Are you running an intercooler? I forget how you got it set up.

not yet... but ive installed the right O2 sensor this afternoon (heated one).. went for a ride .. tuning is very good up to 4500@wot / 15psi @ 6degree timing without intercooler (in a throu tbi setup) (no fuel left after that !! lol )... but rad stick this temps even on idle (from cool to hot) :S ... im replacing the rad cap tommorow morning hoping to get rid of this new problem ... also trying to find a way to increase the fuel pressure so i can juice it plenty towards the 6000rpm like im used to... pretty good for the TBI i guess ...

wath else could be wrong im not hearing detonation at all :S

Wonder if you have the infamous voltage regulator problem? Does the fan switch on and stay on?
Glad to hear your Coup is running strong.

my car was taking a decent amount of time to warm up ( too long in winter for me ) and the temp would fluctuate so i changed the thermostat ( the nissan gasket was worthless... high temp silicone all the way

oh and the old thermostat was stuck open quite a bit i later found out ) and now i dont have the annoying bouncing temperature guage.. now it just runs hot when im stopped, till the fan kicks in so im debating on wiring up another fan onto a toggle to get it to cool faster.. Crazy, if its an air bubble, shouldn't it work its way out? I had to squeeze the upper rad hose to get most of the air out of mine but all of it came out in the end

actually i did convert that thing over since i wanted a new fan and it woulnt kick on ... i wired it up from the connector ... by the time i switch on, it still get over 1/2 and climbs up to 3/4 and a tid bit over that and stays there ... get 3/4 at idle... im pretty sure its the rad cap as ive change the thermostat yesterday when i putted the head back on ... making sure i wont ever use fail safe one anymore ... those engine better stay close than stay open... anyway as its new im putting aside the thermostat issue for now... i wish i could put on the intercooler right now

might help a lot too ...

si its not the rad cap ... i bought one 16psi new ... putted it on ... same thing but seems like its keeping a little bit under the 3/4 now .. if i floor it , it goes again over the 3/4 marks...i got the rocker ajusted right in the mean time .. runs much smoother than wath it was used to.. hope its only a matter of intercooling right now it runs so strong !! in a blink, you go from 110kmh to 145-150kmh in 4th..

it just makes my day

My fan kicks on at about 2/3 hot. Then it cools back down to 1/2 and the fan turns off. During the hot weather last week, the engine was running at 3/4 hot (with ac on). Added about 2 cups of water and wa-la, back to normal.
