I know this is prolly just a honda forum, seeing how no one has posted anything but honda's but maybe you will be able to help me out. I have a MR2 Non-turbo but I just got my hands on a RH5b IHI turbo. I'm looking to run about 9psi but im stumped on what type of fuel managment I should be using? What injectors along with anythign else do you recommend?

 

you'd be better off searching for a mr2 club on the net. Mind you Im sure you can get some answers.

 

S-AFC is good for 9 psi.
I don't know what kind of injectors you got, but try to find the Mr2 turbo they are 440cc injectors or DSM turbo injectors they are 450cc.
These things will be enough to get you to 9 psi.

 

I am not sure if it will work but you might want to convert your mr2 to the turbo ecu and grab the injectors off of a turbo mr2(440cc i think) or you could try 450's with the afc hack although your numebrs are gonna be different form the honda ppl useing the afc on this forum. AS for the ECU from a MR2 turbo i am pretty sure there are lots of chips or piggy back ecu's availibe for the mr2.
