77 Euro Carrera 3.0 case??

vanwyk4257 · vanwyk4257's Garage

I am purchasing a crankcase that is reputed to be from a 77 Euro Carrera 3.0.

The seller stated that the casting numbers on the case halves were:

930.101.103 5R and 930.101.103.6R

I believe these are the correct part numbers, can anyone verify this for me? Thanks!

Do you have the serial number or engine type off the top of thecase by the fan mount? That is the best way to tell.

No, but I can get it when I talk to him on the phone later. I just don't have any of my P-car books at work with me. Is the engine type number the one that's on the upright on the side of the fan housing support?

The serial number will be on the upright. The engine type will be on the flat that the upright meets. Both will be stamped in the case not raised like the casting number.

Thanks for the tip. I'll check it out tonight. I've already jotted down all of the possible engine type numbers for both turbo and NA early 3.0 cases.

Mike, the cases you are looking for should have engine type #

930/02 and 930/12 with serial no. 666XXXX or 667XXXX

The same case is used in the 76-77 turbo, engine type 930/52

This is What Wayne had to say about the case.

HOLY MOLY! Check out what I found at Pomona today!!!

Thanks Souk. It sounds like the one I've located is legit, I hope to confirm it tonight and then close the deal. I'll let you know if I find another one. :-)

You dog!

Glad you found one.

I just keep thinking about what a 2.8 RSR motor spinning at 8000 rpm would sound like. I'm sure I'll end up blowing my budget for building my car all to hell, but I don't plan on ever selling it so it's irrelevant. If for some reason I don't end up buying it I'll give you the contact information Souk!

I can't afford it this month

But send it anyhow if the deal changes...I can always sell Kevin to a certain Ranch in Nevada

for the funds.

I'm not sure I can afford it either, but I'm going to scrape up every penny I can since they're so darn hard to find. It's the one thing I can justify setting myself back for!

I still get excited when I read that description!

What did you do with that case Wayne?

you'll have a shorter stroke than a 2.8RSR!

With a 66mm nitrided crank, 2.2"s" rods and the right valvetrain I think 8000 is a realistic redline RPM. I don't expect to see 8000 often, I look at it more as something to aspire to!

I probably wouldn't take it anywhere over 7900!

Wayne,
How did you engine turn out? Weren't you building yours with a 70.4mm crank? Please hijack my (I mean your) thread!

jpnovak · 03-09-2005, 05:16 PM

Glad you found a good case.

I might be interested in the case. If you pass, PM me.

vanwyk4257 · vanwyk4257's Garage

Will do Jamie. I plan on buying it unless the price is at the high end of what's reasonable.

Nice score! These are not real easy to find.

type 930/02, 930/52 both have the smaller journals for the 66mm crank or a 6 bolt 70.4mm crank.

2.8 RSR was 70.4mmx92mm - dont spin to 8000RPM with a 6 bolt 70.4mm crank. Usually 11+:1 when using 2.7 or 2.4 heads. Plan on twin plugs and bleanding race gas. Huge torque, huge power to weight ratio, lots of fun, etc.

2.8 short stroke is 95mmx66mm - should be bulletproof to 8000RPM.

Either way it should be a hoot

Thanks. You're right, this one will be a 95mmx66mm 2.8. I'm planning on running custom JE pistons to get approx. 10.5 and then a set of 78-79 SC heads per Wayne's engine book. Fortunately there's a gas station a couple miles from my house that sells 104+ octane racing gas, so I won't have to blend it!

Woooohooo! S+ cams, right? You should be able to run a crazy cam with that compression and the short stroke.
