Wow, good job, and finished by 11am......
So are you going to swap these straight over crossmember and all?
Should bolt in pretty quickly (just a heap of wiring etc to do then)...
The transfer case looks pretty substantial.

Was done by 10:30 just took some time to put tools away then get back up to the house :)

I have to look at a High Stall get that in there then bolt the LS onto the Subframe and I'm good to go, I want to sort all of the wiring before I refit the drivetrain though so that means getting the car off the hoist.
(a mate is friends with the guys that own Dominator)

I have a pair of trollys I made to move the Lathe and CNC Mill so I can drop the car onto one and wheel it forward to get enough room to pull the entire dash..... can't open the doors far enough while it's on the hoist, only just had enough room to unhook the wiring behind the left kick panel!

I need to buy the V8 AC Hoses/lines and 4x V8 02 sensors as the plugs are all different, more than likely a couple of other bits and pieces as well..

I milled the Coil pack stands down on the rocker covers so I need to turn up some spacers for them then fit the new boots on the MSD plug leads.

Great build, keep up the posting.

The only driveline trouble you could have is 2nd gear band burning if you pump her to over 400 flywheel kW, after this you will need a built auto.

Always wondered why Holden didn't put out an AWD Tonner, would be a hit for sure.

May meet at an event one day, you never know.

AWD Tonner vs AWD Addy, sounds interesting.

Would expect the tonner to have a weight advantage.

Cheers

Thanks for jumping in Steve I'd hoped you would sooner or later,advice/tips are always welcome!

In stock trim you'd be wrong by about 70 Kg's :(

With the lighter Tray I'll be a bit under you but that will depend on further mods!

When I do the power up I'll go through the Auto and address any weaknesses but for now it "should" be happy enough at stock power..

Today!
Damn cold here today so another CBF'd day ;)

Just ordered my High Stall and a bunch of parts from Holden so another trip down in the Whale tomorrow to collect everything!

Great thread,luv the daily updates.

Regarding the box & this question would be on behalf of a fellow LS1er,any plans for a manual conversion? Have you looked at this as an option?

Really glad you're enjoying it, it helps me keep active and organised and it's always good to get opinions, questions along the way.

I actually prefer an Auto so no plans for a manual, I did that in the last project and soon as I got to 340 rwkw getting a streetable clutch became problematic, ended up with a pig twinplate that spoiled the car, swapped over to an auto and have never looked back.

Last time I ran a Toyota 4 speed auto with a PCS controller and the T04z/L98 combo so I'm interested to see just what I can do with the 4L60 and HP Tuners, add to that I'm trying hard to make this project s Bolton/PlugNplay as possible so that rules out a manual conversion!

Thanks Gee!

Like your Avatar, HQ Coupe was my first car so remember that view well :D

Today!
Well that was a fun day.....
Rang my Holden guy this morning all my parts were in then rang the guys at Dominator Convertors and it was ready to collect, special build and done in 2 days gotta love that!

Stopped at Dominator first and had a chat to Jason the owner about the project, he told me the V6 trans has a weak point in the input shaft and the V8 ones run a bigger Shaft (guess which TC I ordered... DOH)

Rang my Holden guy on the way over, not real expensive but NONE anywhere in the country... DOH 2

Rang Dave and sure enough he had a trans there he got as a spare, minimal haggle later and we'd reached an agreement on a swap of parts so I went to Holden collected my parts and headed back to get the trade parts from home then headed across to Daves, that was a 450 Km day again... I'm beat just unloaded the wagon time for a coffee and TV.

Today!
Pulled the V6 off the front end then slung the Crossmember on the Tractor and took it outside to pressure wash the 60.000 Km's of crap off.

You're getting a nice assortment of parts...

Yep there's a bunch of small differences between the V6 and 8...

Think I pretty well have it all now though ;)

Today!
Had a Bud up here today doing some wiring on his Soarer, I figured since there was nothing on TV I'd go put the Front End back in the Tonner, gotta love how Idiot proof Holden have made it, huge improvement on the last Commodore I owned (1979 model) 20>25 mins and it was back on 4 wheels! :)

Today!
Spent the day out in the front paddock ripping out tree stumps with the Tractor, some Genius thought it was a good idea to cut them off flush with the ground and over the years there's been some errosion so each time you Mow it's like a minefield....

Only one of em put up a serious struggle and after bending the bucket tooth I dug around it some and cut it with the chainsaw...

Other than that I tidied up the shed a little, I have to go to one of the bigger towns tomorrow to collect a Torx Plus Driver so I can pull the Bell housings off both Trans then swap out the Front shafts/Drums/Stator shafts.

Once that's done I'll start pulling the Dash out of the Tonner so I can install the new Main loom ready for the L98.

Today!
Had to go to town today so did a run around trying to find that Torx Bit....

bzzzz tried 10 places and even got hold of a SnapOn guy and they're nil stock, I found one Hardware suppier that can get stock so it's being posted down end of the week/early next week..

WTF were Holden thinking using this hardware... I mean really..

yep , they're a pain , the right angled torx key ya need for the airbox removal is a WTF

LOL I have a 1/4 drive one that worked for that being a normal Torx, these Torx+ bullshit things are a joke :)

The External Bellhousing bolts on the V6 are Torx head but an 11mm 12 point worked for them..

Seems a bit strange using torx on the bellhousing, even stranger using torx +
I'm guessing you'll be replacing them with hex bolts.

If I've got the tooling here I'll leave em in place, it's only a PITA because I've never had a reason to use/buy Torx+ drivers, have a few normal Torx sets of course...(and bellhousing swaps shouldn't be a service item)

When I built the Toyota Trans adaptor I used cap screws as there wasn't enough room for hex heads/sockets.

