i dunno dude, but my 4ac seems to pull all the way to around 6-7 grand with no problems.
Might just be the carbie...or your engine might be rooted, i dunno.
God luck with it though!
hey, my engine in the ae71 corolla i have is to say the least... really crap.
it really doesnt seem to rev well. after 4000rpm it starts slowing down and when it hits 4500rpm it acts like it hits a limiter or something. ( the revs just bounce down and it makes popping noises like what would be heard on a car with a limiter).
drft86 and i have been playing with the air/fuel mix in the carby a bit. Our guess was that its just been running really lean. The little glass thing on the side of the carby shows that there is less than half fuel running through, this was showing even after we cranked the air fuel mix up. and the car still ran the same (might have revd a little better but still did the same things).
I was talking to ken streeter yesterday as well, and he was saying to me he doesnt know much about the carby's on these corrola's.
Does that mean that the aus 4ac's in the corolla's and in the sprinters are different? if so how are they?
i know my car should be running better cause my mates old 4ac from the sprinter reved to like 7000rpm daily for a year and a half.
anyway, can anyone tell me what i need to be done to fix this engine? i do plan to put a 4age in sometime, but i untill then i do want to use this engine. and considering it would seem like most of my power is being made at 3500rpm... well im sure alot of you couldnt bear to be shifting that amount of revs when pushing your car
cheers

possibly check the fuel is getting to the carbie, might be a blocked fuel line, or maybe even a blocked carbie jet.
ok cheers mate. ill have a look into that.
i dont know too much about carby's so i wouldnt have a clue other than that.
does anyone know if the engine is actually different to the 4ac in the sprinters?
nope the corrola is the same engine as spoonter engine just fwd mounted so i cant see why there is different tuning involved
aslo the best way to see wats wrong is hook a vac gauge up to it and see what kinda reading ur getting and then go against the factory roller manual
its actually a rwd car and rwd mounted, not fwd (the front wheel one is 4a-Lc)
ok, thats good that they are not different tho.
head might be f***ed. I overheated the 4ac in my old ae82 & it still ran fine enough but with symptoms very similar to what you're experiencing
i think the 4ac's between the rollas & sprinter would be the same...they're both shit
bite the bullet and get a loan to buy the 4age package ken has for sale...diy you can have it in for under 2k
Your coil is f***ed. Replace that and see how it goes. Mine had the same symptons when the coil took a shit.
how much do they cost for a working one?
thats the bit that leads up to the distributor isnt it?
yeah i was gonna say that either your coil, plugs or leads are failing
