    XJ6 - aka purple shitbox, purple people eater, now with more LS1

    Well we've been putting this together for a few weeks now, so time to put up a few pics.

    Starting off with a 1984 XJ6, comes as stock with a straight 6 4.2l. Very old engine design, uses tons of petrol, makes noise, not much poke.

    I've driven the car for a couple of years and it's been fine, nothing major broke, I like it. During this time I've replaced the springs with Kingsprings with a slight drop, Gaz adjsustable shocks, polybushed the front, new discs / pads / hoses.
    Also a carputer to serve up tunes / nav / phone running Centrafuse on a 7" touchscreen in the dash.

    Car was working well, but was woefully underpowered.

    I can pretty much blame Gianttomato for the next bit, we were working together a while back and he kept encouraging me to drop in the LS1. Has he been abducted by aliens?

    Here's the unmolested rig.

    With the enormous + heavy 8 valve DOHC engine.



    And the screen if you're interested.



    I got a swap kit consisting of engine + trans mounts, speedo and tacho converters, water + oil senders here

    Had that lot shipped to Vegas when I was there for a "conference" so saved tons on shipping. Brought it all back in my luggage, which Qantas lost but saved me the agro of going through customs with it. Came the next day by courier which was fine.

    The engine mounts line up great, but had to do a fair bit of adjusting for the trans mounts which were miles off.

    Anyway - much thanks to dogsballs and stocky who came round last month for the transplant weekend - great work lads.

    Jag motor came out fairly easily.

    And the LS1 fits great! It's I think a stock VU motor but who knows as the dodgy ebay twat that sold it me has gone off radar now. I do know it had clean oil, auto fluid was clear, it starts easily but won't run till I get the VATS off. Bit noisy with no exhaust, bare manifolds!



    Now just doing lots of fucking about with hoses / electrics / fiddly bits but should be good to start up this weekend.
    I'm using a VX radiator with the Jag header tank in stock position, trying to keep to as many standard parts as possible.


    I'll tidy up the wires and get more photos soon.

    Awesome.
    The Jag XJ6 is perhaps the best 4 door design ever.

    Nice. Looks like a neat car to start with too.

    I've been working on one with a 1UZ in it for a month or so. It's a bit of a dog but I am ashamed to admit that they are actually quite a well engineered car. Even the wiring is quite good.
    Best thing about them is the engine bay can swallow any engine, it's huge. A 1UZ looks lonely in there.

    I want an XJC(not XJS). Hotness.

    Dropped a few valves had it?

    got me.

    It's such a wide engine though, with a seperate inlet + exhaust cam, the V8 is about as wide. DOHC, two valves per cylinder.

    It's pretty squeezy for the manifolds though.

    I'm using a pair of right hand side 2006 Corvette cast iron manifolds - this gives enough room around the steering column where the exit has to go forwards from the flange. All the commodore exhausts head back - would hit the rack.
    I've changed the sump to a Camaro one, rear hump, with a new pickup, a few chops to the baffle. Sump needed a small nip to clear the rack still.

    shit man, i've just realised my 10mm 1/4 inch drive socket is missing from my set - last time I saw it was when i was working on the sump - I hope it's not stuck in there! Guess we'll find out when you fire it up hey?

    this is something I've wanted to do for a long while! I've always wanted one of these jags, but also knew they have shit heavy engines. LS1 makes a lot of sense in a jag!

    Fixed.

    Also, love this car. Seriously, I reckon anything with a big enough engine bay and RWD is an excellent candidate for an LSx swap.

    I was sitting behind one of these last night at the lights, the 2 old blokes were loving it but I came to the conclusion that it needed more fasts and seems you have the right idea.

    Ps, those beers on the car are well juxtaposed.

    Beer is microbrewery -> kegs -> keg fridge -> the glass.

    No bottles - take out the middleman.

    No preservatives either - it's a medical marvel, no hangovers.

    Talking of open pipes, I'll need to do something to make that a bit more legal.

    Currently have the Corvette manifolds on - very tight to the chassis rail but I'm assured they will be ok. They end up as 2.5" with a two hole flange. There's also a port for an oxy sensor in them, which I'll get a plugged.

    This is the left side from above, it's the tightest.



    This is left from below



    And right from below




    I have the downpipes (2.25") and cats from the VU, I was going to try and weld up a system myself but think getting someone else to do all that hard work would be a better option.
    So thinking 2.25" / 2.5" twin system, with a crossover H or X, muffler then a resonator each side, exit through the standard orifices.

    This is going to be my daily, but I'd like it to sound a bit rumbly too.

    What do you think? 2.5 or 2.25?

    If its worth doing, its worth overdoing, so 2.5".

    Mate and I did a replacement 2nd hand 4.2 into a series 3 XJ for a bloke several years ago. Think the replacement engine may have been a bit of a cut above the normal, because there is no way I'd describe that car as slow. NFI what the original donk was like as we had nothing to do with it until old mate cooked it.

    Looks like a good un anyway drscrote.

    ps does your username indicate that you primarily do vasectomies?

    there is a bigger gap than those pics show. i was checking out how much it moved when i revved it and nothing, especially with that flat engine mount.

    twin 2.5" with kiss (on left), open up stock cats.

    yeah your mounts will mean jack shit torque roll of the engine, shouldn't move much at all, i'd be surprised if the thing tags the rail there at all. even if it does we can probably just use the persuasion stick to gently alter the rail a bit

    2.5 inch will be easier for the bloke to source the bends and shit for. if its too noisy, a pair of varex mufflers will help
