MR2 Spyder / 3100 Swap

[Quinky]

You'd want to go with the getrag 282...

[Stevesr]

I assumed you meant only one side...

As I was falling asleep last night I had an idea about this, kinda off the wall, so try and follow me, I hope I can explain it.

You have to make an adaptor plate to adapt the engine block to the tranny, so that will add some space, say 1/4" to 1/2", so you will have to space the flywheel equally. What I'm thinking is that there might be a way to adapt the Toyota flywheel here. Throuhg use of an adaptor plate, or my really wacky thought, use the 660 flexplate, and bolt the Toyota flywheel to it. This way you have the proper ring gear for the 660 starter to engage and the clutch surface is complete covered as per factory. You may have to make the adaptor plate thicker or thinner depending on how thick this assembly becomes.

Like I said wacky thought, but might work.

Raven your idea is not wacky at all,I don't mean to highjack your thread,dmc12mk3, if I can add my $.02 here. For my 3.1/Porsche 914 project I purchased an adapter plate from Kennedy Engineered Products and what you are suggesting is what they do.I sent them my Porsche flywheel,they welded it up and re-machined it to fit the V6 along with the adapter plate that sets everything in the right position to use my stock(or after market if I choose) clutch pack and release bearing. And the stock Porsche starter.......Now back to your regularly scheduled thread......

Steve, what was the cost on that from Kennedy?

[Stevesr]

As I remember it was $455 for the plate and flywheel machining. They did a "pro" job,when I got it back the plate and flywheel bolted up like it was "factory". The cool thing is you can use your stock clutch or any aftermarket heavy duty you want to that was designed for your car.

[Stevesr]

This is kinda what you get......I don't think they adapt to the Toyota transaxle but if you sent them a "rubbing" they would probably make one for you....at a price$$$$$$

yeah, it appears that I'm going to have to send the bellhousing out to Wilcap to get one made. Which sucks because the bellhousing is part of the transmission casing and up until today I thought it was separate.

The FWD GM trannies that will bolt up to the 660 are all about the same size, with the Isuzu being the smallest, also it's been said to be the weakest.

I would look at the 282 as well, the 284 is also an option.

late '80s to early '90s FWD 660 equipped vehicles, like the Cavalier, Beretta/Corsica, '91 and later Sunbird, and others that I'm not currently thinking of.

Thank you Raven, that was exactly what I was looking for.

btw - I took some measurements this evening, as well as some pictures of the engines next to each other. About the same height so I don't think I will have any issues there. My concern is on the length of the engine. It appears that I'm running just over 20 inches from rear of the block to the tip of the crank pulley. With the additional space necessary for the 1/4 inch adapter plate it might get really tight. I'll know for sure by this weekend.

edit - added the pictures

[Stevesr]

Your plate might end up being more than a 1/4" depending on the clutch pack.....just something to keep in mind

isuzu trannies are weak. mine is a POS. MT2 or something. the fdr is like 3.45 or so, not real sporty, but better than the autos i guess. gm pinched their pennies on this deal, bought everything with non-hardened parts to save a few bucks. the isuzu built gm's suck. mine grinds just to grind it seems. isuzu cars have stronger trannies (450+ ft/lbs i think vs. 200 or so), isnt that embarrasing?

mantaparts has a 4.11 final drive for it though.

[dmc12mk3]

Well, the V6 won't be bolting up to a C60 anytime soon. One minor detail that I overlooked in all this and what was made painfully aware to me this evening is that the flywheel is bigger than what the Toyota bellhousing can allow. Seems like I would have thought to check that before physically putting the engine and transmission together. Anyhow, so what I'm looking at is a plate that backs the engine away from the transmission about 1.25 inches. That won't fly as far as my clearance issues with the passenger side frame rail goes. I was running pretty tight (~1/2") with just the added length of the V6 and the quarter inch added from the plate.

I thank ya'll for your assistance and information that you offered me.

So it looks like you'll be looking into using a v6 tranny then? I think it would be easier to adapt axles than the clutch anyway.

It would, but my ultimate goal with the swap was to be able to sell a kit and allow others to do it too. I figured if I got it to work out where all you needed was the adapter plate and a motor mount along with the engine necessities that it would be a pretty good option for the rest of my SpyderChat cronies. As it is, I'll see about coming up with a 282 transmission for this motor and getting a local axle guy to come up with something that will make it work. That will have to wait though, for now I'm just going to spruce up the 2zz and put it back in the car.

btw- The flexplate that came with this motor was about an inch shorter in diameter than the flywheel I have. Do the FWD setups use a different size flywheel than the RWD counterparts? My flywheel/clutch/pressureplate are from an old Camaro.

For what its worth, check out Overrev magazine. There are advertisers in there that claim to make custom flywheels and clutches for imports. Also, as a side question, why are you yanking the 2zz engine anyway? What are your plans for it now?
I noticed your screenname, do you own a De Lorean? I am a rather fond follower of this car as well.
Peace out,
Jeremiah

Oh, and BTW, if your looking for a GM 5 speed tranny check this out http://drivetrain.com/transmanualreb...EVROLET%20CARS
Where you see it say "Muncie" is actually a getrag (the prefered tranny). Hope this helps,
