So a while back my car started over heating, It wouldn't heat up immediately, it took 15-20 minutes of driving before the needle started to climb. It's a turbo'd b18c block, sleeved and built in a 1994 civic del sol si.

I bled the coolant system. no change.
I replaced the thermostat, no change.
I took the thermostat out, no change.
I bought a bigger radiator than the stock one, no change.
I flushed the coolant system, water flows freely through it, replaced the coolant, no change.
I checked the timing, it was fine.
I replaced the head gasket, still overheats.
Doesn't look like it's running lean.
It isn't loosing any coolant.

I've run out of ideas here, if you've got any please contribute.

does the fan kick on? did you bleed the coolant system with the heat on all the way? do you have a new water pump in?

The fan turns on, the coolant system was bled with he heat all the way on.

What good will a new water pump do? i was of the impression when a water pump wears out it doesnt stop pumping it just starts leaking. There is no coolant leakage.

i was under the same impresion as well but aftergoing all the stuff you have went through i had finally changed mine (it wasnt leaking) and it did the trick..just a suggestion but rarely the prob but in my case it worked for sum reason or another but wen i pulled it there was all crap/dirt in and around it...idk if that was the prob or not.

Doesn't happen often with hondas, but if a bearing or something fails with a water pump that would definitely cause overheating. Had it happen with a DSM I used to have. How many miles on the water pump?

what kinda fan are you running? if you got a slim fan that could be the problem as well, just a thought because wen my friend got his car tuned at T1 his car started overheating due to the slim fan, they told him that the oem fan was best for cooling. i know that the car is gonna heat up more since you're revving so high so many times but just a thought if you do have the slim fan

the radiator cap was replaced with the radiator. it is running a slim fan but i know other people running the same setup without problems.
