do i need bigger injectors

[lnewton1974]

I have a 99 eclipse with a 20g turbo, front mount, k&n air intake, injen intake pipe, knkock off greddy type bov, aem wide band gauge, boost controller and i believe i do have a walbro 255 fuel pump, and fic550cc injectors. I guess my qustion is do i need bigger injectors cause i was told to get bigger ones, any help is really needed. Thanks

Or, the smart thing : Turn the boost down.

Also he could of tried doing a boost leak test, replacing plugs/wires, checking coil pack, SEARCHING.....and probably a little more searching.

500 hp

I had my car tuned with a 50-trim and 680cc injectors by method of Chip Burning. I was running 22 psi, now i have 1000cc injectors and am waiting my turn in line for 25psi with kelford 272s.
My suggestion is if your not going to be heavily modding the car go with the precision 680cc injectors. They treated me very well.

I completely agree w/ Rory. Need some tuning software man. I think the 1200's are a little excessive for 500. Maybe some 9-1000cc's

500 hp

500hp to the crank or to the wheels? They are 2 completely different numbers. 500hp to the crank is about 425-450 to the wheels (i forget what the % loss is but that's a 15%-10% loss which i think may be low). 1000s will be good for 500 crank 500 to the wheels you may want to go higher.

I'm running the evo 3 16g and I'm running FIC 950cc's. So if I were you I would go a little bigger just so you have more room to grow.

550 should be enough with the 20g and neo, check all your plugs and wire for it being cut out at 4500-5000k. later when you get link or flash, buy 1000cc, so you don't have to buy twice. plus 255 rewired. set yiour afpr to base psi and try to fix your cut out at the time being. fowl plugs cut out in high rpm.

Build your bottom end, get a Balance shaft eliminator kit, strong clutch (along the lines of an ACT 2600), a lightweight flywheel and if you have the money maybe a butchered crank. Get your rotating mass down (how much resistance the motor has to use (hp) to get the car moving). As always get the overall car's weight down too.
