Constant 4WD to Part Time...

[Meldge]

I know that these are both Toyota Engines, but posting here for a broad outlook.

What would be cheaper if anyone knows, buying the 2JZ front cut, or buying the 1FZ front cut and then adding a turbo.

The other is Engine Capacity: I know the 2JZ is a good, strong engine (only a 3litre aswell - I think) but surely a 4.5litre Turbo engine would just be so much better.

Fair enough it has not been designed for a turbo, but if it breaks it can then be rebuilt with stronger internals allowing for even more HP...

Why? Are you going to drag race the thing?

I'm sure you could put an EFI V8 in there with less hassle and cost.

Sounds like you're just doing something different for the sake of being different. If that's your thing then, hey, knock yourself out. But dont kid yourself about how much it's going to cost.

[Meldge]

Well yeah, I would like to have it sitting as low to the ground as possible, and yeah pretty much would like to be able to play with all those idiots that see a 4WD as a slow car, and then 'try' to waste me.

I have not had a quick car for a while now, and I am missing it.

Plus, I am going to build another truck for wheelin' as i don't want to use this one anymore.

a 2j is twin turbo is it not

[Meldge]

Yeah apparently in a sequential setup, rather just one bigger one though. Don't want to have to replace two turbos with another two. Rather change manifold to single turbo setup and go from there.

[83 lux]

from factory the 2j is a twin turbo so why would you need to replace both if you get a good motor then i hope that the turbos will be just as good

[Meldge]

Well yeah, you would 'hope' it is in good nick, but if it isnt your buggered. Heard a few stories about importing engines. Mostly it's all good, but there have been some bad ones, that's all.

They are both Straight Six, both Twin Cam, would both be turbo, but one has bigger capacity. Internals would not be built to the spec of the 2JZ, and fuel consumption might be worse in the 1FZ, but still Cubic Inches is still the way to go in all applications isn't it?

[Hybrid]

Meldge, have you looked at the specs of these engines? I'm guessing they would be around the same price. I have no idea in that department. By the looks of it you wanna build a fast street car out of a four wheel drive. If thats what you want it for I'd go the 2JZ.

1FZ-FE 165 kW 387 Nm
2JZ-GTE 208-239 kW 433Nm (variation due to jap spec)

The JZ is a proven performance engine. It has plenty of support and in stock form flogs the 1fz. If you spent the extra money that it would cost to turbocharge the FZ on the JZ it would be unstoppable. (cept when everything around the engine fell apart)

[Meldge]

In the end i think the cost of a rebuild and adding a turbo would be too much. Power output would be unreal though.

I could just adjust the boost on the 2JZ and with an intercooler, it should be a bit of a monster.

If i already had a 1FZ 'laying around' I would go with that probably, but I dont, i still would still have to graft another box onto that to get away from the tranny case.

The cheapest option I think would be the 2JZ. How hard would it be to modify the stick shift, i mean in a supra it would be short as hell, i don't want to have to lean down to far to change gears.

[whatever]

what does 1FZ comes out from? I don't much about it(is it a LC motor).

It all depends on what you have planned for the engine, if you are planning to do a single turbo conversion and the internals. The cost of converting both engine should be about the same. manifold, turbo and plumbing back to the intake.

Only thing I can see is that 2JZ is one of the proven performance engine from Toyota. Bigger Cubic doesn't mean much unless everything else is the same, such as strength of the block and heads, also availablility of performance parts.

I'm sure you could put an EFI V8 in there with less hassle and cost.

The Efi V8 makes around 10kw more but shit loads less torque than the 1fz so you are wasting your time on that conversion really,
Especially as he is looking to turbo the 1fz
For interest sake, the Safari turbo systems for the 1FZ make 240kw @ the flywheel at 3.5psi, and at 4.5psi they are making 265kw(approx), hows that for food for thought!! All this from using a piggy back ecu too......

