I have a 98 type R. Standard apart from a APEXI Power FC and HKS SSQV.

I have ordered a Ninja decat downpipe and Walbro fuel pump as I just wanted some more torque.

Will I be OK with just the fuel pump fitted and a re-map or do I need to upgrade injectors and fuel pressure regulator?

thanks.

 

downpipe will give you more torque and it will spool sooner..

You should see a reasonable improvement without injectors.. depending on the car you may have enough fuel to get as much as possible out of the set up once mapped.
