Okay this has been a long time coming. I am finally going to pull my incredible, reliable, powerfully awesome 158 hp NA 2.5 Subaru Drivetrain. In goes my new 2.5 Subaru Turbo motor out of a 2009 Forester XT. I will be pushing 220 plus depending on if I upgrade my turbo over the stock one. Pretty sure I am sticking with stock to start. That is a pretty easy bolt on upgrade later. I have a 2004 WRX 5speed tranny to mate up to it. Will be doing a firewall engine mount connecting to a Small car motor mount. Tranny ears for the back. Using Outfront header to move the turbo around the front of the motor. Outfront Wiring harness to the Stinger ECU. Still need to figure out the intercooler but staying in the engine bay under a GT grill. More details to follow but plan to pull my old drivetrain this weekend.
Okay so plans have changed & I am going to be putting in this 2005 WRX motor with 55k on it. My 2.5 will go in eventually but my plans are to build it out a little more. Going to get a larger turbo for it & other odds & ends to push 400hp with it. So this 2.0 motor will be pushing 220 easy & looks great Attached image(s)

I'm not the guy to ask, since I've got a sum total of about 5 miles on my 914 so far. My donor car's engine came with a Fidanza lightweight flywheel and high-performance clutch, and it has no problem idling, no gear chatter (maybe my exhaust is too loud?!?!), or taking off from a dead stop in my teener. As Stephen mentioned above, our cars are light so you don't need the mass of a heavy flywheel to drive it smoothly.
I run an F1 Racing stage 1 clutch and lightened Cro-Mo flywheel in my M3-swapped BMW 318ti. It has a little gear clatter when idling, especially with the A/C on. But I'll live with that because it revs SOOOO freely... |
