Will a 928 engine fit into a 968?

That is one serious machine. If and when I get to have my own garage, I want to do that!
I once saw a bmw M5 engine shoehorned into a mid 90s 3 series, and the way they got it to fit in the engine bay was by tilting the engine over by like 10 degrees... Would this help get the 928 engine into a 944/968?

But the 944 engine is an inline configuration, tipping it over makes it take more width. It was probably tipped over due to it's height, or else it allowed smoother operation or something. V8s are wide, and rolling them over a bit makes them take less width. With the M5 V8, tipping it over allowed one of the cam towers to clear one of the shock towers. At least, that's how I figured it... Maybe I got it wrong.

This is one of the sickest cars I have ever seen. LS1 makes over 300 rwhp stock and getting 400 isn't that hard. It is so much cheaper to get power out of the LS1 compared to the 928 engines, plus the pushrod motors are so much smaller and lighter than OHC motors.
#22
WOW!! That is one clean swap, and the LS1 is high tech, reliable power. I'm pretty sure getting this sort of final result requires time, patience, knowledge, and mucho dough. Hard to believe how much clearance between the engine and suspension towers, stock 951/968 engines are tight fits alright, now that's VERY impressive!

did you just say the ls1 is high tech??? pushrod is not high tech , quad cam with vario cam is high tech...the only reason they keep getting more power out of the pushrods is they keep upping the capacity, that is not hard to do.

Is that a plastic intake manifold? If I put an LS1 into a porsche (which I wouldn't mind doing), I would definitely customize some stuff to make it look less like an american engine.

yes, the LS series uses plastic composite intake manifolds, I believe they are nylon based. It is a good idea, it is lightweight, strong, and insulates rather than conducts heat. The LS1 is every bit as sophisticated, probably more than the production 4 and 8 cylinder engines that porsche could pull off back in the day. The 968 engine and the LS1 are about equal in technology. Technology has progressed, it cant be avoided.

tell me in which way is a push rod technology as sophisticated as twin cam with vario cam? are you serious. see that plastic manifold GM only do that because it saves them a few cents and guess what THEY CRACK AND DISTORT. now thats technology for you. they persist in giving the public extremely old technology and they get away with it, stupid is the person who buys one of these. the only way these engines make power is to add cubic capacity, it cant get any more basic technology than that. they use the same LS1 engines here in australia in the holden commadore(i mean commondoor) and monaro. and they have all this advertising saying how it makes 300kw at the flywheel. it probably would if it could rev to 10 000rpm, but it doesnt. we have dynoed a few of these and all we get is about 240-260 hp at the wheels. it must have a lot of drive train loss. technology my ****.

Yeah, I heard those composite intake manifolds crack with heat. Wtf... And I have to agree that there isn't much about an LS1 that's high tech except the chemistry of the materials used. The OHV versus DOHC point, for example. What makes you say the LS1 is high-tech?
#29
What makes you say its not ?
4 valves per cylinder is not a high tech Revelation its been around since the 1920's
If an engine has good numbers so makes good torque and power with long service and low weight resonable fuel consumption various loads it's a good engine that simple ...
its pretty near sighted to down rate an engine if it has push rods or an Iron block ..
can anyone tell me when they stopped using iron blocks in F1??

Old thread!
My opinions have changed a lot since then. I dislike the porsche alusil engines and would love to have an ls1. 4v may be from the '20s but it wasn't mainstream until much much later. So what's high-tech about the ls1, now that you brought it up? I'm only curious.
I now believe in simplicity and robustness, so I'd love to have no BS (balance shafts), timing belt, aluminum cylinders, leaks up the wazoo, and blown head gaskets! So keep the 928 engine away from me!
