MR.SIX · Post by **MR.SIX** » Sun Nov 12, 2006 11:55 pm

Im a dsm guy and i bought a starion to make into a track car. I love the all wheel drive. I just want a rear wheel drive to. go hang with at the track or drifting. I read the info on here about how to do it but it was confusing and i got lost in the almost to much technical side. I want to put the block in and either know how to make or buy the stuff to get a trans to fit. i would love to use the rx7 trans i know thier bullit proof budies got one and its nuts. please help with any thing i cna do or need to know on how to do this. A step by step would be sweet on what to get and do. I can do the whole other setup and swap but this is throwing me. IF IT WAS A SNAKE IT WOULD HAVE BITTEN ME! please help thanks.

Unless you want to find a wideblock and rebuild the engine, you're best bet is to go with one of Bill Hincher's W58 bellhousing adapters. If you use this you'll need to make a transmission crossmember, driveshaft, possibly do shifter modifications.

If that seems like too much work, you could use a D50 transmission. Other than the bellhousing, it is basically the same as a Starion transmission if you swap the tail housings. You can also bolt it up and use yoru stock driveshaft. You'll need to fab up some sort of a hydraulic conversion for its cable clutch. Examples are on my site in the tranmission section. You dont need to move the engine forward if you do the appropriate modifications for the water outlet on the back of the head (such as move it to the front).

The work isnt the problem its just the know how on what fits and doesnt.so would the 1g 4g63 be a wide block or no? and how much would the adapter plate be? What im looking for is strength and life of the trans. I have done to many allwheel drives im looking for a break.

The DSM 4G63 is NOT a wideblock

to repeat in a differnet way: The DSM 4G63 is a narrowblock.

The adapter bellhousings are around $400 then you need a W58. Driveshaft will be around $200, but you could do it cheaper if you were crafty.

It might be a little more expensive but it pays for itself around the time the 2nd D50 transmission that breaks.

1. Anyone know what kinda power rating or capacity the RX7 trans has?
2. Is the RX7 trans a W58?
3. Anyone know how the gearing compares between a D-50 trans and the RX7 trans?
4. Is the RX7 trans setup for hydralic or cable setups?
5. How does the shifter location compare to the D50?
6. Has anyone cryoed or nitrided a D50??
7. Or is that too expensive in comparision

The R154 is the mk3 trans and you can find it bolted to a 7mgte. Its built proof me and some buddies run them on 1J swaps with single turbos making big power and havent had any problems. minor scratching between gears in hard driving, if you find a bell housing that will bolt up to a 4g63 narrow let me know!

Thanks again for all the great info.
Not sure what I was asking in #4, but it was proably about converting the RX-7 or Starion to cable or even a MM to hydo.
