4G53 vs 4G63 cranks?

[Jon Lane]

Can anyone tell me the differences between the 4G53 and 4G63 cranks?

Update: I'm aware that the 4G53 is roughly a 2.4l motor. I'm trying to understand why an 88mm crank I have is stamped "53" on one counterweight and "G" on the other. Was the 4G53 an overbore 88mm-stroke 2.4l?

I believe the "3" in the 4g53 denotes a 2.0 liter motor, i'm not sure
not sure how much this will help, but I found this

4G4x "Neptune" — 1.2 L to 1.4 L straight-4 engines available in the Lancer and Galant in 1979.
4G5x "Astron" — Offered from 1972 in capacities from 2.0 L to 2.6 L, the Astron family pioneered the modern use of twin balance shafts in a straight-4 configuration. The system, introduced in 1975 and dubbed "Silent Shaft", built on the patents of Frederick Lanchester which Mitsubishi had obtained, and proved a lucrative venture when it was licensed to numerous other manufacturers.
4D5x "Astron" diesel — Also part of the "Astron" family, the 2.3 L was the first diesel engine to be fitted to a Japanese passenger car. The subsequent 2.5 L version, introduced in 1986, is still in production, a popular choice in its line of pickup trucks where it is regarded as rugged, reliable and inexpensive to maintain.

Another question: Is there any difference in either the crank snout of front main seal between the 7-bolt 4G63 and 4G53? I'm about to replace the seal for the second time in a 7-bolt 4G63 using a new OEM 4G53 crank.

Well from what I can find the 4g53 has 98mm stroke.
So if it will bolt in your 7 bolt block, your pistons will be ot the top of the block by appox 5mm

Also it looks like the 4g53 was in production from 7/1978-12/1983

Another thing is it takes a totally different set of bearings.
