Shouldn't the aftermarket flywheel come with its own bolts? If not, as long as the threads are the same you can reuse the bolts off of your NA pressure plate/flywheel.

i thought the NA flywheel and pressure plates dont fit a t2 tranny? you have to use a t2 clutch and flywheel pressure plate to fit a t2 tranny.

Correct sir. I think you also need to either get a modified driveshaft or swap to a S4 TII rear end. I don't think the N/A driveshaft hooks into the turbo tranny correctly.

Correct.

To answer the OP, No, you cannot re-use all of the bolts. There are indeed 2 of the bolts that are different. Don't try, you will end up effing up the threads like I did.

Either source those bolts from the forum or step up to fancy new bolts, they aren't much.

Mazdatrix gets their parts from Mazda, so take your pick. It'll be easier to just order them at the dealership since you won't have to pay $10 shipping on $2 worth of bolts.

you can get the bolts at the Dealer or go to a hardware or Auto parts store and get Hardened steel Metric bolts to connect the Flywheel to counterweight,That is what I am running,and some of them were a Bit long,but nothing a Dremel tool with cut-off wheel couldn't fix!.cheers.

Your car will do better with a stock weight flywheel vs a lite weight one.

The car will be quicker and faster, than any lite flywheel fitted car..

Don't spend money to go slower..

Use loctite on the flywheel and pressure plate bolts

I would install a driveshaft loop & a scatter sheild.. Its not a good time when the u-joints come loose up front, or your flywheel cuts your legs off.

It's been stated over and over again by most flywheel manufacturers, but lightened flywheels don't make the car produce more power. A lightened flywheel just makes the car have better throttle response.

It depends if the driveshaft is an auto or manual. automatic shafts are shorter.

OMG!!!! Are you telling me that a modification that doesn't directly effect the engine doesn't make it produce more power!! I am startled!!!

However, thanks to the laws of Physics, lightweight flywheels actually do increase the amount of available power, however much you want to deny it.

Secondly, glhs said that a lightweight flywheel makes the car slower and I asked him to prove that. If you would like you can prove that a heavier flywheel will make the car go faster.

well im not doing stock s4 t2 flywheel cause its heavy. and a stock flywheel vs a lite flywheel, the lite flywheel would win in a stock car or any car, its less drag on the motor to move it, the same thing if you lighten the car if you remove all interior, you be quicker down the track, so if you lighten the flywheel you'll will have more power useable to make it down the track so better times etc...,and i wont need a scatter sheild if it pass 13,000 rpms which i wont be, it also dont make power after 8000 on stock ports

and glhs0867 ; im stilling waiting for that video of your car running 14.2 on stock ports


and dkwasherexd ; its cool

Ehh, from what I gather you should use a scatter shield over 8500. Besides, its your legs were talking about. Plus my clutch and flywheel specifically give a 8500 as a maximum without more protection number.
