what type of injen CAI did you get for your fd2? im planning to get one but not sure to which one would be right..
The one that is specified for the FD2 from JDM YARD although you need a RBC intake manifold aswell, EG5 on ozhonda sells both items im sure he can help you out. And then there is the other cheaper alternatives such as Simota Carbon Charger 2 intake, but it probably isnt as effective in enchaning performance as Injen.

Ask yourself this - What do you want to do with this car? Before you even buy a mod. Street warrior? Hill climb? Daily driver with some oompf? etc This way you can put things into perspective, and find a better solution to your needs.
Cross between daily and street warrior, i want power but not so much that it significantly affects the longevity and driveabilty of the car.

Hey mate. The best bang for buck mod would be turbo charging your car. But to appreciate the power you should initially do those small mods to mentioned. But don't do them all at once...you'll learn to appreciate each part more this way.
Yeah thats what i had in mind aswell, steadily get the bolt ons installed in the order you mentioned and then go for the forced induction at the end.

Can anyone give me a rough figure on the gains i should expect from all the bolt on i mentioned in my initial post with the piggyback ecu tune ?
Its 114 kw stock, i believe it would reach 130+ kw. Is that hoping to high, or is it reasonable ?

Btw thanks for the feedback guys.
