How did I miss this thread??
Great read so far, great job you are doing, watching this keenly.
Take heaps of pics.
Love your workshop, well setup for projects like this.

Thanks Cashie,

My projects have a way of getting out of control.....

This time I'm trying to NOT get carried away and stick to a bolton approach for most of it, ultimate goal is to build something that will be eligble for tarmac rallies/track days.

Dropping it down should result in a nice low CoG add some decent suspension and brakes then possibly some more power and it should be a fun toy.

I ran the L98 with a T04z in the Jap car for a total of 700 Km's before a suspension arm failed and killed it so I've seen this engines potential and the CrossTrac will mean it has a chance of hooking up.

I love the workshop it was the selling point for this property, been here 6 months now and am slowly getting things set up as I want it, I have to build a Mezzanine for storage and in 12 months will reassess the need/desire for a dyno.

Are there any issues lowering these, I always thought they had to sit high for the AWD setup?
The L98 is certainly an excellent engine, pretty underrated by those outside the Holden owners circles.
Your own dyno, holly sh1t, where will this all end, you could set up a LSx tuning business on the side.
Have you got any links for any of your other projects?

I asked the question awhile back without much success but I "believe" you can drop them a good deal before there are issues, the rear will get either a Wagon IRS or one out of an Adventra just depends on the final wheel/tire combo I choose.

I spent a decade or so playing with Turbo I-6's and managed to get 410rwkw out of the 3.0L at the end but then decided on a change of direction with the L98.

Been in contact with both Mainline and DynoDynamics and have the $$$ set aside, there are a few environmental issues to address here, I have an engineer mate helping suss all that out but I still have 6 months before I go/no go on it.

Not really looking to run the dyno as a business it's more for my own use as I'm a constant "fiddler", the I-6 logged 16+ hours of Dyno time and untold hours of road tuning before I was "happy"

I don't really post the other projects due to some of the local legislation, that's part of the appeal of the CrossTrac project it's actually going to be legit for a change.

jacking them up is where most problems occur throwing off the geometry for the drive shafts etc

i wonder how the transmission would cope with 32" muddies on (thats if you could fit them)

starting to hate this thread, the more i read the more i want to throw into mine when it arrives haha .. hopefully it doesnt get to the point like my SS and throwing 15k at it

LOL my last project had 25k of engine management in it

Trying very HARD not to lose the plot this time ......

I bought a Quick Silver VYII

I cant find it anywhere but was there an update between VY-VYII, I read that maybe they swapped to electronic throttle body? i had a look under the hood but the throttle body looked much the same as my L98 except maybe a little bigger (didn't notice any throttle cables). tell you the truth i just expected it to have a cable throttle.

Under the hood it looked much the same as what AllWheelSlide posted with the VZ.

Does that mean its 250kw or 235kw?

Sorry to go off topic but the VYII had 235kw, the VZ 2005 model released around april had the 250kw..

Don't sweat it at all it's not really OT, my threads do that from time to time but always end up more or less back on track!

What year/month was the VYII and what changes were made?

[IJ.]

Today!
Made a start on the tear down, going slowly as I don't have a manual for this car and really don't want to damage/destroy parts removing them!

Here's a good illustration why a PWR "works" just the sheer mass of extra aluminium would be it over the stock VZ Rad.

Done enough for today just heading into town to pick up a Rad cap.

[cashie]

Looking good...

Thanks Cashie,

They didn't want the Transfer case to fall out it's bolted in 3>4 places then has an additional Steel cross member bolted in as well....

I'll see if I can make some more headway tomorrow.

[IJ.]

Today!
Got as much done as I could then had to do a run into Town to buy a GM Fuel line tool as I don't have one, of course being in the Bush they stiffed me for what is just 2 pieces of plastic with a rivet in the middle but the alternative was to burn $50 of fuel and go buy it from one of my suppliers.....

I'm ready to drop the engine, trans and front subframe, CBF'd today so will attack it in the morning.

On the way back from town I stopped in at the post office and collected my box of bits from the USA .

[cashie]

Stop teasing, what's in the box?
Get lots of pics of the engine out job..

LOL sorry no tease, just some small parts I was missing/had modded for the last project that I couldn't get from Holden.

Coil looms, Air bleed crossover pipe between the heads and some 45 degree MSD boots so I can shorten the Plug leads I made to put the coils back on the rocker covers

Rgr on the many pics when I drop the engine, about the hardest part of this project will be pulling the dash to replace the entire main loom, I laid it out on the floor today to check some connectors and it's a LOT of wire!

I stupidly decided to totally rewire the last project and after putting 850 metres of Tefzal Milspec wire into it with a couple of 100 connectors I'm thinking this "should" be a little easier.....
