Injector ID - HELP!!

[boost infested]

ok, i am buying a set of 540s from a private sale. He said he got 6 of these 540s from a supra. (i dont think supras have side feeds)

numbers on the injectors:

red top - side feec5A1223250-74150

23250-74150 is the part number but where or how do i go about finding the actual size of these injectors? He also said that they are HKS made by denso.

can someone clearify this?

thankyou.

send them off to RC engineering to get cleaned. they will balance them and give you a print out of before and after results. you should do this anyway using used injectors

[daniel240]

whats their website and how much do they charge to do that?

it came out to about $120 after shipping. for any used injectors i would do this. i couple of my 480's went to RC at 460cc and came back at 478cc

i saw and compared them with my ka injectors. Both of the o-rings are spaced the same but the girth of the top ring is bigger on the ka. so no go.

couldnt put the ka o-ring on the new injector? or jsut fine a bigger o-ring? ims ure you could make it work.

there are still a few guys around the boards selling 550cc injectors. just ask around and you will find some drop-in's
