Porschevy Engine ?, never thought this was possible Options

[yarin]

2.0L case
2.0L heads
Chevy V8 pistons and cylinders (105mm)
2.5L final displacement
8-8.5:1 compression
P&P, 3 angle.

Has anyone ever heard of a Type IV with mixed components like this?

This means the engine wasn't stroked, only bored. I'm assuming with a thicker cylinder wall heat dissipation won't be as bad as an original bore only 2.5l type IV.

Comments? http://www.strictlyvw.com/ built this engine. I know that a LOT of machining must have gone into this.

I wish this topic came up a week ago. I just traded off an engine I've had for a couple years. It was a 2580 type 4, had a stock case, opened up to accommodate larger pistons, 1.8L heads ported and polished with 38mm exhaust and 48mm Intake valves, 76mm stroke on a stock 2.0L crank that was reworked and fully counterweighted, 104 or 105mm TRW forged chevy 350 pistons in Biral (forged aluminum finned) cylinders. It ran with dual weber 44's. I know it was built some time ago, and when I got it, it ran, but needed a rod bearing, so I disassembled it and put everything into boxes awaiting a rebuild. The crank and rod setup were a bit crude. The rods were stock 2.0L that were ground at the base for clearance, all the way up into the rod bolts, and a substantial amount was taken out of the bolt heads for clearance. Didn't look pretty at all.
Of course everyone knows that a big type 4 can cost $6-7K easily, so I thought I hit the jackpot, but the more I saw the stuff from Raby’s Aircooled Technology and other high end builders I doubted the integrity of the engine. It should have produced around 200hp easily. I’m a bit of a perfectionist and that got the better of me, I traded it off for a few boxes of nice 914 stuff like seals, lenses, mirrors, a set of old weber 40’s, and such a few days ago. After doing the math, I probably didn’t come out that great, I’d guess around $1200-1500. In hindsight, I should have kept the case, cylinders, heads, and carbs, got a new crank and rods and properly clearanced the case. Then I would have had a pretty nice engine for around $3000 based on the value of what I traded it off for. Such is life. I don’t know if that helps you much, but at least it does confirm that such things exist. Good luck. (IMG:style_emoticons/default/wacko.gif)
