Operation SOA 75

[Z()LTAN]

yeah? whys that?

ive seen lifted springs flex super fine... and on a lux too

i understand if you get heavy spings they dont flex well, but they dont have to be heavy, i can afford some droop and go medium.

I have a set of stock parabolics, but they are super sagged... Could try to reset them and give them a go too

I believe that a lifted sping is just a longer spring thats been set at a higher arc and still gives same eye - eye distance...

so a lifted is the same as a stock but longer and higher?

ehh

[crushers]

i want you to think this through, which will flex better?
a flat spring with no arch or a spring with arch fighting the upwards movement?i old go with the parabolics for perfleax...
cheers

Don't be offended but I think you have it backwards, Myself I would decide how much lift I need/want and build accordingly ?

[matt 105]

wheres you sence of humour?????

Problem is, i haven't lifted like this before, and don't know what its going to do.

I know how i want to lift it, and thats what im going to do, how it turns out, is how its gonna be.

Now back to the car
Question

Is it possible to reset parabolic springs?

I have the engine, (pix lata)
New 1HZ out of an 06 100 series.

Now do i need the complete wiring harness or do i only need the harness downstream from the computer?

Will the 75 series harness work?

Do i need the computer from the 100s or from a 79s with the same engine!?

So many questions!

The springs will be the make or break issue in the SOA. I would forget the notion of using reset worn out springs.
I would see Dean at Malaga Suspension or maybe West Coast Springs in Ashfield and get some purpose built springs suitable for SOA.

I think the high arched springs look crap and for the reasons Crushers outlined will not flex too well.SEE BELOW(not too bad but could be a little lower,I think its in Darwin)
The SOA with flattish springs will still have a good sized lift .
I would leave the double hinged shackles alone until the SOA is complete and fully test driven

You do know the cops will put a SOA vehicle off the road as soon as they see it?

The computer doesnt do much if anything on the 1HZ as far as I know.

The cruisers with the 1HD FTE do have some(LOTS) electronics.
For your purposes I would study the electrical schematic in the FSM and get the engine set up like a early 90s 1HZ with just one wire to the fuel cut solenoid.

[Z()LTAN]

Money is a bit tight, as im only an apprentice, so custom springs were more or less out of the question, but i will inquire about them, as work deals with west coast springs fairly often.

i will be running all stock suspension after the SOA to make sure all is well then moding yet again.

Im not rlly worried about cops, as i can get it certified, but if it gets yellowed its ok with me

So all the electric governors are only for fuel shutoff and fuel compensation? and not injection in any kind?

Do i need a computer at all?

Tanx for the speedy reply!

mate who gave u the false impression that you can get a soa certified?

[Z()LTAN]

point me out where it says "NO SOA ON ANY VEHICLE ALLOWED" in the regulations... and ill listen to you..

Having a mate who is soon to be an mechanical engineer is great!

yes.. kon... im talking about you.... i have a favor to ask when your out of your time...

But you prolly already know this rofl

spring over give what between6-7" lift, 2" lift in total is the regs for w.a un engineered and even with engineering lane change tests the max is like 150mm, so with the spring over your right on the max lift then what size tyres are u planning on running?

Yes Zoltan 50 mm is the max. Now the cops are fairly lenient on this and many get away with 100 mm but I think your lift will be like kicking a rottweiller in the balls when the cops see it

Some say it is still theoretically possible to have a SOA but with strict engineering supervision,eg by increasing the width of the axles to suit the height $$$
The engineering supervision is ongoing during the lift meaning stages of inspections
I would consult someone 1st to see what it entails before you start the mods.
Im sure WC springs could give you some advice as they get updates from the traffic branch

I think it may also look at the coolant temp for the glow plug system.
If it has an immobilser it will be connected to the computer.
The tacho may also go through the computer.
Also the aircon fast idle as it replaced the vacuum system.

Not sure about the fuel compensation,do you mean the HAC?

If you have a suitable earlier type inj pump, use that.
If the glow system is different ,use a manual type.

When I did my swap I went into car yards and looked at 1HZ engines and compared the years. There is not much differnce

[Z()LTAN]

Its been a a month or so, and ive done a few things.

I got the engine, straight bolt in little wiring needed
06 model 1HZ with 5k kms on the clock




Started to strip and clean the machine, ive taken the tray off for access to cleaning and modding the chassis, the body will come off also





Got the 95 model cruser up and running, perfect and some cheapie tires to make it look the part

[Z()LTAN]

[beaufort-fj60]

looking good

[crushers]

damn, i got me a set of those turbine rims and have wondered how they would look on a truck...i like it...a lot

[Tapage]

This HZ come from a auto tranny Cruiser .. ?

[Z()LTAN]

nope, manual 105 series

The denso module ( black one with the blue letters ) looks like my 1HD-T with A442 have over the Injection pump ..

[Z()LTAN]

what do you meen by that? they use the same injector pumps dont they?

[roscoFJ73]

I love a HZJ75 and 1HZ build up thread That body and chassis is looking extremely rust free and is a great start.
Zoltan ,do you have any good 750x16 tyres for sale and any 1HZ parts?
Im after a flywheel and the plate that goes between a gearbox and engine or maybe a complete dead engine if the crank is good

NAH and the 1hd ft and 1hd fte are different again.

[Z()LTAN]

i have a 1hz block minus head spare, but im giving that to a friend, still dont know if he wants it though... Adam if you read this. Let me know

[Kon]

HELL YES!!!
please!!! I beg you!!!
i will pay cash and/or jacks and/or my valuable time!!

my ute will be ready to take over the pits by the end of this weekend, so i'll have a car to drive.. you should hear it without the muffler! hehehe, so loud!
it'll be weird driving a fourby with power!

four cylinders just doesn't cut it!
i swear its losing power by the day!! dont get me wrong, i love my BJ60! for city driving its awesome, relaxing and economical! taking it offroad is almost embarrasing.


glad to see ya got the 95 running...
atleast now you've got a fourby!! taken it out for a drive yet?

[Kon]

btw what other parts is it missing? a mate from uni has a bunch of parts leftover from his projects. starter, alternator etc...

this is a list of his Toyotas alone:
HZJ80 with 6.5chev diesel
HDJ80 with factory lockers
BJ70 with a 1HZ
+ a 3B and a partial 1HZ

so he has too many toys!

naaaahhh just making apointment to the denso module .. I was thinking it only comes with Auto trannys ..
