Paul and Steve will do a great job. I've been working with Paul for almost two years and Steve just signed on also as one of our dealers. We've made quite a few of our Nickies cut for the cmw sealing ring which has shown itself quite resilient. I personally like the cmw ring because it biases towards the inside of the bore and rather than having a groove, it has a ledge, so you don't split up the sealing deck with a notch in the middle. It leaves more meat on the o.d. at the thinnest spot when you get to the really big bores. We've been doing cylinders custom for CMW for over two years now, and it looks like you have one of our latest revisions- all together you will have one hell of an engine (and car). Please post pics as it goes together :-) Good luck!

Looks like a great project and Steve is going to have lots of fun putting this engine together and getting it tuned. I'm nearby and may pop over to take a look at it before it gets buttoned up :)

This is going to be one of the best cars on the board. The anticipation must be killing you!
My own anticipation is very high, so I could empathize!

Will they tune the motor out of the car? On some sort of motor dyno?

Doug

911teo 02-28-2006 09:28 AM

They will do the initial tuning on the dyno...

Then I am going to drive my car up and we'll do a the swap. Steve is going to take my 3.6 out, install the 3.9 and do the in-car tuning.

I originally thought I'd have the motor shipped down.. But it just makes sense for him to install it on my car.

Steve is building a similar motor for himself (more aggressive cams and different ECU). I bet he'll have fun!

I wish I had more spare time, but I have to work to pay for all this stuff :D

Very nice project. The only thing that would get me slightly is the pre-galvanised tub. You better be on the lookout for the tinworm...

Little update...

The transmission (G50/31) is on its way from Germany and should be here at the end of next week...

In the meantime I just received the tail form Getty...

The build quality is impressive... Hopefully the fit will be as good...

The cutting has begun....

The flares from the old tub have been cut and will be welded on the 74 one (it has "steel" slantnose flares with brake cooling ducts.... Maybe I should have kept them and put a metallic mesh on it... oh well :( )

That was trans that I was going to buy until something more attractive came along, That is a 993RS trans, gearing will be just about perfect for for Teos mostly street engine/chassis: factory warranty, steel syncros, Porsche Motorsports 40/65 lsd, stiffer mounts, the second gear syncros alone were ~ $1500 a year ago.

The only thing better might be a /30 which is what I bought;),

I think Bill is the authority when it comes down to brakes and transmissions....

I'll try...

The G50/31 is the transmission that came with the 993 Carrera RS.
It is a 6-speed transmission with close ratios.

For me it was the perfect choice. Rebuilding my G50 with short ratios would have been expensive. Plus the "special" gears that you have avaliable in the market place are fabulous for racing but noisy for a street car.

The G50/31 instead was build by Porsche with the dual utilization in mind. The syncros are upgraded from the standard 993 transmission (G50/20 and G50/21) and the ratios are closer.

It also comes with an LSD (i think we'll be able to change the locking properties... we'll need to check that).

These are the ratios of the transmission

1st = 3.154
2nd = 2.00
3rd = 1.522
4th = 1.242
5rd = 1.024
6th = 0.821

R&P = 3.444

With my engine (assuming redline @7,500) and my rear tires (305/35-17) these are the top speeds in gear

1st = 52
2nd = 82
3rd = 108
4th = 132
5th = 160
6th = 200


And these will be the RPM drops

1-2 2,734
2-3 1,787
3-4 1,375
4-5 1,312
5-6 1,487

Should be pretty sweet... Bill did I miss anything?

911teo 03-16-2006 12:09 PM

Check this link for more infos about the 993 transmission ratios

And yes, Bill gave me the heads up on the transmission I ended up buying! He's always there when I need to spend a little more money ;)

The lsd is a Porsche Motorsports 40/65, non adjustable

Paul Guard has the edge in that and the strength deptartment.

i'll run the #s through my gear program for you

like I said that was going to be mine, I got the info courtesy of Bill H., who apparently likes to keep a very low profile but who is also building a very nice 993.

I am pretty sure they made it at the shop. These guys are very very good when it comes down to doing "special projects".

Another one of their expertise is building roll cages. There is a long thread on the racing forum about their approach.

I am going to have them build me a custom bolt-in roll bar.

Mahler9th 03-16-2006 01:32 PM

An interesting project. I have a '75 that weighs about 1950 and has a 3.8 single plug making about 360 bhp. Uses a 915. All likely a fraction of the cost of this project...

I drive it on the street, but it is not really in the "daily driver" category...

I can tell you that when I do drive it on the street, it is... somewhat fun!

there will always be a way to do something better and cheaper... that's the challenge that we all take upon us. Your carlooks fantastic and by the sound of it it's a phenomenal 911! ;)

Bill
thanks for running the transmission on your program! Awesome... After all I was not too far away in my1st hestimate!

Bigchill
The transverse tubing is nothing to do with the Smart Racing towers... It's a tool Zuffehaus will use to weld the towes in... I think!

Mahler9th 03-16-2006 05:08 PM

Well... make sure you have an ample budget for rear tires!

By the way, the builder of my car has basically the same thing (about 1950 pounds) with a 3.8 tt motor making about 700-750 bhp at 1 bar or so....

It too has a license plate and he drives it to and from work from time to time... I am sure that's fun!

jpahemi 03-16-2006 05:59 PM

Matteo:
I caught this thread late, looking at the jugs, the inner wall seems unusually thin; is this the max diameter you can go with the 993 case?
