It's been a while since I looked into the necessities for the swap, but I don't remember the drive shaft being required. Is the length of the R180 housing different than the R160? Or is it a change in the pinion gear mounting flange that your drive shaft accommodates for? Either way, I may be interested.

No dyno time for the car post-swap. And it's actually still inoperative for the time being.

Funds got super tight over the course of the past year, but that has just recently started to change, so I'm starting to get hopeful again to be able to get the car running again soon.

The r180 companion flange is bigger than the r160. Length of shafts only change depending on 5mt or 6mt.

That is an awesome swap! I look forward to more pictures of this build.

is it time for a built motor yet?

we need to get some custom stuff!

My tech and I have a pretty good idea what all may have led to the destruction (8 trackdays in a month having a bit to do with it)...

Was it oil starvation?

Also, what made you go with an EZ radiator instead of an upgraded GD Impreza radiator?

That's our best guess. We'll be making a couple changes to try and mitigate this going forward w/ the second motor.

And I went with an EZ radiator because it has the dual coolant returns whereas an Impreza radiator has just the single. I didn't want to have to create a 'bridge' of sorts to make an EJ radiator work (like Patrick Olsen did).

I have an brand new 04 Roush Mustang Eaton MP90 Supercharger that's already reversed to spin the Subaru way if you want to step it up... lol

I have a 3.0r lego with an EZ36D swap, but I'm about to sell it to build an 02 Outback with an EZ30D and 5mt swap and an MR2 that's going to get a 2GR-FE swap so this supercharger has been waiting for a home but I keep passing it by.. Its prolly gonna go in the MR2.

Are you going to mod the oil pan with a baffle and maybe add some capacity with a deeper sump? I only auto-Xed my 3.0R but I had the pan off and could see how high gs could starve the pump, especially with that chain drive and all the oil needed for that.

Best of luck man.

Our approach is likely overcomplicated, but it consists of two parts:
1. Overfill a half quart to quart; run a bit heavier oil.
2. Per some research and theory, we're thinking the excessive track usage and regular exposure to high g's was 'storing' oil in the heads (yay boxer motor). We're plumbing the valve covers to twin (one per bank) external high temp oil pumps that will have lines run back to the sump. They're electric driven and the idea is to have a switch in the cabin to run them while on track, and have them force feed oil from the heads back to the sump for track days.

Thanks for the supercharger offer, but I'm actually pretty content with the 250'ish NA power on tap. I'm always a bigger fan of driving slow(er) cars fast.

How is this project coming along?
Reading your story has inspired me to take on the h6 swap aswell. I picked up an ez30r, and have begun rebuilding it.
Any advice when I get to the wiring?
Kinda new to automotive programming.

You can drill 4 new holes 45* off and then bolt the 5mt driveshaft to the R180. The centering bore is the same size.

any updates on this build?

Floppie · 01-29-2019, 03:01 PM

As somebody who's thinking about EZ36D swapping our EJ251 Baja in the future, I have a vested interest in this build. Super interested in updates

6 years later, how is this running for you? is it still going strong, any major issues, etc?
