No you have to change it out for a 914-6 or early 911 flywheel and PP.

They make an adapter ring gear that will bolt on to that flywheel and work with a side shift tranny, can't think of who sells them off the top of my head though.

early meaning 70-73?

Posted by: wndsnd Oct 11 2014, 08:25 PM

Earlier

Look for 901 102 026 01

I bought one recently and I think the cheapest I found was from partsgeek.com

You might find a used one somewhere..

Once you have the early (2.0) flywheel, you'll need to re-mark the TDC indicator on the flywheel as the bolt holes on a 2.4-2.7 crank are clocked differently.

You can use a 70/71 911 trans converted to side shifter with that flywheel. I have it in my car. But be warned, you have to use the 2.2 pressure plate, clutch disk and throwout bearing. And the throwout bearing is almost 300.00 new.


But you get to dispose of the clutch pulley in the process.

About 3 ways to go at this:
1/ that flywheel and an adapter ring with a VW bus 228 PP, pretty sure this is what KEP sells.

2/ early 901 flywheel and a stock 914 PP

3/ Clays method, BTW anyone looking for this I have a good TO bearing that I inspected and repacked for a third of that price.

The release fork design means the fork wears in the cup area, and I bought the last one Porsche had at least a decade ago. I just sold a bare "911" (2.2) trans case for a LOT of money. They go for big bucks because they have a tendency to crack on the top of the case above the diff. Personally, I wouldn't use that route again. BTW, a '72 911 clutch cable works perfectly with that conversion, and a good machinist can convert the 914 tranny to the 911 style release bearing ball. Still wouldn't do it again. 901 flywheel and clutch are a drop in the bucket compared to this.

I have a 2.2 trans in my '67 bug, wish I knew they were worth something.
I cut and welded the RB fork to make it longer and for the geometry of a bend I put in it. I'm using a stock 914 bearing and HD 914 PP, it works good.

Dont forget to flip the ring gear

Posted by: bigkensteele Oct 12 2014, 07:09 PM

The one I picked up recently is 901.102.205.0R

Posted by: Cfletch Oct 13 2014, 09:08 PM

why wouldnt I be able to use the flywheel and just buy the ring gear for it off of pelican? does it not work with the side shift?

Posted by: Mark Henry Oct 13 2014, 09:20 PM

The 911 ring gear is just a thin ring gear. alone it won't work

The adapter ring effectively changes your flywheel into a 914/4(or early 911, 914/6) flywheel, then most adapter set ups use the HD bus PP and 228mm disc.
The finished product fits like stock using the stock 914 TO bearing.

This is the set I made for my 3.0

oh sweet. just to be clear my flywheel plus that adapter will make it work? where can i find this adapter kit?

Posted by: Cfletch Oct 13 2014, 09:39 PM

also a dumb question. would it be possible to use the flywheel off my 1.7 or no?

Posted by: wndsnd Oct 13 2014, 11:47 PM

914 flywheels have a different bolt mounting pattern.

Posted by: wndsnd Oct 13 2014, 11:53 PM

914 = 5 bolt
Early 911 and 914-6 = 6 bolt which match the 2.0 - 2.7 crank.
3.0 and higher = 9 bolt

Posted by: Mark Henry Oct 14 2014, 06:01 AM

Although the set-up in my pics works well, my bet is it will cost more than sourcing a early 911-901 flywheel. On my engine it requires a 9 bolt flywheel so this adapter ring set-up is the only choice.
The set-up in my pics requires a different PP and disc.
The early flywheel just uses the stock 914/4 pressure plate (PP) and clutch disc which you probably already have.

The set-up in my pics I made, but KEP (Kennedy Engineered Products) sells one very similar. It's a "kit" you get the adapter ring, PP and the disc, plus a new throw out bearing if needed.
You may not see it on the site, but they have it, they're old school it's best to phone them direct.
