As per a post by KJMERKEL69
There are basically two Colt/Mirage/Summit bodies that are most commonly discussed here. The following apply to North American models ONLY
- - 2nd gen: C1x body code: '85-'88 US-spec Colt and Mirage sedans and hatchbacks, '85-'90 Canadian Colt 100 and Eagle Vista sedans and hatchbacks, '88-'90 Colt wagons
- 3rd gen: C5x (hatchback) and C6x (sedan): '89-'92 US-spec Colt/Summit/Mirage, Canadian Colt 200/Summits/Mirage
The engine codes commonly in discussion are as follows:
- - G15B: C1x 1.5 carbureted
- G32B: 1st gen & C1x 1.6 SOHC EFI turbo
- 4G15: C5x, C6x 1.5 EFI
- 4G61: C5x, C6x 1.6 DOHC EFI
- 4G61t: C5x 1.6 DOHC EFI Turbo
- 4G63t: DSM 2.0 turbo engine which is a direct bolt-in replacement for the 4G61/t
- 4G64: 2.4 SOHC found in Galants, among other models
The engine codes are formatted like this, using 4G61t as an example:
4 = number of cylinders
G = cylinder block material (G = cast iron, A = aluminum, D = diesel (not US)
6 = engine family
1 = individual model within engine family
t = denotes turbocharging
Generally speaking, parts are easily interchangeable throughout an engine family within reason. That is to say, smaller pistons will not work in a larger engine, but that should pretty much be common sense. Across engine families, interchangeability is pretty much nil with the exception of some MPI electronics, but even that is minimal.
: Diamond Star Motors, Chrysler/Mitsu joint venture which created the Eclipse, Eagle Talon, and Plymouth Laser in Normal, IL. Also apparently produced a handful of 4G61-powered Mirage GSs and Summit GSs.
I was about to post that thread in response to a question but realized the wording was a bit awkward. If there's any inaccuracies or omissions, please correct them as necessary.
