EFI throttle body with adjustable idle speed

[CrUZida]

Did you want a TB with an ISCV, or a TB with an adjustable butterfly stop?

If its just the 2nd one you want, then pretty much all Toyota TB's have this.

I want a throttle body with an adjustable throttle stop to adjust idle. Something common with dual flanges if possible. Any ideas?

Rob: The camira EFI TB that I have is a two-plate thing and a mechanical link between the small primary and larger secondary. Am not sure what motor it came off - at the time i was just scrounging for EFI stuff for my 18RTE.

The inlet is oval shaped, and the flange plate is rectangular like a 2bbl carbi.

I got it as the mounting flange suits older bosch TPS sensors. It has an adjustable throttle stop and a bleed screw for an air-bypass.

Thanks Chuckster. I guess I'm just going to go to pickapart and have a good look around to see what will work.

Thanks again

even 4age's have screw adjusted idle, as do pretty much every Toyota TB i've seen..... but most later models (like the 4age) also have the auxilliary air valve (wax pellet) for cold starts.

I was going to say, nearly every 80's, 90's Toyota has what you're looking for, the provide some level of idle control, but obviously has no method of compensating like an ISCV does. The ISCV does extra things like being fully open at startup to help starting, and adjust idle for temperature etc.

Later A-series engines ditched the screw-adjusted and went to the electronic ISCV (gets rid of a bunch of idle-up valves and vacuum piping), whilst still retaining the wax-pellet cold-idle valve

Except the smallport 4AGZE, that one is all ISCV.

16V 4ages still had idle screw TBs.... the 20Vs had quad throttles, so they dont count.
4agze is just different.

Was referring to 7AFEs and the second-gen 4AFEs
