Hey Guys,
Finished my turbo conversion and car isn't running properly. The car idles fine, possibly a little high, but when I drive it and put the foot down, the turbo spools up quickly, but the engine bogs down and the car barely goes anywhere..
I can only drive the car on the tiniest bit of throttle, at around 30km/h. I have a new TPS and thought maybe it isn't calibrated properly yet, but unplugged the thing and made no difference. I am possibly thinking vacuum leak, which could account for both the bad driving and slightly high idle, but wondering if there are any other possibilities??
Cheers
Hugh

There could be a boost leak somewhere, check all your piping and hoseclamps and make sure no pipes have blown off the plenum.
you need to give a bit more info about your setup, are you running turbo injectors and ecu?
If its running rich it would be blowing black smoke aswell have a look for that.

Sorry man...Nah still high comp...running turbo injectors and turbo ecu, does smell a little rich...I've had a bit of trouble with the timing..I've installed the dizzy a couple of times with the rotor button lined up and completely horizontal, pointing at the radiator, but when I put a timing light on it, it says the car is 10 degrees advanced, which is where I want it, but the dizzy is fully advanced at the adjuster bolt, whereas I think, it should closer to in the middle of the adjustment slot..
Car was fine before the conversion, although, that was a while ago..It's been a slow project as I haven't had much time and have done a lot more to the car apart from just the turbo conversion...
To me, it doesn't sound at all like a head gasket, but others may know different, I'm no expert..

that cant be right! u cant have 10deg of timing when the dizzy is fully advanced...
id be gettn that checkd first thing.
sounds like u have set the timing wrong
if u get it looked at and thats still not the problem, try the next thing, but do it 1 thing at a time. as its easyr to find the problem.
