www.911pcar.com Who's dealt with them before? I'm looking for a transaxle for my V8 914 and am considering a 930 or G50/52 (yah I know - it doesn't fit easily but I would really prefer a trans with decent shifting). They seem to have prices that are a little too good to believe. They don't list current inventory, but supposedly what they've sold in the past. $3500 for a G50/52 with 14K miles, $2000 for a 930 with 34K miles.

Actually, their website is very confusing and I just noticed that all of the items with prices are listed under "SOLD". Of course, a bunch of the lisitings under "SOLD" ask you to call for the price, which makes no sense.

BTW, what's the deal with using a G50 in a mid engine car. Do they have to be run upside down, like in an Ultima? Or can the R&P be moved to the other side? I suppose I could go with a dry sump system to get the engine lower (which would make more room for the fuel injection on the top) but would rather not.

Did you consider a WEVO 915 box? Or is your V8 too big for that?
I think it would cost close to the same, but it's a lot cleaner install

The G50 will need to be installed upside down (can't flip the R&P)
You need to take care of the lubrication of the tranny (because it's upside down)
And you'll have to fab a shifter mechanism or go for a cable shifter setup www.brandwoodcars.com

I'm sure other will chime in on this thread...

cheers,

Regarding L.A.Dismantlers; The web site makes them look larger than they are. It's really just a small yard. I drove by it twice before I found it. Both times I needed a part I couldn't get anyone to call me back so I drove over there. Probably my little part needs don't get much attention. You might have better luck buying a gear box.

I have bought from them. You have to deal with them in person and want a engine or tranny. They really dont sell trinket Porsche stuff and they only have one Porsche guy that know's his stuff and he runs another business next door so they have to track him down each time you need something.

The 930 box wont shift any better. It will handle ANY engine you put in front if it.. but only the G50 shifts better (Borg-Warner style sliders/synchro's) Yout cant flip the ring gear in a G50 and nobody makes a new R+P so you can flip it. It runs about 5500$ to flip a 930 box after purchasing one (800-1000$) and then all the machine work and replacing all the worn parts..then shift linkage/HYD clutch...axles/CV's...5500$

The 915 flips with little/no machine work.

Well, I think the 915 is out. The ratios are poor for a V8 and it's torque capacity is still wanting. I think I'd rather put the money in a dry sump system than all the machine work for the 930.

So if I wanted to buy a G50/52 (or maybe a G50/50 would be better since I think its a little shorter) how would I know if the used one I got was OK? I don't want to buy one and then have to get it rebuilt (no doubt for several $1000's).

Isn't the pre-1987 Turbo gearbox a 915 4-speed? I would think perfect for you in terms of mounting, torque capacity and gearing.

Negative. All Turbo's up until the C2 Turbo in 91/2 had a 930 4 speed box in them. A lot of people with turbo's yanked the 4 speed and replaced it with a 915 5 speed however.

Ridder,

I would try and use a 88 G50 from a Carrera (which I had for sale for 8-10 months. for 1500$) Most of the G50's are still in good shape. You shouldnt have a problem locating one.

Also.. on the Ultima note. We have a local builder of the Ultima. He is in Morgan Hill. English fellow.

Oh.. BTW. The G50 ratios are not correct either. The Ultima gets away with the box because they run 17inch+ wheels with a fairly tall tire.

Hey B,

Speaking of the Ultima shop in Morgan Hill (which I've been to, to drool over the Ultima in person), think our other "buddy" has joined this site?? (IMG:style_emoticons/default/smile.gif)

>BTW. The G50 ratios are not correct either

Ratios according to various web sites (with final drive):
930
1 - 9.50
2 - 5.49
3 - 3.76
4 - 2.74

G50/50 and G50/52
1 - 10.86
2 - 6.16
3 - 4.37
4 - 3.33
5 - 2.60

The '89 turbo had a 5 speed box (G50/50 IIRC). This was the last "impact bumper" model of the turbo.
Before that they all had the 930 4 speed

A stock G50 (from '87 through '89 on the 3.2 carrera's) has a real f-in short first gear (even for a stock 3.2)

cheers,

Jeroen

The only gearbox I would ever want to use in another V8 conversion, is a ZF.

I think it's a much better choice than dumping $12k in a fantasy box. I had a 72 Pantera for about a month, it'd fit fine, and take 1000hp "Mikeys".

Oh yeah, it's only ever going to cost you around $2k for a full rebuild too. (diy)

Yep.

And you get to do away with those pesky CV joints in favor of U-joints!! (IMG:style_emoticons/default/laugh.gif)

Are ZF boxes easy to come by?

I dunno how easy, I have seen several every year, and afaik, they are available somewhere NOS.

I have seen maybe 3-4 (casually looking) in the last year, from maybe $1000-$1800.. I dunno bout condition.

That ZF box would be hanging out the back of the car..

Thanks for the info Jeroen on the 1989. I didnt recall the last CIS Turbo to have a G50-50.

FYI: the current racing transmissions for Porsche are based on the G50-50 box (Carrera Cup/GT3RS)

A V8 914 with a 22inch tall rear tire will do 45 mph in first gear at 6k RPM with the 930 speed.

"_________________________________36 mph ________________________ G50 5 speed"

I have driven a lot of cars with the 930 box. The ratios are just right with the torque of any decent built SBC