Did a bit of research on Trans rebuild kits/upgrade parts for the 4L60e, tons available just have to make a shopping list one day and place an order in the States, makes a nice change dealing 1:1 on the $, MUCH better than 56c!

Guess I'll make a start on labelling wiring and connectors tomorrow and get ready to pull the dash, might also see if I can hunt up a better dash for this thing as the Cross6 one is very basic.

Yes, plenty of 3 window dashes out there, just make sure it is the same vintage as your existing dash as the VZ ones aren't backwards compatible (fuel gauge reads backwards I thonk).. plenty of info on here about the VY/VZ dash upgrades.

The guy I bought the E38 PCM from seems to think the existing dash is going to have the fuel gauge calibration issue with the PCM swap.....

Not sure if that signifies the Tonner got the early style firmware or not
(supplied him with my VIN so he could check)

Adventra has the 3 window and it's just nicer all round, I'd like the better climate control as well but it's not a show stopper.

Today!
Started pulling the Dash out of the Tonner and found it's easier to gutt the interior as well so the Seats and Console came out, next issue was how to get the Radio and Airbag out....

Quick search online and it was all revealed, after lunch I'll go back out and start labelling everything then pull the Dash out and see about running the new Loom into the engine bay...

Recently done a similar three window swap with a HSV unit on my Tonner. You will need to have the new cluster cal'd with the correct part no to suit your Tonner's fuel tank. Make sure your new cluster is as close to the build date as your vehicle. EG series 1 & series 2 are different.
Clusters do have year & month on reverse side adjacent the connector.
If you need the Cal part no I should have it here somewhere.

Thanks for that!

Any info that helps would be great!
(I came across your thread this morning while I was searching)

Side note: Looks like the Brickie that owned it before me managed to break the rear screen... I'll clean it up properly now the interiors out, broken glass and sand everywhere.

Ok the fella who cal'd mine got two part no's
1. 92174078 = Cab Chassis

2. 92174079 = utility

For some reason this guy used the Ute cal & appears to be ok, I thought the Cab Chassis would have been the correct one though? let me know if you'd like a copy of the tech sheet probably email it to you?
Would appreciate down the track if you could let me know what one you ended up using?

Cheers

No probs at all!

PM'd my e-mail addy and yes I'll let you know for sure!

Just have to track down a Cluster now, getting a price on a new one from my Holden guy but I'm guessing a bit exe.

Today End!

Got a bit done, need some ferrets to work out what else holds this Dash in, debadged the car then pulled the washer bottle out so I could clean it's screen, used to have to flick the steering side to side to get it to flow... NFI what the layer was on it.

Today!
Ok Loom and Dash are out, ended up having to cut the old Loom :(

I'll DePin the Engine bay Fuse box on the new Loom and feed it through, Holden must thread the Loom through the hole in the Fireway before Bonding it into the shell as there's no way possible to get the Fuse panel and Horseshoe through the hole with the Strut Tower in the way!

I'm finding a few differences in the Looms already, I bought one for a VZ CrossTrac Crewman thinking it would be damn close..
(i.e. No glovebox illumination wiring at all, no biggie I can splice that in, more of a concern is no connector for what looks like a G Sensor mounted in the middle of my car on the trans tunnel.

I'll confirm that's what it is then trace the old loom and find out what it connects to.... ****it if I'd known it was going to be this much of a PITA I wouldn't have gone ahead but I'm too far into it now to turn back...

Keep at it brother! As a convert to the Cross-Trac system you are getting the full thumbs up from me! Perhaps you can fit a 6L into my V6 Addy next! haha!

Loom comes out as one. No need to cut it... How so you think they change out a faulty loom. You just need to pull loom out of horse shoe then remove fuses relays from holder and pass it through. Have changed 20 or so that way


There will also be a fair few other differences in the looms being ones a v8 and other is a 6

but i must say will be good to see when its all up and going :goodjob:

I pulled the Horseshoe off and all the fuses and relays, are you sure it will come out?
(Also stripped out the Brake Master and Booster)

Just waiting on a call back from my Holden guy on the Loom, seems like Holden build each loom to suit whatever spec the car is.... (used to be more universal i.e. a V8 Loom had ALL of the connectors/wires in place)

Yep v6 Loom is totally different but things like a glovebox light I'd have expected to be standard across the range...

The Sensor looks to be a Yaw Sensor, if needs be I can trace it back and rob the plug and wires from the old harness.

yep positive....

also prob a steering angle sensor near the column?

yeh they build them all specific... they do it now to save money.. only fit what needs to be there ....

worked at Holden for over 10 years... its how we used to do it. :)

Went back out and tried it with the Old Fuse box and still couldn't get it to go back into the Cabin, found "Mr Goop" at Holden had gone a bit nuts with the seam sealer and heat shield so trimmed that all back then tried it from the Cabin side as if I were installing...

DAMN tight but went through, isn't going to be nice on a brand new harness so I think I'll "bend" the opening a touch to make it easier then knock it back into place once done ;)

Didn't spot an SAS while I was pulling it apart today, I'll look again in the morning.

Traced the Yaw sensor wires, they go into the ABS Pump so I ferreted them out of the old loom,bit curious about the glovebox light and switch though...

found it :)... actually the diagrams and manual are really confusing...

will be very interesting if this ESP works on the 8...

manual shows only v6's with ESP but the diagrams are a little different

Thinking about this, doe the BCM run the ESP or is that a PCM function?
(If the code for the V8 isn't there or even an option I'd be wasting my time running the Sensor wires)

Have TIS2WEB access. ;). So have all manuals effectively.
