how much boost can stock 275cc injectors handle from a evo 16g turbo

b series injctors are only 240cc and you could do 10 psi on a fmu no probs.

it's for a 00 Eclipse and the stock injectors are 275cc,but thanks we are gonna try 12psi and go from there

With an FMU yes, but you put much strain on the rest of the fuel system. Larger injectors are always the best bet. And if its an eclipse, couldnt you just use the older 450's with resistors?? Im sure they fit.

we got everything worked out guys,thanks

I'll post Dyno charts when we go to tune it,we are looking for 300whp at 11psi

sounds like it made decent numbers.

96civic3door · 01-03-2005, 11:42 PM

we have not dyno'd it or put the turbo on yet,these are just numbers we expect/or hope for.

I did not know that the engines in the eclipse's were so stout untill he told me......should be coo to see what it does

i ran 14.2psi on a stok evo was good no probs

PM-Performance · 01-04-2005, 11:40 AM

stock evo's run 17-19psi. i dont think thats what he's asking . he is asking how much boost on that size injectors is safe. and all in all it really depends on HP not the boost. i dont think those things will be safe for 300whp.

96civic3door · 01-04-2005, 12:00 PM

it's coo he has RC 450's standing by just incase

PM-Performance · 01-04-2005, 12:19 PM

id put them in before you even try to dyno it. you can always down tune if needed. if your maxed out on the others, you cant up tune, and is it worth blowing an engine?

96civic3door · 01-04-2005, 12:41 PM

he is having a problem with his e-manage(please dont say to get different fuel management) and the car developes a tic in the head with the 450's,but when the fuel is backed back down to say around 330cc's or so it does fine

non-honda question

the tic(I dont want to call it a knock cause it aint) is above the number 2 cyl. when it happens

a stok evo 5 runs 12psi not 17or19 had 1 for 2years m8
