7G DOHC headswap.... The easy way! ???

[da1085]

does this mean it doesn't fit?.....damn......i hope it works with a 97 dist.....

[seth98esT]

Kevin tried teh 94-95 Dist, this fast guy had a 97. Not sure on the differences between the two.

[bronxbombr]

well figure it out and post the TuT!

PICTURES!

[phizz2k]

Hmm although I'am all for this project, I have a hard time unerstanding this working. I would like to see some pics from fastmgalant's build but how long is that gona take

I took apic from a 1g eclipse cas and compared it to a pic of a 96-98 distributor on ebay... I can understand what 4-G-Rim was sayin about the 4g64 distrubitor being to wide through these pics. It also looks as if it is too long as well, but that just may be me.

Well here are the photos... What do you guys think

4g64 96-98 sohc distributor


4g63 1g cas


Regardles, I will check out a local junkyard 2morrow morning and see if I can get any 7g distributor to fit into a 4g63 dohc....

if its just that its too long,
just remove the studs and get some longer bolts.
it will stick out a tad, but the o ring will still seal.

[4-G-rim]

Well...not only is it too long, the diameter of the 7g distributor is too wide to even slide into the DOHC head. Compare the pic of the CAS sensor compared to the part of the 7g distributor that suppose to slide into the cylinder head.

Like I said..I wish I had a digital camera to show pics of what I am trying to describe. :-(

[Blue Ice]

well i have some time this week, a 1g dohc head, a 94 distributor, and a good camera phone. and i will post pics... it just might be end of the week

harr harr

[da1085]

sweet!.....if this works i'll have another project.....of by the way it kinda sux working at autozone's parking lot....changing a starter without having any tools sux specialy if you've been drivin around for like 3 hours....but with that aside, i hope we can find out the answer on this question....."7G DOHC head swap.....The easy way! ???" :)

[4-G-rim]

Alright..I am going to take pics tonight and post what I am explaing about the issue of the distributor not fitting into the DOHC head.

[seth98esT]

I thought I posted, I think it got deleted, along with Peanos last post!

Who ever "tests" this theory needs to use a 96-98 Dist as the 94-95 has already been tested to no avail. Doesnt matter if its a 1g head or a 2g as they both have the ports there for the CAS, just the 2g doesnt use one stock.

[4-G-rim]

I am going to test the distributor from -G-rim today on the 1g DOHC head to see if the 96-98 distributors fit. Though I am a bit confused right now though. This would mean 94-95 4G64 SOHC heads were different from the 96-98 4G63 SOHC heads IF the 96-98 distributor fits into the 4G63 head and not the 94-95 distributors.

Get what I am saying? :???:

[seth98esT]

Yes, but I woudlnt put it past Mitsu, they change little things like that all the time. I am pretty skeptical at this point that it will fit. I think Mr Fast pulled a Fast one on us!

if it didn't fit,
i garuntee it would hardly be impossible to make an adaptor.
i wish i would have tried this while i still had that parts car.

[seth98esT]

I will go to the yard tomorrow and try a 97/98 Dist on a 1g head.

Pansies!

Idk, I got nothing...

96-98 should be the same distributors. Like I said...I am going to see how the 96 distributor from -G-rim fits on the DOHC head.

I have already started trying to figure how I can. ;)

Though...i should really step up and do more packing. My significant other has done a bit more packing than me :-|

ugh i am getting very impatient with that guy, still waiting on those pics, and the talon tsi head still waits for me at the junk yard, dude please post pics...

I think he's just pulling our chain, I know if I did this, I would be bragging with pics.

definalty or he might have done it just something went wrong i dunno, i guess we just need to wait or do this without waiting on him

[4-G-rim]

I haven't gotten a chance to take pics or test fit the distributor from -G-rim to the DOHC head since yesterday was raining pretty much ALL night. Sooo...I found some pics of the 4G64 motor in my 7g and the 4G63 motor in my Galant VR4 to show you the differences.

SOHC 4G64 cylinder head
If you look at the pic...I circled the big difference between the DOHC head and the SOHC head. The SOHC has a "sleeve" that kinda pertrudes out. The distributor "shaft" slides into this sleeve to where the rotor in the end of the shaft slides into the slot on the camshaft.


DOHC 4G63 cylinder head
Now where the CAS (Cam Angle Sensor) is on the DOHC head...there is no "sleeve". Without this sleeve..there is no way the distributor will fit into the DOHC head since the distributor shaft is about a inch in length. Also not the mention the diameter of the distributor shaft exceeds the diameter of the hole of the DOHC head where the CAS would bolt on to.


Now from visual inspection...I don't see any difference between the SOHC cylinder heads of a 1996 (from -G-rim) and the 1995 cylinder head (from my old 95 Galant), they look identical. Like I said....there is a difference between the my 95 distributor and the 96 distributor, which is the cap and rotor. Their shafts though are idenitical from visual inspection.


So right now...I don't know how FastGalant got the distributor to fit into the DOHC head.
