Ok here go's i had my RB26 built 19000km ago. It has been running well tell last week.
Coming out of a corner i put my foot down and when i let it off the Throttle it stayed reving so i taped it a couple of times. It stop reving i pulled over car sounded like a WRX so i turned if off. Frist thought coils when i went to check this the car wouldnt start. Took it back to the shop which built the motor and they told me that the comp test was 115,120,90,5,0,80 so thats bad. Anyway what would cause this so quick.the shop blamed the head until i said they rebuilt that too. So anyway what ever is wrong with the car was not their fualt LOL.
so could be???
Fuel pump
Rings
head????
what was done to the engine in rebuild
Block was bored, decked and acid bathed
bullet rods
forged pistons
stock crank with jun collar
kings race bearings
N1 oil and water pump
gates timming belt
head has bronze value guides(exhurst side only maybe)
Anyway thats the basics so what would cause the low comp and how dose it happen so qick
Thanks Brad
