For everyone info, technically according to the paperwork, you can go from a NA 2L to a Turbo 2L & still have the same RAC horsepower as it calculated

RAC HP = (bore size inches) x (bore size inches)x cylinders/2.5

Horsepower - Wikipedia, the free encyclopedia

Bore size is same for 2L NA & Turbo. 2L EJ20 & EJ20T with bore size of 92mm gives a RAC HP of 21. Not much is it!

Strubaru & dtrally, have you guys done a direct engine replacement before?
