is 320cc rc injector big enough for a t3/t4 turbo on a stock b16a.. with low boost??

 

They aren't big enough...I mean, 310's are only good for 220 or so. 310's come with the greddy 19t sohc kits if that's any indication. How much power do you want and what's "low boost" gonna be?

 

probably around 6psi tops 8 racing maybe

 

310cc 200~220whp
370cc 220~280whp
440cc 280~330whp
550cc 330whp~380whp
660cc 380whp~425whp
720cc 425whp~475whp
880cc 475whp~525whp
980cc 525whp~600whp

You'll want 440's at least, but 550's will give you some room to up the boost. I would go for the 550's.

 

thanx.. with 550 do you think i will be straight with a stock pump

 

I would get a Walbro 255lph pump just to be safe. They are only like $100 bucks and you can get one from a sponsor on here.
