i have a 95 vs holden ute with a 3.8 L V6 and i'm looking at either supercharging it or putting a 1jz soarer engine in it.
does n e one know if its even possible to put a 1jz in a holden and if so what would have to be modified, and how much would i be looking at spending???
thanks for ur help

Hey Ute Man.
Good to hear your thinking of giving the old buick boat anchor the flick!
However...
from VN onwards there hasnt been a straight 6 in a holden engine bay so that will be your first problem..
find out how big you bay is and see if it physically fits, if not its (flame guard on) probably not worth the conversion.
Other wise the conversion should be too much of a hassle, just the usual stuff, you'll probably need to make a custom gear box x member, and fabricate engine mounts, work out the wiring and all that, your standard fuel pump should be good enough for a stock 1jz.
but on the other hand why not go for the 1UZ-FE?
i've see one of these in a VS (i think) wagon, and it was pretty nicely done. Your only problem here is that if you want a manual you'll need an aftermarket ECU, but is that such a bad thing??
happy hunting.

I agree with CamZH, the 1uz would probably be an easier conversion and would give you more low down torque than the 1jz.
Not to mention 1jz seem to be the trend at the moment and so prices are getting quite high, the 1uz would probably be cheaper.
If your going to use aftermarket computer anyway then you could save heaps of money and just buy a motor rather than a halfcut.

You don't need a aftermarket ECU to run a manual on the 1UZFE, it can be tricked to work without it. The problem is the amount of $$ it takes for the manual conversion pieces.

If you've got a VS you can use the standard computer and loom, just wire it up to the 1UZ and get the program that I'll be using for my 1UZ.

Refer to page 11 of Street Commodores Mag (Feb 2002)
Perhaps this is the white wagon ur refering to: ?
- sump required 'nip and tuck
- unmodified crossmember
- engine placed as close to firewall as possible
- used supra 5 speed
- used Autronic
- 289hp@the wheels 
they said it was a mission, but with one done, they beleive they can do it drive in drive out in a matter of weeks. (Quickfit Motorsport Hornsby)

hey CamZH,
thanks for ur reply, are u a mechanic or something? i havent heared of the 1UZ-FE. what car is it out of and what sort of power does it put out?
do u know of a sort of price i'd be looking at for the conversion?
if its going to be too much i might just wait a few years and get the XR6 turbo ute. u know n e thing about them?
thanks for all your help man.

Hey again Ute Man,
The XR6 turbo sounds like a good idea 
but its early days yet.
as for the 1UZ-FE it was in the LS400 lexus and a few other things, SC400 soarers for one.
They make about 280hp @5500-6000rpm and 269@4600lb-ft of torque,
sorry for the imp. torque i dont know the conversion.
The are a 4 litre all alloy DOHC 32V V8 motor, with 6 bolt mains.
Runs a compression ratio of 10:1 or greater in the newer motors.
They are very well made and would probably do some 500,000kms before needing a rebuild.
However... They can be an absoulte power house, just look at some of the other threads on here. There is a guy in perth who runs a twin turbo one that runs 9sec 1/4s (but i have heard rumours it was smashed)
for more detailed info look around the web for it.
My old problem with this motor is the FE head, i'd love to see at 1UZ-GE, fyi the FE head is an economy head and the GE is a sportier version.
These motors are about $2500 in 1/2 cut from. and a conversion will go up from there.
But there are plenty of other people would can give you more info.

Once suitably ported, these engines have no problems revving their nuts off, don't be too peeved the thing has a FE head...

Yes, plenty of people have acheived in excess of 100hp/litre with just cams... not too shabby!

