View Full Version : SR20 redtop pop/bang from turbo area

02-14-2012, 12:01 AM
k so i was driving home and when i was going up a hill after i let off the gas my engine popped. it does this everynow and then but its from the tailpipe, this noise was from in front of me.

at first i thought it was like a boost hose had come off but that didnt make any sense and then i went to blown turbo

now my buddy when driving behind me earlier was saying i think ur burning oil and it kinda smelt like oil burning but very subtle, but this has always been around in varying amount and i thought it was just cuz the engine has like 200k on it. there was no cloud behind me, idle was fine (nothing changed) was still getting power, mind u i wasnt pushing hard after the noise only like 1-2 psi if that, and there was no oil dripping anywhere. the turbo sound just a tad funny like instead of the sshhhhh kinda sound it was like 80% shhh and 20% supercharger whine.

could this be caused by a blown elbow gasket or something like that or should i be looking for a new turbo

any info/ ways of diagnosing this is greatly appreciated and much needed

sr20det redtop stock almost everything except front mount

im prob being a whiny b&tch but i only just got this thing running again

Just curious if you found out what it was? I may be having a similar problem.
Thank you in advance.

turbo is on the way out, rebuild it or replace it with a better turbo, disco potato or 2871rs.
There is a chance that a gasket let go on the elbow, but there would be a flutter/ticking sound
answer will be no different here then it was on BC240 dude.
