what size injectors

[joshs1074]

i am building a 90 laser built to run aprox 350 to 400 hp stock injectors wont get me there. i dont want to go to big but big enough what do you think

Well an AFC will spport 650s and lower. Any injector size bigger than 650cc you will need link,keydrive, or some sort of way to tell the ecu you have bigger injectors.

780s I think would work fine with a bolt on 50 trim. That would be the best bang for your buck and you would be on pump gas.

I used 560's (evo8) evo 3 16g and 2g maf will get you around 350 at wheels on 25psi, and you pretty much don't have to tune it. I just leaned mine out till I got some knock then bumped it up a hair. AFC's will run up to 720's I use it to run my 680's (they are for sale) with no problems at all.

I havea stage 3 keydrive for sale set for 780cc injectors and 2 stepa dn all that jazz, comes with the chip, afc, and injectors.

I'd go with DSMlink, and dsmlink can scale big injectors to run like stock, so why go small and have to upgrade again in the future? The jump from 750cc to 950s is only 35 bucks, not too bad IMO. OR you can get FIC 850s from our site for only 10 dollars more over 750s. Best move IMO as they should hold you over for a long time without ever having to upgrade in your power level range; and it still leaves you with some room to grow!

Go with DSMlink and 1000cc+ injectors, so you don't ever have to worry about going bigger if you decide to upgrade.

there goes my sale, o well dsmlink is the best choice

Or you could sell your SAFC. Get use DSmap with your eprom and 1000cc injectors. Then you wont have to upgrade and it will save you much more money over DSMlink or the SAFC/Maft combo.

you really need to move up to a 2g maf anyways. you can get a set of 560's dirt cheap and a 2g maf for like $50. So for approx $125 you can support 350whp. also need fp and fpr though.
