Default 2.15 Stroker P1 Project

Thought i might start up a project thread on here so people have a vague idea who i am when i finally make it to some meets once this is finished!

You guys made me very welcome and I have some interesting shot of the build process so thought it might be nice to share.

Car started smoking one morning on cold start so it got taken to Chris Palmer Auto's in Bristol for Spencer to take a look at. They found masses of petrol in the sump. 600 hydro carbons to be precise! Told this would normally be below 100. The cause it still unknown until my engine is stripped down but look like piston 4 has an issue –

Compression Test Results: Pistons 1-3 = 155-160psi, but number 4 down to 135psi.
Leak Down Test Results: 1-3 = 10-15% but number 4 = 22%.
Spark plugs: 1-3 were black where it had been running lean and number 4 had a fine glaze of oil over it.
There was a small amount of tiny swarf particles found in the sump.
Bores and top of pistons and valves etc look of with the camera (although he can’t seen them too well with the camera) but it’s feared the side of the piston might be where the issue lies, and the small bits of swarf could have blocked but the oil pump cause the loss in pressure.


So anywho I had to make a decision and after about a month of research bugging the hell out of other specialists, mappers, and Techy gurus I opted to go for a 2.1 Stroker Kit, capable of 550bhp. I only wanted to rebuild once and didn’t want to be restricted by the build spec, this is what we decided on:
