Are you shitting me? You're going to run them AEM EMS for 5 psi? Wow.........what a waste of money. I say get some dsm 450cc injectors off ebay for like $70 or so.

yeah... some h22 injectors are pritty large stock.. and wouldnt probably max out on just 5 psi.. buuuut.. better safe then sorry... get some cheap DSM's

 

How much power are you eventually planning to run? Might as well just get big injectors that will be able to support your power goals, so you only have to buy them once. I wouldn't boost on stock injectors if you don't have to.

yeah, i never even thought of that... if your planning on cranking up the boost in the future ... maybe after you build your block or something then you might as well bet bigger injectors now and tune them down so that you dont have to buy 2 sets... however, the big injectors in my opinion are a little more difficult to tune up right but i tought myself how to use uberdata and it took a while haha.. good luck man...

 

I would say get some 1600cc injectors, never hurts to plan for the future (800 hp). H22's seem to love boost.

 

Lol, I was thinking more like 800cc since they are around the same price as 440cc injectors.

Listen to this guy ..

Figure out your power goals and select an injector from there. For most wild street turbo setups, RC 750 are popular and work great. Dont blow money on 450s, then move up to 550s then decide you want more power and trash them both for 750s.

 

after i get the motor broke in i want to boost to like 12-15 psi what injectors 750cc ,1000 or 1600 cc injector thanks guys

 

I'm using 750s with as much as 17 lbs from a GT30. I plan on upping it to 1000s and doing 20 +lbs. At 16 lbs. the engine develops over 425 whp on Mustang and Dynojet dynos. Should be more than enough (useable) street power - but what's enough?

Mahle makes a piston that is compatable with stock liners.

 

i have ross pistons and crower rods

 

dont get 1600cc, you'll never need them. and there hard to control. just get a set of 660's or 720's youll still have plenty or fuel to give
