For the boffins ; replacement clutch advice needed

Hi ,
appreciate some advice on what clutch you would recommend for my 93 WRX .
The cars fitted with a six speed close ratio JDM gearbox and has ,I believe , the six speed flywheel fitted to my engine .
Torque output on the very young 2.5 built engine at the time was measured at Motoscope at 400 lbft /385 bhp a couple of years ago. Might be slightly less now unless I've just got used to it .

Bearing in mind possible future turbo upgrades what clutch is good for 450/450 and what would this cost ? Generally I'm fairly mechanically sympathetic .

I have been told that a standard six speed clutch is good for 400/400 and is very durable.

Could I machine the flywheel to increase the clamping loads from the clutch plate and increase the torque rating ?

Paddle clutches are not an option as it needs to be kind to my driving skills.

Cheers,
John

Stick with the standard Exedy clutch.

machining the flywheel does not increase the clamping force it only alters the angle, the pressure is dtermined by the sprung plate, a standard 6 speed clutch (genuine exedy) will take 400lbft, an ap racing 6 speed clutch will take 500lbft and feel n drive like a standard clutch, exedy pink box will handle similar but sometimes clutch judder is noticable

Thanks Andy and Kushbex,

just the information I need .

Best regards

John

I ran a standard clutch with 500lb/ft for 9 months before it went bang on the rollers, I have a sachs clutch fitted now and it feels no different than a standard clutch. Excellent clutch and good choice by Mr Kindon who fitted it

Thanks for the reply Iddy,

Some motor you've got there . Very nice .

Do you remember where you bought the clutch from or did Andy both supply and fit ?

John

Thanks about the car.

Andy, supplied and fitted it.

sachs racing clutch is identical to ap racing clutch just in a different box
