stock block b18b in eg coupe
going boost next week
im looking for 350-370cc injectors or so, fuel pump and thats all she wrote

only looking for 8-10psi with stock internals on a Garrett T3/TO4E 50 trim w/ .48 or Garrett T3/TO4E 57 trim w/ .48 a/r... whats better? 50 trim or 57 both being .48ar


looking for better with my stock block and fuel upgrades couldn't find a thread on this specific deal so thought i';d ask

 

go with atleast 550cc injectors (they will be good for atlest 350 hp)
and a walbro 255 lph hp pump

as for turbo go with a 57 trim. hands down. ls's dont breath enough for a small turbo to make high rpm power

 

well i understand the get a 57 trim turbo
but 550cc injectors and im aiming at 230-250 horse.. wont these be too much fuel and run it rich?

 

when you get it tuned they will fix it

they say once you go boost you will always want to turn the boost up

 

okay well then if i want to add boost the injectors will be large enough to withstand the more pressure and get a re-tune, correct?

 

never get a fuel injector that will be at full capacity with your initial goals. i can guarantee you will have to spend more money on bigger injectors, in your case even if you wanted 2 more psi of boost.

the car can be programmed to the right amount of fuel when you get it tuned.

i ran the 57 trim .48exhaust on a stock ls motor. 10 psi with both 550cc and then 780cc injectors. it was all in the tuning.

side note: ive probably had 10 different motor/turbo setups and combos over the past 6 years, ranging from 180hp to 425hp+ and by far the most fun setup to drive around was when i had that 57 trim on a stock ls motor in a civic coupe. 10 psi by like 3400rpms, and pulled all the way to 7500. you could even hear it spooling up through the exhaust like a jet lol.

 

blackeg...
your saying i should buy at least 550cc injectors even if i want only 10psi to make 250whp?
and then the tuning can lower the fuel injection rate depending on my boost etc...
and when i up the boost, i get it re-tuned and speed up the fuel injection rate?

correct?
