550 injector / lexus info needed
 

Okay so i just did the top end on my car and installed 550cc injectors with a aeromotive adjustable fuel pressure regulator and a lexus afm with adjustable set screw and also an air fuel ratio gauge first i was wondering if anyone knew what color the wire off the o2 sensor was that i need to use for the air fuel gauge and i was also wondering what i should set my fuel pressure to now that i have these bigger injectors and if anyone knows about were to set the afm to that would also be nice 1987 toyota supra turbo

o2 wire to tap is the blue wire
screw the adjust screw in all the way to start
go with best guess on the fuel pressure starting on the lower side

i just did the same thing but i didnt use a fuel pressure regulator and ive been driving it for 2 months nothing bad has happened so run what ever the stock pressure is. the point of the 550cc and the lexus afm is to equal everything out so you dont have to adjust everything.

yeah i was told by reg that the fuek pressure upgrade really isn't necessary



so night-rider where did you get the adjusting screw ?

i bought the air flow meter housing off of suprasport.com and it comes with an adjustable screw already

quick question. im confused with the lexus.do we need to buy just one or 6 all together. ive seen pictures of groups of 3 or 6, but ive found 1 by itself relitivly cheap. i feel like only 1 is needed, but i dont know much of the fuel system. i jsut dont want to buy not enough or too much.

Que freakin what ?
are u talking injectors ?
lexus makes the air flow meter you need one

many places make the injectors you need 6

let me clarify my confusion, sorry i was short on sleep(3rd shift)i knwo that the supra has 6 injectors. but i just need 1 lexas afm, corrcet? ive been lookin at ebay and i see sales but i see ones by themselves and others in groups of three ( still talking about afms) to me, i see it as i only need one

yes all you need is one and the ones on ebay only sell one and some have pics of a group of them but still only have one up for auction.
