JDM 93 wrx jerky boost
Hi, I just picked up myself a 1993 WRX (GC8) imported from Japan. Runs really good (except high rpm boost obviously). Just needs new belts and has a jerky boost issue. I searched but couldn't find anything besides possible fuel not being high enough octane(got 92 in it) and possible boost leak is what I was thinking.
When the car is under full boost and at about 5k rpm and up the car becomes all jerky. Jerky is the best word I can think of. Like the boost comes and goes real fast above that RPM. Doesn't matter what gear the car is in. The clutch is good I am pretty sure. Doesn't slip and doesn't smell. The turbo pulls really strong still up to that time.
Sorry, never owned a Subaru. Have a 2000 Honda Prelude and just sold my 1991 GT-FOUR RC. Help would be greatly appreciated, thx in advance.
