December 13, 201510 yr im thinking of upgrading my tdo4 turbo on my wrx for an sti tdo5 but was wondering if the existing manifold would still fit and the turbo would just bolt on or would i have to buy an sti manifold to fit i know ill have to get the car mapped once the new turbo is fitted i would just like to know the amount of parts and work needed to make it fit Many thanks Aden
December 13, 201510 yr Same manifold will fit and it will need a remap at the earliest time possible. DONT boost the car with it unmapped to the td05 as you'll damage your engine. Smudger's IPhone
December 13, 201510 yr Author cheers for the advice i knew it would need a remap once the turbo was fitted i just wasn't sure if the manifold would fit, thanks for clearing that up for me Live Long and Prosper Aden
January 12, 201610 yr Author do any of you guys know what sort of power gains i would see from a tdo5 conversion after its been mapped with the turbo a 3" exhaust system and a 255lph walbro fuel pump?
January 12, 201610 yr Author thanks for the estimate ill just have to wait until its dyno'd to see what i get from it do you guys have any recommendations about what lph fuel pump i should go for to go with the standard injectors on my wrx or should i just get the wolbro 255 ph pump?
January 12, 201610 yr If your changing the turbo and getting it mapped check if your year of wrx has a pre cat in the upipe. As the sti or aftermarket up pipes don't have the pre cat in and are less restrictive
January 13, 201610 yr Author ill be decatting my exhaust when i upgrade the exhaust system to a 3" system so ill have to get the lambada sensors switched off by the ecu when it gets mapped what fuel pump would you guys recommend?
