Run a vacuum line from the j-pipe (off the turbo) to the wastegate actuator.
That will do nothing but make it run like it should at wastegate spring pressure. The OP says he wants to go lower than stock pressure, right?
Stock boost uses the bcs to make it around 11psi. Wastegate pressure is around 9.
My cars a automatic so it has the 390cc injectors with a nt ecu It had The turbo ecu and it just had checke engine lights so we put a bt ecu I have 2 turbo ones auto the others manual ecu and 1 nt ecu I don't no if I have the turbo pressure regulator I think not sure if they kept it I it the turbo maf in there
That's why I want to turbo it cause I have almost everything I need the car starts fine and goes nice the car has mix of turbo parts already on it when I got the carSo, you want to drop from 9.0:1 NT compression, to 7.8:1 turbo compression.
Either add another HG or change out the pistons.
NT ECU worked great with NT 240 cc injectors - stock injectors for the NT 4G63.
Ya, you're running pig rich with those 390's on an NT ECU.
The car had the turbo taken out it has a lot of turbo parts on it I'm looking at adding 1 g pistons turbo ones obv the cars fine just wanna bring it back to stock without destroying itThe lowest you can technically go is about 8 or 9psi on the stock actuator. They seem to vary a couple PSI occasionally. I'm also having a margin of difficulty trying to understand what it is that you're saying on this post. So it's an NT block that you have the turbo parts for, but you're running Turbo 390cc injectors on an NT ecu? That alone would make the car run like crap.
Look into 2G pistons on 1G rods. That will allow you to keep a little more power under the curve than the lower compression 1G pistons.
ight thanks for the tip might as we'll right hahaNo, as far as I know there is basically no difference between an NT head and a turbo head. I don't see why you would need to 'mill the head' to swap pistons. I'm just commenting on the fact that you were talking about swapping to 1G Turbo pistons. If you're going to go through the trouble to swap pistons at least get better ones than the 1G.
