Title: Ready to play "Lets id this engine" again?

thats the engine in question. it looks very VW/Audi to me. but the intake ports are not on the same side as the exhaust. and the oiling system is on the exhaust side of the engine also, like a 5 cyl vw engine. it doesnt have a cam, but it looks like it is the same setup as a VW head, also has 8 threaded holes for holding the valve cover on. oil pressure sender on the back of the head. engine mount in picture looks like the kind that are in my audi. front pulley looks like some crappy stamped steel vw/audi one also.

ok, so i talked to the owner, and its an audi engine, but what the hell is it? how big? and where does the intake go?

also, what kinda block is this? i wasnt aware that vw made an engine with oval pistons.

Could be a Mercedes engine. They turboed stuff way back.

for 50 bones buy it, and find out.  Has to be worth more than that to a builder, and maybe the turbo will be useful, or you could just e-mail the guy and ask for better pictures.  Can't use the engine, no oil pan, prolly no rot. assy. and no cam/ cam cover.  I guess its an early water cooled porsche engine.

If its an Audi, then its a LS100 engine which was used in the Porsche 924? They were a cross flow design.
The turbo and manifold look very strage though.

I'm pretty sure it's a 2.0 litre Porsche 924 turbo engine (early '80s).  That funny looking plate on the turbo is a built-in pop-off valve.  That output flange on the turbo bolts on to a cross-over pipe that runs across the valve cover.  Really not a bad engine, but tons of turbo lag (big 'triple K' turbo).  Does not tolerate too much boost very well (e.g. broken rings, blown head gaskets - BTDT).  Based on a VW/Audi design.  Should mount up to pretty much any Audi 5-cylinder-style transmission.  160 HP stock in US, about 220 HP in European trim (intercooler).  The GTR and GTS 924s where making somewhere around 400HP with this basic design.  I don't really know what they're worth these days.  20 years ago a good runner would fetch $1500.

Didn't Honda spend a fortune on proving the benefits of oval pistons before? This is why we all use them today! ;D

Think honda tried them on motorcycles and such too. probably pricey to machine for production and impossible for avg joe to rebuild ie hone or bore. Interesting concept. gotta keep mind open for new ideas yet understand KISS

Honda did pioneer ovals in GP bikes...as I recall, it was a matter of trying to get rings to seat that destroyed the whole idea.

there were a number of two stroke mopeds from europe in the 70's that had oval pistons, apparently helped make wider ports without having the rings bulge out into them so bad.

they were not made for long though, so its hard to say wether or not it was worth the extra manufacturing expense or not.

the rings were 2 piece. and there was 2 flat sides on the pistons. 8 valves per cylinder. 2 spark bolts per cylinder.
