Not sure what engine i have

[blackhawkgsx]

I have a 2g gst i know the 7bolt started in late 92..... but after buying my 2g i have done some investigation and found that i have a 6 bolt my question is..IS there a difference between the 4g63 and 4g64 cam gears because I have them on my engine ..... also have a 2g intake mani ,1g head,1990 cas...2g water neck...so im kinda stumped

 

[joyfil2001]

The 4G64 is single cam. Not sure how you have them on your engine. Do you have a pic of the engine bay?

 

[blackhawkgsx]

I Used the search button and came up with the possibility of it being a 2.4....so they say and to think that might be true because my 16g does spool rather quick but it is also blown.... Mega shaft play so i though that's why it was spooling so quick but IDK.... the guy i got the car from knew nothing about the car so.... any help would be appreciated

I know the pics are not the best I will try to take better ones tomorrow

That is definitely a 4G63 head. If is a 4G63 block, then it is not the 2.4. But, he could have had the 4G63 head installed on the 2.4 block for an instant stroker. Seeing that you said he knew nothing about the car, that is unlikely.

Also, the head looks like a 1G head, seeing that the CAS is the older round one. What makes you think it is a 6-bolt, besides the 1G CAS?

It is possible that you have a 4g63.5! A 4g64 (2.4) bottom end With a1g 4g63 (2.0 dohc) head. If so there are two ways they are put together. One is with the ultra rare 4g64 bottom end that came with a dohc, or they did what everyone else does and plugs a few of the oil/water passages on the block before bolting on the head. Either way I wouldn't complain!

The guy i got it from just perchased the car him self from a shop but had to sell because he was going to iraq...... also the oilpan identifies a 6bolt... did the research on vfaq and also just ordered an oilcooler kit with OFH from extreme psi for a 6 bolt


Not complaining just want to know what i have so when i order parts in the future i know what to order.... Thanks for the Feedback !!

So is it odd that my turbo spools at about 2100-2300 rpms? its a blown E316g

also there is alot of wire work every where in the harness like tape,solder, etc

Depends on what you mean by odd. I've seen blown turbos spin better than before they were blown. It's quite possible. Besides, EVO 3 16s are pretty quick spoolers. Just replace that turbo before you start sending fins into your engine.

As for the wire work, that's good old fashioned laziness or jury rigging. haha

To Me (I could be wrong) it looks like you have the 95-96 cam gear with the trigger plate. Maybe the owner before you put a 1g cam sensor in instead of getting a new 95-96 sensor, because they are a PITA to replace. Well not really its just you have to redo the timing.

I'm going with this guy's answer...

Look at the thermostat housing. That's 2g all the way... The 2g thermostat housing will only work on the 2g head. And vice versa, 1g on 1g...

Look at the bolt on the right side of the CAS, on a 1g head this is a stud and a nut. Looks like yours is held on with a bolt. Not a stud and nut.

So, you have a 2g head w/1g CAS... My guess is the block is the stock block too... You can check for this though... really easily: How to quickly tell a 6bolt and 7bolt engine apart

Yes as i said above i checked vfaq and its a 6bolt. there is also a bird nest of wiring every where .. when i put on my 16g the head verified it to be a 6bolt head hence the larger ports ...i know it has a 2g water neck but i guess the guy before me had the head ported... the reason i thaught the cam gears where different is because i was browsing extreme psi and came across thisEXTREME PSI : Your #1 Source for In Stock Performance Parts - OEM 4G64 Cam Gear: Mitsubishi Eclipse

and this

my exhaust cam gear has this part number
and the intake looks like this and has the part number

i just wanted to know if they are different in size compared to the 4g63 cam gear as this would mean the belt is different, so when i do the timing belt replacement i know what one to get.....

If you installed a turbo, you were looking at the exhaust ports. The exhaust ports on the 2g head and 1g heads are the same. The intake ports are where the difference is at. So, unless you took the intake off...

The cam gears are the same diameter with the 4g64 and 4g63 but the markings on the 64's gear are a little bit off compared to the 63's marks.

Check the engine serial code. Its behind the turbo towards the right side of the block. Its on a flat square surface and is stamped into the block. Its probably covered in grease and grime so wipe it off. This will tell you what block you have. If it says 4g63 and you have a 6 bolt oil pan then you have a 6 bolt 4g63. The 4g64 and g4cs are the 2.4l blocks.

 

[EclipticalGS]

If your sure the block is a 6-bolt, tell me where the turbo coolant feed line comes from. If it feeds from the block right behind turbo, then its a 7-bolt.

I know for certain thats a 2G head no matter what, but to have a 6-bolt block underneath it, the head needed to be milled (headstuds reemed) to fit.

Also, do all your front bell housing bolts meet up to the tranny?? If so, you have a 7-bolt.

The feed comes from the water neck. there is a line that comes from the water neck to the turbo, but there is a random line neer the alternator by the water pump that is plugged..... and i will scrape the grime off in the front to see the serial thanks for that idea!

Thanks for that answer thats what i was looking for and i just checked and you are right the timing marks are off and thats what i wanted to know before i did the timing belt.... but why does extreme psi's web site say if you have the 4g64 cam gears you need the 4g64 timing belt to make it work?



Ok after burning my finger i found the part number under the manifold and sure enough it says 4g64 ... so now what do i do when i need parts?

 

[DashLaflash]

Sorry to hear you burnt your finger but good thing you found out what block you have. They share a lot of the same parts but you'll want to use the 4g64 DOHC timing belt as it is longer than the 4g63 belt.

 

[blackhawkgsx]

Ok cool thanks but Im going to need a clutch soon so would i just order the 6bolt clutch? to a 4g63?

 

[eclipse gsx]

7bolt sir nah just order the 4g64 clutch it will fit order the clutch for a 2.4 sohc eclipse and there u go
