ok im just curious im concidering upgradeing my turbo but im not quite sure on what all exactly i would need to do to make it work on my s13 sr... i know you need a new converson bracket and do you need new injectors? whats the min you can run 3's or would i have to go like 550? also you would have to get a tune correct?? how much is the avg tune for the sort of upgrade?? basicly i want to put a s15 t-28 on my s13 sr ... and also is there a cheaper way to do something like this could i just use an s14 turbo?? i dont know much about doing this but anyways thanks

 

stock SR injectors are 370cc injectors, I run 550cc sard injectors a Z32 MAFS and a tune. I dont run coolant lines, because T25 lines do NOT fit. you will also need the s15 oil return however you can rig the T25 return to fit. Dont cut corners and you'll be fine. Also, why are you talking upgrade wasnt your motor on its way out??

 

I would do some research... There are multiple forums that has this question asked a bijillion times. We can't hold your hand. But 4wheel has directed you down a very narrow but straight path, you should run with it.

 

it is but i have another motor now im just curious
