Protege5 Automatic torque converter durability?

[MuffinMan06]

I am turbocharging my automatic. I am buying a splitsecond afc to handle fueling.
I am upgrading the 3-4 clutch pack to add another friction and a heavy duty transmission cooler.

My only concern is the torque converter. Will it handle 160hp reliably with a heavy duty cooler?

it’s a 4f27e, meaning it can handle (27)0 ft/pounds of torque. that’s after the converter doubles it, so and i’ve looked into trying to get the 4f to hold power and i think it’s well worth the time to just manual swap it, just my .02 but it’s very easy to find a car with a manual to swap stuff to and from. i actually swapped my donor car with my old auto and it’s been driving perfectly since then. my friends girlfriend now owns it.

You’re probably right. I’m in over my head on this one

i think you should go for it but plan on a manual swap when it blows, or when you have a good opportunity. it’s fun with the auto the ecu seemed to adjust timing just not fuel. i’ve finally got my car running right this week after this whole year of trying to accomplish that and i honestly wish i did the manual swap with the msp ecu just to get it running and go from there. i also think its very possible to run the msp ecu with the auto one in parallel. i dont think you should give up on it but i think you should try and fail cause its not gonna cost you any more than it would either way

I am buying a splitsecond afc tomorrow so that should take care of fueling. I’ll run 5 psi to be on the safe side

you should be good then i think it should hold as far as transmission wise if you tune it right you should be just fine. i ran 10psi with no tune on the auto ecu and the engine was just fine in fact i took it apart to find nothing wrong with it but by the time i was in there i had an excuse to do forged internals. you’ll be fine, honestly it could be bad advice but if you throw a gt28 on there you could probably get by without an intercooler depending on the timing you run

I’m buying a full fmic setup for 300 and since I’m running the stock timing, it will help to keep the engine happy

i mean as far as boost goes the timing won’t be mapped on your ecu, it might just use the last timing value it has mapped before it goes towards positive pressure/higher maf readings than it’s meant for. it worked fine for my engine but if you want it to be reliable then i’m not sure what the best way to go about adjusting timing would be but i would imagine you’d want to figure something out
