4G63 EVO Intake

straightarrow · Post by **straightarrow** » Wed Feb 18, 2009 12:29 am

I saw a '03-'06 EVO 8 9 intake on ebay that also said 4G63 in the title. Will this fit on my first gen 4G63 head and can I use my thottle body? It looks as though it's facing the right way for my Arrow swap. Thanx, Brent

No it wont. The flange to bolt to the head is wrong. But I believe you can modify it to suite.

You can always get a JM Fabrications inlet manifold, as they make them facing both ways.

If they are aftermarket, you can always ask them to reverse it, they usually do it at no extra cost.

You could reflange the Evo manifold to a 2G (small port) flange without too much drama. It would still involve welding aluminum, but that's not that hard to have someone do. If you use it with a 2G head, I don't see there being any problems.

but doesn't it have egr bs that needs to be dealt with?

Thanx, I guess I'll try and see how much JM wants for an intake. Otherwise, If you see a swap intake, I'm looking. Welding and machine shops I've talked to around here give me an "I'll do it" answer but an "I don't know about that look". Oklahoma, go figure.

hit up bill to switch the flange for you...he's working on mine and has done a few other members too.

JM Fabrications can reverse the throttle body position at no extra charge. They are a good option.

This is for cali,
I wanted to build an EGr capable intake manifold that looked OEM to the smog inspector. first I needed a little wider material so I used a 1/2 plate and marked out the sencond gen and the EVO flange patterns

then I routed the flange to transfer the exhaust gas from one side of the head to the other

then I cut the flange from the EVO manifold

then i covered the eGR passage

and then re attached the EVO intake to a custom flange

the OEM working EGR valve will be put right in its original place for the EVO set up, if you dont desire to use the EGR passage, just change the intake gasket to block it off

i will be cleaning it up and testing it out before I send it out

that looks awesome bill! im sure the smog ref over here wont even notice the change.

let me know when you got the housing done too so you can ship both of them together; no point in paying for shipping twice.

how about welding a 1g intake manifold flange to an evo mani

Bill Hincher · Post by **Bill Hincher** » Mon Mar 08, 2010 6:33 am

the inlet ports on the first gen intakes are twice as large as the EVO and second gen 4g63

the best of both worlds would be an EVO intake with the first gen intake ports

new intake work

I needed a way to grip the intake to plane the manifold correctly

Was there something wrong with my idea to just flip the stock intake manifold upside down? You could just use your same idea of routing the EGR port. I would think most of use use 1G heads and intake manifolds due to the huge abundance from all the DOHC engines Mitsu made. I think the EVO route might be a lot of work for a a less obtainable piece.

hey Jeff >;o) how ya doin man >;o)

I built the jig so I could plane the flange on the manifold, its for somebody else, there ant nothin wrong with your idea

where are you on the car?
