um what car?

 

even better question what is the set-up?

 

50psi of fuel pressure. RC Engineering 440cc injectors.

Car made 310whp 220tq. Customer was reccommended to change to injectors a little bigger.

Car had full ac, ps and other things. Setup was basically a revhard kid.

If all you want is 300, get 440s. If you are buying new, I'd recommend for you to get some 550s.

 

550's seem to be the norm these days. I would assume you could skate with the 440's if you don't have any plans to make more power.

 

get a bigger cc then what you need, then you can just tune them back..granted they will cost more, youll never need to upgrade should you decide to want more power.

i'd go with 1000cc

 

440 or 550.... just make sure you get it tuned. What kills your gas mileage is not having a tune.....

 

b20b 9:6:1 or 9:2:1 compression with basic t3/t4 kit ... thinking about letting inline pro handle it all .. but i havnt found out what they would want to do it ... if its over 2500 then ill do it myself and have them or some one off the site tune it .. might go 550 dunno seems big tho dont wana guzzle gas.

 

tunertoys $250 shipped on 660cc

 

Used RX-7 550ccs 80 bucks? Seriously though.. you think a shop is going to do all your work for under 2500? You better be providing the materials.
