Here's the scoop: I'm now looking to build adapter plates for the Mitsubishi engines. In the passing 2 years, I've aquired alot of vital infomation on the bolt patterns. I currenlty have dimensions for the 4G63, 6G72, G54 and the 420A along with bolt patterns for various Chrysler, GM and some Ford(still working on it) transmissions. The plates would be steel. This makes them cheaper to produce and if someone were to use this as a mid-motor plate, they could easily weld to it.

Now, at the same time, alot of you are looking at other foreign tranmissions to use in RWD applications. The toyota W-58? comes to mind. I don't have dimensions for that, but do have connections to Nissan. So, question is: Is there a Nissan transmission that many of you might consider using?

I'm in the process of getting quotes from several prototype companies in the area that I have already had dealings with before. There would be no Group Buy crap. We've all seen that go south on too many times. I'd front all costs. You'd simply buy the product. For prototypes, I'll be offering two souls the oppertunity to have (at a seriously reduced cost) an adapter plate to use/keep. In return, I'd expect feedback on the plate.

Second, the person(s) I chose to 'essentially give' the plates too, would need to be deep into their project. Meaning, not someone that wants to a Mitsubishi powered (insert name of car) down the road 5 years or 2 years. It'd have to be within a year or close to. The farther along you are the better. If you think you fit the bill, PM me.
Third, is there anyone willing to utilize a Chrysler tranmission in their RWD application? The most complete specs/tolerances stack-ups I have are for Chrysler applications and I'd prefer one of the first two be Chrysler. The second one a GM application. This also opens up the door to utilize Chrysler FWD transmissions in DSM's. There are some good Getrag trannies out there.

The intent with these is to use a block/trans adapter plate in conjuction with a crank/flywheel/flexplate adapter plate. This allows you to use a much larger Chrylser/GM/Ford clutch with the Chrylser/GM/Ford flywheel/flexplate. The result: Larger/cheaper selection of clutches to use. You would have to purchase the corresponding flywheel with your tranmission.

so basically what you are intending, is if some one wanted to put a 6G72DETT engine in their 240SX(or other RWD project car), they could bolt it up to, oh, say a T56? Just one of the many design possiblities here, but this sounds profitable if you can market it. props for your work so far. Your theory has many possible outcomes here, i'd like to see it in action :thumb:

Yes. 420A? How about an A853 out of a SRT?

A ton of possiblities here. I think, once I had the intial prototypes built, and had 2 out there with people on running vehicles, it would sell like hotcakes.
 
Hm.. How interesting.. I wonder if I could use one of these to take one of my old 350 LT1 small blocks, turn it sideways, and fit that in a DSM?...
 
Just PM'ed you

In case other people are intrested:

I'm doing a 4g63 swap into my 89 Conquest and was going to use the Dodge D-50 trans, but I am willing to buy/use/ test one of these adapter plates!

Mike

PS: In case you guys are wondering, the G54B is the stock engine in the conquest and it uses the mitsu wide block
 
Jus wondering if you have made a plate to bolt up a 4g63 to say a Gm turbo 350 or power glide tranny? I have a 1966 Nova that I was contaplating doing a 4g63 swap into. I was looking into doing this to be different from the small block crowd. I have a 91 GSX now that is fairly built and i love the way it pulls. I would like to see what this could do in a classic muscle car that weighs in at 2,900 lbs. Keep me posted on the tranny adapters, thank ya
 
Is eric plebani still in the dsm world? i used to talk to him about these things on irc all the time, he's definently the man when it comes to shoving a 4g into stuff it doesn't belong in :D

Thats an original idea, you will probably be the 1st and Only one to do it. IMO... Rice and DOM does'nt go together. GM with GM, Maybe a Buick Turbo V-6 in the Nova. Or a SuperCharged 3.8 in a Classic 66 Nova.
 
