    13/04/1300 Mazda 626 Turbo

    Yep. Nah.

    Haven't read the rules yet. Have now.

    Didn't plan on winning the auction for this. Went $85 over my limit, so yes I did.

    Wouldn't have a clue how to modify it. Getting there.

    Have $814.99 to spend on it. Have $18.5 to spend on it.

    Have more responsible things I should be doing with my money. nothing better to do with my money

    Have more responsible things I should be doing with my time. nothing better to do with my time

    Won't get anything back for it.

    Better run a fucking 13.999sec quarter by the time it's done.

    Fuck you PF and your stuipd challenges! awesome challenges!







    Apparently: starts & runs, 1 owner since new, 264k kms & recently de-registered.
    Hopefully I get to pick it up this weekend. Hopefully it is in bad enough condition that I don't feel guilty ripping it to bits.

    Preliminary plan:

    car---------------------------------------------------------------------- 485
    larger intercooler---------------------------------------------------- 50
    upgraded intercooler plumbing, silicon & hose clamps------- 50
    3" dump pipe w/ bypass to atmosphere------------------------ 50
    larger turbo----------------------------------------------------------- 100
    misc. turbo fittings--------------------------------------------------- 50
    fuel controller--------------------------------------------------------- 70
    injectors or adjustable FPR---------------------------------------- 80
    larger fuel pump----------------------------------------------------- 80
    clutch------------------------------------------------------------------- 200
    total-------------------------------------------------------- 1215

    If I'm smart I'll do the mods in stages and combined with hopefully 100kg weight reduction maybe not all mods will be required (highly doubt it).

    i have an assuming larger than standard intercooler you can take with all associated piping (not that it will be any use but i dont want the shit) for free...

    its factory jzz30 soarer gear to give you a reference size... side mount gayness but might suit in some way shape or form to turn into a top mount... who knows... you have a welder and cutting diskst to make it into what you want and its free...

    sweet, should be a good one. take every single thing out of it. keep the driver's seat only. should drop a fair bit of weight.

    yeah man! i'll take it. pls pm me some pick up details and your favourite beer/spirit and i'll give you a 6 pack for it if that isn't too stingy.

    i'm assuming it has aluminium (not plastic) end tanks?

    no need for anything for it... free is free...

    i think it has alloy end tanks but tbh i havent looked at it for years and its been in a box in my shed doing nothing... looked to be reasonable condition though lol

    finally she's in my shed!



    this too!



    some features:
    the sunroof that never seals


    adjustable suspension


    mother flipping ants


    got to get a road worthy before i can get too crazy, but i will try and do as much weight reduction that i think i can get away with before then

    steel upper radiator support brackets swapped out with aluminium ones (weight saving 0.2g)


    cruise control unit removed


    unwanted crap removed from accelerator pedal
    before

    after


    'the pile'. once it starts getting large i'll start weighing it. i'm hoping for 100kg to be removed witout a copper knowing what's going on if he/she has a sticky beak


    took her for a lap around my back yard and it's no rocket ship but it goes alright. i think it weighs about 1300kg and has about 100 flywheel kws - not really much power to weight by todays standards, even for a naturally aspirated car.

    isn't first gear very much traction limited anyway? (i guess not at the strip with proper tyres.) what about 2nd gear onwards, pull much harder?

    edit: forgot about the mx6 thread

I had a s4 turbo on mine first, bad combo, but for drags might be ok, it would only manage 2 psi in first then 6 in 2nd then boost cut at 8 in 3rd

    Good start, pity you can't easily weigh the ants. That sunroof might be a blessing is disguise. Replace with fixed polyarbonate?

    i want to do something a bit more elegant than a flat sheet of aluminium and 50 rivets. poly will still need to be lapped over the existing roof and riveted down? would be good to come up with something that can be held down from the underside to keep the roof line flush.

