Iam wondering which one of the 2 engine conversions are easier to do,.wouldn't the oil cooled conversion be the easy and quickest way to go,..??? I realize engine cost is a BIG factor, but seems oil cooled would be easier FM

A Porsche engine was an oem option, 914-6, and with a different motor mount, (pretty much) bolts right in.

The Porsche engine may be more money initially, but you'll be glad you chose it once you're done. It's a great project!

(IMG:style_emoticons/default/agree.gif) Haven't done a P6 conversion but I can't see how it wouldn't be easier than a Subaru engine conversion.

I'm getting started on Porsche 2.7L conversion. I'll detail the process (although this has already been done) as much to keep me on track as to help others. What I do know is involved are the following:
914/6 oil tank and fittings Early (65-69) 6 bolt flywheel 914/6 motor mount Front oil cooler and associated lines and fittings 914/6 exhaust headers (or very expensive heat exchangers) You will also need to make a decision on the fuel system. I am going to initially use the stock 1974 CIS injection system that came with the engine I bought. I may later switch to Megasquirt injection since I currently have that on my 2056 4. I believe I can keep the cost below $3,000 plus the cost of the engine so a total of about $8,000. I know that a Subi could be done for much less but I like the purity of keeping a Porsche engine. |

Depends on your skills, and what you want. since you said harder, I will go this way,but it all is a perception questions.
(IMG:style_emoticons/default/agree.gif) Porsche -6 it is all nuts and bolts with a little bit of cutting for the oil tank. Get the pieces, could be done in a weekend. That makes it pretty easy. Now for the proper question, so we could give you a better answer. I want to know what the best engine is for my street driven in the city car, that I take out for a long drive once a month down the To me your usage case and what you want the car to be in the end would determine the final out come. Shifting gears as smooth as butter, with a modern car feel, Subaru all the way. If we could get Ian to build kits again, or even use Renegade Kit, it is a bolt in affair also, with minor cutting for cooling. Renegade Kit uses the factory transaxle, so no smooth as butter shifting. |

If you live in an area where you do need heat, spend the money on the heat exchangers now that they are once again available. They work great (and hopefully fit correctly now), and keeps the car functional as defrost is also a nice feature to have working.
If you're using a 2.7, you'll need to change the flywheel to work with the 914's transmission as well. Enjoy the project in good health! |

A turbo on a 3.3 Subie is a whole 'nother level of complexity. The 3.3 came NA from the factory.

A turbo on a 3.3 Subie is a whole 'nother level of complexity. The 3.3 came NA from the factory. Not as bad as you think really. It is just a stretched 2.2Ls so all them piston, rods, etc work. Custom headers and down pipes and your done. (IMG:style_emoticons/default/lol-2.gif) Highly oversimplified |

What trips me up is the wiring on the 3.3,..and the fact I cant fab anything like a radiator shroud,or weld tranny brackets,..Etc,..So yes,...914forme,..I did mean as far as skill goes,..and tools aswell,..yea, a sheet metal can brake some tin for me,..its the electrical wiring,..I need help with, But ,..also the stinger ECU is 1800.00,..maybe small car would be less $$,.but a early 2.7 install would be nice also,..no ECU,no rad,just oil tank and flywheel,..I wonder how close the money is either way,.both engines are close in HP ,..but rebuild cost,..on a 2.7....well we know that story,..

I have a photo album that documents my 3.0L flat six conversion - pretty much what you see is what needs to be done!

I think a GT bodied 914 with a twin turbo Subaru boxer motor would be a hell of a car. If I had a deep deep pocket, that would be a fun car to have. I imagine a PMS build......
