Unfortunately my engine seems to have gone bang at a rolling road session. The tuning guy was revving the engine and he detected detonation. Reduced the boost by 0.1bar and still no high revs. Then big puff of dark smoke from the n/s exhaust and would not rev past 4000rpm. Jeff took out the plugs and 5 of them had no top metal bar. New plugs in and the engine was idling really lumpy and ticking badly too. I have taken the car to get the compression tested but it looks like some damage up top. Assuming the head needs to come off and some work has to happen - what are my options for more performance on the rebuild?

Car is great. The new engine is sooooo much smoother than the old one. Pulls better from low revs too. Keeping my boost at 14.5psi until the new intercoolers arrive and then get it tuned and set up by SE Nissan.

A very happy man see you all at either Supercar Sunday at Gaydon (Sunday) or JAE @ Billing (2wks).

 

Nice one John,They set mine up 18months ago and I never had a problem since.
