Ive had a quick search around the forum but I haven't been able to find a definitive answer. Will a Diff from a BC (or BF) bolt into a BG5? Will the BG5 driveshafts fit etc? I am aware of having to match final drive ratio with the gearbox. Need to find a 4.444 diff to match a V4 STI gearbox and they are proving difficult to source down here in the South Island. Thanks in advance. Cheers

All sorted, looked to be a wiring issue with the turbo timer harness. I have removed the wiring and the starter works as normal. Thanks

Thanks for the replys, I have managed to take another look at the car. I unplugged the small gauge wire to the starter solenoid and it stopped cranking. That wire seems to be getting a constant 12V from somewhere. Also as soon as I did this the 10amp fuse at the top of the fuse box which I believe is for the dash cluster blew. Could this be related??

Long time no post... I am having issues with my Legacy. Basically every time I connect the battery the starter motor begins to crank and will not stop. This happens even when there are no keys in the ignition. The car is a BG5 Legacy with a V3 STI engine that I swapped around 4 years ago. The car has run fine with no issues ever since I completed the swap. I have checked and double checked all wiring and have now reached a dead end. Is there potential for a short in the starter motor? I am trying to get hold of a new/rebuilt one but I would rather not spend the money if I don't have to. Any other ideas? Thanks in advance.

Any fault codes?

*edit, Cleared codes but now it is majorly overfueling smoking out the garage!! firstly I would like to say this thread is an absolute godsend, thanks to everyone who has contributed!! Ive followed every instruction on here to the letter and finally fired up the engine. the only codes i have left over are 31 and 45. Is there anything I have done wrong to get these codes?? engine runs pretty rough and eventually dies. Im hoping it is something simple ive done wrong, but does anyone have any ideas? I have converted BG5A TT to a V3 sti motor.

is there anyway to keep the spotlights?

Welcome to the wonderful world of Subarus...

Would that even fit a legacy with abs?

Thanks alot. Still having issues with over boosting. I will check all hoses and post up again if nothing is amiss

Ho guys, I have just upgraded to VF26/27 combo on my BG5A wagon, what happens with the hose that used to go to the secondary wastegate as they seem to have done away with it on these turbos? Do I need to block it? or tee it into the primary wastegate hose 10 I think....? Thanks

Silver ones look fantastic on low BG!

Should be more like 10psi primary, 15psi secondary

New radiator cap should solve that problem. You probably weren't getting any pressure at all in your cooling system, making the boiling point of your coolant lower, which caused it to bubble over to the overflow. Does anyone know how to bleed the cooling system? (sorry for the hijack.) Or is it easy as running the car with the cap off....?

Faulty knock sensor perhaps? Same thing used to happen to me. would only run 7psi on both turbos, replaced the knock sensor and runs nicely now.

To the OP, hand in your licence. I was over 100 demerits a few years back (mostly passenger fines) and I was pulled over in a random check exactly halfway between Tauranga and Hamilton, believe me its no fun hitching back to town and finding someone to tow your car back over the Kaimais.

A box of beer will also help keep you sane.

check ecu... reset ecu???

My Wagon, excuse the date on the photo ha.

still having the problem, Ive not really had the time to work on it. I have recently changed AFM but I might switch back to the old one because it htink it has got worse. A bit of of info on testing coils would be mint too, surely they have some sort of resistance value they need to be close to or something. Cheer

Thanks alot, managed to get it, swear words were raining down all over, sure helped alot.

Hey any tips for reinstalling the intercooler on a BG5?? Apart from being patient? Im having a bit of trouble and dont really want to risk bending more fins. Thanks

Cars off the road for a bit now, so will have to look into it further.

Whats the symptoms of a fuel pump crapping out?? Ever since I bought my BG5 its been quite hesitant when you put your foot down from low revs, almost bunny hopping. And also at high boost the car is hesitant and on 2 occasions while passing on the open road it has completely cut ignition in 3rd gear at around 100km/h. I'm pretty sure its not the coils or plugs, as I have recently replaced the spark plugs, and the coils looked quite new, is there any way to test them?? Thanks in advance for any advice.

I had the same problem in my legacy, my bet would be airlock in the system as others have said, other than that it could only be thermostat which you have already replaced....
