Original 6 - Rebuild or upgrade Options

[kenschipper]

May need to rebuild the original 2.0 6 in my 914-6. Trying to decide whether I should do the rebuild or replace the motor with a 3.0 or 3.2.

I love the sound of the original 6 but would appreciate a little more low end torque. I'm not sure that rebuilding the original 6 would be any cheaper that the 3.0/2.3 swap. There is a 3.0 with fresh rebuild on ebay right now that will go for less than $9,000. Those with experience may want to chime in.

Another question is whether to go with fuel injection or back to Weber's or PMO's. I know of all of the advantages of injection (more reliable, less power loss in the mountains, probably better milage) but the sound of carbs is hard to beat.

Do the 3.0/2.3 engines require an external oil cooler, don't remember at the moment.

Does anyone remember a link here on the site dealing with a 3.0/3.2 transplant.

I've got a 3.0 in my '74 conversion. I once had it in an orignal six, but sold the body (getting weak). If you got a 3.0/3.2 I would add an oil cooler either up front or under rear trunk with a thermostat. Others who have them in the rear can tell you how they work. Mine is up front. Out today for a drive in mid 90's weather and oil never got above 190-200.
I'm using a kit from PMS for the 3.0 clutch. Went with the "puck" disc. Gives me no problem street driving. The kit lets you use the stock 901 box with the 3.0 flywheel/ring gear.
I've got Webers. What I had already. A friend has a 3.6 with FI and it's sure nice to start it up and GO.
You might consider upgrading brakes too with the larger engine?
That's the only issues I can think of, oil cooling and engine to tranny. If I've missed anything others will chime in.

What size webers did you go with?
