I know this has been beat to death but Im having trouble finding good info. I'm thinking of either scrapping the Evo all together and selling with a seized motor OR just building a 2.2 stroker. Looking for any advice on building/ parts or any info at all on them. Would love some numbers and facts on this setup. Thank you in advance.

 

The short answer is the best engine build is the one that is designed around how you use your car.

So before you get all bogged down in the pages and pages of info about the pros and cons of 2.0-2.4 4g63 Engine variations, you should figure out your budget and what the intended use will be.

Then, find a reputable builder, ideally one close to you so you can take the car to them to handle the rebuild/install/tune all in one shot, and tell them your budget and how you want to use the car.

This way you will end up with the build that is best for YOU.

 

I appreciate the advice, and i made a decent bit of power on the stock bottom end with a few upgrades, and the bottom end gave up on me. So now instead of just building the 2.0 I wanted to do something a little off the beaten path, my builder suggested a 2.2. But before I just jump in buying parts I wanted to hear from people who have the stroked motors and see how they like them. I've read tons of info on it but no real explanation on how people feel about it who have them. But I have already taken the necessary steps in finding both a builder and a tuner (both I have experience with before) and a rough budget estimate.

 

If you're on a budget a 2.3L will be your cheapest stroker motor because you can pick up a used 4G64 100mm crankshaft and it won't cost you all that much. The issue with running a 2.2L is you need to find a 94mm crank and they're significantly more expensive than a 4G64 crank. For what it's worth though 2.2L are beastly setups because they can still rev high while providing the extra displacement. English Racing sells a really nice 2.2L rotating assembley which includes a K1 crankshaft, R&R rods, and Wiseco pistons.

 

Cant you stroke from the evo motor 2.0 to 2.2 & 2.3? Also I'd like to do a 2.2, want to hear which setup is good.

 

If you can afford it, 2.2 is a great way to go. It is a proven design which offers the best of both worlds (displacement + high revs). Like someone else mentioned ER offers a really nice 2.2 kit.

You should also consider cams (like GSC S2's) and a valve job while you are at it. Build it right the first time and then leave it alone.

 

Yes the Evo 4G63 2.0L can be stroked to both 2.2L and 2.3L. the 2.2L uses a 94mm crankshaft while the 2.3L used a 100mm crankshaft

 

I think what nemsin is saying is that the motor that will work best for you is what works with your supporting mods. Your head and cams and most of all your turbo should all work together.
For example, it is pointless to build a 10k rpm 2.0 if you are going to use a turbo that will only be efficient until 8k rpms. In this instance you might want a 2.2 or a 2.3 to gain the torque and spool that the higher displacement will provide while your engine will out rev the turbo's range.

I am having a motor built now and I decided to go with a 2.3 but I am going to be using a 3B turbo. I could have gone the 2.2 as well but with this turbo the 2.3 gives me enough RPM and also creates that down low power and faster spool.

Think about the whole package when you decide.

 

Money isn't a concern, I'm happy to spend what it takes to get the most reliability, etc. Not sure which 2.2 to go with, here is one http://www.nitto.com.au/products/strokerkit-4G63-22.html?vehicle=mitsubishi

Opinions^

 

I have a 2.2LR love it! It is a more expensive build for sure, but the bump in displacement and the capability of high revs exceeding 9K is worth it. I did a writeup on my 4g63 2.2....Although this engine is best suited for someone using a big turbo that needs the high RPM and still take advantage of the torque provided by a higher displacement engine. If you dont plan on putting a turbo on the car that needs breathing room above 8500 and you want to do a stroker do a 2.3.

 

Everyone here has you covered already. Match your engine with your turbo with your cams, etc. Decide what your ultimate goals are going to be and go from there.

I went with a 2.3L for a reliable, well rounded car that could put up decent numbers in drag, AutoX, or road racing if I choose. Not looking to break any records, just a fun street car.

 

The head already has valve job, springs and the s2's lol. and I definitely don't plan on taking the cheap route. I was thinking K1, Manley Tt's and the weisco 1400s. I just wanted to make sure that the setup was worth the trouble and money involved. I'm also going to use my pte 6262 on it and running e85. I've done quite a bit of reading since the first post and It seems like an awesome setup

 

Any videos or graphs on your build? Id love to see one in action

 

Just remember its as important to have a reputable person/shop assemble the motor as it is buying reputable expensive parts. What good is a $4,000 dollar rotating assembly if it's put together like sh*t.

 

here's a thread from one of the most reputable 4G63 tuners you could meet.

https://www.evolutionm.net/forums/ev...back-2-0l.html

all about strokers, pro's and cons, and probably talks about more than just 2.4's; though I haven't read it in a while.

If you want a FUN (and easy) car on the street, aren't concerned with setting 1/4mile records, and aren't going to use a gigantic turbo, a 2.3 or 2.4 are the way to go. 2.2 is great, but you don't need the rev's if you aren't racing (I assume). And as far as revs... I accidently hit 97xx rpm with my 2.4LR at the shootout this year; it's been fine since, and I have no concerns hitting near 9000 on the regular.

Decent parts + superb assembly + great tuning = good to go. screw the crank weight, piston speed, rod/stroke ratio, etc. etc. etc. stuff. leave that to the racecars. If you want a street car, treat it that way; 2.3/2.4 is perfectly fine and capable!
