all TQ figures I'll ever state are at the wheels, since we dyno at the wheels and dont typically pull the motor to do so.

I hate to be retardedly redundant, but stage 1 as in this feller here...

If it holds till rod breaking territory then slips and still drives mostly stock, I think I might like that thing. Seems a cheap choice with my stock FW...

Not sure if it was a 1.8L or 1.6L clutch but I always recommend putting in a 1.8L sized clutch anyway--it will always hold more TQ all other things being equal.

It's $310 from the same seller. The FM STG1 is $350. and the ACT ZM2-HDSS is $460.

Dont see the 949 on their website anymore.

My car's previous owner had a 1.8 flywheel with oem clutch on my 1.6L JRSC, it lasted about 10000 miles and it started slipping. That was at 8psi

I need me a 1.8 FW still I guess. Ebay lists the 1.6 stage 1 at 210ftlbs, but everywhere else is 130ftlbs or so...

Getting back to FM prices again, may as well just do it right I guess.

Yes do the clutch the right way, mostly because it is a PITA to pull the trans and replace the clutch after you go cheap and then something ***** up.

When you go from a 200mm ACT HD to a 215mm the TQ load goes from 195 to 245. That's about 20% better with the same level PP and clutch disc.

here's directly from Exedy:

a 20% increase in TQ as well.

I just wouldn't use a 1.6L sized clutch for boost unless you get a super heavy PP with higher clamping loads. If you look at the difference in the diaphragm springs, it's apparent why:

teeny tiny:

large and in charge:

The light weight FX 4140 CHROMOLY FLYWHEEL is worth it. I have been running one with a 949 sport clutch for a month now and don't have any complaints. I would not cheap out on the clucth kit, but the flywheel works.

I'd like a light flywheel, and I'd order a ebay one, but I'm still thinking about trying to find a cheap stock 1.8 wheel. ~$400 bucks with the FM stage 1, hopefully.

I have the lightweight chromoly f1 flywheel and track the **** out of it with no complaints. It's very easy to DD as well. It's one of the best mod I've done.

The new 1.8 flywheel is bolt on direct on 1.6 models?

Any problem with the starter or gearbox case?
