PROBLEM FIXED...for all those wondering timing belt jumped 4 teeth!!!!!!!!!!!!!.....yes i know i dont believe it either...but sure enough we took it apart and bam it was all out...put it back together and she is beautiful!!!!!!!!!!!!!!!1
hi guys
ive got an rb20det r32
it was non turbo auto and is now manual turbo...
everything was going fine...would fry the tyres without any trouble at all!
one day i was driving along and hit a massive bump in the road...
ever since the car has completely changed
its started to miss straight away.....throughout the whole rev range
idle is absolutely disgusting...just missing and rough as...and the worse problem is the car has 0! power....a charade would flog the pants off me...it drives and sounds EXACTLY like and naturally aspirated rb20..deep and throaty sound
BUT ALSO pings like nothing else from about 4k onwards
list of things we have tried
changed cas
changed ignitor
changed coilpacks
changed knock sensor
changed o2 sensor
changed ecu
changed afm
changed plugs
wiggled all wires on the car and it made not difference
inspected turbo
pulled exhaust off
tested fuel pressure
checked boost pressure is running 8psi which it should be
now a couple of weird things!
i retarded the timing as far a it could go...this stopped the pinging a little bit...and allowed the car to rev smoothly...but still is the slowest rb20det on this planet
the only thing we can think of now is that the timing belt jumped a tooth or something ridiculous
does anybody know anything else to try
symptoms again are
VERY slow
pinging
missing
very rough idle
sounds like an NA rb20
car is quieter now to i might add
