20V MK1 Engine Swap Will the stock ST 20V AFM, coil and igniter work

tnturbo · 05-12-2008, 05:43 AM

or do I need to acquire other parts for a swap into an 89 NA 5 speed. I have all that stuff with my 20v and it all looks good. Is there any reason to change to US model parts other than availability. In other words are all the lists floating around of parts what you use for replacement or what you must use for the swap. How about the wires, mine look good as new. Motor is clean as a pin inside, under valve cover and inside oilpan. What about the starter, keep the ST starter or use the 16V one. I'll be using the 20V tranny and installing a new clutch while it is out just to be safe, also replacing all seals even though there are no leaks, timing belt, plugs (though they look good), etc as I don't relish replacing any of them while in the car.

to my knowledge one MUST have the 20v ignitor and coil. The AFM will work also, or you can get one from a 3S-FE if for some reason it is bad. While its all out is also the perfect time to put a flywheel in too

I also did water pump while it was out just to be safe.....

mine is not finished, with that said most of this info is just regurgitated from elsewhere on this board.....

For electrical parts, availability isn't even a good reason. The 20v igniter can also be found on 92 4runner v6's, mk2 mr2 turbos, and toyota pickups with the v6. There are a ton of other substitutes that can be used as well.

So, just use what you have.

is it safe to assume the coil from these vehicles will work as well?

Not always. There is an earlier variant of the 20v's coil that has a wider coil wire fitting. It is used with igniters prior to say 1993, though that's not an absolute cutoff date.

For example, I like to use the igniter from 1991 Previas. I can use the igniter, but not the coil. At least not without mods to the coil wire.

The 20v coil is common. If you're looking for a replacement, just order one for a 1991 mr2 NA. $55 at autozone.

without hassling you too much, perhaps when you get a moment write a sticky on 20v parts from the american junkyard? what does and doesnt work!! i know we have one for part numbers, but same parts from other vehicles would be awesome for the junkyard dogs!
