clutch recommendation

[cmcfaul]

Stock 89, G50, turbo look Carrera. Plan on replacing the clutch with turbo installation. If no surprises, plan on adding a thicker cylinder shim gasket, new ARP Rod bolts, Rings and .5 bar turbo with IC. With this modest increase in power, is the stock clutch replacement adequate?

Thanks,

If you plan to turbocharge it, definitely upgrade your clutch. My stock 964 clutch only held 3-4psi before slipping so like 0.25 bar

Get a sachs sport clutch with the turbo pressure plate. I went lightweight flywheel with mine and replaced the dual mass but I think yours is already a single mass.

I’ve been very happy with my Kennedy clutch after over 10 years. I’d avoid Centerforce on a turbo engine.

Stock clutch will hold .5 just fine if it’s healthy. And THAT is IF you can stay at .5 bar. Once you get a taste of boost..... you want more!!!!

KEP G50 Stage I will work like a champ. Save some weight and lag.

Sounds like I will need something a bit more than stock as I can see pushing the .5 bar up a bit. as i will have an IC and slightly lowered CR. I just know I will do it.

This is applicable to the 1990-98 models, not the 1989 G50.

The stock pressure plate *might* hold if healthy, but the sure bet is a Kennedy Stage-1 with a new 930 spring hub clutch disc.

Thanks Chris,

Is the setup you describe a thigh master...is it much stiffer than normal? My left knee has some miles on it and not getting any younger.

I am happy with my KEP stage 1.

It's not terrible, but definitely a little more firm than the pedal effort with the factory clutch.
Still very driveable, not an on/off switch, thanks to the spring hub and high friction lining.
Call or email for a quote on all parts.

I'd say my Kennedy stage 1 clutch is stiffer than my stock Cayman clutch on the same order of magnitude that the Cayman clutch is stiffer than a Honda Civic clutch. Yes it's stiffer but it's not too stiff even for occasional stop and go driving.
