Flywheel questions.

[Maverick4g63]

Im in the process of replacing my toasted 6 bolt for a porters performance 6 bolt long block. Im needing advice on whether I should have my original flywheel resurfaced or go ahead and spring for a new lightweight alternative. I have read about guys having problems with their machinist not cutting the step height correct. Would someone please elaborate on this for me? I have tried searching for this without much luck. Tapatalk is a bit quirky.

Here is Road Race Engineerings instructions on how to properly step the flywheel.

Thanks. Has anyone done a comparitive article on the performance gains going from oem to an aluminum flywheel.

As with any vehicle there are similar things to take in to consideration. Too light of a flywheel you will loose ease of drivability. Too heavy it is a slow revving engine. Personally I would go with a light weight steel flywheel (act streetlite or rre's no name). Make sure you check for cracks if you plan on lightening/resurfacing your stock flywheel.

Driveability is not an issue. I was leaning towards act's aluminum wheel. On a different note, my water pipe was corroded on my 6 bolt. My question is this: will I use a 1g water pipe or a 2g water pipe? I bought this 98 gs-t spyder from a guy who had good intentions but no game plan. Im having a hard time identifying which components he mixed and matched from the 6 bolt swap. The CAS harness is a nightmare hack job so im looking into finding a new connector for it. New dsm'er needing guidance...

Chromolly is better than alluminum. It will stand up to more hp.

I've never had drivability issues with my aluminum flywheel. Using a light flywheel decreases the amount of mass of the rotating assembly on the motor which results in less drivetrain loss equaling more horsepower. In almost every case you are guaranteed to gain at least a little bit of power. If you have your OEM flywheel off and it needs resurfacing, I would go ahead and replace it with an aluminum one or something analogous to it.

I appreciate the input. I ordered the ACT Xact flywheel yesterday after reading so many posts about having trouble getting that step height exactly right. That all sounded like trouble to me as I have poor luck with such endeavors.
