i have a 2002 jdm wrx , ive just bought a td05 instead of the td04 do i need injectors and remap or can i fit sti inj's and sti ecu ?

 

You will need a remap if you change the turbo and injectors.

 

You will need the injectors, uprated fuel pump and a remap minimum (you also dont get the 4 pots standard, JDM wrx's of this year have 2 pots which suck )

yeh ive upgraded to 4 pots now could i fit td05 sti inj's and sti ecu , and not need a remap

 

No fella, you could not.

 

could i just fit the td05 and not need a remap on my jdm

 

Not really mate.For the most part these engines need mapping when you change pretty much anything.You can't just bolt stuff on.This is one of the reasons you see a lot of blown engine threads.
For just bolting stuff on you can change a cat back system,panel filter and fuel pump.
Pretty much anything else needs mapping to suit.

 

ok.. ive done pump ,turbo back s/s and pannal filter , and have this to05 but if i fit it i would need a remap ? bob rawl wants £650

 

I know it sounds expensive,but I'm pretty sure that after you're first mapping session it becomes cheaper.So if you want to change something else in the future I think it only costs around £150.Someone correct me if I'm wrong.
I haven't had mine done yet so I'm running pretty much standard but you will feel relieved after its done.
The other plus to having it mapped is because you've only got access to 97 Ron fuel,he will map it for that fuel.

 

mate the cost of a remap vs the cost of a new engine.

a guy on here was on his 4th engine within a few months of each other. The problem was because he didn't use a base map as he thought that by fitting engines from the same year was fine.

Just get a remap and make the most of the mods on your car. You will love it more.
