RWD TSI, Clutch?

emagdnim · Post by **emagdnim** » Sat Jul 23, 2005 10:18 pm

we have a 91 TSI FWD that was coverted to RWD with a D50 tranny out of a Mighty Max truck...

Well.. the short of it we had slipping problems with the max clutch so what upgrades if any can we put into the tranny to make it not slip?

I seen a disk by ACT, i was going to buy it tonight to get this thing to the shoot-out, but i just want to be sure what im buying will work.

thanks guys.

your new noob.

Which flywheel are you using? Just be aware that the splines on the transmission are NOT the same between the D50/Starion and the DSMs. If your clutch was slipping you might want to consider replacing the flywheel anyways as it may be warped. In that case a DSM flywheel will work and you can use a 225mm disk on a Starion center. Any respectable clutch company can set it up with minimal effort.

And what pilot bearing do you use with the larger shaft? machine the centre of the DSM flywheel and put it there? has anyone got pics of how that works?

Post by **DJpowerHaus** » Sat Jan 28, 2006 2:37 pm

I had the flywheel machined to fit the Starion pilot bearing.

How has your luck been with those transmissions? I killed one every 6 months making a touch over stock power, but with a good clutch.

is the bearing as thick as the flywheel, ie. the hole goes right through? so it just presses in there?

Post by **DJpowerHaus** » Mon Jan 30, 2006 1:30 am

I think the flywheel is a little thicker than the bearing.. There is supposed to be a step in the flywheel, but it really isnt important to have... and probably safer not to.

Stock Starion flywheels have a step. Matt killed 2 of my flywheels (becuase I told him it didnt matter which way) by pressing the bearing out the wrong way.

so you can confirm the AWD flywheel fits in the mm gearbox? it looks really tight! what release bearing do i use? and will the VR4/DSM starter bolt up?

I am looking for a disc, so I though it would resurrect this thread instead of starting another one.

AWD flywheel is smaller than the D50/MM flywheel so it will not match the starter location, but FWD turbo flywheel should work just fine.

Is there an actual application (perhaps Mazda or Mitsu?) for which we can get the disc to work with Starion/D50 tranny and Turbo DSM pressure plate?

What else has a 1" 23 count spline center? Maybe there is a Ford disk that is 225mm, I know some Fords used 1" 23 count spline centers as did some Mazdas.

On that note.. has anyone prefected using a D50 transmission yet? I certainly wouldnt go that direction again.

GRNDSM · Post by **GRNDSM** » Tue Oct 10, 2006 3:53 pm

Perhaps, some day...

But for now, I would like to use my '88 Starion tranny with D50/MM bell housing that Eric Plebani built for me. Everything (tranny mount, shifter location) is just perfect at the moment, so I would rather not mess around with things.

And by all accounts, ’88 Starion trannies are pretty strong, so I do not see an advantage going to a Toyota tranny.

Sure, my project goes WAAAY back to 2001. Before wideblocks were "discovered" or tranny adaptors were popular (or even available)

.

I parted out '88 Starion (keeping its driveshaft, tranny and for short while its rear end) and picked up 89 Mighty Max tranny/clutch/motor mounts. I attempted to built a hybrid tranny, but I was reminded that I am NOT a tranny builder… Fortunately Eric was able to make sense of my mess and put together ’88 Starion tranny with Mighty Max bell housing.

Had I been starting this project right now, I definitely would have gone with one of Bill’s housings or just built a wideblock.

I forgot about your hybrid transmission as well. Should work awesomely. How are you doing your slave cylinder?

Still no advice on what part number you'd use for a disk. Wasn't there a 225mm Starion disk?

GRNDSM · Post by **GRNDSM** » Wed Oct 11, 2006 9:47 am

I haven't yet addressed the slave cylinder. But most likely, I will try to adapt a TR7 slave, if it does not work, I will move onto Wilwood or some other similar aftermarket unit.

Aren't there a bunch of people with MM/D50 trannies out there? Are they all using small truck clutches?

So basically, I have to ask ACT (or any other clutch company for that matter) if they have 225mm clutch disc w/1” 23 spline center.

Speaking of Starions, what was the size of their clutch disc?

Edit: this is interesting... ACT lists part number MZSD069 as the disc for '88 Starion. That number comes up as Mazda RX7 TT clutch disc

. Now, I just have to find out its diameter!

So much for that... Starion/RX7 TT is using 240mm clutch

I just went through the entire ACT catalog using AT03 Starion alignment tool and 225 as my search. There isn't anything that is available off the shelf

.

Looks like I am going to have to make a custom disc. Or just use 215mm disc with a DSM pressure plate...

Yep, that appears to be the case! I will just have to find someone other than ACT to sell me such disc, because they do not list it. I suppose, I can ask them

I am told by another 4g63 mightymax owner that his clutch is holding up very nicely and he couldn't be happier with it. He got his from http://www.specclutch.com/
His name is David and he goes by "TruckA" in this forum, I am surprised he hasn't chimed in on this.
On another note, in the next day or two, I will hopefully have a chance to try out my FWD DSM flywheel, mightymax clutch disc and DSM Pressure Plate setup. It definitely isn't the best looking thing I have ever assembled, but it *might work better than my stock mightymax clutch/flywheel/pressure plate. I will be sure to post the results and things progress.

hey guys just trying to sort out my flywheel clutch setup for my narrow block engine with a d50 km-132 tranny

whats the best option for getting a decnet clutch setup on there, im running an narrowblock motor with a big16g turbo and hoping for 200kw at the wheels

d50 flywheel with a clutch, pressure plate etc to match from the same model seems the easiest option?they are 215mm diameter arent they?

are the fwd flywheels the same size as the rwd ones? you guys are talking about mixing and matching flywheel, clutches and pressure plates between the mighty max and fwd options so i assume they are all the same size?and interchangeable
what is the advantage of going to a fwd flywheel and having a bearing hole machined into it?or are they just easier to find than mightymax ones?

I've got a Centerforce dual friction clutch. It's a 225mm clutchkit from a Starion non turbo.

Check the Centerforce site for more info.

I'm very happy with it.

hey guys have ended up with two flywheels sitting here

one measures 265mm across the other is 285mm across

which one do i use with the narrow block engine and gbox combo?
i assume the 265mm
just want to check

AWESOME FIND! Looks like NT and turbo 86/87 Starions had the same disc! Now, I just have to check if it will work with DSM ACT pressure plate

I'm sorry, non turbo should be non I/C! My bad!

This just opened up huge number of easy clutch disc options for me!

I think that I will get the car to work on a simple clutch disc from the Advance Autopart with ACT 2100 PP. Later on, I might get a better disc.

But I spent many hours unsuccessfully looking for some application under Mazda, Toyota and Nissan that would use 225mm/23spline disc. And didn't see the obvious choice, right under my nose
