740cc injectors?

Guys check this out i got a 98 240sx that i am dropping an sr20det into, but i don't just want to stop there i want to upgrade the turbo, ecu, and injectors. I found an ecu programed for 740cc injectors, and i found the injectors now the only thing i am wondering about is what kind of a turbo would best suite that set up and will that engine with all stock internals hold up with that set up?

That engine can hold up to 400 hp I've heard and read. it can take 20 psi or maybe a bit more.
I would go with a SC61 or a T3/T04E AR .63 turbin with a big trim maybe 57 or 60??

the sr20 motors are from the Silvia's and the RB20,25,26 are from the skyline.

SR20's are 4 cylinders, RB's are 6

Re:740cc injectors?

if your aim is 20psi or a little more, the mitsubishi 16g would not only be the cheapest choice, but also the most driveable. they tend to spool faster then garretts, and their efficiency is still in the 65-70% range even in the higher pressure ratios. if you have a decent intercooler, it will MORE than make up for any differences in compressor efficiency between the huge garretts and the mitsu.

my eventual goal with my MR2 is about 22psi/~320rwhp, and the 16g is the perfect turbo to do it, as long as i don't want to go any higher..
