    More to come with a proper writeup in due course. Soon the next steps will be a little slower, but after that will have all the juicy details! Aiming to have this finished in 3-4 weeks, rolling in 2.

    Let the Riddle of Steel begin!

    Looks good. Is that an FD bumper in the background?

    Bingo! Shop owner has a rotary habit.. There are four in the shop at the moment. Last week was five FDs and an RX8, with the S2k wedged between them, a 2JZ swapped brown cressida wagon and a 1UZ mk4 box supra! Quite the mongrel mix. A workmate had one of those ls400 sourced 1uzs in a mk4 back in 07, custom headers with a few other tricks, it flew! And Must say the RX8s look tight in white. Not a fan of them but it's a rare colour and actually looked really good, shows off the subtle lines best.

    Ended up modifying the oem trans brace with offset brackets, as we can't get the engine quite as far back as your swap, RHD cars have a bigger bulkhead on the clutch/master cyl or driver side here Ending up with a similar mounting position to the import muscle setup, little bit closer in though. Also exhaust clearance is going to get interesting with the header design we need, can't use off shelf unfortunately and the stock brace allows easier routing of midpipes. But the engine mounts are doing well, thanks dude! Only change is we have to add a small brace in middle of box section to meet NZ regs, they're rather strict over here.

    Soon engine/trans will be mated for good, all the engine cooling/oil/accessories installed then wiring/piping/etc and sending her off for a few weeks to get the exhaust system made.
    Main mechanical parts nearly done though but of course heaps left to do.

    Update, been a long time.

    Surge tank in the 'secret rear compartment' under way.
    Old surge tank design (pictured w/A1000) shown also. Aeromotive A1000 installed for uhh.. futureproofing. If things go well I want look at a 502 RHS build or an LSNEXT block.


    LS3 was nana'd around too much, plus too much oil ingested for the sake of emissions, so it needs a big carbon clean which has been done. Honing was still very good. New valvesprings and pushrods for the custom ground kelford cam fitted too. More in next post

    LS3 cleaned up.

    Brass/kevlar clutch and custom moly FW to be fitted before final alignment, need billet engine mounts first.

    3 Stage Aviaid dry sump is here, just waiting on a different tank size to fit in bumper properly. Thanks to Aviaid for all their help in supporting us for this rather unusual project.

    DSS came through, thank you Xyster - perfect fit.

    In the hole! Fits like a glove.

    Quicktime LS NHRA bellhousing, but not so NHRA after we have to trim the bottom lip off. Should've got the non rated one and saved a few bucks. Found out about them after ordering >__> Won't be running under 10s in a circuit configuration anyway. Mated to T56 mag with an ultimate street quickshifter.

    DSS 600hp shafts all round. Their new process for the axles is very interesting, super awesome steel and process - have a read up on LS1tech.

    Twin row TC kit in.

    As you can see the hone is perfectly fine after 20k miles. Looks new!

    Steering rack extension fabricated, we can't weld it here as our regulations are stricter.

    Have to fab a new chassis brace to re strengthen the frame after removing the stock one still.

    Willwood 6 pots waiting to go on.

    Fuel lines done and remote line for boot battery/inverter setup is done also. Should really help keep weight distribution practically stock. Can't remember what status is with brake lines but they're getting some love too.

    To do list:
    finish fuel system. Plumb oil system, oil/trans coolers, finish electrical. Roll centre need to source that, maybe adjustable A arms.. we'll see. Electric Prius AC system if I can get one working. Fit brake system. Maybe a voltex type 3 if I can find another one (missed one auction due to slack Japanese agent.. ffs).
    Air intake. Build exhaust system (flowmasters yeee boi!), figure out what 17"s to get, likely enkei GTC01. Base tune, Get it legal, road tune and go do some track days then events.

    Probably something I've forgotten. Been a very long w
    eek!
    Aiming to have this finished in January but we'll see...

    So far keeping exterior stock. Full on 'torqueless wonder' sleeper mode not too loud also to keep the game on the down low.. don't want any attention, S2Ks are rare enough in New Zealand, most unknowing people here, think they're a new Audi or Porsche design. Timeless design, thanks to Honda!

    End result: worlds first JDM S2K LS swapped, one of (if not) the first with a full homoglated FIA cage/restraint setup, first non camaro with '15 z/28 helical rear diff and all street legal in New Zealand! Good things take time (much longer than expected) and deepest thank you to everyone here for the inspiration. Getting super excited to get this all finished!

    Had lots of life BS going on but this project is going to be finished one way or another for Summer (winter where most of you are). Literally sitting on the funds to finish it.

    Headers and brakes done.
    Few changes to build as research uncovered easier ways to do things.

    Including a Laminova dual oil to water cooler (same shit Koenigsegg uses 'em so must be okay!).

    Left to do:
    Wiring
    Plumbing (fuel/oil)
    Single resonator with integrated X-pipe between frame rails (16L capacity)
    Dual 3"/800HP design whole way through
    Electric cutouts on top of Super 50s in a custom housing (so the WOF faggots don't see it - even though it's illegal heaps of stock cars have these systems from factory with no problem for some reason..) this will enable discreet cruising and literally a 'volume control' for the car with infinite adjust-ability and critically - no flow/hp difference between open (loud) and quiet operation.
    Considering PMG/BAS for electrical system so can pre-heat the increased oil volume (2gal res) and provide other efficiency advantages.

    Few small top end valve train mods to be done to ensure rock solid reliability on track.
    -Morel Link bar lifters
    -Trunnions - probably go for Straub
    -Rocker bearings
    ECU going from Link G4 xtreme+ black to a link thunder (more I/O + monitoring etc)
    Will be seeing if can get rev matching going and should be no issue running no lift shift as well.
    TC/LC of course all will be accounted for too.
    Line lock
    Custom surge tank to be completed
    Underbracing + in-house ground effects/aero to my design including a large diffuser (want to avoid a wing and keep stock body shape)
    Metal/custom flares to fit 17x10 square RPF1
    Considered EWP but have heard they don't hold up to heat generated from road racing/tracking.

    Going to replace EPS as it has a slight whack on it from prior owner/crashing. Safe than sorry and it's not hard to get at now.
    Few misc things like new harnesses needed as they have expired/dated.
    Also looking at ways to lower the buckets another inch or so and retain adjustable setting. Tricky.

    Seems like a lot but it will get chewed through quick once final quotes are in place as shop has more people on board now It is a good way to show off what can be done to customers though, so they're not in a huge hurry to get rid of it lol, but it can't live there forever.
