Hello everyone,

My name is Eric, and I build and race Honda's but I decided to buy an EVO for my wife. It was really for me to drive but what better way to buy something then tell her its for her.

So we purchased a 2003 Evo VIII






I purchased knowing I had to repair the motor.The crank is damaged #3 rod bearing looks like it oil starved and started knocking. The crank looks burnt for inches from the rod. So here lies the real problem, the evo did not appear in Canada until 2008 making finding a motor to get a crank not very easy. I can get a 4G64 from a 2003 eclipse very cheap.

I would put rods and pistons and whatever I need to put in!!!

I have used the search function but I find confusing info.


Here a few pics for fun

 

Should I use the crank from the 4g64?
Or use the 4g64 block?
Or get a stroker kit?
Should I eliminate the balancer shaft?

What do you recommend very much open to suggestions

Save yourself the headache and just get a kit from Bushcur.

 

If the block is fine, just get the 4G64 crank with 150mm rods and pistons that has the wrist pins located 6mm higher to clear the 4G63 block. Pretty much, a custom stroker kit. The pistons are labeled "2.3L stroker pistons" to make it easier to find them.
If you want 2.4L, get the 4G64 block with the crank.
If you're new to the stroker world, you can get a kit that has everything for you to do it.
Yes, get rid of those balance shafts and replace one of the shafts' with the AMS eliminator kit. I've seen those shoot out of the block before and it is not pretty...

 

what do people preffer

or is there other options???

 

where do people buy there oem parts online?

 

Mitsubishiparts.net. ask for Russell. source a 2.4 block from any 4G64 motor and through some rods/pistons in it.

 

STM, MAP, or the dealership.

Between the 2, I would get the AMS package with I-beam rods if you're planning on running big power.

Otherwise, you can source a 4G64 crank for $225 shipped, pistons $600, rods $600 (unless you went with H-beams, which would be well under $600), bearings and thrust washers $100. That's about $1500 if you make your own kit by buying the parts individually.

 

To answer your question certain 2.4l blocks will work and others wont so be careful which you decide to choose.

The standard 2.4l crank has been shown to hold up well and there is no need to go aftermarket if you have a good one. Going with longer rods to help stroke ratio is also very popular if you have the cheddar.

You will need to adjust for the timing of the taller deck of the 2.4 block vs. the 2.0,

You will also need a water pump spacer or a modded water pump.

There is a few very good build threads on here that can help you with clearances, etc., if you build it yourself. Here is one...https://www.evolutionm.net/forums/ev...-customer.html

Otherwise there are many excellent shops to help out. Everyone has their current favorite. I prefer English Racing due to how much Aaron helps people out and the wealth of knowledge he has.

Welcome to the community.

 

so if I get a 4g64 block I need to also get cam gears and a modded waterpump

so if I use my 4g63 i do not need cam gears or modded waterpump to use a stroker crank

 

No, as long as you are using the 4G63 block that comes with a evo 8 you are good to go. The 100mm crank will require different rods, pistons, etc. Just be careful and specific when ordering. There are a lot of great deals in the vendor section.

Depending on the rods you may have to notch the block for clearance.

I also forgot to mention that the 4G64 have a larger diameter cylinder than the 4G63 so some also modify their heads to bowl them out to get the most out the the 4G64.

 

my oil pick is stuffed with bearing pieces, do you guys clean the oil cooler? change it? New oil pump? motor has 90,000 miles

 

thanks everyone for the advice and knowlege

 

New oil cooler and pump for sure.

As it is said "Do it right or do it twice".
