    6.0ltr into VK Calais


    Thought I would do a write up of what I have encountered and also what costs I have outlaid to get the 6.0 into my vk Calais 333 pack

    This will be in no particular order and I will try to explain current setup as it will be different as most cars are of this age

    I am not a mechanic, I don’t claim to have done everything or anything ‘right’ this is just what I have done and found through this process.

    I am also an English major or completed a decent level of education so this is written like a child with poor lay out


    As with all conversions there are quite a few unseen things to be done and purchased (as expected) but the do add up, I have searched the forums and not found a current price costing so this is a current price out lay


    there is some work that needed to be completed that I did not find out in my research but once again could be different between car to car but if you get one tip out of spending the time reading through this mess it will prob be worth it


    I have compared products and shopped around and checked reviews, lots of opinions out there including this one but this is my view


    I will itemise as best I can with links if (If can get them, they may not be current by the time you read this thread but you should be able to locate them or similar from description)

    This should be a close representation of cost to my project and I am sure I may forget a couple of things but will do my best



    Starting point (things that are applicable)

    VK Calais 333 pack

    V8 auto as stated in the 333pack

    TH350( keeping in this conversion atm)

    Vk v8 diff with 3.9s

    Fuel lines ect located in standard location

    Ally drop tank with 3 -8an welded in lugs


    Use of this car will be a daily driver and not a show car so hidden wiring and super clean is not the direction


    Second hand / used Parts required


    Wreckers

    I did consider donor car but could not find suitable one with correct trans (4L60e) combined with low k engine these are the best fit in the autos

    6.0ltr 119000kms complete all accessories including cats / o2 sensors , air box, wiring harness, ecm , pedal, pedal controller, a/c comp, power steering ect. $4000


    Side note the a/c apparently does not work with older style set up as they are setup for variable 9but someone might explain or correct me here) also the a/c compressor will not work in current location needs to be removed so when you drop engine in it will clear the rails – high mount single wire operation is what I will be going with there are few kits avail like this one

    https://www.rodshop.com.au/ls1-ls2-ls3-high-mount-air-conditioner-kit.html


    bit ugly on top of the motor will be interested to know if anyone has found and set up a tighter low mount one


    Ls1 sump $150


    Vl power rack and intermediate shaft $100


    Vn K frame $150 – used all the vk gear on this bolts straight in – good idea to check all balls, bushes, rubbers, boots ect while you are doing this for licencing purposes as well as $$$ factor for your conversion they are quite cheap but can be a prick to change in the home workshop



    CRS rod shop kit

    From what I searched on line and for a complete kit to give a good start to the conversion this is what I used, I also used some of their other adaptors ect even though more expensive than other out there once postage was combined worked out cheaper


    $2245

    https://www.rodshop.com.au/holden/v...o-commodore-with-turbo-type-transmission.html



    $25

    https://www.rodshop.com.au/ls1-ls2-ls3-water-temp-sender-adaptor.html


    $39.50

    https://www.rodshop.com.au/ls1-ls2-ls3-and-up-oil-pressure-sender-adaptor.html



    wiring harness needs to be modified I used these guys

    https://www.ultimateconversionwiring.com.au/


    $1500 dependant on what you want him to do of course, very knowledgeable guy – this also included speed sensor similar to below

    – believe it is or the same as the Dakota digital

    Please check your application as this may not be the exact one for you

    https://www.google.com.au/aclk?sa=l...ahUKEwjB95m3xdHhAhXJZVAKHUGyAWcQwg8IRw&adurl=



    I also require o2 sensor extensions 1000mm for driver and 800 for passenger and a 650 MAF sensor extension as I did not think of getting it extended to the length I required (something to look at before making harness)


    - The harness on the drivers side should wrap around the back of the head and thread through the extractor tube of number 8cyc but due to clearance between extractors and head it would be too tight and cook in there so I have routed it through 6 and 4 cyc extractor tubes with heat glass wrap hence reason for drivers o2 sensor to be 1000mm long due to point of o2 sensor exiting harness if you are creating a clean/ show / tidy look this would have to be overcome (mine is a driver so this is not a concern for me- still a bit ugly though)


    $112

    https://www.ultimateconversionwiring.com.au/



    air intake tube filter ect


    found this link… good info on the tuning side of thins you cant just throw a new air intake on -maf or maf less and expect that the engine will be fine

    https://www.oztrack.com.au/2013-09-27-06-14-12/tuning-ve-vf-hsv-holden


    note… I have moved carbon canister from original location in the vk up under the driver’s side bumper attached to the cassis rail and routed my hoses through existing holes (not factory holes) this was to make room for the filter to mount in this location behind headlight


    90 deg silicone elbow

    Went with areoflow as the silicone legs are a bit longer and needed to clear around the front of the throttle body unit

    $43.48

    ally 4" Inch 15 Degree Aluminium Turbo Intercooler Pipe Piping Tube Tubing L=610mm

    $30

    15 deg kink and 610mm as it needs to make it in to the carbon canister area directly behind light without sitting proud up against bonnet

