An S2000 motor would be even more awesome (IMG:style_emoticons/default/smile.gif)!! 240hp bone stock!! Kennedy makes the adapter plate. The only thing to make sure of is the rotation of the crank.

Or if you want super high HP and a custom install. Go this route... T.M.C. (Too Much Custom) (IMG:style_emoticons/default/barf.gif)




This is an advantage how? (IMG:style_emoticons/default/slap.gif)

The added weight in the rear helps with traction and pulling wheelies (IMG:style_emoticons/default/aktion035.gif) (IMG:style_emoticons/default/poke.gif)

Don't they have a peaky minimal low-RPM torque powerband as well?

As conversions go, a compact turbo like a Subie sounds good to me. Although I am not an engine swap kinda guy at this point. (IMG:style_emoticons/default/confused24.gif)

I just bought a 1972 with the intent of fitting it with a busa or similar cycle motor to it. If anyone has had similar thoughts or experiments I would love to hear about it.
I'm pretty certain I'll have to do it with jackshaft and sproket and connect right to the wheels through the bike tranny. If I try direct to the transmission I'm pretty should that would blow it in short order.

Any tips or suggestions would be appreciated.

I really like the audi 1.8T (Like Mike Bellis's) or the WRX turbo motor in these cars. I bet the larger 4 cylinder turbo makes a great combo...

I'm doing a x19 gsxr 1000 build in the "sandbox". That might help some as to how I am doing a similar install. Its a chain drive to a LSD utilizing a Stohr sports racer diff, carrier, bearings and gear. No reverse - but I could install a reverse using a "ring gear" and a starter motor. (See the Zcars website in england for further info.) Since the x19 is an old racer, it will only have forward gears as it will be a track day car. Be aware tho, starting and moving a 1900lbs street car with the very low mass clutch & flywheel of the 'busa or Gixxer isn't going to be optimal.

With that said, for the 914 you could use a simple steel subframe that spans from the rear and front mounts that would carry the engine and adjustable differential (chain adjustment). The Stohr diff worked for me as it uses the readily available VW CV joints. However, the diff aren't cheap nor easy to find. (I looked for a while for a formula SAE Diff in stock, before stumbling on a new Stohr diff on ebay.

Be aware that the 914 is heavier than an x19... and the x19 was designed for a water-cooled motor. You may be able to place a radiator with fans on a GT modified engine cover and get enough cooling, but that might be a stretch...

Have fun and just do it!

What makes my conversion work is the tune. Using a factory ECU tuned for a big turbo and methanol is awesome. It runs like a mild mannered Audi around town. If you put your foot into it, the motor comes alive and is a blast to drive. Once I get the drivetrain relocated in the chassis, the car will be mechanically perfect.

Nothing wrong with aftermarket ECU's. But I don't think they have the driveability or computing power of a factory ECU. The aftermarket can be tuned to give similar power results but still won't drive as well. I have no flt spots, no jerkyness, perfect idle, near perfect AF mixture, easy cold weather starting, and on and on. I think the Bosch Motronic 7.5 I'm running could be adapted to any engine if you have a good tuner.

Mike,

that would take a lot of money for tuning... I think that a honda ECU would be much better for that... Almost no money to get into the ECU and tune it and WAY WAY more tuners out there. But I agree a factory ECU makes things really really nice.
