that probably won't be worth it. Just my 2 cents. I run the 70mm now

do you run it with the stock mani? and you just manually set the idle?

[mr.squatch]

Yes, I ran it with the stock mani, then on the other car with the 00 mani, and now on my car with the fc fiberglass mani. There is no way for air to get around the flapper like with the stock design and with the 65mm via idle air bypass. So you just gotta crack it open a bit with the setscrew. With the iac hooked up it tries to adjust it back to where it should be, without, it simply idles where you set it.

how do you like the fc intake?

[mr.squatch]

It's great. Most people who say they hate it or that it won't work have never even seen one. My car makes power from 4-8k so its not something most people need for their application.
