Engine/Tranny swap 986 into 914
I inherited another 914 recently and wondered about the feasibilty of transplanting a 3.2L Boxster S engine/tranny into this 1973. I currently drive a stock '98 Boxster as my daily driver and have a friend that drives a 2003 S which is way faster than my '98. I've also restored a 1970 1.7L 914 that is all stock. Has anyone attempted a Boxster S engine/tranny/ swap in an old 914 ? Not afraid of welding and manufacturing but don't really want to cut into the trunk or firewall if possible. Want to keep A/C because its too hot in Sacramento for 5 months of the year. Does anybody know the gross dimensions of what I'm looking for ?http://986forum.com/forums/uploads01...1405092240.jpg

Boxster engine is 36" wide & 22" long. Before bastardizing your 914 I would see what aircooled technology can do for you.

Too much work? Why not just install an Aircooled 3.2. Great motor no radiator and you can use the stock trans.
I would install a front oil cooler. You will like it! Van |
Why not an LSx or similar V8? It would certainly be a sleeper.

Or a Jake Raby built four.

Thanks I have considered all of the above suggestions at some point in the last six months since parking this car.
Here is my reply/concerns: Big engine swap or swap in general is always bastardizing your car. I'm not afraid to be a bastard... I have been most of my life. Not sure that an air-cooled engine is the best way to go especially in Sacramento where you would want to run your AC too. Sleepers are always the best, but V-8 conversions tend to be costly and most people (there are exceptions of course) don't do a very good job. There are plenty of good salvage Boxsters out there with intact motor drivetrains/cable shifters/radiators/EPU's, even 3.2L S's. Check out the Salvage Auctions. Even the early Boxster dash/instrument panel perfectly matches up to the old 914's. Just looking to the group to see if someone knows if someone has gone down that particular road before. Don't mind pain and work but would like to know if someone else has suffered first.... makes me feel better. |

In a perfect world I would need to only map/manufacture the motor and transmission mounts and modify the header/exhaust/ and mate the transaxles/hubs. Like I said before I would like to keep the firewall and trunk intact and hopefully keep the unibody intact. |
Having modern good working AC has little to do with the type of engine in the car. The AC system is a stand alone system that has to have matched components to work properly. The engine only drives the compressor. If you want to stay Porsche power I would go with a 3.0 or 3.2 911 air cooled motor. I built a GT clone with a 3.0 the car was fun :D. If you want to stray outside of Porsche power and want water cooled I'd go four cylinder Subaru there are plenty of conversions out there. Decent power good reliability and low center of gravity. And as stated earlier a Jake Raby built four might be the ultimate sleeper he builds great stuff.

Couple questions about your conversion: What mods did you do for the shift linkage ? The difference shifting my 914 and Boxster is well... like the difference between the moon and sun. That was one of the considerations. I know there are shift kits but a bit expensive. Did you add AC to your ride and how much did it cost? I see stand alone systems easily costing >$1500 in parts alone. Trying to be smart about the economics too... "financial planning" along with the design planning. |
Too hot in sacramento for 5 months? Did you grow up in Alaska? ;)
I've got a 3.3L flat six in the garage that needs a new home.. I would agree with the others, stick with air cooled, and why even a 6, too much weight in this car is no fun. Why turn a 914 into a boxster, with that heavy motor, you'll need P/S, P/B too, and A/C needs a radiator and so does the motor. Just get a boxster, I am told they are worthless without an engine for all who wanted to buy mine, the engine is the only thing of value, and so now you have to dig up a boxster motor, it will come with a car too for not much more. I mean you can do anything, just some things make no sense. http://i177.photobucket.com/albums/w...5/100_3682.jpg |
If you want to do it a 2.5 flat six would be great, could be technically difficult but that engine would suit the car great! A cool way to have something a little diffrent than what guys usually do.

Everybody has an opinion about what they think is best in their conversion. And everybody is an idiot if you don't do it 'their way', until someone does it right, now suddenly they are a genius. I'm neither. Just trying to gather information on what has been tried. All conversions are problematic projects. The intent of my post was to see if anyone in this forum has run into someone that has done it or at least tried it.If you know of someone locally, pass it on. The swap has been done in Austrailia, and Switzerland, and a totally ridiculous makeover (IMHO)by Wicked Garage, which really wasn't an engine swap at all. I would think that you would NOT need power brakes, power steering. Renegade has stuck an LS-5 and boxster 6 speed tranny without PS, PB. |
