I am building either a 2.4 or a 2.7 type four and am wondering at what point do I start having to worry about needed something more than just the stock 2.0 liter type 4 sachs stock clutch? I know it probably depends on the cam and the amount headwork done but really can I get away with building a 2.7 with mild to fair amount of porting and abit larger valves? and obviously a sport cam. will I be seeing a lot of slippage? And Will something as simple as a particular plate help? thanks,Jo

With the old 4 springs you have to be very careful about the spring to flywheel bolt spacing. You basically can only have one cut on the flywheel before you have issues with even with ground down bolts.
BTDT I had a new NOS 4 spring as well. Likely one of the reasons why they fell out of favour so fast. |
