Yeah I'll throw the 300kpa fuel reg and ghia ecu in when I get the tickford head installed,
But when I get the 3.45 diff installed I'll get the speedo trans done also..
It will take abit of time to mod as I only work part time and I'm a peasant!! Lol
I know changing the diff it's not gonna make my car the fastest thing on the road, but I just look at it as if each mod will improve the performance slightly..
Seriously thank you very much guys for the advice you have given, it has and will be a huge help for the future when modding my ef fairmont!!

I've thought of a good way to describe manual conversion, diff ratio change and Higher Stall converter:

- Manual conversion is like changing the front cog set on your mountain bike - with the biggest benefit being that the lowest cog is smaller than the auto one, and the biggest cog is a bit bigger - as well as manual selecting of course.

- Diff ratio is like changing the rear cog (imagine car is like mountain bike with only one rear cog) - ie. going from 3.08:1 diff to 3.45:1 is like putting slightly bigger cog on the back.

- Higher Stall converter is like being able to stand up on the pedals where with normal converter you can't stand up.

I know the stall converter example isn't really as directly technically correct as the other two but I think it quite adequately describes the result anyway.

Pretty good analogy but there is one bit I spotted - the 4 speed auto's top gear is actually slightly faster than the manuals 5th gear.

{DESCRIPTION}

Good point! - I hadn't ever really paid attention but now that u mention it and I remember the cruise figures ur quite right. Also I had the rear cog back to front - lower ratio means larger rear cog - more teeth for same rotation.

Sorry,
Would you guys suggest changing the "stall converter" ( don't really know what it is) if I'm swapping the diff from a 3.23 to a 3.45??
I have all the bits and pieces to do the swap eg;
-3.45diff
-speedo transducer (22 grey)
-ef2 ghia ecu
-300kpa fuel reg
- and tickford head
Is there anything else I need to change/ swap over??
Cheers

Is that just the tickford head...what about camshaft?

You don't really need a stall converter. Stock one should be fine. But if you want good take off and the ability to stall the car for say drag racing/do burnouts...then yes, upgrade that while it is out . Pretty sure XR/standard converters were the same though...

if your doing the head, might as well chuck a 977b in as well, or if auto, 1673

It's just a reconditioned tickford head,
1 last question I am installing 3.45 diff, 22grey speed trans, and ef2 ghia ecu before installing the ticky head. Will the car run rough/ sluggish or anything? I only ask because I can only afford to get the diff done first.
Cheers

Wrong post guys sorry

I looked. I LOL'd

And by the way a stall converter doesnt exist.. you dont convert stall. <- think about it.

you convert Torque! Its a High Stall torque converter.. just sayin'
