Surpra?

Post by emknaps »

Hey folks, been a while since i was last browsing these forums.

thort id do an update on my shitty old surf,
after a major breakthrough only made possible by one of the members of this site "SUPRASURF"

anyways,

vehicle in question:

1990 VZN130 2 door (red interior YUK!)

bought for $600 on trademe with a leg out of bed on the V6.
yanked out the V6, mounted a 93' JZA80 2JZ-GE six to the auto with some custom engine mounts i made at work.

Image

Image

No mods were needed to mount the engine to the trans, a bellhousing swap is all that was needed. tourque converters are the same even.....
though the gearbox did need shifting backward which was made possible with a LN130 box crossmember and modified shifter linkages
the standard V6 sits forward of normal diesel position by 50mm to clear the shitty exhuast cross pipe.

auto is fully manualised with a hand full of diodes and the shift location switch.
engine is run Via a Megasquirt ECU which i have used in allot of my cars and a few of my mates cars.
A very cost effective sollution.

4inch suspesion left was then installed, which was sourced from a guy in CHCH that SUPRASURF got me in contact with
which not only enabled me to put 33/12.5/15 rubber on the truck but also ment i could leave the sump mostly untouched.

lots more room for the exhuast was also a by product of this lift kit.

i run landcrusier rear shocks and pajero rears for the front shocks, it ride hard one the road but quite nice over the hard bumps when offroad.

Its 1st trip was a trip from jafa land to the national park for a lap around the "42"
this was with knackard front shocks and road wheels.

Image

before i put tyres on this thing it owed me $900, (not including the price of the engine cos i stole that from my supra)
then i put some KL71 Kumho's on it with landcruiser offset rims which more than doubled its value, but i sold my winch to fund the tyres ( no i don't plan on getting stuck).

A week before our next trip (queens birthday weekend annual 4x4 excursion) i have the tyres and a large ugly bullbar mounted.

Image

Image

i would like to have some sort of cold air intake sorted before i go as the pod filter just plain sucks hot air off the radiator (logged 80deg c air temp on the Megasquirt)
but ive yet to come up with an idea to solve the problem.

anyways,id best go do some work on the pig.

Cheers to suprasurf and his mate in chch for the lift kit, and many thanks to the creators of this website. it is a damn good source of info and like minded folk.

Daniel.

Cheers,

its not water prof.

ive not had it in any water just yet, knee deep puddles sure but no wading has been done.

i know from just water blasting mud off the engine that it gets into the plugs and creates a miss fire.

i think a new dizzy cap (its cracked) will help and a new set of leads also may help.
other than that there is nothing i can really do but drive fast enough to keep a decent bow wave happening.
all the electrics other than the alternator are up high so we will see how it goes...

Cheers,
Daniel.

How much did the 4inch susp lift set you back and where did you get it from? Is it susp only or is it body as well?

I spent a LONG LONG time searching for the lift kit,

was put in cocntact with a guy in chch who had one in the back of his shed.

i dont think they are redily available altho i have seen similar kits on e-bay

just 4 inches in the suspension, no body lift.

i paid $250 from memory, but ive not idea what the going price is.

Thats looking really good. Water proofing the engine is a bastard - you need to plate over the entire valley between the cams and use lots of silicone - talk to Hiriklux, he's getting good at it now :)

As for cool air - go buy a length of 3" exhaust tube and a 180* mandrel bend of 3" tube as well and make a snorkel - lots of cool air 2m off the ground and outside the engine bay :)

Good work, nice to see another 2JZ-powered beast out there...

Hey thanks for the tips fella's

Im realy not sure of this engines suitability to 4x4ing,

perhaps i have just been spoilt by my injected chev that i had in my last surf,
and perhaps i need some 4.8 diff gears as it has 4.3 and does 150kph in second gear.

these engine really are peaky with very little torque to speak of below 3000rpm
I would like to repower it with a large capacity diesel like a 13bt or some such thing
but for now, ill take it to the the Pureora forest this weekend and give it a damned good thrashing,

and go from there.....

Cheers,
Daniel.

