Anyway...
First off, I am no car-dummy but I recently totaled my 300zx and I am now looking at a 91 Supra Turbo. However, the engine knocks and it appears to be coming directly on top of the valves. It is an inconsistant knock but seems to knock more than not knock. It doesn't appear to be the valves cuz the knocking is too deep and throaty for valves. With this being said and the fact I've never owned anything turbo, the only other thing I can think of is A) the turbo is making the knocking noise or B) it's about ready to blow a rod.
Overall, the car is not in that bad of shape for a 15 year old vehicle. It has 176k on the body and the seller claims they have paperwork showing the engine rebuilt at 100k and a new clutch 7k ago.
If indeed the engine is gone, what kind of price is a guy looking at to have the engine rebuilt on one of these bad boyz? Maybe I'll just keep looking for another Z.
If anybody can stop laughing long enough to give me some honest input, I'd gladly appreciate it. Maybe you could be an assistant in converting a Z-guy over to a Supra-man
TIA, I look forward to your input.
