TWM makes aftermarket TBI throttlebodies. The generally mimic the shape of Weber sidedraft or downdraft carbs:





On the 20R, you would need to use their TB with a sidedraft intake manifold. On a V6, you would need to make a custom lower intake manifold.

-Jeff

Remembering that I know nothing about the 20r and little about the 22re couldn't you just take a 22re manifold and have a machine shop adapt it to the 20r head? Or are they that much different?

Its hard to put a round plug in a square hole.... forced induction would work, HAS worked...but getting that assembly to flow right with a naturaly asparating engine wouldnt be efficient at all. No amount of porting could line up the intake runners.

For some reason Im a little intimidated by the EFI stuff. I can do the factory stuff OK, but dabbling with the custom stuff un-nerves me. Ive had side draft carbs and they arent kindly twards us "Mudders". I guess TBI would be the easiest way to go.

So in all honesty how long should it take a noob to setup and tune their MS2?

Nuther question for ya. If I run the stock dist MS will still control advance/retard etc?

I haven't done MS-2, I've done MS-I. There are processor, pin out, and board differences.

If "setup" means assembly: I don't know, I've never assembled one. I think they take around 8-16 hours to assemble if you're familiar with them. They need to be tested after assembly. It's not easy to get it right the first time, you'll need a very good soldering setup, and a lot of patience.

If setup assumes a pre-built properly configured megasquirt & integrate with the existing wiring: With an adapter harness like what I've been making, about 5 minutes. If you want to build the harness yourself, probably about 2-4 hours, if you're careful. Crossing ECU wires is not good.
I've done most of the homework for you and I've tested the wiring adapter diagrams for the 22re.




For VAST igntion systems (IE - 22RE ignitor) it will give you total control over timing, 144 points of timing control total.

For 22R systems, you can keep the stock distributor and not worry about timing at all. Just do it fuel only.

You can do timing control over 22R systems also, but that's another discussion.

So I completed stage 1, which was do a stand alone system (no extra wires) on an 1988 22RE 4runner. I drove it for over a month and got it tuned to where I wanted it to be.

I've just finished stage 2, which was the complete overall of a 22RTE/22RE hybid w/ garrett t3/t04b turbo.
It was installed in the truck last weekend and I got it fired up and idling this weekend.
Oil pressure 60-70psi
Still running the stock fuel pump, we'll see how that works out. 440cc injectors. 2.5" downpipe. Exhaust not hooked up yet.
Finished finding all the little leaks, etc that new motors have. Setup the 60mm tb to idle.
Still haven't tuned it - no more time this weekend - need to add the wideband and better integrate the additional wiring.

It does sound like a flying saucer, however.. kinda exciting..

Congrats, Darin! Keep us posted once you tune it. How much boost do you plan on running? Pump gas or something else?

- Jeff

Well start with 5psi for the first 500 miles.
I expect peak boost to be similiar to your setup, when I get an intercooler... Depends on how the tuning comes out.

Street truck - no interest in breakingn the transmission via drag racing it.. I'll put it on a dyno once it's broken in.

Gee Darin, thanks for getting that motor all set up so we can drop it into my 4runner!! <img src="/forums/images/graemlins/kewl.gif" alt="" />
