Hi,

I recently purchased a VF-35 to put onto my JDM STI IV. I purchased the VF-35 as it has similar low end characteristics to the VF-24, but also doesn't die out around 7000RPM. Does anyone know if I will have to re-map the ECU to work with this turbo when I put it on?

--engine is using stock sti injectors, yellow I think and stock ecu boost control.

Thanks, Greg

The VF35 has a small exhaust housing than the VF24 (P15 vs P18) so it will probably spool up a little earlier. Hopefully your ECU should catch it but you may have to look at alternative boost control if not. Also fit something to monitor for knock - using a smaller turbine housing (all other things being equal - which they are not unfortunately) results in higher exhaust back pressure especially at high RPM, the result of this is more likelihood of detonation.

Hi,

I'll be sure to invest into a knock link or something similar before bolting the VF35 on.

Thanks, Greg
