The engine damage! May 28, 2016August 13, 2016 admin The prior damage turned out to be slightly more than anticipated, chunks of forged pistons missing and you can see in to the bore! This is down to detonation and was showing on all 4 cylinders (this one the worst). I think the rods, crank and cams are about the only stuff moving in to the new rebuild. Still the rest of the rebuild stuff has turned up, however it’s costing more because the detonation damage has taken out my original head and Supertech valves. Still I’ve got some decent prices off Engine Dynamics including another set of Supertech’s, so it shouldn’t be long before I can take the car to mapped properly at Ray West Tuning.
