jzz30 halfcut to convert MA70 to JZA70 (feggin peed off)
|

So after 5-6 brutal months of wating for my jza70 halfcut to arrive. It finally arrives today!! but @#$$ it's a jzz30 soarer halfcut!!
So this conversion suddenly becomes a big pain in the ass.
I know i need a jza70 crossmember to make my MA70 into a JZA70.
What else am i going to need? A jza70/ma70 manual pedal kit? (my ma70 is an auto)
How about steering rack and power steering pump etc?
I have no idea on what i will need for this conversion to work.
I'm hoping somebody knows, or has gone this road aswell. Or if somone is selling the remains of a JZA70 cut minus engine and gearbox.
 dam i should of dealt with another import place.

can't you abuse them? if you ordered a jza70 and got a jzz30 its there fault no? Or you have waited long enough for it all.
but all in all there shouldn't be too much to make it fit, power pump should work fine.

will need a jza70 sump that's for sure. And wiring will no doubt have to be done to connect this soarer to my supra body loom.
Yeah i could abuse them, It's all lost money from here on, as the cost of shipping it around and getting a jza70 cut is gonna be a prick and mean money, or buy all teh parts i need which is also more money and extra time wasted. Dam it has not sunk in how angry i am with this mob, i had rang up so many times to verify it was a SUPRA halfcut. And the boss even said "it's your baisc SUPRA with a 1jz engine and a manual gearbox"

No chance of getting your money back? Coz this is not what you paid for?

Dude,
Seriously I'd call them, get them to take it back at their expense and find another importer. I'm pretty sure all you have there is an engine and gearbox that is useful. I may be wrong but you'll need to find the pedals, G/Box crossmember, engine crossmember, it the piping is different you'll need to find/make all the p/s, a/c pipes to fit.
Sucks that, I know you have been waiting for ages for it.

jza70 engine crossmember - Yes, not sure on mounts.
jza70 gearbox crossmember - Probably, but measure it, its a 5 sec exercise
jza70 1jz-gte sump - Should be the same as JZZ30
jza70 manual pedal set - You may luck out here, they may be the same, if not, they can fetch a few $$
Jza70 Power steering Pipes - NFI
Jza70 Aircon pipes/air compressor? - Compressor should be the same, worst case lines will be custom ($50)
Jza70 Intercooler and piping? - Would you use the stock stuff anyway?
Jza70 Air intake piping? - As above
Jza70 Wiring Loom? (would make it a plug and play affair then)- JZZ30 wiring is easy anyway, and not 100% sure on JZA70 being plug and play, I don't think it is
Jza70 Gearbox Shifter (jzz30 ones are shorter)? - Some JZZ30 ones have the same box as JZA70, some have different rear housing. Not sure on shifter length

Dude, just get your money back! This is just insane how long it takes for them to deliver what you did NOT order (and im still waiting for your 7M  ) And if they complain just say that you have recieved legal advice concerning this matter and you will be reffering them to the ACCC if they dont give you money back, ALL OF IT. Should scare them enough...

If i can get a definite list together of what would be needed, i will let the import place know, as i told them this halfcut doesn't have all the parts i need for my conversion and the fella said he will get them for me, but once he sees the list of whats needed i hope they will just take the soarer cut back and get me a jza70 cut. But a list will be good for me to wiegh up weather or not to keep the cut and source the parts i need.
jza70 engine crossmember
jza70 gearbox crossmember
jza70 1jz-gte sump
jza70 manual pedal set
Jza70 Power steering Pipes
Jza70 Aircon pipes/air compressor?
Jza70 Intercooler and piping?
Jza70 Air intake piping?
Jza70 Wiring Loom? (would make it a plug and play affair then)
anything else?
Jza70 Gearbox Shifter (jzz30 ones are shorter)?
Thanx for your support guys.
*Bangs head in frustration* either way i look at it my supra is gonna take 10 times longer to convert to 1jz. (waiting for parts or waiting for proper halfcut)

You have a manual Soarer half-cut????! with the R154? Surely this would be rarer and hence of more value than a manual jza-70 cut?
Anyway, I can only see heartache and frustration from here on in! Is your ma70 a post '88 one? If not you'll need the power steering rack and progressive power steering ECU.
Wiring will not be plug and play but much easier if a jza70 than jzz30.
Lots of little shit like brackets for various bits, radiator and fan/shroud, ma70 pedal box is the same but you'll need a turbo clutch master syliner and slave cylinder is different to W58 gear.
Post '88 Supra mounts should be the same for ma70 as jza70 (round fluid filled rubber ones).
for crUZsida you can understand wanting to use the stock intercooler etc to save on cost and time and perhaps upgrade later.
From memory the fuel pump relay and circuit is a bit different for the jzz30 too.
Do both jza and jzz have the same hydrauliic fan setup with fan control computer and temp sensor in bottom of radiator?
All in all using the jzz30 cut would be possible, but definately more $$ and time. And probably look messier than a straight transplant of all jza70 gear into the ma70.

JZZ30 uses viscous fan, not that hydraulic crap.
Much easier.
JZZ30 uses Fuel Pump Controller (ECU), its not needed though, most people just leave a bridge between +B and FP in the Diagnostics box, or hook up a switch on the dash, or buy an RPM controlled relay from Sideshow.

But anyway i think i will take the advicefrom everyone and go for the refund and run.
(half cut cost $3000 btw)
Thanx for clearing that up Lumpy/Cruz puts things into perspective.

Photo of the shifter position would be good!
+12 between positive and coolant is fine.
Its when you have +12 between -ve and coolant you should panic.
Should I be worried that you hear a fuel pump in a half cut?

Them pics were from the import place, will try get one of the shifter.
LOL yeah i should of mentioned the fuel pupmp thing was done on a celica and my supra, and they both create a leaking air noise in the fuel rail area. Just would love to know why this is. (short Fp and B+ and stick your ear in the fuel rail area and listen.)
But that was something i always wondered when watchin a video of someone from these forums starting up there JZA70 halfcut and revving the guts out of! must of had a fuel pump and drum of fuel hidden off camera.

i might be wrong with suspension but i just remember its not a just swap and bolt conversion
plus i think the alternators are on opposite sides from a 7m and a 1j
anyway there is no conversion that is just plug and play

well they'd have to get the parts quick, and for free if they want me to buy that halfcut. They are supposed to ring me today. Will let you know what happens.

I wouldn't bother waiting for the parts.
1, it'd take them 5-6 months to get them all
2, they'd mostly likely get you wrong parts and hope you dont notice &
3, give you more weak excuses
Dont wait for them to ring, you ring them

I guess I could be a bastard and say "if something sounds too good to be true....." But i won't!! 
They'd be able to sell the halfcut pretty quick I'd imagine. get a jza70 cut and do it properly.
I'd also like to chuck my 2c in about the hydraulic fans - although perhaps harder to set up the hydraulic fan when working is bloody great and moves heaps of air. Unless you had some space contraints I don't know why you wouldn't use it.

Most JZA70 frontcuts I have seen are R154 manuals.
Sideshow is correct in saying the Alt is on the other side.
The wireing is not plug and play as the plugs are physically different sizes but still not too hard to splice.
All the cooling lines for P/S, hydraulic fan, Power steeing will be a different shape and will need to be sourced, and the A/c Connections to the compressor will be oriented differently (from memory)
