Exhaust manifold flange - EVO1-3 same as E4+?

[ENGINR]

As per above - are the exhaust manifold flanges (and gaskets!) the same across all the EVOs?

 

[BYBY5L]

Pretty sure they are,
I can check in about 15

 

[ENGINR]

Ace

 

[BYBY5L]

Yep, the same, had to check cos I couldn't remember whether it was intake or exhaust that was same

 

[evo-gsr]

I can confirm the gaskets are 100%

 

[ENGINR]

So exhaust is the same, intake is different.

I think intake might be the same too. Was old mate on here with a late evo intake and he unbolted plenum and spun it around to suit our setup

 

[BYBY5L]

Yeah man, exhaust same,
intake I'll check shortly, have a 5 plenum so cant be sure on 7-9 but I'm sure 4-9 are the same, will check soon though

1-9 exhaust head flange is the same. 1-3 inlet the same and 4-9 inlet the same will not fit vice versa.

 

[ENGINR]

Ace, I just needed to make sure the exhaust manifold flanges are the same. Thanks fellas.

 

[BYBY5L]

Yeah as caged said Shane,
Were you talking about Jayrome's setup there Jack?

 

[4piknup]

Na not jeyrome. Someone else. The plenum could split with bolts off from the trumpet base plate. It had maybe 10 bolts and they said they just flipped the plenum to fit our engines.
jamo commented it was a really nice manifold.
(Maybe hypertune?)

 

[4piknup]

Nup not hypertune

 

[ENGINR]

I think that was Todd (runuts).

VR4-Evo9 same exhaust mani flange for custom work (VR4 needs some slight trimming near power steering mount)
Vr4 have all M8 studs
Evo1-3 (unsure)
Evo4-9 Have 2xM10 outer studs and the rest are M8

Intake manifolds have the same stud pattern:
Vr4 big port
Evo1-3 small port
Evo4-9 is mirror image of the evo1-3 small port plus injector holders (bosses what ever you call them)...

Evo4-6 mani has less vac ports over the Evo7-9
Evo7 mani has MAP sensor active (evo8-9 have the holder but no hole)

You can mix and match all the above with a little bit of welding......

If making custom exhaust manifold, use min 12mm flange plate material..

EVO1-3 have two outer M10 studs.
