Information on G50 conversion: parts list needed
 

I am stripping down my '89 911 and want to put together all the parts required for a G50 conversion package.

Right now my list is composed of:
G50 transmission with mount
clutch slave cylinder
shift console and shift rod with coupler
used clutch, flywheel, pp
longer case studs
pedal cluster with clutch m/c
brake/clutch fluid reservoir
transmission speedo sensor
starter

Is there anything else I am missing?
The car/transmission has ~84000 KM (52,000miles), any idea on a value for this?

Thanks,
Todd

Just keep in mind the shfter assembly isn't a must to include. If the buyer has a racecar, they could easily use a Fabcar or Hargett shifter which would be more to their liking in terms of positioning the shifter. But for a street car the stock shifter & main shifter tube (with trans shift coupler) is a straight bolt-in affair.

The clutch doesn't always need to be included because the G50 conversion, if converted to a short bellhousing, needs a custom clutch anyway. But if it's going in a car doing a torsion bar housing adjustment/replacement, then the stock clutch can indeed work.

I think it would be helpful to include the clutch hydraulic line piping. The flex line section at the rear would be easy to include. The hard lines from the pedal cluster to the front of the trans are a bit harder to provide.

You should include the clutch release fork assembly, which suspect you would as part of the clutch or trans itself. I just didn't see it mentioned in your list

You really don't have to include the brake reservoir if you wanted to keep it with the brake booster & master. Someone could easily mount a separate small reservoir if they wanted to for minimal cost . The factory reservoir is indeed nice to have though, since it combines the fluid for brakes & clutch in one container.

I don't think you don't need to include the starter. 87-89 Starter is no different than earlier starters (72-89 I believe are all the same)

Nice of you to include the speedo sender!

May want to consider including the drive axles? The G50 has 108mm axle flanges and the earlier pre-1985.5 axles won't bolt up to the trans w/out them.

Is the trans an LSD? That seems to add a lot of value to an already valuable trans. Trans alone with LSD is ~$4K. Other parts make the complete package around $5K-$6K depending on whether it has a LSD. However, keep in mind some would say the factory LSD for the G50 is not all that great.

I can send you a couple estimates we got from PMS to do a short bellhousing conversion on a 1970 racecar. Cost is way up there but the actual parts list might give you some further information on parts used in the conversions. Obviously for a racecar, a lot of the fancy stuff you can do without.

Kevin,
Thanks for the detailed info. The trans would include the clutch fork assembly. I will look into the difficulty in removing the hard line from the pedal box to the flex line on the slave cylinder. I'll take the starter off of the list and add the axles as well.

The trans is an open dif so a little less value in the parts there. I guess the next step is to assemble all the parts and throw them up in the classifieds and see what interest there is.

Thanks again,
Todd

For comparison sake, we were pricing out what the aforementioned short bell G50 would be worth to sell separate from the 1970 race car, since for whatever reason it just isnt' selling as a complete car. We figured the short bell G50 would be about $11K. But that one has the shortened housing & mainshaft, short gears and a Guard LSD. Nonetheless, the rest of the parts we discussed would go with it. Our package cost consisted of:

pedals, fluid lines & reservoir
shifter assembly (Hargett unit)
clutch package
axles
custom PMS adjustable trans mount
Guard 3,4,5 close ratio gears (stock 1st & 2nd)
Guard GT 50/80 diff


Glad to help. Good luck with the sale.

Am I missing something here, isn't an '89 911 already a G50 car?

Hey Steve,

Todd is stripping the '89 and wants to sell-off the G50 as a complete-as-possible conversion kit
