Would anyone be interested in....

A kit to convert a narrow block 6 bolt 4G63 into RWD. It would include used motor mounts, used D50/Mighty Max transmission, and a used 6 bolt flywheel. I am figuring cost at around 450.00 plus shipping. I have tested this combo up to approx 400 hp without breaking anything transmission/clutch related in a pretty light car. Anything making more power should probably not look at this option. I will provide the special part #'s for the ACT clutch/pressure plate for this set up when I send it. Just order the clutch, surface the flywheel, and bolt up the trans. In early cable actuated clutch mitsu cars, this is a bolt in with minor mods to the trans mount. I am serious and will put one together if anyone shows interest. I offer real CC processing (not paypal), and we have over 1,000 ebay transactions (power seller) with a 99%+ positive feedback. Post here or PM me if interested, and we will go from there.

Considering people now have these bell housing adapters for toyota transmissions, I dont think anyone will be using the d50 boxes unless its a na application.

I have, in a pretty quick drag/street car with nitrous and lots of boost for several years with great results. I know that I have exceeded 400 HP on several occasions and it did not explode dispite what I would characterize aggressive shifting. I don't think they are junk based on my experience, especially for the budget minded. As long as someone was looking to make moderate power in a reasonably light chassis, I really doubt you could fault the transmission in my opinion. Whats the fastest 1/4 mile E.T. anyone here has put down here? Peregrine matched my E.T. (at the same track) with a bigger motor, tire, turbo and no passenger. I do speak from actual documented (and videoed) experience, not just theroy and internet "hearsay".
I am not saying anything bad about the toyota trans or any other trans/bellhousing combo either. I just did not like the way the toyota trans shifted in my opinion, thats why I have decided to go a different route. My next car will not have a D-50 trans because of the power it will make, but up to this point I really have nothing bad to say about it. I will make some passes in the next two months with approx 500 hp on a D-50 trans, and I will post how well it holds up here. I know they have a history of bearing trouble at that power level in a drag race environment, but I have a light car and I hope to keep it together till the next car is ready. Now if someone could make an inexpensive narrow block T56 adapter to go along with the flywheel they make, I would already have it in the car

Bummer. I guess I have managed to always pick the best of the bunch, four times in a row

. I agree they are noisy after you try to put any power through 5th gear (not recommended BTW), and that weird noise they make when you let off while cruising is hard to get used to as well. I say again though, I have beat the living crap out of several of them with much more power than the combo you described above without ever having a failure. Since I stepped up the power above 400 it dosent like to go into 3rd as easy and makes some more noise than usual, but I have still never broke anything. What did "mike" break on all of his?

The only problem I had was input bearings. I'll probably be selling my D50 Transmission with slave cylinder, clutch, flywheel and extended driveshaft in a few weeks.

That noise you hear...not a good sign, it's bad bearings, so selling someone a swap kit w/ a noisy transmission probably is not a good idea

OK maybe you are having trouble reading what I have posted. I am not sell anything that I have beat on, raced or previously swapped. I am selling stock take outs from D50's that are in good used condition. I check the oil when they are pulled for any evidence of damage or long term wear. Any clearer? I sell used parts to people every day, and I feel comfortable selling them, despite what you conject.

As far as your locked up trannys that the bearings fell out of, I am sorry. I have not experienced this despite stepping off the clutch at 5000+ with slicks at a track (would you like to see video?) for more than a year on the same trans. In fact I have broken axles before spitting out transmissions, so as far as what you guys have done previously I cannot explain because I was not there. There can be many reasons a part fails, including lack of service, a bad install (did you guys change the TO or pilot bushing after going through trannys like underwear?), or perhaps your guy used a different clutch? How about limiting the the amount of engine/trans movement in order to avoid any flexing issues? Again, I just thought maybe someone was looking for a cheap way to enjoy having a RWD 4G63 car like I have. I have had great luck despite all of the intraweb hype that these trannys are made out of balsa wood, but are still connected from the factory to big diffs with 6 lug wheels. Luckily this site wasen't here when I built my car, I would proabably still be trying to bolt a lenco to it just drive to the 7-11

What happened to the bearings? How much power were you making? Did the trans see high RPM for an extended period of time in a low gear (drifting?). I think your set up is perfect in a budget car, were you dissappointed with it?

I totally agree with you there with cheap transmissions holding power. On both occasions the pilot bearing was new, as was the TO bearing and clutch and flywheel was OEM resurfaced, but the transmission still failed. The noise in these transmissions appeared instantly after installing them, it wasn't a problem that developed after driving. I'm not saying they can't hold power, because we never had problems with the gear strength, only the bearings and their inability/lack of design to turn any significant input shaft speed (7500rpms+). The D50 transmissions have proven to give problems to cars that put on any sort of mileage, maybe you got the fluke 4 best ones ever, who knows, maybe we got the worst 2 ever (doubtful by the feedback i've read). Regardless it may be worth it to install new input shaft bearings and still sell them at a good rate.

I would not be able to sell them that cheap if I had to put the extra labour in them. I shift my car at 8500 (8465 according to my DSMLINK), and I have put a ton of mileage on several of mine. Fluke or no fluke, I cant complain. I don't dissaggree that changing the imput bearing would be a good idea, I am just saying I have never had to. I have always changed my pilot bearing as well, thus reducing any strange side loads that the imput bearing would see. Maybe thats what has helped. Either way, if anyone is building a top fuel car or a 20,000 RPM drift car, then like I have already said, look at other options. The D50 dirtboy built will be the real test. His stuff weighs more than mine, and he will make over 400, so we will see what happens.

I think the package/kit you're putting together is a great idea. Matt.. shut the fuck up already. We've both posted my experiences with the D50 transmission. Let everyone make up their own minds.

I'd like to see many more swaps out there and a cheap entry level solution is a great idea.
