i just put on a custom turbo kit on my 99 si and i was wondering is it necessary to have injectors and a fuel rail. with stock ecu?

 

injectors yes, fuel rail no

 

You don't need a fuel rail unless you start pushing around 1000+ hp. Get rid of the stock ECU and get yourself an AEM EMS or something similar with injectors matching your desired HP goal.

 

if i were to keep my ecu stock for the time being cuz im low on cash, would i need to change my injectors? btw this is a daily drive car so its not goin to be seeing much track time. or much boost in that matter.

 

bumb.

 

if you dont have money for a any kind of fuel management, i wouldnt recommend running ANY kind of turbo. You will blow your **** faster than it took you to put it on. Fuel managment in the KEY to turboing a honda.

 

i have a fmu on there i was askin about injectors.

 

you dont need to upgrade the fuel rail


if your runnin the FMU, you better have an inline fuel pump, not an in-tank, but an upgraded inline, the intank cant keep up with the needed pressures of an FMU.

injectors and hondata./ aem EMS is the preferred route,

you cannot run upgraded injectors without a means of tuning them or trimming fuel such as fuel controller or hondata, ur car will just run super rich and not be able to idle. or drive properly.

 

i have an intank walbro 255..isnt good enough?

 

u do not want to put bigger injectors in without tuning. my recomendation would be (because i know your dieing to boost) put the turbo kit on and run stock injectors just keep the boost very very low. dont install the new injectors until you get a decent ems. hondata is a cheaper route than aem and uberdata is even cheaper
