Is this the best way to go turbo wise? To avoid having to use a a different turbo manifold.
Also, an exhaust setup is also a must.
Are there any full exhaust with down pipe that are good?
Or do I need a custom one to be made?
So the basic here is hybrid turbo, downpipe, exhaust and have it custom mapped.
Do I need to swap injectors? If so, to which ones?
And with new injectors, is a new fuel pump necessary?
Anything else needed?
Thanks.

Yeh a hybrid turbo would be a good way to go to get an extra bit out of that turbo ... but unsure if you will hit your desired 300bhp band with a hybrid? sounds like you might need a bigger turbo. I dont really know much on these cars, they are the 200bhp?
As you mentioned a full exhaust system is a must, an I would probably go for a custom system. Get it made to how you would like it.
I cannot say anything on the injectrs / fuel pump as I dont know their limitations. Just modded my S40 T5 from around 290bhp to hoping 400+bhp but upgraded the injectors and fuel pump as well. I know the factory fuel pumps could be could for a lot more but how long it will last, will be another question.
Probably another thing to think about is your handling, hunting big gains without tackling the handling problems will make it worse to drive.
Few other things to think about
:
- Limited slip diff
- Wider tires
- Coilovers (to help cornering and control the body of the car)
- Bigger brakes
You should probably do some research into your block \ pistons and rods? and its safe limits?

These guys should know more about your car and engine, quite a few T4 owners there that have modded their cars.
