piece of sr20 is overheating and missing WTF - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

DailyDrivenS14 · 05-03-2010, 09:31 PM

just swapped the engine
s14 sr20det into s13 chassis
aluminum radiator with TWO FANS one pushing air from the front and one pulling air from the engine side!
Brand new temp sensors!
Temperature in instrument panel shows perfect (slightly below halfway up)
missing while under steady easy throttle (approximately 15% if i had to guess) and is basically smoothe when accelerating and building boost
Damn thing is blowing out coolant randomly when driving (i baby the car around town)
coolant IS circulating when warm so I ASSUME the thermostat is good...???

PLEASE HELP BEFORE I SET THIS THING ON FIRE!

any ideas...? they would be greatly appreciated!

So it misfires at like 15% throttle, but when you crack it to like 30-40% to start spooling its fine? Or vice versa?

at low throttle it misses, under slightly heavier throttle up to wide open it does not miss. bass ackwards from what im used to seeing lol (oh and by the way it has BRAND NEW BKR7EIX's in it and is still doing it) i put it in time and i think i did it correctly, could that be an isssue?

ignitor issue maybe?

Torque the head down again. The fuck if I know.

If your blowing coolant out the cap and overheating... yeah.
