R33 Gts-t Rb25de Turbo Installation Gone Wrong

[samismyhero]

Chucked a Turbo into my 1994 R33 GTS-T RB25DE.

Whenever I hit the boost at like 0.5bar for more than a second, the whole car jumps and the turbo drops out to -0.5

One friend said I need a new Fuel Pump that can handle the Turbo as the RB25DE Fuel Pump isn't giving it enough fuel.

Another friend says it's my Fuel Compression Ratio, what should my ratio be and how should I check it?

Any ideas?

(Spark Plugs and Coil Packs are fine)

What ECU are you running?

What ECU are you running?

I'm not sure what ECU I'm running, I'm not as knowledgable as I probably should be about engines.

It wasn't actually me that installed the turbo, it was the previous owner, I'm not sure what modifications he made to it after putting in the turbo.

If it were me I'd be starting ground up.

Get a list of everything you know is in the car.

Then get a list of things you dont know about i.e. ECU etc etc

It will be easier to get help if you know whats what - as opposed to guessing.

But I would be taking it to your mechanic as it doesnt sound fuel related more electronics.

My 2 cents...
