I know there may not be a lot of people on here who will be interested in this for their car, but it will be nice to have more options for people who want more power, and a modern shifting mid-engine transaxle. These pictures are of a 6 speed version, but the 5 speed will use the same adapter plate and flywheel.

Is part of the plan to put Subaru engines in all those early Boxsters that had their motors go crispy? If so you got a PLAN dude! And I'm in line for one myself.

And I'm in line for one myself. This is EXACTLY the plan! I think VERY soon there will be a TON of these early Boxsters in the $3000-$4000 range with bad engines. I want to be ready when it happens... Test fit the engine today to see how it fits. It's almost like it was meant to be. It almost looks like the turbo might be able to fit in the stock location on the engine, although that's not what I will be doing on this car. There is almost 6 inches between the crank pulley and the engine bulkhead which is WAY more than the stock M96 engine. Next is motor mount fabrication.

The test car will weigh about 2300lbs with a full cage and track prepped. The classes I'm planning on running it in at first is NASA's TTS and ST1 so I will be limited to a power-to-weight ration of no less than 8.7:1.... so about 280ish to the wheels. |

Lately I've noticed that in forums where he used to spend a lot of time talking up T4 conversions, Shoptalkforums, Spyderclub, etc. the Subaru conversions have taken over. Not so many T4's any more, they're just too expensive. So Jake shifted to Boxster motors, which are a problem. Now you come along developing a way to put Subaru motors in Boxsters, too, again because the Porsche motors are so much more expensive. Subaru's are going in to everything, and seem to be following Jake around. No wonder he's so annoyed. |

The donor car I'm using was bought for $3500 (for a 2000 "S")because it had a bad engine that was mixing coolant and oil. I've seen 2.5 cars go as cheap as $2500 with bad engines |
