Engine Swap

Postby Dreamstate » Tue Sep 23, 2014 5:07 pm

As most of you already know, I am not keeping this engine in the car for long. I don't like the idea of a surprise $10,000 repair bill when I'm driving to the grocery store. It makes me a bit nervous, so I want to get out of that as soon as possible. It won't be this year, but likely next summer I will put this engine up for sale and begin the swap.

I'm still weighing out the pros and cons, but I haven't decided yet on a gas or diesel engine. What I have decided on is that it will be a Subaru boxer engine. They are compact, reliable, cheaper than a Porsche to repair and have better fuel economy than the current engine.

Gasoline - EJ20
Pro - Cheapish, engines available all over the place, parts availability, sounds tough, plentiful aftermarket, easy power, anger Porsche purists
Con - Fuel economy (~20-25mpg), larger heat issues to iron out

Diesel - EE20
Pro - Fuel economy (~35-40mpg), reliability, more torque than stock, can get to 160hp with little effort, sounds almost air-coolish, explode the heads of Porsche purists
Con - Must order from overseas, overall higher initial cost, parts availability, possible transmission re-gearing ($$$), possible fuel pump issue, emissions issue??

Over all, either engine would adapt to suit the car's character. While the current 250hp is no slouch, it's not a super performer like the 911 Turbo, so I wouldn't feel bad about sticking a diesel into it.

I dunno. I'll be thinking about this all winter and doing more research, but may not decide until I get behind the wheel a bit longer and get a better feel for the car.

The Subaru swap is more popular than I first thought





Full build. I hope my skin is still thick enough from my Benz build.

I have a soft spot for those 3.3Ls... they can sound otherworldly

Carrera 4STi? Sounds good to me.

Don't be in such a hurry to condemn a person because they don't do what you do, or think as you think. There was a time when you didn't know what you know today...

Leaning towards the 2.5 STI motor this week.
Relatively cheap, an unstressed 300hp.

I support this... and I am stoked for more updates.

Also not sure if I mentioned this before, but the car is in WAY nicer shape than I thought. The damage is so minor and the rest of it looks so mint!
