Any 2.0 owners out there who built a Short-Stroke 3.2L ?

[svonkampen]

Hi,

I asked Wayne what would be his pick for rebuilding my 1968L engine, and he suggested the "Short-Stroke 3.2L" engine mentioned in his book on 911 Engine Rebuilds......

I like my 901 tranny and he said it would bolt right on.........

Anyway, anyone out there with an early 911 featuring this configuration?

Ive got one, but its on a pallet right now. Ive never heard anyone say anyhting bad about the engine. Your car is smaller and lighter than most so it should be a real hoot to drive when done

Mine is setup with Webers. I have not confirmed a compression ratio, which pistons it was built with, or the cam. Im going to send it to Henry at Supertec to be refreshed.

Unless you build it on a early turbo casewith a 2.7 6 bolt crank you will probably need an adapter to hook it up to your 901. I think you can get the adpater from Patrick MotorSports. The 914 gang will know for sure.

Good luck!

I think Pelican sells everything you will need. Read Wayne's book a few times. Read Bruce Anderson's book a few times as well. They both document this engine.

Start with a rebuildable 3.0 core. Preferably a '78 or '79 SC motor since it has the bigger ports on the heads.

There are several different sets of 98mm P&Cs. Call (Andial) someone who really knows exactly which set of pistons and cylinders you need. RSR, and Max-Moritz P&Cs are not the same thing. They come in different compression ratios as well but try to keep everything under 10:1 unless you have budgetted for twin ignition.

What induction? CIS will probably be the easiest since it will come with the core motor. If you want to go to carbs, a decent set of Webers will cost you $1k. PMO's will cost you $3k. Budget $3k-5k and some more money for extra machine work on your heads if you want MFI. Just make sure you have all of the details hammered out before you start ordering P&Cs or any other parts.

Run a 20/21 or a 964 cam if you keep the CIS induction. Run something like a GE80 with carbs or MFI.

How is your oil cooling? If you dont have a good external cooler, budget for one.

Good luck!

Shuie,

Excuse my ignorance......

But with this engine my 1968 911L would do 0 to 60 in what?
I know weight is a big factor (my seats are Recaro Sport Seats) just approximately.....

Sell your engine and transmission and buy 3.2 Carrera drivetrain to slot in. It's much less fuss and cheaper too. 901 tranny is too weak and must go anyway.

[cstreit]

The early turbo case, or 76-77 3.0L carrera is the best place to start. I've got one in the shop. Very reliable and revs TO THE MOON.

I have a 3.2 bolted to a 914 (901) tranny....bolts right up... build the most engine you can afford to..

[Matt Smith]

Svon- do a search on my fellow countryman CamB's 69T-to-fire-breathing short stroke 3.2 build for some inspiration. He did it on a narrow body too, so all due respect.

He's been quiet lately (cos I think he's too scared to drive it )

A search will reveal all his worries and answers.

Thanx Matt,

Along with Pelican Parts we have everything you need. Try them 1st and let me know if PP doesn't have what you are looking for.
We have a great selection of used air cooled 911 based engine and transmission parts.

[350HP930]

Damn Henry. And I thought Dave White had a big stash of air cooled porsche stuff.

I think this debateable depending on the application. If you go easy on first and don't run too much torque the 901 works fine, IMHO.

[jgparker]

I second that. 901 is very robust, except for first gear. The shift patern is better too.

[beepbeep]

I just know that 901 has lower torque rating than 915 which itself twists it's case and wears down quickly when subjected to 930 torque.

Wevo Hayden can fill on this.
