my RB20 problems all sorted out

[JonPowell]

10 digit number is the part number

[blk90s13]

hmm so i guess i have a z mafs on my rb then its the same number

its not the mafs then cuz i already tried the Z32 mafs i got and it didnt change any thing

[Yellow4g63]

That 1st pic yes it should be pluged. unless you have a boost gauge then you can use that.

[vududoc]

the top 2 pics you posted:1st = boost gauge vacuum2nd = PCV4th= Speedothe other plugs connect to fuse box in bay.

[blk90s13]

and i need them all plugs right ?

there is a metal box ( looks like a transistor ) do i have to get that plug too ?

[vududoc]

that metal box is a dropping resistor...and yes you need that too.

[blk90s13]

ok i plugged that in and changed my fuel pump from a walbro to a jdm fairlady pump ( way too loud )

anyway i started the car it ran good at like 1500 rpm for about 30-40 seconds then shut off on its own now

i am thinking its fuel problem ? it was running very rough with the walbro at about 500 rpm then shut off

[JonPowell]

The Walbro is probably flooding it, the pump flows way too much volume...it is overrunning your stock pressure regulator....use the walbro, but get a new adjustable regulator

[blk90s13]

yeah that was the next step

i ordered a fuel pressure gauge from summit will install it this weekend and see wus up

42 should be the fuel pressure right ?

can it be done while car not running with ke in the ON position onle ?

[Yellow4g63]

I can't rem maybe I already asked but is the fuel filter new? or is your old KA one?

[blk90s13]

i have a Z filter that i had on my sr for about 3 month but i bought a new one along with brand new lines to start all over again

next thing i am changing my fuel hard lines it self

this thing is driving me insane right now

anyone in NJ willing to come give me a hand please i pretty much know it all but i just kind ran out ideas here

[blk90s13]

so no one in NJ willing to help out with some ideas ?

[JonPowell]

If you could somehow get it closer, I would love to help...you know I would!

[blk90s13]

i think my next option is bring it over to u and yes i know jon u would help deff

i was looking into the SR wiring cuz i had a SR in my car and the swap was done by someone other than my self so there is a black/yellow wire on the grey plug near the battery that is used on the SR swap its the idle air control where /wut color is it on the rb harness cuz its not hooked on my grey plug

also where is the idle adjust screw pm the throttle body i cant see it any where

[JonPowell]

The idle air controller is run through the RB upper harness....should be completely self contained.

Leave the idle adjust screw alone, it is a ***** to reset it nice nice.

[vududoc]

37 psi w vac 43 w/o vac

[blk90s13]

i think i am sell my car i am so sick of it wont run right

powell u free to look at it some time soon ?

i may trail it up to u in the next week or so and leave it there till its running

[JonPowell]

Come on up, I would love to get it running for you.

It looks like I may have something going on this weekend, but next weekend, the 19th is good for me...call me when you know your schedule for sure and we will get you handled.
