Well, I'm no wiseman but the EVO III heads are like 2G heads...small intake ports. Make sure the head has a "6n" on the exhaust valve for confirmation that it is an EVO III head. Don't wanna get jipped, right?

Awesome, thanks! Talk about a sleeper upgrade, bwahahaha! So I could still use my 2G's intake manifold

Try to get your hands on the EVO III intake manifold as it has shorter runners. There will be a difference with the intake manifold but if you use the 2G manifold, it won't be different...at least on the butt dyno. Good luck!

not to jack this thread but is the bottom end the same or is that a little different too? besides six bolt to seven bolt.

Wait, I'm not 100% sure. But I know that the intake manifold and exhaust manifold have larger ports then the 2g. So wouldn't it only make sense that the Evo3 head would also have larger intake and exhaust ports???

I believe the intake ports are the same. The EVO III intake manifold just has a larger plenum and shorter runners. The bottom end has 9:1 pistons....and something else too but I can't remember. It was little though.

why not get a 1g head?

Never underestimate the 2G heads as they are also very capable.

I'm sorry but i don't think that either of you are right. The evoIII motor has the same head as the 1g eclipse. The evoIII also came with a cyclone intake manifold big 16g and 510cc injectors. it was a 7-bolt but other than that it is the same as a 1g head.

Um...sorry but no. It's more like the 2G.

Not to burst anyones bubble but the EVO III didn't come with the cyclone manifold, that's the JDM Galant VR4

Everything you need to know about JDM 4G63's and the cylinder heads they came with.

Here to make it easy


EVO Motors: The valve covers of the EVO 1-3 motors will be a kind of titanium color. They are the same as a US 2G motor with nothing fancy. They have the smaller 2G style intake ports, a small runner intake manifold with a larger plenum and a larger throttle body than a 2G motor. Still they are hard to find. Many are from other 4G63 powered cars and can have small 13G sized turbos. They will not bolt into a 1G because there are no provisions for the front roll stopper motor mounts that bolt to the block. Everything in Japan from 94 and up has the front and rear roll stopper motor mounts on the transmission 2G Eclipse style. Many people are running around yapping about how they have an EVO motor in their car. If it bolts into a 1G, it isn't an EVO motor.

When calling these guys you may have to deal with some heavy accents. We ask for "four by four" on the transmissions. "Four wheel drive" can be confused with "front wheel drive" sometimes. AWD trans go from $450-700 including transfer cases. Feel free to to try to cut a better deal if they have the motor and tranny still in one piece. They will often discount it a bit if you buy both. Be careful about what trannies you buy. In Japan they have several different final drive ratios. Anything with close ratio gears or a LSD front diff will most likely have the wrong final drive ratio. Any tranny with a strange vacuum actuator hanging off the front will be very old and has the wrong gear ratios also.

There is no way to determine the mileage on these. They will always quote 40,000-60,000 but there is no way to really know. Most are very clean. They guarantee the motors and trans for 6 months and usually 6,000 miles, but just the parts and not the labor or shipping. In Japan they have very strict licensing laws and regulations which get older cars off the street at a young age. Do you really think there are 12 year old GVR4s getting scrapped with only 40,000-60,000 miles on the odometer? I don't.

The EVO III intake has shorter runners and a smaller plenum.
Here is mine.

Now that that's been taken care of. I've heard that the EVO 3 cams have more lift than the 2G's, is it more than the 1g's? This is making me lean more towards a whole 1G head/intake manifold & TB swap...

Did you even read the post before you?

They are 252 cams. Send me your 2G head.

All of these cams have a 252* duration.

There is no difference between Evo 2 & 3 cams and 1G cams. VR-4 models are understood to include US market 1G DSM's as well

All VR4 models/Evo 2/Evo 3 Exhaust: MD128973
All VR4 models/Evo 2/Evo 3 Intake: MD128974 (option: MD335754)

The oddball is the Evo 1:
Evo 1 Exhaust: MD193148
Evo 1 Intake: MD193147 (option: MD335759)

It should be noted that Evo 1 cams are less aggressive (less lift) than the others. A CAPS search shows 2G cams to be the same part numbers as the Evo 1 cams.

Bottom line:

1G/Evo2/Evo3 cams, all the same.

2G/Evo1 cams, the same.

1G/Evo 2/3 cams, more lift, duration is the same for all.

And to further bottom line:
1G/Evo 2/3 cams are the most desireable of the group?

What will they "utilize" (aka bum) off of the Lancer Evolution III next?

So you're saying that putting 1G cams in a 2G head, not only will I get more lift and a longer duration for the intake and exhaust, but I will add that on top of a higher velocity head (1G vs. 2G velocity flow)?

does the evo 3 have the crankwalk problem like the 2g 7 bolts? and how would the bottom end react to evo 5 cams?

I've never heard of the EVO's getting crankwalk. But you can't put any engine parts from an EVO 4 on up because the motors are reverse.

no i was lookin at an evo3 motor and thought since its a 7bolt they might have that same problem

okay so i just need a yes or no answer....

I found a evo 3 head, turbo manifold and It also has the throttle body,coil packs, and injection rail with injectors.
all for $100


Is it an upgrade? Should i get it?
