Anyone know if a evo 4 fuel rail will fit our cars? If not who makes one that will accept a center fitting? Also both ends accept fittings. Similar to this:

the same fuel rail that will fit any eclipse turbo!
we have the same engine! exact same!
Why are you changing the fuel rail anyway? they flow enough pump gas for 500 horse. and enough race gas or e85 for over 400

no need to change rail ,you can polish the stock one ,I even tapped mine for a fuel pressure guage.The 1g/vr4 is the best rail


save your money for something that needs upgrading

Umm, that was the model year they went to a "rotated" engine/transaxle. Do the EVO8 fuel rails bolt in with that configuration? Might be a better comparison.
Not sure if the mounting bosses will line up but maybe one of the UK guys will chime in...

Evo 1-3 has the same mounting holes but the flanges are rotated a bit but should work.

Yeah i had a feeling 1~3 would be fine, but 4 wasn't to sure.

The injector spacings (along the rail) should be similar.
If you align it so the 2 bolts that fix it to the manifold/head you'd only have to worry about the fuel line fitting and the FPR fitting being the correct diameter. And if the diameter of the rail is the same at each end, and both fittings are the same dia as the rail....

That being said, the VR4 fittings have a smaller dia to the Evo 1-3 fittings and most likely the Evo 4+ fittings too. Can't see why the Evo 4 fuel rail, lines and fittings wouldn't be too far off from fitting, just have to put the fuel feed and fuel pressure reg on opposite ends from the factory evo 4.

Evo 4-8 manifolds have two mounting bosses for the rail to the intake manifold. Galant and Evo 1-3 have three.

The Evo 1-3 is a confirmed fit on the Galant head. I had that last year.

4-9 is a no go without mods at least. (or if the outer two holes are in alignment and you skip the middle mounting hole.)

uh yea 1990-1999 Mitsubishi Eclipse, 1990-1999 eagle talon, 1990-1994 plymouth lazer, 1991-1992 US galant vr-4 all have the engine mounted on the left side of the car. that is THE SAME ENGINE! SAME ORENTATION! most of all parts are interchangable.
Now the EVO 1-3 have the same orientation, and same engine execpt for differences in turbos and injectors.
OK so in the EVO 4 mitsu decided to address the weak transmission issues and when they did they found that it no longer fit right so they rotated the engine to the right side.
this is where parts dont fit anymore. EVO 4-9 and 10 are not interchangable.
EVO 1-3 is basically the same car as the VR-4.

Dude did you read this correctly?
Where are the turbo and intake manifolds located on the USDM cars? Now rotate that engine 180 degrees. Where does that put the manifolds? The EVO4-9 would place the turbo in the rear, wait a minute the turbo is on the front?!? That would mean the head casting is DIFFERENT on the EVO4 ( which is what the fuel rail fitment is on the first post ).
SO if the rail bosses were to mount up ( on the DIFFERENT head castings ) it's a go.
Weaker tranny or torque steer? The current configuration makes the driveshafts equal-length ( which helps reduce TS ).
Sorry off topic for the OP. If the outer bosses are the same spread as the USDM rail plus centric to the injector ports it's a match...

mitsu reversed the air flow across the head.
reread this.
I tell you that the Evo 4 and up is DIFFERENT. Parts are not interchangable.
EVO 1-3 are interchangable.
I've rebuilt all versions of the 4G and I know what works.
Evo 4 and up dont cross over.
Reread my post.
Why waste your time trying to mod a fuel rail that doesn't fit to fit when you won't even see and difference in power and you can just buy an aeromotive rail or any other rail that fits the eclipse, talon, lazer, or vr-4?

Translated =
You might like to purchase a fuel rail from any turbo-charged Eclipse as they use the same basic engine as you have in your vehicle now.

A more concise answer may have been easier to understand. /ubbthreads/images/graemlins/wink.gif

Ok the sard unit probably won't work for what i'm trying to do, but the hks evo 2~3 unit will. Can any of you nz or aussie guys confirm that the hks unit has a center outlet like the one pictured below? hks # 1407-RM003. Pictured is a supra rail.
