MR2 in the making

There should be like 3 sensors in the distributor if memory serves me.

24 or 36 tooth - i can't remember how many tooth there is but it is there
4 tooth
1 TDC tooth

Just take apart the distributor to see what wires feed what.

You can tap into one or two of those. I recommend using the TDC tooth for one input and one of the multi tooth input for the other. You should be able to pick the wires up by the stock ECU if you have a pin out chart.

I helped out on putting a 20v in a mr2 MKI and went with the custom crank setup tooth wheel.

I wish we went with the distributor! it would have made our lives a lot easier. The multi tooth wheel by the crank looses signal. I blame the bracket that the hall sensor sits on. Need to better engineer that. after that it will work just fine.

However it would have been MUCH easier to tap into the distributor instead.

PS later down the road you don't even need to use the distributor for your ignition! You would be using it like a cam sensor instead.

the 20V is running a DSM coil pack controlled by the MS2. Works VERY well and is an ignition upgrade compare to what was there.

the 20v 4age and the 3sgte are not all that different. both have cylinder heads from YAMAHA

There are 2 wheels 1 24 tooth and 1 single tooth wheel. Three VR sensors read these, 1 on the 24 tooth and the other two read 180 degrees apart on that glorious snagletooth wheel.

Personally if I didn't want to mess with a 60-2 custom trigger wheel setup (which is best, more resolution once you get the hall effect sensor spacing setup, as you pointed out), I would go with a Honda distributor adapted on the 3sgte, then might as well go Honda ECU as mentioned here:

However, I sold my MR2 and now am rocking a busted AEM EMS in a stealth

Not quite done yet. Installed a 94+ wing. Filled up the holes on the trunk and re-drilled to fit 94+ wing. Replaced cracked windshield.

[b00sted_spyder]

Bump it up.

You drive that thing in the winter?

I always loved mr2's, would love to have a beastly one some day

[b00sted_spyder]

Oh no way. I just pulled it out just to idle.

[b00sted_spyder]

I'll leave this here.

I still remember reading about an MR2 in Turbo magazine that would pull the front wheels on street tires, that always stuck with me. I'd love to build one of these as well. New paint looks good!

[niterydr]

Like the new paint!

[1ViciousGSX]

Nice!

[turbotalon1g]

What? No more white?

[AwdGSX13]

Really like these cars! Always though that they are probably not too fun to work on though when it comes to putting in a clutch ect.

[b00sted_spyder]

White is nice but you dont ever see this color around here. It is oem 98-99 cosmo blue which of course didnt make it to the US. Fixing parts on this thing do suck. I just replaced the alternator and had to drop the axle instead of pulling the alternator bracket. But overall, it's a super fun car and will never go out of style in my opinion.

Looks good, I haven't been in one of these since early 2000s I think.
