The Toyota W58 Thread
This dude has been IMing me about doing the W58. I've always been skeptical but he sent me lots of links he is researching with and says he is getting parts today. He'll be sending me pictures to post and other info as well. Here are the links:

Getting the engine bolted in is about 10% of the way there.
The next 80% can go quickly with help and skill.
That last 10% takes about as long as the 90% that came before it.

the toyota W58 tranny is a copy of a Tremec T-5...I'm sure some strengthening can be done. People use this tranmission for all sorts of swaps in to old itallian/british/etc cars. Either way 350hp is alot more than a starion tranny can hold 
Not to mention a DSM narrow block is incredibly easy to find, also alot cheaper than putting a set of forged pistons in a 4G64. Besides, if you want a 500hp+ starion drag car, buy the powerglide conversion from buscher, it'll get you alot farther.
That being said, I didn't get the tranny that the local junkyard had as they wanted $175 for it, and upon picking it up it poured water from every orifice. I did take measurements though. Everything is within 1/4" for hole positions. Should be a matter of filling up the holes, laying a template down and re-drilling.
The other challenge is the clutch, as you have to use a toyota disk and a DSM pressure plate. I msg'ed one of the clutch retailers on ebay and they said it would be possible to sell a clutch package /w a toyota 6-puck disk and the DSM pressure plate. Cost would be ~$170
I'm going back to the junkyard this afternoon, I'll try to remember my camera and snap some photos of this whole setup.

Have you came across this yet?

It may be of help to you. I kept the AWD drive bellhousing from the talon I sourced my engine and parts from in case I decided to go this route. The transmission was dead already.

Not trying to hijack the thread, but the info I need may be useful for swap information. I found a guy online near me that is into building late 70's early 80's toyota engines, and I asked him if he had any spare RWD transmissions he may want to part with. One is from a 1.8, 3TC...it's a 5 speed
the other is from a 20R, or 22R, 5 speed. I've emailed him for the years and/or models, but haven't heard back yet, but do any of you know (or where to find) which W transmissions these may be? By the way, I had come across this in the past:

Thanks,

I JUST got this in the email.
Hello every one,
I feel I owe you all an explination,( especialy Richard Floyd) I have moved my shop to a bigger one and have worked around the clock trying to finish the bellhousing to mate the 4g63 to a w55 trans.
The pattern was the problem because the pattern for the casting had to be exactly 1 % bigger than the plans. I had built a sheet metal skeleton and filled it with bondo and shaped the pattern by hand from the existing model I had built using the adaptor plate. When I built the pattern I used all the Toyota clutch parts except the pressure plate ( which is Mits)
with the drawings and the pattern , plus the castings , I have spent about $8500.00 .It took extra time to find the money and have the faith that I can sell enough of these units to break even at about 50 units.
This will be my second casting, which is being done at this time, I ordered 15 units that I should have next week,( june 25th) after I get these units back I have to take the drawings to the machine shop and have them machined to exact specs, I dont know how much that will cost or how much time it will take, I have also built the proper jig for the machine work, so I will do the first couple units until I am satisfied with the results.
The bellhousing is thicker than the original and include two extra lower bellhousing bolts at the bottom of the housing to mount to the engine providing extra strength.
I will be sending picks and info to a website committed to the 4g63 rear drive swap at www.projectzerog.com take a look and maybe we can all work together and make something nice
Thanks Richard, I owe you one

He says he has $8500 into it now, which means I'm sure it will grow to at least $10,000. He says he wants to sell 50 to break even. That puts the price around $200 minimum for just the bellhousing. Are there 50 people willing to spend that? I can think of maybe 20 over a few years, but not 50. I wish him the best of luck though and will do anything to help.
