heavy fuel

Wait, this has already been done:

well ok, so it was a Rabbit and there was some level of fab skills required. But we're talkin big picture conceptual stuff here..........

On the same scale, my LS2 weighed 156lbs less than a 928 S4 motor. Stock for stock, the LS2 produces 80 more hp and torque. Weight distribution alone is enough reason to bother.

Sure, It's always good to see 928 guys chiming in. Especially on topics like this.

Do you know how wide the 928 engine is? If it's too wide by only a couple cm then maybe a quick & dirty hack up of the shock towers, and a flat plate welded in, could provide some clearance. I've seen similar things done to 80s-90s VWs where they swap in the VR6 motor.

soon i should be able to get back onto my project '83 928S. ill do some measurements then and see if it will physically fit in the engine bay, hookup points etc notwithstanding.

IIRC it's not even close. None of my 928 engines (or cars) are home so I cannot go out and measure one.

The 928 engine is the same size overall as a 502 chevy big block except the 928 engine is wider due to the large 4 valve heads.

The 16V setup is the same as the 944 - the combination of the head & cam tower is almost the same size as the 4V head.

It's 31-1/2" at the timing covers which is the widest part. Valve covers measure about 28". The exhaust stays in that envelop and is the same on 16 & 32v.
FYI the shock towers are about 29-1/2 apart on a 928. Since the spark plugs are accesable from top you don't need any clearance uotside and below the valve covers so it could be a tight fit. Can't you use some struts with small springs to make some room?

Thanks for welcoming us 928 guys
The way I wound up with one is that in 1988 I had a 924 and couldn't help eyeing it for a v8 swap, I was thinking of a Buick 215 but felt that if I wanted a v8 I should just get a 928 so I did.

FRporscheman

Thanks Mike, and Hacker. That's really the point - it's easier and smarter to buy a 928 if what you want is a porsche v8 in a porsche. Sure you take on 500lbs but the car is built to properly control that power and torque right off the bat. I'm not a huge fan of 928s but I'll say this: when I would work on my dad's 928, I was always surprised at how thick and meaty all the suspension components were. Even things like frame rails and various mounting points for various linkages and arms are all heftier, and better designed. It's all because the car was designed as a Porsche from the beginning, the 944 is forever cursed to ride on a Audi-based suspension.

Do you think it will fit?

alex

Anyone who has seen the pics of your car wouldn't regard it as a "no class hot rod." You're at the top of the mountain I wish to climb.

[QUOTE=gina.kane;5096425]OK, had to speak up here.

Fact is it will not fit unless you spend mucho $'s building a custom frame. The 928 engine is a 90deg V8, unlike the LS1, so there is just no room.

The LS1 is also a 90 degree engine It just doesn't have double size heads.

The 928 block is also larger, it's technically a big block.

V2Rocket

i was under the impression bigblocks were engines of displacement over 6L..?

but yes pushrods certainly save a bit of room.

porschefig

No, there are 500+ cubic inch small blocks... There was a 396 c.i. big block and 400 c.i. small block... Displacement doesn't really have anything to do w/ it.

DVC

Thanks Alex. I hope you can build one too

hacker-pschorr

The term big block was never a technical description and has nothing to do with displacement. You can take a 502 block, and bore it to only 3 liters if you wanted to, would still be a big block.

All big blocks have one thing in common - bore spacing.
All small blocks are within one range, all big blocks are within another range.
The 928 engine has the same bore spacing as a 502 Chevy big block.

No matter what you do to an engine, the bore spacing never changes.
So the 944 is kind of a big block 4 cylinder

Example:
The 7 liter LS Corvette motor is a small block. Has the same bore spacing as the 5.7 (really 5.6) liter version.
