Is this case worth saving?

I pick this engine case up with another engine I bought. Not sure if it’s salvageable or if it’s even worth saving. It had a rod come loose and beat up part of the internals. It’s a M96/70 case which I’m told it desirable. I usually stick to earlier stuf so it’s out of my wheelhouse. What do you guys think?

As beat up cases go, that one isn't all that beat up. Maybe have the internal webbing, where the rod bashed it, welded up.

Depends on whether it still holds water.

Yeah. I think that’s where the last two pics come in. I think that hole is where the water moves through the case. That said, I was told that this case can be used to build an air cooled engine. All I can find for a M96/70 is gt2 and turbo case. Does that make any sense?

I have a case that is worse than that where a rod tried to go through the same spot. Check for cracks on the other side. If It's not cracked, that case is VERY salvageable.

You won't get top dollar for it but it will run again.

Itís a 996 turbo case. Know nothing about building it aircooled.

Weld it up, pressure test it, and run it! Put Carrillo's in it instead of the stock rods; those are the weak link in the 996tt engines.

Dunno about making one air cooled. Never knew anyone who tried. Water cooling got you heads that flowed a LOT better.

Well. All I have are the case, a set of P&Cs, and three heads. I’m not sure I have the cash to build it. I’m probably just going to sell it all tomsomone who has the rest and needs a case. Anyone have an idea what to ask? I’m happy to make someone a deal. Not trying to make a ton on it. I figure on the low end of whatever the market is.

So. It has 964 casting numbers. Did they use 964 casting numbers on 996 turbo or gt2 cases? Is it possible that this is a 964 turbo case?

No, it's not a 964 turbo case because your oil return tubes are blocked.

What IS WEIRD is that it has the bosses for the air deflectors under the cylinders. This is extremely unusual on a water cooled case - they eliminated these.

So what you have is either a very early water cooled (prototype?) case using air cooled features before they changed the tooling.

Super cool find.

So. I wonder if it is actually possible to convert it to an air cooled case?

Yes, you need to drill out the oil return tubes and thread some holes (like the air deflector boss mounting holes) and a few other things.

Should be possible to convert.

Pretty sure that is just an early 996tt case. They all had the 964 part number until around '04 when it changed to a 996 number. Some '04 996 GT3's have the 964 case also. In your first picture showing the case part number, it looks like the year date code is visible... its the round stamp to the right of the case part number.

It was interesting to look under my '88 Carrera and '05 GT3 side by side, while not identical the case looks exactly the same. My '05 has a 996 part number case.

M96/70641 is a 2001 996 Turbo, 414hp engine. Nothing that unusual about it.

Ok. It sounds like it’s settled that it’s an early 996 turbo case. IS it worth anything?

It absolutely is! Structurally, it's probably ok. Some light welding and grinding IMO is all that is needed.
