The MT5 cases changed some say the latter ones are stronger than the earlier ones. My feeling is they are cheaper than a 901, and stronger. Your making them 2 wheel drive, so less stress on the trans.


I had that thought too, but then I realized that on a stock 2.5 NA (say 160 HP) the center diff sends 55% of power to the rear wheels and 45% to the fronts, so ~ 75 hp to the front diff.

When we lock the tranny into FWD we are sending 100% of power to the front diff, so in my case (EZ30), close to triple the power the transmission was designed for. That said, no problems so far (10k miles + of fairly abusive driving)... so it can't be that bad!

Actually that's a VW VR6 corrado? radiator. It also does great in stop and go for a rotary which runs hotter than normal piston motors (I bet it can handle a non turbo subie 4 cylinder). The car does run a bit hot on hot days,, but I think this can be resolved with better ducting from underneath as there is none right now. As far as engine access,, I have no problems changing my spark plugs,, and changing belts is still easier than on a type IV.

How hot is a bit hot? I still hit ~210 in my EZ30 with a front mount rad on 95deg + days here in Denver. I too am sorely tempted by an engine-bay mounted radiator. Less/no cutting, much shorter coolant lines, no ground clearance issues, less weight (less coolant to fill the lines). There is a lot to like if it works!

How many miles have you put on it?

Picked up a 5mt. found a very knowledge fabricator and is going to help make cradles using my car as a mock up. Ill keep everyone posted. Looks like it will be a coldwater/ renegade style front and were going to figure out something for the trans. We're also looking into a cable shift step up. Hopefully will have something done in the next few weeks.

This is exciting news!

In my opinion, A well designed cradle would re-use the soft rubber mounts that the Subaru uses for the engine and transmission, and then would hard-mount to the pickups on the body.

In the current coldwater setup, he engine soft-mounts to the cradle, but the transmission mounts hard-mount to the cradle, which im sure sets up some bad vibration/fatigue issues.

Also, using an engine mount that only picks up at the front stock mount points will have a hug cantilevered mass which will be a lot of stress on those forward mounts. I'm almost certain that the engine mount needs to to support the entire engine/transmission assembly as a single unit.

thats what i was thinking. Going to see about getting him to do something similar to DBcoppers set up, using the subaru stock trans brace. the only issue i can see for my situation is using subaru rubber on the frame is space. Im running a wrx motor and with the stock down pipe its tight.

Hahah once you have a turbo car you never want to go back! Twin turbos 6's have been my favorite so far.

I don't know... I have a 2.0 WRX and definitely still prefer the EZ 914. I need to find someone with a turbocharged conversion so I can directly compare the two!

Perfect! (provided I can make it) pretty busy summer coming up! Worst case RRC?
