I have a STOCK DX fuel pump on my 97 jdm b18c(r) in my coupe. My setup is going to be (in 1dy)

J's Style Racing Intake
98 JDM Type R Header
Carsound Cat
Skunk2 Cam Gears
Apexi VAFC
B&M FPR

I'am going to tune the car and my question is should I get a Walbro255 fuel pump? or is my DX one doing its job?

 

stock is fine. the 255 wont work properly with a b&m, plus, its overkill. replace the stock one at 220+ whp.

 

Q- So is the DX fuel pump killing my performance? or no, would it w/ tune

Q-What if I get the smaller walbro 190?225?

Need quik answer

i had a stock cx feul pump on my turbo set up with no adjustable regulator and 440cc injectors on 10 psi running 12's so i think will be ok

 

isnt a B-series VTEC pump different from a SOHC No-TEC pump.. i could have swore they were.. educate me.

im pretty sure that they are, im just saying that i got by without one on my set up for a while with a shitty pump

 

did you have a drop in fuel pressure in VTEC? run lean?

 

not to my knowledge im mean i never had any problems with it

 

I believe SOHC cam vtec sand non vtec b series use a 79lph pump stock, while B seties vtecs use 135lph pumps stock, you have spent the money on a type r swap, might as well get the correct fuel pump for your motor. just get a stock pump for a gsr for your year car, it should bolt right in. cheap insurance