They are Quad-cam and DOHC. Its just being a V8 they have two banks of cylinders and two heads.

considering the weight of the VS is probably similar to a soarer you need anly compare the performance of a V8 soarer to a twin turbo . With about $800 worth of mods(you need a custom exhaust regardless of engine).A 1j will make shitfulls more power and torque delivery if anything is later in the rev range on a V8 than a modified 1j .
Having said that a clear choice is a 2jzgte .these have been fitted to VL's before so VS should be even easier and they REALLY are the BIG brother 1jzgte
and perform MUCH better all round

A 1j into vs would pose sump clearance issues as the 1j has 3 different sumps a forward sump, middle and rear sump u would have to make sure u get the right1.. Cutting and shutting a 1j sump is not good practice as toyota spend heaps developing them so they dont starve around tight bends( when ur fishtailing)
1UZ with delco computer?????!!!!! Is this what the post meant b4. If so thats a great idea but what box would u put behind it.
Someone in qld has a 1uz in a toyota liteace ute i know they transplanted all of the loom from the donor car to get a box that is hidden bhind the dash and controls the auto..
Go 4 it
If not there is a toymods member who works at the ford plant something to do with eng, ask him about the new falcon 6 turbo.
290kw then they tuned it back to 245kw so the shitbox v8 still had a chance at sale with 10kw more, These extra 45kw can be picked up with just ecu tuning,standard exhaust, standard cams,no parts nessacary (not a qoute)...

hey guys sorry for the late reply to this thread.
Yes it is a very good value for oney conversion. I am in the final stages of putting one in to my vs and am hoping to get around 300 hp at the wheels. (now try and get that from a v6 for under $12000.) As has already been said there are a few clearence issues with the sump and the only way we could get around it was to make up a custom one. there are also issues with the stearing rack, you can only go as large as a 3" dump and exhurst as any bigger and it simple wont fit. Also if you do you the conversiond make sure you get the ignitors with your motor as they are a real bitch to find. As for the cost it will cost you a bit more than a super charger would but you will get a massive difference is results. I think from memmory a vortec kit fitted will cost you arround the $10000 mark but then you have to consider that the v 6 is not a very strong motoe in the first place so if it is not rebuilt it will start spitting pieces every where. expect $15000 all up. thats if you do it propperly and im sure you would.
The conversion has cost me.
Motor and gear box $1800 Included freight
Cooler from Are (huge) and most other major parts like engine mount and cooler pipes ac hoses Stainless 3" exhurst Twin dumps $3900. Labour would be around $2500 depending on how much you do your self. So that makes it aroound $8200. I also used an autronic smc so add $2000 to do it this way. So around $10000 for more power over a super charged v6. and for at least $5000 less. And be a little different. how many 1jz gte poer vss have you seen on the streets. ive seen i and its in a mates shed being tuned. If you need to know any more pm me and il be happy to help. Very sorry for the long post. i just thought you would all like to know how its done.

The 1JZ in the VS would have similar problems as when I fitted a 1JZ into a VL.
They are:
Sump Clearance - made custom steel sump in new location
Oil Pickup - made new pickup to suit new location
Engine Mounts - made custom mounts using VL rubbers on bottom
Electricals - fitted 1JZ computer in same location as VL computer
Speedo & tacho - was lucky and had an analog half-cut which made the swap almost direct connection for these.
Exhaust - can only fit 3" dump pipe past steering box
Gearlever location - cut new hole and bend gear lever to suit.
There are also the usual mods required for this swap including custom tailshaft, radiator etc.
Other problems are that the oil gauge and temp gauge must operate at a different voltage than the VL ones. The temp gauge runs very hot on the gauge and the oil gauge shows full pressure when running. I can't get to the oil pressure sender to change it now without pulling the engine half out of the car. Change yours before fitting the engine.
The results are well worth the effort. The power from a worked 1JZ far outperforms anything for the same dollars. Doing most of the work yourself you can fit a 1JZ for under $5000 in stock form including buying the half-cut.
I assume that the VS would be slightly wider under the bonnet than the VL. There are problems getting to the oil filter - you may want to fit a remote filter while the engine is out of the car. The weight of the motor is another consideration - it is very heavy when compared to the RB30 that came out. It will almost certainly be heavier than the V6 motor.
