4g64 Or 4g69
Ok guys i need some help deciding on what block to build i want a DD/Track with about 600whp to 650whp i have an evo 9 and i know that the 69 has the oil feed for the MIVEC so would that be a better? But the 64 has been used alot more so i have no idea at this point give me you input to help make up my mind thanks in advance.

The 4g63 (LOL corrected my stupid post) is what comes in the Evo 8 & 9. The Evo 9s require an oil line for MIVEC - if you have a stock 4g63 block from an Evo 9 then you don't need to do anything. If you have a 4g63 from an Evo 8, then you need to machine the block (tap a hole) to accept the MIVEC line. The 4g69 is a stronger block, has oil squirters already, and requires no modifications to work with your car / head / etc.
The 4g64 block can be found cheap, requires some additional machine work, can give you a "better" rod/ stroke ratio, and requires some additional work (timing belt and water pump) to get it to work. I was interested in this route because I thought I could build a motor a lot cheaper, but in the end it was about the same as the 4g63 route.
If you go the 4g64/4g69 route, make sure you deal with a company that knows what they are doing (and has done the conversion before)....

I have no idea what Rock is saying, but the 4g69 motor has been used to build the highest output and best running motors for many a year.

HUH??? The 4G63 comes in the EVO's
The 4G69 was available in the following
2003–present Mitsubishi Grandis
2004–2006 Mitsubishi Lancer (Non Evolution)
2004–2006 Mitsubishi Outlander
2004–present Mitsubishi Galant
2006–present Mitsubishi Eclipse

Both blocks will give you the 86.5mm larger standard bore and 100mm crank, but the 4G64 will give you 6mm more deck height which will enable you to increase your rod length from 150mm to 156mm. This will give you a better rod stroke ratio....1.56 vs. 1.50 rod stroke ratio. Ultimately, the 4G64 should give you another 500rpm added to your redline. I'm pretty sure the new 4G69 comes from the factory with a stroker piston design...so with the stock 4G69, it's like taking a 4G63, adding a 100mm crank, boring it to 86.5mm and adding in a stroker piston which shifts the pin up 6mm. Using a 4G69 to start with, would be a great idea if you were happy building a slightly larger displacement 2.3liter.....you would just need to replace pistons with stock bore 86.5mm forged replacement stroker type pistons and quality 150mm rods. The 4G69 already comes with a 100mm crank. If you wanted to build a 2.4liter, this would net you slightly more displacement. It would consist of using the 4G64 block, which comes with a 100mm crank. You would need 86.5mm pistons preferably in a stroker design and forged, the same ones used in the 4g69. Lastly, you would need a 156mm quality rod and in the end would net you more displacement and higher revability. With all of the above, you can increase the bore slightly to 87mm or 87.5mm, but for reliability stick with the stock 86.5mm bore if you can. This will also enable better headgasket sealing. Hope this helps!

The benefits of th 69 are larger coolant passage ways and same deck height as the 63 eliminating the need for offset adjustable cam gears/modded mivec gear required to run the 64.
Shown here in order left to right to illustrate coolant passages are a 69 block from an '05 lancer, a 63 block from an '03 evolution, and a 64 block from an '02 galant.

If you want to build a Stroker for a Evo what would you need?
4G69 Block
150mm Manley Rods
87mm Wiseco Piston (Stroker Style)
ACL Race bearings
ARP studs
Any other modifications? will a build 4g69 swop out for a Evo IX 4g63

there are many stroker designs depends on the block im still a huge fan of either 2.3 4g63 or 2.4 4g64. I hear what they are saying above loud and clear but tons of information and packages you can buy on the following types of builds if you want to do a 4g69 then again more power to you and good luck

depends where you get it from really and what kind of 4g64
std 2.4
3000-4500 depends who you get to build it (SBR,Map,AWD,ER,Magnus,JMS)
LR 2.4
5500-6200 depends who you get to build it(SBR,Map,AWD,ER,Magnus,JMS)
Some of us paid less then that for a built 2.4 but all in who you know really nobody requires a core but most will take your 4g63 off your hands if you dont want it and get you core credit. Any other ?s

Wow I was under the impression that a built 4g64 was a cheaper alternative to building a 4g63. As a comparison, you can get a 2.3 4g63 from Buschur for $3300. I was assuming the 4g64 to be less.
