Tranny Headaches

[wishIhadaturbo]

I have a 92 NT. Does it have the one piece flywheel pressure plate combo ???

If so, is there any reason I can't buy a turbo flywheel a perfomance clutch kit and bolt it onto the turbo engine and have it mate with the non-turbo 5 spd ???

If it will work is there anyone looking to sell a stock flywheel cheap ???

TIA

As far as I know there are no 1 piece flywheel/pressureplates. If there was how would you get to the bolts that hold on the flywheel? As far as the upgrade, the spline counts on the input shaft of the tranny and the clutcth disc would have to be the same and the diamiter would have to be the same to fit together. I dout that mitsu used the same input shaft but it's posible. Then the diamiter of the flywheel must be the same as the n/t flywheel for the starter to be able to properly engage the ring gear. In witch case you could just bolt a proformance clutch right to your flywheel. Chances are they arn't the same, or a lot of n/t guy would be doing this. Chances of this working in my opinoin are less the .01% since there arn't a lot of n't guy doing it already. And not to be insulting or anything, but how much Hp are you planing on getting out of that n/t to make an upgraded clutch nessary?

I actually just rebuilt an automatic DSM Tranny lastnight for one of my friends. He also has an NT that he's selling..so..we're trying to get it back together. There is no pressure plate so to speak. However the flywheel and the torque converter are all one unit that has 3 bolts that attach to the engine. IN order to get a 5 spd to fit to this engine you will need to purchase a flywheel, clutch kit, Clutch Master Cylinder, Slave Cylinder w/ fluid line, Clutch pedal assembly, shifter, shifter cables, console trim for 5spd manual, tranny, maybe the axle shafts (Don't know if they're different) and possibly an ECM ( I am REALLY not sure about the ECM) I'm sure i've forgotten a few things but be sure to check the VFAQ because I'm positive that someone there has done this before. There will probably be some major differences in the wiring harness, I honestly can't tell you that a DSM wiring harness is universal with all models and variations. Total cost will bring you to about 3,000.00 even with used parts, and about 18 hours of labor (again guessing). Basically the price of a somewhat rough around the edges used Turbo 1G AWD DSM.

Best of luck with your project

It's simpler that that. I am not changing transmisions, I bought a 92 GST for cheap and am changing my 92 GS NA engine with it's turbo engine. The car it came out of is an automatic. The main question I have is the flywheel/pressure plate I have in my 5 spd GS the modular or is it the 215 mm ? I am trying to find out so I can have everything here, as both of the cars will be down and I won't have a ride anywhere for anything.

BTW I noticed you were in Springfield Zero. Hello from Dayton.

Wow you are close. Okay..either I really misunderstood your first posted question or it was the way the question was phrased. If you are changing engines and you are needing to know if the tranny is the same then just look at the DSM plate on the firewall. It identifies the transmission in your GS, now match that up with the turbo model. Chances are they are not the same on the inside, but probably exact on the outside. Last I was informed the GS NT tranny actually had gearing that was more beneficial to the Turbo model that the original turbo tranny. Wether the splines will fit or not...::shrugs:on't know.

What you have in your GS is a Torque Converter with the flywheel integrated into the torque converter (One inseperable piece). Attached to the engine is a 3 bolt driveplate that bolts to the torque converter from underneath the car at the flywheel inspection plate.

Best of luck

By the way! This only applies if you have an F4A22 Transmission! The others are 4 bolt. Either way the only thing you will have to change is the torque converter and the driveplate from the donor car and put them on your GS.

I just finished this exact project. Ket me know if you need any help if you haven't finshed this project yet. On my 92 NT I had to use the NT pressure plate and throw out. The turbo car I bought is an automatic.

I'm not sure about the 1G's but the 2G 420a motor's trasmission comes with a modular clutch, which has a special flywheel as a part of the unit, and the clutch plate and pressure plate are built together. If you replace the clutch or the flywheel you have to replace the other, unless just buying a factory modular clutch replacement (which they normally come with the flyhwheel part anyways).

If so, is there any reason I can't buy a turbo flywheel a perfomance clutch kit and bolt it onto the turbo engine and have it mate with the non-turbo 5 spd ???

The turbo flywheel will not fit into the non-turbo tranny's bellhousing. Just buy a non-turbo flywheel (by findanza, clutchmasters, ect...) and clutch (clutchmasters, ect...) to go with it.