    Maybe use the same thickness poly as the existing glass so you can reuse the rubbers. Then delete the mechanism and seal with silicon.

    moar (weight reduction) progress

    rear seat retaining brackets trimmed
    from

    to


    1 of XXX ants nests found and destroyed


    some dodgyness - indicator glued to headlight. i'll have to track another indicator down.


    speed holes added to headlight mounting brackets


    fuel filler pipe with air-fuel separator chamber thingy attached

    fuel filler pipe with air-fuel separator chamber thingy deleted


    trimmed & holesawed front bumper mounts

    trimmed rear bumper mounts (speed holes from factory)

    trimmings from front & rear bumper mounts


    'the pile' has grown. i haven't weighed it yet but i suspect it is close to 50kg. won't do much more weight reduction until after a road worthy in a week's time. better move the pile out of site before the road worthy, else i've got some 'splaining to do lol.



    to be honest i'm really happy with the condition of the car for the age and price. doesn't look like it has ever been in a prang. there is a little rust in the boot floor due to previous owner being too lazy to unblock the boot drain pipes. has new exhaust, struts have been replaced before (haven't tested them with the car lowered yet), plenty of tyre left, plenty of brake pad left, engine pretty dirty but no major leaks, steering and cv boots intact, etc.

    problems are the front driver-side indicator, front driver-side power window, sunroof machanism and boot rust. another issue to sort out before the road worthy will be a belt tensioner for the power steering belt now that the a/c compressor has been removed. i can see that job being a pain in the arse with the engine still in the car.

    Could you use the existing a/c pulley and mounting points for max cheapness?

    Yeah, will do that for the road worthy and up until the engine has to come out for the first time (for whatever reason, most likely the clutch). Once out it should be easy to fab up. The a/c comp, its bulky cast iron mounting bracket and its adjustment mechanism all add up to a bit of weight.

    Really confused as to whether to keep this road legalish or stripped 'beyond reasonable repair'. I'm talking about weight reduction (like gutting doors) that would present a serious occupant safety hazard if i was to sell the car to someone else and they were to be involved in a crash. There is an option of selling the car excessively stripped with 'car not for road use' blah blah blah written on the receipt. It would be good to see some young ricer benefit from what will end up being +100 plus hrs labour and hopefully a pretty quick car, rather than just scrapping it once the challenge is finished. meh /csh

    Picked up standalone engine managment and the majority of a very well used S14 3" cat back exhaust last night for cheap. These items will be stored for a later date incase the vane air flow meter starts giving me the shits.

    I hope my exhaust will help you out. I look forward to seeing this finished, after reading your other build threads I somehow don't see this stopping even after you got it down to a 13 subscribed for awesomeness

    spent a cool 26hrs straight the weekend before last getting this thing into road worthy condition. tonnes of stuff needed doing. a sample of some stuff is below.

    all struts got bumpstops consisting of old commodore control arm bushes with steel sleeve pressed out and rubber cut in half


    lots and lots of time wasted trying to get all power steering windows and switches working. in the end it was a success. the pic below is me trying to swap rear passenger motor for front driver motor (anticipating road worthy inspector is most likely to actuate front driver window). motors ended up being different so swap was not possible. ended up soldering new bushes onto the driver motor to get it working again.


    broken part of front driver seat raise/lower mechanism. 40min diassemble, 30sec weld, 20min reassemble. fuck.


    12mths of leaving car outdoors with sunroof partially open (which drained into the RHS boot well) = rusted RHS boot well



    the only real cost of getting the car to road worthy condition - a $20 passenger outer CV boot. well over 1000Nm required to loosen the hub nut!!!




    ok, so fast forward a week. i got the car roadworthied - first go with a legit inspector. got my paperwork together and drove the car to QLD transport for rego. the car broke down on the way! checked fuel, spark, EFI circuit power, throttle body, etc. couldn't figure it out. called RACQ and after a hell of a lot of to-and-fro they agreed to provide roadside assistance for my unregistered car. problem ended up being a sticking secondary throttle butterfly (haven't figured out what it is for yet).

    ok, so with car not registered i'm afraid to do too much to it incase QLD transport want to inspect it as part of the registration process. nevertheless i have done some stuff.

    new plastic wheel well cover panels. a lot smaller than the ones they replaced. not for weight saving but to make the car easier to disassemble/reassemble.



    hatch gutted (3rd pic is all the stuff i managed to remove). unfortunately nowhere near the weight saving i had hoped. those circles were cut out with a fucken angle grinder cause i'm too pov to buy a big high speed steel holesaw





    turbo manifold flange made out of towball steel






    rear seat belts now mounted to rear seats via 1 x 6mm bolt instead of mounted to the floor via 2 x 12mm bolts (lol). did it this way for far easier removal/reinstallation at the drag strip.






    pic of the car with the new hatch prop. i like it!
