Please Help Diagnosing, Possible Engine Failure!

[BaysideBlue]

I think my engine is f**ked! While driving home last night, heared a thump noise from the engine bay when I gave it a little gas in first gear. would've been less than 5000rpm. Few seconds later felt loss of power, accelerate pedal not responding. So I pulled over, shut the engine and started it again. Engine starts fine but revs not idling stable, up and down from 100-900rpm. Tried to drive a few metres down the road the car started choking, rocking back and forth like a bad clutch engagement. Felt like the car couldn't go faster than 10km/h and will eventually stall. Good thing I was close to home by then so I parked the car on the spot only a block away from my house.

Car was warmed up when it happened, had been driving for at least 15mins. I don't think its turbo failure as I have an aftermarket trust turbo.

What do you guys think went wrong? I never had a engine failure before so I have no idea what was the problem.

Appreciated.

Could be intercooler piping come loose.

[R31Nismoid]

i think youve hit a small child. stuck in airbox.

[RBwhatever]

yeah the child is causing a huge air restriction.

well what mods have you done to the car apart from the trust turbo....it could possibly be a intercooler hose coming off but it wnt sound like that....more like psssssssst....coz that happens a lot to my r33 damn it...take it to a import specialist and that would be a safe bet

Whenever one of my silicon joiners pops off it sounds like a dull WHUMP followed by a bit of pssst. Sounds works that it actually is. Then drives like a pig depending how big a gap has opened up and as soon as you start to make positive pressure, wants to stall.

+1 for cooler piping.

LOL couldn't find that small child by the time I got back to my car in the morning so it must be intercooler piping I thought. And it was! The pipe popped out from the silicon hose just before the throttle body. Don't understand why it happend but it wasn't as serious as I thought so Im happy.

Thanks heaps fellows. You guys rock

Aother problem. Car is not boosting anymore. Boost gauge not working, car felt like a N/A but I can still hear the turbo spool What's going on?

[r32sky_line]

check the wastegate. Could be stuck open.

[BaysideBlue]
