Hey everyone starting to get the pieces for my swap, currently have a WRX engine with complete harness. Picked it up for 1k complete with engine harness and body harness 80k on the motor. here are my questions:
Cooling: MR2 radiator with dual fans in the front? VW reservoir for self bleeding SIDE NOTE: I've been really interested in maybe doing something under the front bumper looks like porsche made a Mid mount radiator but my concern is its way to small (IMG:http://www.914world.com/bbs2/uploads_offsite/cdn4.pelicanparts.com-9388-1514740760.1.jpg) the other option is doing a deck lid mounted set up with 2 porsche mid mount radiators and using push pull flow fans, but can't find anyone that has succeeded with it? Cradle have a few options but leads me to my next question: TRANS: do i keep the stock and use the kenny adapters? about $800-900 or can pick up a forester trans with 160k for $175 plus axle splines, bell crank cables, shifter, pedal assembly with cylinders, 2wd conversion, GPS speedo, plus man hours i'll prob be close to $1500 to convert. my concerns with the subie trans are i would have to go to a floor mounted pedal set up and would have to figure out how to tie into the stock brake system. Think I've figured it out but seems like a lot of work and tweaking to get the bias correct. Resplined axles from dutchman should be easy, Cable bell crank is available online, 2wd is easy to get. thanks for all the help, this will be a long journey but will be worth it.

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. -Robert 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? |
