define "bolt up"?
any type 4 will bolt up, any 6 up to a 3.2 (I think) will bolt up with a 6 conversion.
The clutch and input spline can the problem with early Flat Sixes. Flat Sixes From '72 up, the input splining and diameter was changed for the 915 tranny. They also went from 215 mm clutch to the 225 mm.
Kennedy can make a flywheel to bolt up to most anything.
You will find finding engine tin, engine mounts and exhaust system to put a Type 4 in a bit difficult as it was only fitted to the 912E. There weren't a whole lot of them made.
maybe I misunderstood. I was thinking of 914 bolt ups, not the 911. I knew about the flywheel conversion, that's just part of the 914 conversion I wasn't thinking about the 911 with the vw engine.
big hp for little money is either the suby or SBC. not in the family. for the 911... I couldn't feel right about anything but a flat 6 in there.
for a 914, I've gone back and forth... if you want the most hp for your money, then chebbie. but with all that extra weight and hp, you open up other cans of worms.... 1st the Cvs can't handle it, then the 901 can't, then ??? so, imo, a scoobie is probably a lot more practical to get "enough" hp for your money, without going crazy. as much fun as a 914 with a 396 would be...
but even then, we are talking 225 hp? certainly under 300... and a lot of work for that. figure out your "budget", add 25% and see what you can get and what you have to do for each one... I think you'd be looking at a suby @ 225 with a lot of fabbing, a raby kit at about 185, and he did the hard work for you.. or a cheap, budget 6 conversion where you get absolutely lucky on finding some cheap parts for less hp. the difference with the 6 is upgradability later... something to think about.
I love aircooled, personally... I'd like to drive a suby conversion, but I wouldn't make one myself, I don't think.
