3.3L turbo Pistons & Cylinders

[mbrown]

Hey Guys... I am currently rebuilding a 911 SC 3.0L engine (turbocharging it) and I'm looking for turbo pistons & cylinders. I have seen some on ebay with the following comment: "note the shorter cylinder height, these can only be used in turbo applications" What does this mean in terms of fitting onto my 3.0L engine? Are the 3.3L turbo pistons & cylinders a direct fit (or do I have to offset the rod bushing etc.)? Regards Mike

The 3.0 turbo p&c's should work from 76-77. They are extremely low compression due to no IC and CIS. The P&C's from a 3.3 will only work if your splitting the case during build up. The pin size and height are off for your crank.

Yes you can MAKE them work. Options I can think of off my head are:
1. Have offset bushings machined in your current rods (Supertec)
2. Custom Rods
3. 3.2 internals swapped in and get a 3.3

Budget, and desires are determining factor. They are NOT a "bolt on" to your short block as is.

Mike:

Do you have Mahle or KS cylinders on your 3.0?

Yes you can if you machine the rod bushing and have it offset yes Supertec can do this for you.

This is my 79 SC engine using the 3.3 pistons and cylinder setup using the Supertec rod bushing modification. I am using a 86 3.3 turbo intake with a Euro fuel distributor and the Supertec twinplug distributor conversion. K27 turbo and a 1080 CFM intercooler.

I wasn't out to build a monster engine or the fastest car, just looking to get a little extra horsepower to push my 2200 lb. 914 down the road a little quicker.

COOL!! Share some pics. I want to see that steed.

Cars in the body shop getting a new black paint job and the interior is at the upholsterers getting fitted in leather. So the engine still sits waiting for
the rest of it's body to come together. Give me a month or so to get it together then I will post some pictures with dyno results.

Gentlemen...

Thank you very much for your comments.

Lukesportsman: I have the 10-fin KS cylinders. Guess that means I'm in the market for Nikasil cylinders?

mb911: How about those 3.3L p&c? How do I contact you to negotiate a sale?

Any idea what it costs to get the rods offset machined?

Mike

I think Supertec charged me around $300.00 for the job.
