i have a d16z6 with a a 14b turbo full msd ignition

dsm 450 cc injectors tuned on chrome pro at 9 lbs

now i heard that your stock fuel pump can handle up to 200 whp

im having problems with hesitation on the top end,

normally the car runs strong, pulls strong,i but sometimes (about once every couple weeks) the car will start to hesitate and or feel slower in the top end as if the car is starving of fuel, and when i shut my car off the car wont start and i have to pull out the back seat and bang on the fuel pump,

ive changed the fuel pump with a friends and still does the same thing

any help is appreciated

 

its possible, just get a walbro 255, u cant go wrong for a 100bucks.

 

ive got a d16z6 with a 14b @ 11lbs with 450cc injectors and I had to upgrade my pump to a walbro 255, its only 100 bucks man

 

you said you had to upgrade?? were you having the same problem as me??

also if i change the pump will it have to be tuned knowing it has a bigger pump??

 

It should be re-tuned yes and if your running a larger injector, then you always need to upgraded your pump!
