Hi guys, my freinds got an R33 GTR. I'll start from the start..
He was driving along, all of a sudden, no boost, he didnt hear a pop or loud bang, so im guessing not a boost pipe off
It would run/drive just no boost, as soon as he stopped it, it cut out and it wont start ever since
Ive been to the car today and tried many things; Changed the plugs cos te old ones were goosed!! Still no go, Took the turbo pipe off the turbo side into IC and felt the Suckion, then took the inlet manifold IC pipe and did the same. The both sucked as hard, so i knew he didnt have a boost leak. Its getting spark, and its getting fuel. There's a strage hissing/pulse coming from the back/under the inlet manifold. I took the top Timing Belt cover off, and the belt seem's very slack, so i got the cams lined up, and they were spot on. Is it possible that its jumped a tooth on the crank? i didn't get as far as removing the bottom part of the Timing, its started to rain!!!
It just seems weird that there's fuel and spark, and even with a boost leak, it should run
I had a similar problem on a mates 300ZX, and we disconnected the Air Flow Meter's and it would start but not run over 3000rpm
Any help would be much gratefull!!!
Thanks Dudes
