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! |

First thing is to disassemble what you have and make decisions from there.
Heads cracked? (common on 2.0). You will need expensive repairs or new heads. If you're planning on re-using the D-jet cams are critical. You can't go big here. I never "make a list" until the original engine is in individual pieces and I know what is re-usable. The Biral cylinders caught my eye as well. Porsche tried it once and even they found it difficult to adhere the aluminum to the ferrous liner. Don't expect the Chinese to do a better job! Unless it says "made in Germany" it's made in China. I don't use Chinese parts if I can avoid them. Most of the OG members don't use Biral. In fact. there is enough troubles and complaints with the aftermarket parts (everything including the bearings) that I am planning on using the original Mahle cylinder and having them bored out to 96mm which is actually more expensive that just buying new. Re-boring the old allows you to choose your P-C clearances as well. You need a GOOD machine shop for this. You should tear your stuff down, inspect it properly, and do a BUNCH of research before you start buying parts... |
