I know this subject has been beaten to death, but just trying to look for the most current information on parts as I know quality changes over time.
I am no longer doing a Subaru six conversion to my 914 as I will keep the T4. I have 2, one 2.0L and one 1.8L. My car is a factory ‘75 2.0L. I will run factory FI and am not interested in Megasquirt, carbs, or any other aftermarket FI, at least for now. The 2.0L I’m using I bought from George Hussey in 2009 “in running condition”, but it’s been sitting on my engine stand since. I am going to rebuild my 2.0L and bump it up to a 2056, but have some (a lot of) questions: Can I use the factory FI for a 2270? I don’t think so, IIRC, but want to make sure. I have the 1.8L that I could make a 1911, but is it any better than a 2056? Why or why not? What P&C’s should I use? I know the main ones are AA and KB. I’m looking at the Biral AA’s at the moment. Can I use a more aggressive cam with factory FI? What valve springs should I use and is there a better setup? My initial plan is as follows: - Install new P&C’s - Balance the crankshaft, rods, and pistons - Rebuild the heads: replace/upgrade the valve springs, replace the valve guides, inspect and replace/upgrade(?) valves - Either use factory cam or upgrade cam, if possible with factory FI. - Install a larger oil pump, if still available. While I want to make some improvements with the engine, I am not going to spend 10K+ doing so. This car will be a nice weather driver and I do not plan on doing any track events or autoX’s with it. I want to make the engine nice and “reliable”, but I don’t need new heads, Nickies, etc. I am rebuilding the engine myself but using a really good local machine shop as well. I do not need to get every Nth of power from the engine, but would like to reasonably improve on it without going crazy. Any advice on what to, and not to, do is welcome and I realize I’m going to get multiple different answers. As for the car itself, it’ll remain mostly stock with Factory 4-lug Fuchs, factory brakes, etc. Thanks! |

Are the basic AA heads worth a damn? The price isn’t bad, but seems a little low, IMO. They are sort of "the only game in town" and many use them. If I build a 2L I'll get a pair as well. If you look on AA you can find bare castings. The reason these are available is the fact that the serious folks use nothing but the casting... LN and Raby do EVERYTHING in house including the valve guide bores and seats. I believe they weld the plug holes up and re-position the plug as well. So, the new heads are "as good as are available" but can be improved on... |