Ive heard the same. Maybe fit a second transfer case? Im not too knowledged on the possibility, but it would fix your low range.

dont go near a diesel. Yuck. Stick with the petty. possibly a supercharger or just another v8

I've got, 2JZ-GE w/ supra ECU, Standard Prado Auto and Transfer Case, with 5.29 Diffs.

On 35's with the standard 4.3's it would do 105kph in first
On 35's with 5.29's it happily does 60 in first... on 29's you just get torque steer and no feel in the steering wheel with your foot flat, and this is all in a truck that weighs in at 2.4 Tons.

Offroad with the 5.29's ... its great. if you can do left foot braking its as low as you need to go for most stuff.

I have been thinking of fitting a supercharger, but can't justify the cost of it + computer + extra fuel.

hiriklux does the rock thing and has done much more than me with his 2jz...

Thing I love most, if I kill the motor $800 will buy me another one. Oh and being able to overtake at 100kph..

You didn't even hit the rev limiter... btw what exhaust have you got? is it a JDM 2JZ-GE (ie with a MAP sensor)? I'm having real trouble finding a correct wiring diagram.

I didnt hit the limiter cos ive set it to 7200 and its a timing retard/ soft limit rather than a harsh cut like the OEM ECU.

the exhuast is side exit and one resonator, very minimalistic.

i have the JDM diagram, let me find it for you.....

http://www.mkiv.com/manual/1995_electri ... index.html

this one is good, i have downloaded it to my pc.
and altho i dont use it for my hilux i still have hte car the engine came out of so it still serves much perpose.

is your ecu running the trans?

Looked at that one, doesn't match mine :-(

That was the plan, but as I used the original A343F Trans, it has the wrong speed sensor. Tried a few options but none worked, so had the old diesel comp running the auto for a while, but just about to install a custom ect ecu.

What ECU are you using for motor and trans?

Also I have just put 2lbs of air pressure into the trough in the top of the motor and about to add the dizzy which should mean no water issues ever.... I hope. Will test it by putting the whole front end under and see if it runs.

that diagram has both GTE and GE ecu wiring
the GE has no AFM, only a MAP sensor.

the 4x4 trans has 2 speed sensors i think
one that has the cable for the speedo itself
and the other is for the auto trans....

knowing how both trans' work im certain the 2JZ ECU will run the trans.

as for me.....
i have a Megasquirt ECU. which is a yanky born open source project.
u get a bag of bits and you solder it all togeather. thats for the engine,
the trans has been manualesed with the help of a few diodes and the trans position sensor.

Unfortunately it doesn't seem to match mine. Got the motor, full loom ecu etc, but there seem to be some subtle differences.

one that has the cable for the speedo itself
and the other is for the auto trans....

knowing how both trans' work im certain the 2JZ ECU will run the trans.


The difference is that you have an A343H which has an electronic speed sensor, whereas the A343F has an analogue. I tried an A to D converter but it didn't work, also looked at the cost of adding/replacing the speed sensor but the $$$ amount was waaay too high for my budget.

What did the megasquirt cost ya? How easy was it to tune?

I have the full diagram to manualise the auto, one the auto is working right, I'll be ordering the bits I need to do that...

Ah, you trans has the normal transfer case, not like mine, which is an auto transfer case.

i get ya.

do u have a link to the wiring diagram for the manualised auto trans?

from experience you need to add a few connectors into the shift position sensor plug as the one on mine had a few missing as it did not have a shift position indicator like my supra does....

what does the diesel auto trans ecu use for a speed sensor??

megasquirt was cheap, 140usd but u have to make a few mods to the dizzy..

No but a man I know will send me one once I send him the wire colours.... He seems to have different wiring colours to me.

It has 1st, 2nd, D, R, N, wires off the lever that run into the computer

what does the diesel auto trans ecu use for a speed sensor??


The signal from it is analogue where as yours will be digital. Hence why I tried an AD converter.

megasquirt was cheap, 140usd but u have to make a few mods to the dizzy..

Was think about an aftermarket ecu as I'm having idling issues at the moment, but I'm starting to think its a broken wire somewhere as its intermittent.