These engine will easily take 9>10psi with no internal mods, not even a decomp

From another forum i have posted a few threads on a toyota crown that has a 1fz engine converted into it and Turboed,, the results are fairly interesting/amazing

The 2jz engine/front cuts are not cheap, around $7k for memory, where as a brand new 1fz,s have been advertised in the Sydney trading post a while back that had damaged rocker covers only from transit were $1800,, add into that a turbo/ manifold etc and you are still along way from the 7k

If your keen i have a rebuildable 1fz (which i was going to turbo for my 80series) here for $500 was a good running engine but has been sitting around now a while,
I know of a turbo manifold sitting around plus a new garret to4b turbo also,

So i say go with the 1fz, U will be surprised

[83 lux]

1fz-fe comes out in the 80, 100, 75 series

[Meldge]

What Auto Box would i run with the 1FZ if I go that way, something with 4 gears and will cop a flogging...

Turbo 400 or Turbo 700. Maybe the Landcruiser standard Auto for this engine, but what about transfer...

I might even just put it in this truck, and lift it and run big wheels, that would be good all round - especially with the torque figures that the Toyota Crown is putting out.

[I.M.P.O.S.E]

A mate has a 2JZ in his car
It has made 375KW at the wheels!! (with more potential) Plenty of power available out of these puppies!

Also I have heard rumours of a 80series Running big turbo setup (on 1FZ) making like 400Hp running around gold coast, maybe built/tuned by Chiptorque! Anyone know anything more about this truck????

[Meldge]

There are a few 80s out there running turbo 1FZs... Big power potential out of these cars.

If i bought an engine with no wiring loom and added aftermarket ECU, does this take care of the lack of wiring, or would it link into original wiring?

I have never played with aftermarket computers so I have no idea.

[ORSM45]

if it were my decision id go the 2jz. half cuts are around 3000.

the turbos are already sorted out for you. they can handle 2 bar in stock form. there is a 'stock internal hp, top 10 list of supras' think the highest one has a single turbo putting out 1000kw @ the fly. thats with std bottomend. toyota over engineered these motors, and they are awesome.

if you wanna get real crazy, put a 1jz head on a 2jz. they flow better. and with the 2jzs bigger capacity it loves making power.

if your looking for an auto, find a halfcut with an auto. it simplifies alot of things when its already there for you.

dont go by the stock kw figures as with a boost adjustment and some bigger injectors your already in a whole different league.

from memory the std turbos can handle upto 18psi.

I think the 1FZ would be a better option.

I have had someone mention that they have an engine lying around, without loom. How hard would a loom and computer be to come by, or would it be easier to get an aftermarket ECU wired in instead?

Also if I pulled a gearbox from a 4WD and was converting it to 2WD, how do I go about this without needing the transfer case?

Still use the standard Auto, but changed somehow or what?

Are the 80 Series Auto Electronically shifted or manually shifted (via cables)?

If you new that after 40000kms, you would get a new car, would you care if u missed an oil change??
The 2jz is single turbo, 2jzgte is twin sequential. Both make more power and torque than 4.5 cruiser., however, 4.5 with safari turbo makes 240kw/550nm on low boost, and off idle, not at 5000rpm. There is one on exploroz for $14900 ATM (92 fzj80 gxl safari)

Gday again
I dont think the 2jzgte has sequentials, but twins instead...thats why the 2jz went back to one big turbo. Might be wrong....Tuff80's site is awsome...

[Meldge]

If I acquire a Constant 4WD Automatic from an 80 Series Cruiser with the transfer, is there a better way for me to switch between 2WD and 4WD other than locking and unlocking the hubs.

As the front driveline would still be spinning if I unlocked the hubs.

I would still want the option as 2WD would be good for burnout comps and certain driving techniques, 4WD would be good for hillclimb and track events. It would be good to also see how much power is lost between 2WD and 4WD.

So I guess the only other option is a part time transfer on the back of the auto, is that correct?

[dow50r]

Thats what i run in my 80.
You could disconnect the front hubs, run locked highrange on the rear diff, run constant when you have it parked (and it wont go anywhere) locked hubs, constant 4wd and low range. The electrical part is fairly easily overcome...u use the cruiser wiring harness and relay box and switch :-)
