ok i have a stock d16y7. im about to run a t25 at about 8psi. i have a bigger fuel pump that im going to install and big 450cc injectors. will my car idle or even run. before i even tune it with uberdata or chrome??? i want to install everything and then go to a shop to go get it tuned. but if it wont idle or run i dont want to install all of this.

If it idles, it will idle like holy hell. Those injectors are near twice as big. It won't run right that is for sure.

 

i doubt it. 450's are almost twice as large as stock so your gonna be getting almost twice the fuel. best bet it to get a basemap for the 450's so you can go to the tuner. or leave the stock injectors and ecu in, CAREFULLY drive to the tuner, install your fuel components and then tune.

 

it might start, but chances are it will eventually just die. Id say driveability will be next to none, if it even starts.

for example, on my old all motor setup on my ITR, I went from stock injectors to 440s, it would barely idle, and as soon as I touched the gas pedal, it would just die.

 

ok how does this sound. keep stock injectors with bigger fuel pump, run boost at like 5psi. when i go to the tuner, install the 450cc's and then tune and run at 8psi

 

Stock injectors are at right at 100% duty cycle NA.

At 5psi, it is probably going to just come apart from lack of fuel. The option put out before of baby it to the tuner never crossing into boost and install the injectors their was your best option unless he can basemap it before you bring it there. Stock injectors is not going to have good results man.

psi isnt the problem. its idling..

 

Keep the stock ECU and injectors in, pull off a silocone coupler to create a boost leak, drive to the tuner, install the injectors/fix boost leak/put in ECU, and get it tuned.

IF your car starts, it will idle horribly, and then probably stall out.

Or you can just try to avoid spool through every gear.

 

keep in mind boosting on an untuned setup is like banging clubfly's without a condom

 

Believe me....with bigger injectors and no tune it will idle VERY VERY rough.

When I got everything installed.....I had to get my car towed to the dyno shop to get tuned.

put everything on but the injectors, create a boost leak ie unhook a coupler, and then just drive to the tuner on stock injectors
