Velocity Stacks on a 7AFE

Has this been done?

I would like to do it, but what do I need to take into consideration?

I know this is vague but I don't know much about them.

ITB's would not be worth it, the cams and head itself will impede flow before the manifold does.

AFAIK, it's never been done before.

If you want ITB's just get a 4A-GE 20V swap. You'll get a nice boost in power over the stock economy engine as well.

Frankenstein. Add the entire 20V head with ITB's.

sounds like it has no torque. Would like to see the dyno since I know what a 7A should make.

Good god, I hope there's at least stacks on those quads and that they shimmed the hood (old-school trick) to get some more air in there. It always seemed nonsensical to me for the Toyota crowd not to be running an airbox when the FWD mounting has the intake at the back and against the firewall.

Makes me almost envy the Neon guys.

Edited to add a little more information: The ST/BT throttles were what, 46 and 48mm? You wouldn't want anything under 40mm, that rules out a lot of bike throttles, and the longer stacks/intake runners you can get, the more usable power you'll actually see. Go look up Helmholtz resonance. You won't fuel them with the stock ECU, too many midrange fuel changes and a positive bloody nightmare to do IAC with unless they're equipped for it already. A LOT of the Honda folks have tried motorcycle quads and there's a wealth of information out there.

(For reference, the set of throttles i have within arm's reach are from the GSX-R 750, Factory Pro stacks, custom T3 remachined adapter...and they were used on an otherwise stock bluetop to great effect.)

and forget about getting steady vacuum for anything that needs it unless you built a vacuum tank or get an electric vacuum pump with tank...

1. Toyota A-series engines have the intake on the left of the engine (when looking from the timing belt). In a FWD layout, this means the intake is at the back of the engine bay next to the firewall. If you are running velocity stacks and no airbox, there isn't great airflow to the area and it'll be quite warm too. Some other manufacturers (and some other Toyota engines) have the intake on the other side of the engine (so that it's at the front of the engine bay), which gets better airflow.

2. The Chrysler/Dodge Neon is an example of a car of similar size/age to the Corolla with the intake at the front.

3. Bluetop = gen1 16v bigport 4AGE, so-called because the writing on the cam covers was blue. Since you're also from Oz, it's the engine that came out in the AE82 Twincam.
