As for the rebuild i am buying a shed today and a work bench and all of the work i will be carrying out myself. The big end bearings have definately gone, as have the camshaft bearings, so these will be replaced, but im not sure if i want the cylinders rebored. Is it advisable to do this while the engine is stripped? Also grinding the crank? I pretty much want to take the engine apart, uprate whats knackered, replace all the essentials and put it back to together. Im a bit old hat when it comes to ignition but i have been reading up on wasted spark ignition and it does sound bloody good! Are there any disadvantages to it?
Sounds like the car has already got some of the bits you need for more power. What turbo is it ? If the bores have no signs of lips or marks and they measure within the tolerance there will be no need for a rebore. With regards the crank, if as you say the big ends are knackered it will be unlikely the crank has not suffered any wear, but again it needs to be properly checked.Most people would probably do everything to make sure of no future problems and remember if you are going for more power the engine needs to be 100%.
I have had no problems with the wasted spark ignition system myself and cant see there are any disadvantages to it.
