    just imagine,
    a 3.5l(diamante motor) DOHC stroker in a 8g....
    mmmmm
    talk about a powerband.

    well, the internals fit in the V6... i'm sure the head could be swapped somehow... maybe i could work on this when i move back to PA in the spring and actually have a garage to work in...

    I am kicking myself in the butt for not thinking of this and doing this at the time I turbo'ed the car.

    BTW: You used a 4G63 timing belt right and the 4G64 spark wires right?

    i'm pretty sure the 63 timing belt doesn't fit on the 64DOHC due to the extra deck height. this is a problem with guys building the 7bolt 2.4 vs the 7bolt 2.0

    From my knowledte, you use a 4g64 DOHC timing belt and cam gears(for the timing marks).

    i know you can swap the cam gears over, but you need to remark the tdc mark on them, i believe it's 1.5 teeth off?

    so if a guy were to go out and get a dohc head, which oil galleys would they need to plug before putting the head on.

    yes its an upgrade,
    but still,
    if i were you i woudl continue along your same path,
    although this mod is a fairly simple and painless way to get a significantly higher power out of your 4g64,
    there is still no substitute for a knock sensor, distributorless ignition, and a turbo or galant gs ecu.

    you can still boost this setup, but the mechanical and tuning limits are the same as with the 7g sohc, however you of course will make more pwoer across a greater powerband with this setup, turbo or no.

    by all means, if you desire, go ahead and boost yoru motor with the dohc head.

    but i mean,
    you are already so close to the 4g63t setup, why cut yourself short at this point,
    all you need is a little wiring.



    but to everyone else,
    if you seriously want to add some power and capability to yoru engine,
    do this mod.
    just think about the new levels of power you can run....
    now that you ahve a 4g63 head,
    you can get cams, valves, valvesprings, camgears, different intake manifold options...
    all for the 1g or 2g eclipse turbo!
    that means you can get used parts fopr CHEAP off ebay or tuners and increase your power.

    i imagine this setup with some cams and a good tune could get you into the 13's without a lot of hassle, or any boost.

    those of you that are more willing to drop the dime... could see 12's!

    Ok...today I did some packing up getting ready to move into my house. Well I finally found my distributer from my 95 Galant. I went ahead to fit things to my spare 1g 4G63 DOHC cylinder head:

    The 7g distributor doesn't fit. :-? I compared the 1g CAS to the 4G64 SOHC distributor there is a big difference.
    First off the distributor shaft where on a SOHC 4G64 head it would just slide into the cylinder head and the rotor slot wouldn't fit into the end of the camshaft. Well the 7g distributor shaft is too wide to even fit into the 63 DOHC head. So basically...the rotor slot won't reach the end of the intake camshaft and no way it would seal or even bolt it to the head.

    Basically it won't fit...or at least I can't get it to fit, I don't see how. I don't know if its just the 94-95 distributor are different from 96-98, but I don't think that would make a difference.

    Fast...please post pics on what you did to make the distributor fit into the DOHC head, because I don't see how you did it. I wish I had a digital camera to show what I am talking about

    Well..yes, I should of clarified myself. I know the actual rotor and cap are different from the 94-95 vs 96-98 distributors. What I was referring to was the shaft that goes into the cylinder head.
