hey everyone i just bolted on a turbo kit on my gsr, and i heard that since i changed my injectors to 750cc injectors and installed a 255 walbro fuel pump that the car wont start because i have a stock ecu. i havent tried start the car yet but i just wanted to ask people before i f something up.

 

it wont start, you will flood the engine with gas

you can however put in stock injectors and start the car

 

Don't do it. Get a ECU with a basemap for your setup, start it and make sure it idles fine and doesn't over heat. Then drive straight to the tuner.

 

can i drive it with stock injectors if i baby it until i get it tuned? and will the fuel pump be a problem?

 

you can drive it on stock ecu and stock injectors as long as you don't go into boost

just remove the charge pipe from the intake

fixed

 

true and false


the car will not start with stock ecu and bigger injectors

you can run it on stock injectors and stock ecu, but do no beat on it

you dont need to undo the charge pipes or anything as long as you stay out of boost you will be perfectly fine

do not drive around with the charge pipes undone as it can overspin the turbo

 

I used to think that as well, but TheShodan said, its a myth...
Hopefully he will chime in

 

you guys say "stay out of boost" how will i know when im in boost? is there a certain rpm to keep it under or what?

 

Do you have a boost gauge? If it reads 1psi. That's means you're in boost

 

no i need to get a boost gauge. just trying to find out whats the different between a mechanical boost gauge and a electrical boost gauge, and why is the electrical boost gauge 200 bux and the mechanical boost gauge is 60 bux????

 

??

 

mechanical will work with a vaccum hose and electronic should read off the map wiring

 

since you dotn have any idea of boost...

dont floor the gas at all....not even from a dead stop 1k-2k range. dont even go half way with the pedal.

dont go above 3500 rpms.

as for the gauges.. mechanical is quicker reading, electrical is a tad bit slower in response.

 

Just stay at partial throttle and dont floor it. In other words, "baby it".

Going wide open throttle will cause the turbo to spool up at a certain RPM, depending on what turbo you have. Its very tempting, but you can do it. ;-)
