Do I need to change my maf sensor and why if I do and why if I dont?

Will my stock drivetrain hold up?

Also anything I should add?

 

your stock maf sensor should be fine. Just depends since im sure the maf sensor on an evo 4 is probably more restricted im sure you can run a different type of system without going standalone that will allow you to run enough air into that big turbo. Seems like your going to be pushing a good amount of power so drivetrain should be fine but after launches and what not it might need to be addressed in the future.

everything looks fine other than i didnt see injectors? will you be running race gas or pump

 

Ok injectors are PTE 1200

Gas will be panamanian pump gas which is 90 octane plus torco octane booster which should make it around 95 oct and c16 race fuel.

 

any other suggestions from anyone else

 

how much hp are you looking for? if it were me i would add a ported intake manifold and throttle body and maybe a double pumper.

 

I am hoping to make 500-575 pump and want to get the DW 300 pump or modify my walboro.

650 whp on C16

also found out the turbo is a PTE 6235R
