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.
DSM: 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.
(now that I have the power I can do it myself.... muh ha ha ha)
