i bought a modded evo a month ago and was wondering if my injectors are stock? there not labeled at all im sure there most likely not my current mods are:
hks 272 cams
hks cam gears
arp head studs
dyno flash tune
walbro 255
intake
hallman boost controller
greddy type s bov (in recul.)
ets upper intercooler pipes

there other mods but that basically everything i could remember off the top of my head. Do any of you guys know what brand/cc these are? thanks in advanced

 

those don't look to be stockers. I think they most closely resemble precision injectors. look up the oem online and then look at precisions. google - oem evo 8 injectors then open images. you'll see what I'm talking about

 

Subscribed. My injectors look exactly like yours. I was under the assumption they were stock, but it would be nice to find out they are bigger.

 

Why not pull them out and send them in to RC Engineering to have them flowed so as to find out what size injectors they are?

 

Yea, Sparky is all over it as usual. taking them out and having them flowed is going to be the best way to check.

 

can you pull the Rom and see what they are scaled to? it wont say what exact size they are but it should help in finding out

 

so i talked to the previous owner and he said they were 680cc's but no sure what brand

 

That was easy.

 

Hi, just wonder is there a way to tell a weak fuel pump and fpr???

 

still looks like Precision Injectors to me.



yeah you can go to autozone or advanced and they should have an inline fuel pressure tester. you "T" it into the line at the manifold and fuel pressure regulator to test the pressure. Now I don't know what it should read though. Maybe someone else can chime in.

 

They look like PTE's

 

my delphi 1000cc looked exactly like that.
It's a rochester type injector.

Only way to find out flow rates/size is either part numbers or flow testing

 

x2 on the delphi i think your right i just searched and they look exactly the same