I have already seen a couple of buick 3.8 turbos put into Novas. I have also seen a 63 with the factory 4 cylinder with an aftermarket turbo installed on a carb motor. I myself have helped do a 5.7 tuned port swap into a 63 Chevy II. I just think it would be different to pull into the local cruise spot and pop the hood and see a turbo 4cylinder under the hood. Its like seeing an old 510 Datsun with a 13b rotary installed. Mixing new technology with classic body lines. I have the resources to fabricate motor mounts and oil pan to do the swap, its jus a matter of bolting it up to an GM tranny.

Which flywheel & starter would you use?.....and a GM starter bolts to the block, not the tranny. John Sheopard's Eclipse is RWD, which tranny does he use?

ummm... shep is awd.
 
buschur had a rwd tube talon.. dunno what happened with that car, they now have a rwd "street" starion with a 4g63T

plebani was the first to put a 4g63 in a starion afaik, he also put one in a porsche 911 and in a mitsu pickup. The last time i talked to him was a long time ago and he was pondering putting a 4g in a jeep and in a 240sx.

No. Buschur essentially already did this. He used a powerglide which has the same bolt pattern as most of the GM turbo series transmissions (200, 200R, 350,400,700R4, etc)

Right, this is nothing new. Buschur did his first Powerglide RWD, back in ’97. He has also been offering them for sale and it would surprise me if he sold more than 10 of them in the last 7 years. So American V8 automatic business seems to be pretty dead…

BR’s original RWD Talon is now owned by my friend Bruce K.: http://www.mightymouseracer.com/

Manual transmission business is a bit different, I can see it being much more feasible, but isn’t there a company in Florida that already offers such plates for Toyota trannys?

Morphius, do not get me wrong, I do not want to discourage you. I LOVE engine transplants and since 4G63 is my favorite engine, that is my favorite type of transplant! I just hate to see you put all that effort and money into something that might not prove to be very profitable. Unless you are only doing this for fun ;).

If I didn’t already have a nice Plebani Build D50/Starion hybrid, I probably would have taken you up on this offer!

As far as I know, it's a rather expensive 'kit'. On the order of $1500 for a adapter plate, flywheel, crank adapter, and custom torque converter. And I beleive it's aluminum, which isn't cheap.

Mine would be a block and crank adapter. You'd use the flywheel/flexplate that goes with the tranny. And I'm 'estimating' it'd be well under $500. Still waiting on preliminary quotes from the supplier(s).

Anyone know who? If it's the one I've come across, I have yet to find anyone with an example.

If there wasn't fun involved, would we all still here? I wouldn't get rich on it.

Right, but that “custom torque converter” alone was around $800-$900, so you are “only” paying $600-$700 for everything else. Do no ask my why those converters are so much money, I know very little about auto trannys :).

I am going to see if I can find them. From what I remember, they made adapters to 4G63 to a Starion and to a Toyota trannys.

The best RWD toyota tranny to use would be the R154, used in the MKIII supra turbo. It's rumored to be as strong as the indestructable Getrag V160 used in the MKiV TT.
 
So why not just find a V160 to use? that would make sense too i guess :confused:

think of what we could do with a RWD 4g63 powered car with an indestructable tranny, we wouldn't have to worry about breaking half the sh!t we break on these cars, and we could focus more on the motor than anything else.
 
I would think a 5 speed non-import v8 trans (ala. t5) would be the best idea.
There are a million of them in every local yard and you can do every mod/upgrade under the sun to them.

Cause when you do find one (almost never) they are over $2000.... What you could buy a couple brand new Ford Racing T-5's, or a new Richmond Gear 5 speed, or almost a new richmond gear 6 speed.

A R154 can be found for a couple hundered - W-58's can be had for a song...
 
Morphius, You might want to talk to Horsepower House too. They run a Conquest w/ a 63 and a Powerglide. He told me that they were putting together a kit too. Didn't know prices then but that was last fall.
 
I'd bet there would alot of interest in this from the Starion/Conquest community. I'm posting a link to this there.
