Looking to swap in a SR...what is the stock type performance really?

So injectors, maf...with the stock ecu handle that or is that tuning time?

thats the n00b mistake i made back in the day, installed an S15 spec-r turbo thinking because it bolts in that it wouldnt require tuning. YEAH RIGHT

anytime you make a change, you need to have your car tuned properly. turbo isnt an intake, exhaust or header.. its a fucking turbo. every RPM the motor is tuned for a certain amount of fuel and air, and the turbo changes the ENTIRE equation.

my car still ran, but it didnt create any top end power and needed tuning. lesson: get your car tuned properly after changing turbos.
