It was a previous owner modification, probably the only good thing he did for the car. When I put it back to the original colour it will be totally de-badged, I like the clean look. _________________ 1987 951 - M193 Version for Japan |

Chrenan, did you have Eurorace do any porting, or was it simply the valve work and assembly of the head?
Also, on your Audi 5000 big bore throttle body, have you had any longevity issues with the fitment of the stock 924 rubber boot that mounts directly to the TB? _________________ erstwhile owner of just about every 924 variant ever made |

Awesome!
Shame it's hidden in the engine bay!
did you skim the block to up the CR any?
I had a big audi TB, while the intake pipe was a squeeze it was perfectly adequate and suffered no ill effects from being stretched over.. _________________ 1994 Lotus Esprit S4 - Work in progress...

Nope, didn't skim the block at all. It was a fairly mild build. I'm happy with how it turned out, still running strong, pulls really well.
I still have the engine that came out of the car, so when I have the time and inlcination, that one will be bored out, stroker crank, custom pistons and either another big valve head or a 931 head. _________________ 1987 951 - M193 Version for Japan |

Ports were hogged open as well I believe, not actually sure, old school 80's techniques .
The same rubber boot has been on since the engine went together, it was new on installation and shows no adverse wear from the larger throttle body. _________________ 1987 951 - M193 Version for Japan |

Any plans in place to get it dyno'd? I know I for one would love to see what kind of power it makes. I am a bit on the biased side of that having worked closely with the owner of dynoplus (engine dyno only) and being friends with the owner of SCP (engine and two wheel chassis dyno) here in Calgary.

No plans to get it dynoed, but it would be interesting. I'd have to find a dyno that reads that low! _________________ 1987 951 - M193 Version for Japan |

Oh i'm sure it'd be no problem, if they can find out the power of a smart car then i'm sure they can find out what power yours makes. Personally I'm not interested in the HP from your engine, I wana see the torque #s that It produces.

Hi Chrenan
Really great pictures, i was looking at the exhaust ports on your new big valve head and it seemed to me that they had been enlarged and rounded off. I also noticed that you appeared to use a stock exhaust manifold (i think you call them headers in the US), could you tell me what gaskets you used and if you did anything to them to match the ports?
