Yup and thats why i dont want to have to dump the one i have.

After brain storming for a few hours what about heat treating just asking i have read a bunch of good reviews about it.

....Are you referring to the automatic counterweight, which is about $35 or so to pick up? 'Cause that's really all that is needed in an aftermarket flywheel. Which the OP should already have anyways.

Plus it's no problem using an N/A flywheel/clutch on a turbo tranny, it's just less surface area on the clutch.

Both methods your asking about will make the gears stronger, but also more brittle *If that makes sense*

Dude you can look for loop holes and try to convince yourself that these "treatments" will strengthen your transmission, but at the end of the day its still a weak POS and your motor/setup makes more power than it can even dream of being able to handle.

So you can do it right now or do it right later. Either way you'll have to pony up for something that has superior tooth design and ratios that can handle big power/torque.

You remind me of me when I was looking for a cheap ecu method for my nb
I kept trying to convince myself that fpr's, voodoo boxes, and other band aid bullshit will "get the job done".

In the end I purchased an adaptronic.

I have everything for the flywheel and clutch but the rx7 turbo tranny and NA rx7 tranny have different splines and sizes. Also the NA clutch disk size is smaller then a turbo clutch disk.

I was just trying to cover all the grounds and wanted to get all the opinion from the smart people here on MT.NET. =]

So the question now is should i do a RX7 turbo trans or should i try and make a 6 speed miata trans works.

It would be purely preference. I don't know the Tq ratings between the two. I would just do the easier one.

Depending on the brand of flywheel you could pay 600 to 400 for a flywheel and counterweight. act sells the counter weight by its self for $230 bucks then there cheapest flywheel is $308.

So i went on summitracings wonderful website and i put in the disk size i need 224mm and put in the turbo rx7 fc tranny 23 spline 1.031" shaft diameter. As funny as it sound the disk that came up is the one off a 2.0l miata take a look.

Do you guys think it will work if i run that disk and a NA pressure plate. This would be to run a rx7 turbo 2 tranny.

miatamike203

YEAH so it looks like im going to go with a TURBOII tranny. I just talked with ACT and they said i should have no problem running that disk with my NA flywheel and pressure plate. So now i need to find a turbo 2 tranny.

Now i need to see what the drive shaft fitment is going to be.

Drive shaft should be cake. Find a drive shaft shop. Most decent sized cities have one. Tell them what flanges to put on each end and your golden. We just had one at work made for a jericho transmission with a mustang cobra diff. Took them three days, two of which were spent waiting on the shaft for the jericho.

If driveshaft fitment is the hard part of a swap, that's a damn easy swap.

miatamike203

Im not too worried about the drive shaft i also know a few places to have it done. I was worried about the starter bolting up and working turns out it will. Now just to get all the stuff and make it happen.
