Sorry if this has been asked a million times already, but the search function really struggles to help on this one...
I've got chain-drive 4G32 here from a rally car. There has been some suggestion that it has a Number5 cam in it.
How would I know?
4G32 camshaft identification/specs.
Re: 4G32 camshaft identification/specs.
To answer my own question again... It's got 1 stamped into the end of it...
This brings me to my next question:
Anyone know the specs of the stock cams? On closer inspection, this one looks like a regrind, but it would be good to know.

Re: 4G32 camshaft identification/specs.
There IS a thread somewhere with a number of them listed from workshop manuals ....to various degrees of accuracy, I suspect
1 = stock 4G32 Galant 16L/GB (I think the smaller engines - or some of them at least - have #0 ?)
2 = Galant GS. By all accounts a good thing, but rare because the GS was never released here.
3 = GTO
4 = factory competition cam of some sort ... race rather than rally spec, perhaps ?
5 = factory rally cam - genuine ones in good condition are rockinghorse poo.
6 = stock 2nd gen Galant (GC/GD), and also stock Lancer 1600GSR (it's what's in mine, which is a Jap import GSR motor). On paper, specs are very close to #2 profile

Re: 4G32 camshaft identification/specs.
So what's the go with aftermarket cams? Are they stamped 1 to X for their according stages (stage 1, 2 etc). Or would I best ring the manufacture?
Also. Could I have a pic of where to fong the stamp?

N/A ALL THE WAY
Re: 4G32 camshaft identification/specs.
The terms "Stage 1", Stage 2", "Stage 3" etc are basically meaningless in terms of cam spec ..... they are just marketing terms used by some cam manufacturers/sellers.
A "Stage 1" from one manufacturer will not necessarily bear any resemblance to a "Stage 1" from someone else.
Any decent cam producer will describe their cam items of lift, duration, lobe centre, etc.

Yea.. Well I go by the old terms. 30/70. What does that mean?

Have a wade through this thread http://www.sigma-galant.com/viewtopic.p ... t=cam+spec and see if you can separate fact from opinion !Spac2 wrote:Anyone know the specs of the stock cams?
Bottom line .... none of the factory cams other than #1 or #6 are readily available in Australia. Easier & more effective to buy something aftermarket off the shelf or get one reground.
Re: 4G32 camshaft identification/specs.
So me having 2 #2 cams is that rare ?
Re: 4G32 camshaft identification/specs.
Relatively, I guess .... seeing the #2 cam never came out in anything here. That said, there were a lot of s/hand Jap motors imported by companies like API and others in the late 70s/early 80s, so there would be a few still about I assume.So me having 2 #2 cams is that rare ?
They were originally fitted to the Japanese spec Colt AIIGS (4G31 twin carb) and Galant 16LGS (4G32 twin carb). I guess the 16LGS sedans & hardtops sold in NZ would probably have had that cam also.
