4g69 build.

I've a 4G69 87mm bore block with 100mm standard crank. Has anyone on here built one? Are parts readily available if I build it?

There are two ways to look at this IMO from a bottom end point of view. A 4G69 is:

A 4G63 block with 100mm "stroker" crank and bored out to 87mm

or

A 4G64 bottom end but with 6mm shorter deck height and 150mm rods

Its kind of the worst of both aspects as you have narrower cylinder walls due to 87mm bore (weaker) and don't have the extra deck height so its a bit pointless really..

it is also more "open" on top deck and has the lightest 100 mm crank. There was a build on evom. With 87 mm bore i think boring is out of the question... Might be a interesting way to a cheap 2.3 for those that are not too power hungry.. although there are better cheap block options out there..

This was very cheap. What other block options are there other than 63 or 64? It's supposed to be a cheap build so I will try anything really

I knew that would be the first response It's nice to think of them that way at the beginning, and then just forget what they cost as the build continues.

if you want cheap 2.3 then yes, g69 or g64. Other options are not so affordable..

the 4g64 block was also used in other makes of car not just mitsubishi

you just have to keep searching for one, they will be cheap enough if you find someone breaking the car they came out of

It would be nice to know what was considered a reasonable price nowadays for a decent spec’d engine. I had a 2.3 built years ago by a reputable tuner and was pretty dear but great quality and that was using a new oem crank. And me suppling a full 8 long engine

I bought a complete g64 for 150 eur. A complete outlander g63 dohc NA engine, which is a nice bassis for converting to evo 8 engine (with aftermarket crank and some headwork) is about 700 to 1000....
g69 was used in some citroens, like ccrosser, but those are hard to find in petrol version.. LOL

I recently finished a engine forge and complete body strip and overhaul on a friends 9, with numerous mods... As that project dragged on, I never made a sum of all costs, nor did I put the price on my labour.... However, I recently had to do so because someone asked how much it would cost on his car, and frankly speaking I was shocked.. hahahaha
