I've searched and read a lot of the FAQ threads but still have some questions regarding my H22.

right now the car is stock with a generic 3" short intake, 2.25" exhaust and a fidanza flywheel. I do have plans to put the car on the bottle for track use only but that will not happen for a while. I was thinking of upgrading the igintion and fuel system along with sort of tuning system. I can not do it all at once and was wondering what order I should do the mods?

Tuning: I was thinking of using a hondata the only reason for not using it is that fact that I have to buy another ECU, so I was thinking of just going with a VAFC.

Fuel: Replacing the 200k mile fuel pump with a 190lph pump, fuel rail, and regulator.

Ignition: I am kind of lost hear

The exhaust will be replaced but porobably will remain 2.25" with a carsound cat, right now it has a GSR cat.

I am also doing this on a budget, that is why I don't want to buy another ECU and have to the mods step by step.

If it matters the H22 is in a EG.

thanks
