if i turbod the b18b at the stock internals using safc and 450 injectors what will be the maximume hp ?

 

not much, get better ems, chipped ecu crome ect if you want to make max power.


with a better ems setup 300 would be easily reach

 

well 450s and stock fuel pressure are good for about 300 whp, so is a stock motor give or take.

i wouldnt run much boost you arent gonna be pulling timing

 

what if i use a walpro 255 ?

and what is ems ?

 

larger pumps will only help power if more air is added with the fuel to make more power.

otherwise given X ammount of low boost you should be fine with a oem fuel pump

but you might end up wanting more boost cos technically i could see 10-15psi on a b18 block with a good tune and good supporting fuel and ems

 

so the safc tuning with 450 injectors with t3/to4 , walpro 255 what will be the power i can take ?

 

well the safc for tuning isnt that great, a ecu thats chipped for crome would be a better choice.

your setup could be capable of 300hp however tuning is the key point in making power on any turbo motor, better tuning will yeild you better results and the way you tune is have a good ems to tune on.

they way you sit right now probably 250 but i wouldnt trust the safc hack deal

 

ok i get it now thanks alot. i have a small question

i know that the ignition timming is so important to the turbo system . does my stock ecu can control the ignition timing with the turbo ? and does my safc control in the ignition timing or it just tuning the a/r/fuel ?

 

just af fuel ratios not ignition timing

thats why with a chipped ecu you can change and correct any needed air/fuel/timing/ignition ect.

with safc you are very limited to now days chipped ecu's

they arent that much money either just get the ecu have it chipped then get it tuned and you are set to run whatever psi ect

 

thanks alot for you hosbitality. and thanks for helping.
