diference between sti and sti help
 

what is the diference between a 2002 wrx and a 2002 sti , is it just turbo injectors and ecu

Engine, gearbox, intercooler, brakes, interior, suspension etc etc etc.....They loook the same-ish but different animals.

lol :)

Why do you want to know?

i have a 2002 wrx jdm , and am going to fit a td05 , and want to know if i fit the td05 and sti pinks and stiu ecu woud it be ok or woud i need a remap anyway

or could i just fit the td05 on my jdm

Best bet is to fit the td05 and sti pinks and just get a remap, sti ecu wont be suitable, as it's an import may be mapped for uk fuel so ecu might be licensed already so a cheapish fix, if not go open ecu

As above really, Fit turbo, injectors and map it, The ECU might be able to be used as the JDM WRX also has AVCS like the sti so the ECU must have the featues built in, But the problem is that any Newage scooby ECU will have the OEM map for a VF30 or VF35 not a TD series of turbos so it would need mapping anyway
