Un-related but...
Top end;
The 1600 head is flat, with no combustion chamber, a bit like a moden diesel. I had the biggest valves I could get in there, multi angled seats, soild lifters, the valve stem guides removed from the inlet tracks, the inlet and exhaust tracks reworked, polished and ported and port matched to the manifolds, 4-1 magnex full system, sounds good, but too boomy on the motoryway. The standard inlet manifold modifed to accept the big 20v 5cyl audi throttle butterflies, the 5th injector removed, and blanked off, along with the cold start valves etc, (as I moved the servo to infront of the driver) down side, it runs like a bag of sh1t until it's warm, 1800 injectors, 1600 metering head (higher flow rate) vw motorsport alloy air box, external cone filter. The fuel pressure regulator was a 2.2 20v vacuum adjustable untit, but it made little difference to out right performance, but drank fuel like it was going out of fashion.
Bottom end;
Had the block surface ground, increasing compression with out ruining the combustion chamber shape.
New max oversize pistons, fully lightened and balanced bottom end, including the flywheel/clutch assembely & bottom pullys, re-ground crank and new shells.
Gearbox;
Orignal FM code close ration 5 speed box rebuilt by me, with a very short shift kit, which leads me on to a little problem...
I have 4 bent exhaust valves and 4 marked pistons, after a break down in communications between my brain and left arm. Max revs in 4th (7500rpm, may have been closer to 7750rpm) and slipped her into 3rd instead of 5th, the clutch was up for less than 1/2 a second, but the damage was done, I was very luck and still very pissed off, as that was June, and I still haven't got the time or funds to sort it
But she will fly again, flat out is quite scary (obviously on an empty de-ristricted road in good weather etc etc...) and sound like it is going to blow apart, reving at just under 6750rpm, the shape of the car won't allow it to go any faster without a sh1t load more power...
