God only knows how long they had been sitting in that old twin turbo block!

I had "cleaned" them with break fluid cleaner when I installed them in the rails. The passenger side rails were filled with white gunk, since they had filled with water at the junkyard. Seemed to clean up fine....

Swapped out the fuel rails with just a few curse words, mainly due to dropped parts. Turned the key on and let the fuel pressure build and turned the key.


Purrrrrrrrrrrr.

WTF!?!?!

It runs and drives perfect?

At this stage it doesnt make sense as I am now running injectors rated 163% larger than ecu is designed for! The only explanation I could have for now is that the intake from the MAF isnt tight as I damaged the T-Bolt and need a new one. So if I am sucking in air, just a tad, that isnt being read by the MAF, and it balances out the larger fuel flow.

Either that or they arent 440 cc injectors.

More info tommorrow.

What engine were they from? There's like three different gray injectors, 340, 360, and 380 IIRC. If I find the site again I'll post the part numbers.

Twin turbo 2.0 JDM. thats all I know. For whatever reason I do not remember where I read they were 440 cc?

The heads on the block were shim and hydraulic lifters.

Hydraulic = H and G only. And H was the Twin. H's came with 380cc's.

Yellows are 444cc or something.

FUck.

So how did those twins make 270 chp on 380 cc injectors?

doing some of the cc/division = max hp, 380 cc injectors are good for 308 hp.....

I guess I will invest in upgrading my rrfpr to a 3-1 ratio. Cheap safety....

Hey, I was wrong with the cc's. Dunno what I was remembering.

(This site has so much damn info, crazy stuff too, like an cut up RS-RA engine)

430, 444 and 480. Yellows are 480.

Also, H's only went to 260PS about 256hp with the shim over bucket. HLA was 250PS about 246hp. So I'd guess you have the 430cc injectors.

Mine are grey top.

So I am going to give them a 380-430cc maybe I don't know rating!

there are numbers on the injectors themselves. I guess I will pull one out and google it.

That's some interesting shiz right there.

I just had my Grey Tops flowed.
@ about 40psi they flowed about 420cc/min

I will post numbers off the rails later.

i looked at my injectors the other day and they are a light pink colour. is this normal?

Yes, the stock turbo legacy injectors are pink in color.

I am very very happy with my injectors right now. By adding a little fuel, I am at 11.2 -1 AFR on the dyno up to 6500 rpm

what is the stock size cc's for the pink turbo injectors? thanks

what are advanages of larger injectors. what else is needed to increase hp? as cheap as possible!

Stock NA is 270
Stock Turbo is 370
Cheap Nismo 370 are $75-150 and fit in NA rails, cant remember which, but I did it.
$? 430-440 cc fit in NA rails as well.

as a stand alone swap what difference will I get by going to a larger injector? thanks for quick reply vincent. safe driving, love my subaru's past and persent. D

Rich A/F and less fuel economy

thanks, wondered what would happen. when money gets better, would like to install a larger turbo. not killer larger as I still pay for my gas like most of us. yet 200-215 h.p. is about what I would like to run. thanks for your reply and time. be well and safe driving. D

THAWA cool page i wish i could read japanese, i got the yellow 480cc injectors off my ej20k vf22 motor.

post sompe pics with these rails and injectors in n/a rails guys

270 cc on the left, 440 cc on the right.

so the one on the left is a n/a 2.2l ej22 subaru, and the other is from japan?

correct.

Your 550 injectors looked like this didnt they?

no no they look like 2.5l ej25 suabru n/a motor injectors.

those ones you posted are like the japanase ej20k injectors i got with my motor.

thanks douglas vincent now i now i can use them on my sohc ej22t motor direct bolt on.
