Ok, in just about every forum i read about turbocharging D-series civics, they tell me that upgraded injectors are necessary so that an appropriate amount of fuel gets into the engine... however, though searching and reading on injector flow rate sites, i learn that a stock D15b7 engine has 240cc injectors, and, if my calculations are right, they should support up to 48hp per cylindar, or 192hp for a 4cylindar engine. If i am only looking for 150-160 hp from a turbo, shouldnt the stock injectors be adequate?

im looking to boost a stock D15b7 with about 4 psi of boost.

i guess but all that money going into a turbo kit y not make at least 200 or try.

Yea they should hold up. i took extra precautions anyway an quickly installed 450's with a gay SMC at first but chipping an ecu is so easy that you shouldn't risk it.

where is a good place to find bigger injectors, ive looked on ebay, and found a few, but i dont know what fits civics, or if they all fit or what?

Take my advise and install bigger injectors while you can. I have seen DSM 450cc injectors selling from $40+ shipped. You will also need a resistor box which you can get at a junkyard for free or mayde $5-$10. Four (4) psi is nothing to talk about, and after a few days driving you are going to want more boost .

Check the for sale forum, ebay, or junk yard for the first generation DSMs.

people on the forsale forum always have injectors for sale. and yea you WILL want to up the boost after a few days of driving.

will just any pair of 450cc injectors fit?

Make sure they are DSM because if they aren't you might get the resistence wrong an getting the clips with them is always a good idea. There is a write up of this in the tech section.

I am in the same boat with a d15b7 the most hp i'm looking for is 200, would injectors off of a d16 or even a b-series work without having to do anything else? i've never heard of it being done maybe there is a reason for it, but it doesnt hurt to ask

---- if you are only runnin 4 psi just get a fmu and then you well be good because 4 psi is nothin and the fmu well help out alot trust me i didnt run with out one for a while and now i did and i makes alot more then you think so good luck
