1.8 VVT Turboed at 200 whp; stock clutch?
 
Hi,

I was told a stock 1.8 clutch can hod the torque required for my 200 whp VVT plans. But what is stock, and I have my doubts on whether it will hold that torque. Please recommend from experience.

Cheers,

Hugo

Might hold long enough to get out of your driveway. Might.

Buy a stronger clutch.

9 Clutch

If you're going to run over 6psi, chances are the OEM clutch will start to slip. A clutch rated at 200 ft lbs. of torque should be able to hold to around 9-12psi. A clutch rated at 260 ft lbs. of torque should hold against everything you throw at it, within reason. There are a number of manufacturers that sell clutch kits.

Typically a kit includes the Pressure Plate, Clutch Disc, Throw-out Bearing and Pilot Bearing. You’ll want to replace all of these when upgrading your clutch. Surfacing/replacing/light-weighting your flywheel would also be beneficial at this time while it can be removed. 1.6L Miatas can upgrade to the 1.8L clutch when coupled with a 1.8L flywheel.
