Planning a rebuild on 914-6 2.OL motor (1969 911T)
Any thoughts on the most bang for the buck (bang more important than buck) on a 1970 1914-6 motor. I would like to upgrade to 911S specs. Please help me with your thoughts and a proposed parts list.

T to S
this is just an opinion, but I think if you have and original motor 914-6 then I would find an S motor and rebuild it for the car and store the original. A lot of little differences between the two motors make a big difference in reliability and $ spent. the individual strength of materials between the two are significant, forged vs. cast.
From this I will yield to the more informed and experienced. Best of luck, rusty |

search for tag 901/05 for all I know about doing a 2,0 rebuild.

Well you have the universe open to you...
are you trying to be period-correct? how fast? transmission life? in reality there is no cheap option, they are equally expensive. The best bang for the buck is a carbureted 3.0L with 911S-Spec. compression and some decent cams.

Tell me about it. You can literally spend about as much as you want on a 2 liter motor - and the parts and labor costs are identical whether it be a 2 liter or a 4 liter. If originality and/or small displacement are as important to you as they were to me, stick with the 2.0.
If you want 'S' specs, there are far better cases to begin with than the flimsy 1R case that came with the 914-6. Plus, if you hole that case, you will be crying. I would have shot myself a year ago for saying this, but if all you want is a nice motor, build a...gulp...3 liter. If that is a deplorable option to you, I'd find an early aluminum case to build a motor on that. I went the small spigot 7R route and $2200 of machine work later, I'd suggest the aluminum case is the MUCH cheaper route. If you are insistent on staying cheap and using what you have, I'd absolutely recommend a 2 liter motor with a set of nice used 'S' pistons (or even Normale) and some of John Doughertys "Mod-Solex" cams. I'd swear that even without opening the ports, my little '65 in this config is just as damned fast as my 2 liter 'S'. I have never driven a more fun small bore motor in my life.
