i've just bought a 1994 rx7 rs with the following mods


New Rotor Housings
New Plates.
All Ported
HKS T04E single turbo Kit
Greddy Front Mounted Intercooler
Greddy Elbow Pipe
HKS SQV Dump valve
Greddy Front Strut Bar
Full Stainless performance exhaust
Cat Replacement Pipe
1300CC secondary injectors
Uprated Bosch Fuel Pump (in tank)
Apexi Power FC
Apexi Power FC Commander
Blitz Boost Controller Spec R

Air Pump removed.
Vacuum Nest Removed

any advice on where to go next? i was thinking maybe water injection so i can up the boost (0.8 at the moment) or maybe some sort of brake upgrade, but in all honesty i'm new to all of this and theres so many products out there i'm not sure what to do.

 

Light weight flywheel? Big break kit would be an idea.

 

If you ask me it depends on your own understanding of how our cars work. You seem to have a pretty good amount of mods right now. I would recommend a wideband and a Datalogit, along with a good tune to assure that all your fuel & boost mods are tuned properly.

 

Run it for a while as it is, doing only maintenance. You need to know the car well and have it very well sorted before adding more mods. Plus there is probably plenty of maintenance to do - coolant hoses, fluid changes, fuel filter, etc.
