Stock injector size???

[perley03]

Alright, again i searched but came up with nothing. I have a 90 gst and was doing some fuel calculations the other night and had to come up with stock injector size.....there are no numbers on the injectors so even Mitsubishi couldnt help me. Anyone know what the stock size is on a 90???

If it is a M/T they are 450CC's and if its a A/T then they are 350CC's

1g n/t is 240cc,1g turbo auto is 390cc,and 1g turbo 5 spd is 450cc as are 2g turbos.

im pretty sure its the 450's

 

[hottboost]

Yes that is exactly right. Sorry!! Had a brain fart.

sweet! thanks guys for the quick reply

what size are 2g auto injectors? are they whight/tan?

 

[morelock]

2g m/t and a/t turbos are 450s.

 

[red1993gsallmt]

2g m/t and a/t turbos are 450s.

a buddy of mine had white/ or light gray top injectors in a 2g he bought, the bottom was a little longer then my 1g 450cc injectors, just like the black top ones are.. the car was stumbuling on boost until he changed the injectors. ill try to get a pic of them. it seemed like they were to small

Yes, this is absolutely right. The only thing I would add to it is that the 2g 450 turbo injectors are the black top ones and they will say INP-018 on one side and MDL450 on the other. They also feature a dual spray pintel cap that aims the fuel at the valves while the 1G 450 bluetop injector's have a single spray pattern.

I sure didn't know that about the spray pattern, I guess I learned something today

Mitsubishi Injectors are color coded so if they are Mitsubishi Injectors this list should help:
pink - 240cc - (1g 2.0Ln/t)
tan - 390cc - (1g turbo auto)
blue - 450cc - (1g turbo m/t, Galant VR4)
black - 450cc - (2g turbo)
yellow - 510cc - (evo 1-3)
pink - 560cc - (evo 7-9)

And here's a way to identify them based on the casting numbers:

The corresponding numbers should be on the injector.

Non-Turbo 1.8L - N210H Injectors-casting #INP-057 (210cc High Impedance)
Non-Turbo 4G63 - N240H Injectors-casting #INP-059 (240cc High Impedance)
Turbo 4G63 A/T - B390L Injectors-casting #INP-008 (390cc Low Impedance)
Turbo 4G63 M/T - B450L Injectors-casting #INP-009 (450cc Low Impedance)
2G Turbo BlackTops -MDL450 casting #IPN-081 (450cc Low Impedance)
2.4 - MDH275-casting #IPN-065 (275cc High Impedance)
JDM motors that came with the B16G had yellow 510cc injectors

The two motors besides the different turbo and injectors are identical except for the cams. Someome correct me If I am wrong on this.
