   hello lads, i would like to know what clutch kit should i go.
   
   i want something that can hold 300ftlbs
   i do not want twin plate clutch.
   ive read that if i go 184mm single plate clutch ( ap/helix) ill have to get flywheel machined...
   
   then is it possible to hold 300ftlbs with a plug n play plate that goes on the oem 200mm flywhell ? if yes, wich one and wich disc (i want damper disc so i can go sweet on)
   
   thanks

   yes its technically possible to have a 184mm plate to take 300lbsft ,but not in a sprung plate and then your cable would not be strong enough to lift it
   add to that the load on the crank thrusts --not a good idea
   you are also getting to the edge of what the std size splines can take ,
   there are solutions but not cheap

   found ap racing 4 paddle sprung CP4814 rated 250lbft (on ap website)
   and helix plate cover 60-3862 for a really cheap price
   
   ill give it a try

   I spoke to Helix a while ago for my turbo needs and they couldn't do anything.
   
   An MA box has no hope of holding together with 300lb-ft anyway so if you really are looking to make that much torque you'll need a suitable 'box and that will most likely have a different spline. It will also most likely have a concentric hydraulic slave so that may solve your clutch pressure problem, if not the crank thrust potential problems.

   not a chance in hell of that cover holding that torque+ its the cover that is final decider of how much torque that can be clamped by the pressure from the cover --if using that you might as well use the plate that is meant to go with that cover --but 6 paddle for more wear life
   that cover is rated at 162lbft which equates to about 220bhp tops --less if power is made at lower than std rpm --which it will be with a turbo --just pray for lots of wheel spin so clutch never sees real power being produced
