Default what size injectors are good for ~300bhp?

im peicing together my turbo kit for my build next month.

I'm boosting my d16z6 with a garrett t3 super 60 (thank god i didnt say ebay, right?)

looking to aim for the above BHP, i expected i'd be needing ~ 440cc size injectors. but for 320$ DAMN, these are expensive,

so i want to be 100% sure these injectors are the closest i need (not looking for more head room afterwards)

and for that matter,

is there ANY possibility i can boost on stock injectors? (their 240cc but with a walbro pump)

even if its a a 50hp gain limit, can i the injectors flow enough for boost?

thanks to all that reply (i did search a little, but we all know how horrible the search function is)

if you want cheap you can pick up the dsm 450cc for under a 100 or 560cc evo injectors for around a 100 also.

dont forget you will need to wire in a resistor box to run these injectors. also you may need to slightly modify the IM seals for the injectors to fit properly. nice way to save a few bucks.

or look into the Tuner Toys saturated injectors. Decently priced and are drop in replacements.

definetly go with the 550 or higher. that way if you wanna boost more(most likely) you dont have to buy bigger injectors. look around. theres alot of good deals. got my rc 750cc for 185 shipped. was cheap becuz it was painted, which i just used paint thinner to take it off. looks like new again.

go with atleast a 550cc injector... if you do end u getting the 450cc's from a dsm you will have to shave down the clip on the inside of the injector(u will find out what im talking about)...there are a bunch of people in the marketplace selling their old set ups... look to see if anyone is selling any injectors
