oh ok. is it hard to wire in?

I gave you the link on how to do it. Seach on Honda-Tech for a write up. Ive never done it.

oh i didint c tha link sorrie. if i did 450s would that cause any problems tho? like i said i can get a good deal on them

its all in the tune.
my buddy has 880's on his turbo civic making 420 and his car runs fine.

I seriously think 450's are over kill, but its good to get a large injectors, you can also tune them down (less duty cycle) when you tune. however, if you have too small of an injector you can not increase their output via tuning... once you max out your injectors you have one option, go bigger.

cliffs -

450s will run fine.
450's are too big IMO. i think you should run 390'sw.

well ill keep my eye out for 390s then. i dont plan on going much higher then 13 psi anyway. what other things do i need to do to prepare for a turbo. im going to be runing 10psi on stock engine

440's arent too big go for those if you can get a deal on em....

390's will only support 200-230 hp depending on fuel pressure, 440's will get you in the 250 range

i mean i dont wana waist my money on sumn i dont need but they are like 100 shipped on ebay. thats not bad for 4 450 injectors. my hp hopes is round 250

if you want 250 whp then 390s will be really really maxed the F$#@ out to get you there. use that link i posted earler and remember that is crank hp not wheel hp.

your not going to run into problems with idling on large injectors unless your like 800cc plus so theres really no penalty in buying big.

my friends turbo LS has like 700cc injectors in it and its only making 220whp

ok cool. ill probly stick with the 450s then. what else do i need to do to prepare for the turbo besides injectors?

a good EMS with datalogging and a wideband.

I'm using rc 310 on only 9lbs I made 210hp with a slipping clutch and the 310 are maxed out..

thats not bad at all man. do i need to do any spark upgrades to run 10 psi?

just run the one step colder ngk plugs you can get then on the jackson racing web site

ok. no external coil? also what bout a fuel pump? just wana make sure im doing it right

fuel pumps not a bad idea depending on your chassis (some civics have smaller pumps than integras). the thing to know with the fuel pump is that higher base fuel pressures reduce the amount of fuel flow the pump can support. running larger injectors at lower pressures helps avoid this.

as far as your ignition system just leave it stock (change the plugs though) you dont need to worry about that stuff till your makin some pretty serious power.
