here is the 2g intake manifold next to an evo3. easy difference to see

No pics.. Hmm, yea VERY easy for us to tell.. How about you post some pictures and maybe we can help with your issue...

Although, ^^^ post is pretty helpful.. However, your "stock" 7 bolt "could" have an Evo III intake..

So, in conclusion, we have no idea without pics.. Just saying..

I'm not sure how valid this informaion is but, I've been reading on EvoM that the way to tell the difference is that Evo 3 blocks s/n start with "CE". From the sounds of he knows the head to be configured like a Evo 3 so really no pics would help identification of the block.

There's a top view. I don't know what else you guys might need. I'm starting to do some mods. I have a 20g turbo sitting here to put on but I need to know what injectors I need to get and what ECMlink. (Since they make one for DSM and one for an Evo motor)

The dsmlink setup doesn't care what engine is in the car. The dsmlink setup has to match the ecu. The biggest difference in power you would see from an Evo3 engine would be the evo3 16g on it, bigger injectors, and the intake manifold. Otherwise not much is special about an evo3 engine.

Well I have a super 20g sitting here on my desk ready to go in but I want to get an ECMlink and injectors first. That way I don't starve it and I know what's going on

What is the vin number on the block. Look right above where the trans bolts to the block.

Ok I'm not home at the moment but I'll look in about an hour. What should a 7 bolt 4g63 block start with?

From the link you posted to the Facebook pictures shows an eclipse motor. Definitely not an evo motor, looks like your standard 7 bolt engine.

Look at the intake manifold and the valve cover, they are not standard 2g eclipse 7 bolt. It could be EVO, it could also be RVR

Alright thanks for the help guys!

If you put a 20g, and aftermarket injectors on it, it won't matter what the engine is out of. It will be a 7 bolt 4g63 with a 20g, and larger injectors bolted to it. As it sits now it looks like it has a stock 2g dam t25 on it.


These aren't Hondas, their is no holy grail, most desired stock engine swap. Any stock dsm/evo1-3 turbo engine is capable of supporting around 400hp. The early 90-92.5 6bolt engines are actually capable of supporting the most power, but trying to push lots of power through a 20+ year old engine isn't always the best idea.

Do a compression test. EVO 3 motors have a 9.0.1 compression ratio. Also there is a difference between the position of the frost plugs for the Evo 3 motor versus 2g & RVR ( I will double check)

If it is a Evo 3 motor you'll probably crack the ringlands. Very common with Evo 3 motors when running higher then stock boost.

Engine Codes:

Evo 1: MX, NX, PB

Evo 2: OP, QV

Evo 3: PP, SD

My brother has a Evo 3 which the original motor blew then replaced with Evo 2 which was slowly losing compression then a RVR motor which cranked walked and finally a forged 6 bolt. So it's safe to say I know the differences.

BTW you'll crack the ringlands with an Evo 3 motor before you make it to 400WHP!!

Looks like a stock 7bolt with a evo3 intake mani! Valve cover looks like stock 7bolt not sure why you would say it doesn't! Looks like all 3 I have in my garage!

^^

Actually it's a Evo 3 valve cover

It reads 'Mitsubishi' instead of '16 Valve' unlike the stock 2G.

Sorry but that's false!! My 91 gvr4 valve cover says Mitsu just like his and its not a evo3 cover its stock! And I believe my original 95 cover says Mitsu too! I'm looking for it now to check!!

^^

It's the colour of the valve cover that makes it the EVO 3.

Have you ever heard of a bead blaster! My stock 95 is same color and everything and says mistu! Not trying to argue just saying the valve cover really tells nothing! I have 2 early 95's and they have the same covers! Also if you look at the valve cover breather nipple its bent towards the fire wall like the 1g's cover! I believe the evo3 cover has a straight nipple!

You said 7 bolt, Galant vr4s only had 6 bolt engines and yes the valve cover reads 'Mitsubishi'.

In any case how do you know what valve cover your car came out of the factory with? By now they've mixed and matched so many times.

Again, the one on the OP engine is not a stock '7 bolt' DSM valve cover. Could be an sand blasted GVR4 for what is worth or a JDM galant (I believe the difference is the little diamond logo before the Mitsubishi.

For what is worth, it's a 4G63 valve cover, doesn't make the engine an EVO 3.

Just google Evo 3 valve cover. It's not the same colour as a bead blasted one..

BTW I am not saying it's a Evo 3 motor though.....

Read my first post clearly I am the only one who posted in this thread that knows the differences in early evo 7 bolts......

Valve cover has nothing to do with it seeing that at any time one could switch valve covers whether it is a 6 bolt or 7 bolt. Your only way to tell is by the Vin stamped into the block. Other wise that all parts could swap out and bolt up.

Who's to say it's not an evo3 block with 1g 7bolt non turbo pistons in it, topped off with a Hyundai cylinder head?

The VR4 wasn't made in the USA, neither was the EVO that's why they both have the mitsu valve cover.

All 1g and 2g have the valve cover that says 16 valve at the top and DOHC 2000at the bottom. The ones with that say Mitsubishi or say Mitsubishi and have the diamond symbol are from cars that were imported or made in japan like VR4s, EVOs, RVR. If you have an eclipse with that valve cover its not the original valve cover. It doesn't mean that's the original valve cover on the OPs motor, but if it is it is an indicator that its possibly an EVO or RVR motor that along with the intake manifold.
