On the stock twins, to get the most out of the car, I\'d go (in the following order):

Cat back exhaust
Air Intake
Power FC
Decat
Frontpipe
Intercooler
Fuel Pump
Larger Injectors

That will see you near the limit of the stock twins - >350bhp at least.

However, After the PFC you will need a remap for most of those mods, so it may be wise to fit them all at once and get it mapped to save getting the map continuously tweaked.

Apexi Power FC is the mappable ECU, you will need someone who can map it, try the //www.rx7club.com forum as there are few guys from your country who post on there and do tuning on the rx7
