when i started this project i had a budget mapped out. in that budget was $1000 for rear diff, rear disc, 5x114.3 stud pattern, fitting and tail shaft mods. i reckon i can have it in for $700.

for interest the whole budget is $2500, with me doing everything from wiring to welding stainless exhaust, to gearbox rebuilds. and that includes buying the doner vehicle and includes selling any left overs. i am on track with the car driving fine already and easy $1k left for diff.

to wind back the clock further, i had a my96 wrx wagon, and i sold it for $8k. i reckoned i could have the ute purchased, converted and painted with a bit of change if lucky. i paid $3500 for ute. so i still on track.

stay tuned guysl,

i have a dream...

[BMGTZ]

rear diff suggestion.

JDM ae86 /sprinter{lsd and discs}. then a t18 diff centre which i thing is 3.9.

or if you want...to stay drums and easy. T18 diff drum to drum should be less than a six pack ....but is open centre.

both are 4 on 144.3

thanks brian, i will look into them, you are a font of information.

i have a little time for the ute, so i pulled rear wheels off and measured the width from wheel mounting flange to same on other side. it is 1577mm wide.
this is miles from other measurements of 1460. i not sure where others have measured from, but it looks like from inside backing plates. anyway i off to the wreckers to look at diffs.
my figures from a chart of rim offsets and car specs for track width suggests that i need to look at vn-vt diffs, and prob some falcon stuff too.

[jack be nimble]

so i got a diff, its from a el-ed falcon. the scrap metal man was about to pick it up just before i grabbed it. it is 1560 wide. it is 3.08 ratio so i will have to change the gears. the chap at the wreckers says it has seized wheel bearing, but it was handbrake locked on.
it is basically bare with brakes but no calipers. any way plan was to use the long axle out of it for use in a AU axle, but i think it probably not worth the bother for 18mm. i reckon i can make at least half of it by fiddling around. i dont want to use spacer plates as i dont want to lose the centre register. maybe i can space the axles out slightly (5mm each ish) and just cop the rest. with smaller tyres they should clear the inners ok.
there is 0mm offset on it and thats why there is a short axle and a long one

so i pulled the plasma cutter out and trimmed all the mounts off the diff ready for grinding. even got the daughter to have a go as well
i have access to another diff that has leaf hangers on it, so i may have to get it and cut it up for the hangers.

may have ballsed this up as a 3.45 ratio diff may not fit in this housing, something to do with pinion bearings or something.

the m21 dash arrived the other day, so i have put that in and now the tacho works as well as the fuel gauge. so thats another couple of jobs done

had a issue with the idle, it seemed too high and now i have a tacho i can see that it was about 2500 when cold and 1700 warm. i saw that the throttle was almost fully shut and the screw was almost in fully. so i taped off the 2 holes in the throttle body. then it wouldnt idle at all. this told me the issue was in the cold idle up or the stepper. if i screw out the idle screw i could hear the stepper trying to adjust the idle so i figured the cold idle up was the culprit. anyway i swapped it out with another and now i have 1100 cold idle and 950 warm. sweet.

pulled the gtech out of the shed and tried it out. regular readers will remember i cut a 19.5 or something with the old 1.5
best of 3 runs today got me a 15.5 @ 92mph with a 2.5s 60ft
1st gearchange is just before the 60ft mark. need to try again either starting in second or holding 1st a touch longer. i was short shifting into second to avoid the wheelspin.

mate ....most of the kids here wont know what those cars look like with googling

[EVL20T]

I know all of them

Then again i am 30 y/o lol

[ONPSI]

Lol I like how 90% are pre 1980's...you wannabe quicker the most of them!

[jack be nimble]

where i pulled the times from was a list of muscle cars from 1991 and older. there were some newer than 1991 but not a comprehensive list. interesting that 15.5 was shared by hdt commodore (prob vc or vk)
i should have put the link in there as well

maybe good for another second with the rear diff in, i think 90mph is good enough for mid 14s?

Ahhh the little scamp that is the Jumbuck.
Keep at it mate!

[ted]

I know all of them and im 25!! hahaha

[Chaser]

same but im a spanner lol my dad had a few on that list and amongst his mates i think the list is covered lol

[jack be nimble]

well i have a diff, pulled it from a AU xr6, is 3.45 lsd. is 40mm too wide, so i am going to cut the drivers side 40mm (this will give the required 20mm offset on the pinion) and using a el drivers side axle that will need shortening 14mm. the splines are cut long enough to handle this cut.
price: $100 for au diff and 50 for el diff.
have to cut some spot welds out where the centre is welded to the axle tubes. they are mighty hard, had the drill press on them and all. ordered a carbide cutter and we will see how that goes...

[BMGTZ]

how big is your drill press mate...have you seen mine?..I know your away now but when you get back, drop over he and try my old girl.

she is old but has some grunt!


my wife says that....describes me as well. well the old part any way.

[jack be nimble]

thanks brian, not sure what i letting myself in for, but if there is a grunting old girl there....
my press is a $90 from marlows when they were still around. was cheap even then. even when its on slow, it still too fast for a 25mm cutter.

[BMGTZ]

mmm marlows. well that makes it a least 10 years old......when did Super cheap buy them out?

Mine is about 40years old. it needs two guys to lift the base with the back. I reckon its at least 125 kg the whole thing.

any way....let me know if you want to try it out. I probably wont be able to assist but will more than likely be home for three weeks from the 23.

I get that shoulder done then...I think I told you about that.

[jack be nimble]

yea, supercheap bought them and then they reopened as malz 18 months later. sweet, book me in, by the time i back, you should be well enough for me to wheel you out into the shed. certainly the mrs will appreciate the peace.
um, sore shoulder?
was that the time you tried the pike entry to the concrete floor with backwards half and a twist?????
not sure i heard about that, can you tell me again just in case. i wont laugh
its not that its funny, its the way you tell the story.