    K&N UNIVERSAL CHROME STRAIGHT FILTER - 4" (102mm) FLANGE - PART # RF-1007

    $50

    Went with this filter as it has a securing stud on the end so I can make a bracket as needs to be secured for licencing


    https://www.ebay.com.au/itm/K-N-UNIVERSAL-CHROME-STRAIGHT-FILTER-4-102mm-FLANGE-PART-RF-1007/252442420991?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

    $70 total


    -top hose requires the bleed port from front of l98 to be plumbed back in to cooling system so I went to top hose with below fittings

    fuel system

    https://hotrodfuelhose.com/blogs/rad-hot-rod-fuel-hose-stuff/ls-swaps-what-you-need-for-fuel-line




    I went the return style setup so these are the parts I used


    Hard line, I already had ½ hard line feeding the previous engine but run in the standard location, this is an issue due to running so close to the extractors. Also the l98 fuel inlet to the rails is on opposite side so I relocated it to passenger side with new 3/8 hard line


    Flow direction-

    from tank to 10mic filter (already present)

    then 10mic filter to pump,

    then pump to filter/ reg inlet,

    then outlet across inner sill then along the outside of chassis rail hard up in wheel outer guard through same bung that brake lines run into this keeps away from all heat possible.

    The filter/ reg has return which goes back to tank.



    Starting at tank


    10mic filter (already there) 8an fitting

    $0

    I used flex line from pump to filter / reg as I had some left over in kit that I purchased to go from end of hard line to engine to cost cut a bit



    Then another one of these from filter out to hard line


    Then I used AEROFLOW AF109-06BLK 3/8" HARD LINE TO -6AN FEMALEADAPTER BLACK w/ OLIVE x2

    miscellaneous vac hoses and lines

    $50


    Oils and coolant 150


    Exhaust 2.5

    Quote 2000


    Note from same link as above to the air intake system


    If you change your exhaust the rear 02 sensors monitor activity for evidence of catalytic converter failure and will also throw engine lights due to error codes. These error codes are adjusted when the engine is tuned.


    Power steer lines & trans extensions

    (trans cooler lines required extension due to how tight the extractors are between the rail and engine and I did not want to go over the top of engine


    As for the power steer lines I routed these from rack to drivers side of sump then around sump at the front secured by p clamps the around oil filter the straight up behind pump unit I put some hose after the first bend from the rack to account for the movement in the engine while running

    $500


    Engineering report

    $1900


    Pit inspection 140 ( as I want it licenced with engine)




    So the total has been $13.372 atm with all work completed by myself, as I said before I not quite finished yet (as of today) but all work quoted or estimated


    Only things to do are full Exhaust (still included price in the total) - I have just cut and shut my current setup but will require cats to be engineered…Engineering report, pits



    Power steering rack clearance issues – none providing the steering rack mounts are in original position, holes can be elongated slightly if needed extra clearance – most likely over to the pass side (rod shop try y stainless steel extractors)



    power steering lines need to be made up from local hose service most have a mobile service that will come to you, if not you can take old lines down to hose doctor alike with a bent up piece of brake hard line bent how you require it and get them to make it up for you


    Something to think about is the location of you trans lines and where they run. Mine were running between rail and extractors on the driver’s side, I do not like this as the extractors are tight in that area so if yours are the same you may need to reroute them as I have done


    Another line that needs to be rerouted is the fuel line to the canister as standard location will rub in between extractors and rail, I just bent mine further up and come across the rail instead of down beside


    Also with the trans and the rod shop extractors , the extractors require a fair chunk trimmed off of the outer side of the TH350 this is the area that looks like wings on the outer edge where the torque converter dust cover mount flush up too. I took 10mm off of the drivers and even more off of the passengers so the extractors bolt up flush on the engine. Best move here is to trial fit extractors to motor before dropping engine in


    I would also recommend removing the coil pack closest to the driver as the clearance is too tight with pass extractor laid in position see step below


    I think the rod shop instructions say leave the engine mount plates loose on the block until fitted be aware they are pricks to tighten the bolts on the pass side (the central location for this plate was perfect for my install) so up to you


    Also ensure that you steering intermediate shafts has been swapped


    When I did drop engine in i had trans mated to engine


    Drop engine ¾ way in the loosely fit passenger extractor


    Drivers extractor is 3 piece set up so can be fitted after the engine is seated


    Leave power rack out or hanging loose


    Don’t tighten up drivers side extractor until you have fitted power rack checked clearances and bolted to intermediate shaft and had you hoses made and fitted to power rack then you can slide on rear slip on section and tighten extractors


    also it would be smart to fit he trans mount while out of vehicle as the bolts are in a poor spot to tighten up this will also give you the chance to check if your trans sump clears drivers extractor mine needed massage to get clearance as it was just fouling


    as for the electronic pedal setup, you will need to remove the original bracket to mount this cleanly this is one of the last jobs I have to do this week along with plugging in the wiring extensions that I am waiting to receive then start up will occur….i hope.


    I hope this write up although all over the place helps at least someone out there get to what they are trying to achieve with a little more clarity or maybe this has just confuse the situation.



    Cheers

    Do you have it up and running and what's it like to drive? Have you weighed the car yet?
    Thanks Keith
