I feel like a blown headgasket is the go to diagnostic of these cars. I was told very much the same many years ago and it was a split water pipe and a dodgy MAF sensor. Took about 10 minutes for someone with knowledge to diagnose.
The best specialist in the country isn’t far from the places you’re taking. I also would assume that you must of paid more than tuppence for the car as they aren’t cheap these days. It’s got to be worth getting an expert to give it the once over. If it is dead, I recon he will even have a good contact for getting rid of that’s the case.

hi im new to forums and im new to the 300zx scene.
i have wanted one for years but have 4 children.
i have recently been able to afford one as i need ti have a family car as well as the new toy.
Im having a few problems tho its a 1990 twin T (auto)
when i accelerate the boost gage goes right up to 7 then drops right back down with no real kick.
the engine doesnt smoke and makes no tapping noises nor overheats
i suspect turbo or vacuum problems as other than this the car drives fine just slower than my 2.0 red top astra :(
any ideas would be apreciated ( already ordered a usb consult cable with software
ta
