Ok so I'm aiming to upgrade the power of the car to KO4 turbo power and fuelling etc.

The list below is my start for what I think I will need. If anyone can help by adding to it I'd be very grateful.

Cheers

1. KO4 turbo

2. Fuel rail

3. 4 bar 'in tank' fuel pump

4. Injectors

5. 4 bar fuel pressure regulator

Also nice to have would be uprated clutch and a front mounted intercooler along with obviously a remap.

My car is a 2003 Vrs btw

You'll also need:

Manifold

Coolant and oil feed and returns, these are different to K03S.

Support bracket for turbo

Downpipe and some sort of cat/by pass and reducer connector for exhaust if using standard system

Turbo inlet pipe, original rubber or aftermarket silicone version

3" Maf housing + air box or aftermarket filter

Upgraded intercooler and revised tubing routing

Remap

That should do it

If you can get a KO4-001 its a straight fit to your existing manifold and oil lines etc..

But dont run as much power afaik
