Hey Stevo welcome back,
Good to see you back in the Skyline game (even if it is only an R33).
JJR coolers are fine if youre not looking to make huge HP, I use one on mine and it flows great...
With any front mount youre going to have to do some modifying.
For a good all round bolt on kit though, you cant go past the Blitz kits, they're really high quality and bolt on, but they're not cheap.
If you need a hand with anything on your new ride, you know that Luke and I are happy to help mate.
Cheers
Mick
