If someone could give me a list of What's needed to do it that would be great [emoji2]

What are your power goals?

What are your skills and capabilities? Can you do fabrication and welding? In other words what could you make yourself and what would you need made?
How about wiring and tuning?

I wouldn't have a exact power figure
As you said in a previous post it's better to Turbo
My mechanic would be doing all the work and he reckons it'll cost 5000 euro which is $5600 dollars for labour and parts but he said I'll have around 300 bhp

Choosing a ballpark power goal is the first thing you need to do. Different builds will have different part requirements. Spending the money to build a 500 hp motor then only push it to 200 would not only be a waste of money but would give you a less efficient motor than if it was built for say 250 hp.

For much over 250 CHP I would definitely replace pistons. For less than that you could get away with all stock internals with a real good tune and proper supporting mods.
With good pistons you should be able to hit 300 with the stock cams but personally I am more fond of running more cam and more compression. I would run a 264 to 272 cam with about 10.5:1 compression. More cam and more compression means more power per PSI so less boost to reach your goals. This means you can run a smaller quicker turbo and also lower intake temps.
Higher compression and lower boost also means you will get better gas mileage, will have better off boost power, smoother transition to boost and will hit full boost faster.


For a 300 hp build and for someone else to do all the work $5600 sounds like the right ballpark. If you did everything except for the machining yourself you could probably do it for almost half that.
