bonkas tired old Lancer EX - Engine Swap/Build Thread


Recommended Posts

My issue is I am retrofitting a newer 90s alternator and only using the sense and bulb wires, auto electrician said voltage would be high as it is not computer controlled. 

Not sure there is any way around this without putting old anemic one back in... 

When I tested the sense wire it had exact same voltage as at battery, will need to check again.

Auto electrician is not making sense. Computer controlled alternator my ass.

How exactly is it wired?

I have an RVR alternator on my LB. Used the 2 wires that went from the alternator to the loom(instead of the external reg) Works well so far, pumps out 14.7v to battery in boot 

Exactly this ^

I am only using the S and L Pins and getting about 15.2v.

The alternator was tested and put out ~14.5v which I was happy with but 15 just seems too high.

I have had to charge this battery a few times, maybe this is the issue... Maybe if I give it time the voltage will drop as battery charges.. The battery was only at around 12.2 resting voltage when the car was started.

Carbs sound cool

 

@1.54 in your video sounds like it is pinging though, might be too much timing?

Haha, yeah! The noise went away when we took out the loose catch can we realised was left rattling around in the engine bay :D

Dunno 'bout drag day @Roman but will definitely be at 2020 nats!

The bucking misfiring feeling when cruising has put me off driving it too far. This was not an issue before they dicked with my distributor so I suspect it's timing related.

It does seem quick but the slow gearbox and my slow brain make for some very slow gear changes and the gears run out fast haha.

Also @Roman the voltage seems to have settled down to about 13.9-14.4v now, not sure what was going on, flat battery doing wierd stuff?

Post fuel economy dataz when you return plz 

So far a lot more impressed with this setup than I would have imagined.

Suits the car so well too. This whole thing is just great.

I'm sure you'll have worked out all of the niggles soon enough.
