Needing an uprated clutch for my K series

Looking through Microcat earlier today, it would seem that the K + L-Series engines share the same clutch assembly.

So, before splashing out on an expensive uprated one, what is the standard clutch rated to?
If it's good enough for a fairly torquey L-series, it should be good enough (I Hope) for what I have planned
 
I got HD clutch for PG1 gearbox /L-series engine - GEN Land Rover stuff :) . It's a little bit wider and got different springs.

You also can go to cgclutch guys - they got full range of custom clutches. also Black Diamond got some.

The standard clutch will take well over 180 ftlb of torque. No K4 makes anything like that much torque. Even a KV6 needs to be modified to make that much torque.
 
Just checked, the L-Series only has 155LbFt? Seems rather low for a turbo diesel...

Tell me more about his HD clutch though.
The part numbers I get are UQB500010 for the clutch plate, and URB000070 for the cover...

210nm is quite usual for that design of engine with that capacity.

besides a quick mod to the fuel pump etc and its way higher (cheers rover ron for mine!)

I will be aiming for 200bhp, and 200LbFt (265Nm-ish)

Just need to know the clutch will be upto the job before putting it all back together

200 ftlb from a K series!!?? :eek:
I hope you don't want it as a daily driver.
The clutch should take it. The engine might not.
 


This Rover 75 is kindly donating its 1.8 Turbo lump, ready to be dropped into a Freelander with a 1.8 with HGF

150bhp + 160LbFt as standard.
205Bhp + 199LbFt with a remap

And it will be a daily driver :)

Be careful and make sure the cooling system is spot on. The liners are going to take one hell of a pounding at that power level.
Whilst I love the K series and tuned many including my VVC MGF, I'm well aware of its limitations.

Caution is advised.
The turbo K series is the most likely to suffer catastrophic HGF, most likely caused by liner movement.
I can see the appeal, having just driven a 1.8. It's seriously lacking pace compared to my V6.
 
The car has already had the MLS gasket fitted by the previous owner. I had a spare head set in the shed, as it was always the plan to do it before fitting. No point in doing it twice though.

Car was thoroughly tested for overheating on the drive home ;)

The 75 rad appears to be around half the size of the Freelander rad, so that can only help things

The Freelander was bought as a runaround for the wife originally, until she decided she wanted a 5 door, so I thought I would turbo it, and turn it into a company demo.
Since buying her a TD4, she has decided she would prefer the 3 door now, with a turbo :rolleyes:
