Porsche V8 for your teener, For sale in Seattle Options

[PanelBilly]

Saw a 928 engine for sale on Craigslist last night if anyone out there was thinking of doing a conversion. It was only $700 and looked complete. I'm very tempted but with a small garage and things yet to finish on my car, I'm going to pass on it

[rick 918-S]

The standard US 4.5-4.7 version is around 218 HP. You can get that from a Subi. My suggestion for anyone wanting to try this is to get either a US 4.7S (310 hp) or a 5.0 32 valve engine. The other option is to combine the 4.7 euro spec S engine which is what I started with. This engine is factor rated at 300 hp. The blocks are made of solid Alusil. The lower half split at the crank line like a formula One engine. Very cool.
The only pistons you can run (unless you install liners) are factory pistons. They have a special iron coating to run in the Alusil bores without galling. I had a block bored and used 32 valve 5.0 pistons re-notched for 16 valve euro heads. This is known as a Hybrid. The 928 guys that have done this and dyno tested their cars (turning PS, AC, Alt, clutch fan, etc.) are over 350hp. I'm turning an alternator. Everything 928 is held close to the breast and expensive. a core set of rebuilding euro heads are 1k. The have larger ports and bigger valve and a better combustion chamber shape. A set of used euro cams are $ 500.00 if you can find them. The profile is about as steep as you can run with CIS without fighting the sensor plate action. The euro intake has a larger inside diameter and the throttle body is way bigger. I think I remember the last gasket set I purchased was $ 800.00 (IMG:style_emoticons/default/confused24.gif) No one makes any conversion parts. I made all my own stuff including shortening the transaxle. (IMG:style_emoticons/default/sawzall-smiley.gif)

In short it's not for the faint of heart.
