1UZ vs 350Chev vs LS1

[NZ_AE86]

A 1UZ in a 4WD Hi-lux can out tow any other service vehicle we've used!
They sound better the a pushrod shitter any day!

Whats it like for fuel consumption when towing your ae86 plus trailer (to manfeild for example)?

I towed my ae92 on a heavy trailer + tools + spare set of wheels/tyres with a 2005/6 maxima 3.5 v6 auto jobbie and man it guzzled.

The fuel used doesn't change if your towing! 1 tank (115bucks) will do about 360kms towing or not! But I have not been out-towed by another service vehicle yet!!
So about 1 tank to Manfeild and back with heavy trailer and you know how many spares/tools/fuel/wheels I bring!

Lol gotta have the quickest tow vehicle eh!

Hmm wonder if changing the diff ratio to make use of the torque would make much of a difference.
Im looking at getting a 80's surf and will more than likely do an engine conversion at some stage. Maybe a 5mge or 2jz would be abit easier on the fuel.

Our local ambulance uses that chev engine, its the biggest piece of poo's engine I've seen in a while. Its the second one the ambulance has had since new which is 1992 I believe and the first one only lasted 400,000kms, which I guess is alot but a Toyota should get more. The second engine cost $10,000 to be shipped from the states and put in the ambulance, not sure if this is good? But it runs like crap, the mechanics are round there every other day and it just won't stay in tune and uses a couple of litres of gas to go maybe 10kms down the road. Also 3 speed auto FTL!

The only positive is I live one door down from the Ambulance station and there's nothing like hearing it grumble into life on a quiet night while I'm sleeping. [drool]

My father is an ambulance mechanic for otago/southland. The chevs are the most reliable things they have ever had. The Te Auna one has 700,000 odd k's on it now, still going sweet. One of the Wanaka ones recently blew a big end a new crank cost $370 or something, cheeper than a regrind Much better than the shit merc and fiats they get now, some of the parts prices on those things are just stupid. Good work accountants in charge of st johns And why do you need anymore gears than that when you have that much torque to play with? And a couple of L to go down the road...ok

My father in law has a 350 chev in an old 1970's land cruiser, that dosent even notice when there is a boat on the back.

And the noise it makes just RAWKS!!!!

I was more saying the auto makes the engine drink alot. And it does use that much fuel, its improved a wee bit but it's still a thirsty machine-and thats stop start driving to go down the road, not an open road. There might be something seriously wrong with the engine but noones ever picked it up.

Have driven a few LS1's, auto and manual for extended periods

Have done the same with a few lexuses (lexi? haha)

No comparison in my books


The UZ motor - compared to most things its a wicked torquey V8 sounding thing and most people are just used to 2L or maybe 3L cars at most, hence why its such an eye opener and people think its the be all and end all compared to their own 1600 or 2l turbo. Yes they can rev but if there was no rev counter thats just academic.

LS1 - well you pay for what you get. Commodore with 5 on board will pull up hills in 4th like they arent there. Motoring mags rant about no low end torque but thats purely in relation to whats up top. Its a world above most motors you can buy these days.

Yes the chev has pushrods etc etc but personally I don't give a shit, I'll take results over the way they're achieved anyday. End of the day its almost a 6L motor that starts and idles like a japanese 2L, will pull from any RPM in any gear, and sounds $&#$% porn while doing it all. Who cares if its stone age tech if it gets the job done. Its like old school arnie vs some jackie chan - you may have all the tricks in the book but doesn't count for fck all if the other guy brings a rocket launcher

I agree with you to a point Ako - in a stock celsior or soarer the 1uz is very underwhelming, whereas an ls1 commodore (my main experience was in the first of the vu ss utes which i drove regularly) go pretty well - I wouldn't have said that low down torque was THAT good, but they certainly do wake up when you rev them

Have you driven/passenged a manual 1uz in a vehicle thats not a frigate? (ie: not a soarer or celsior)?

Because they go very well - even in a relativly heavy 100 chaser it went very nicely - and in a hilux/hiace they boogie!

[Ganjasaur]

The Toyota 1uz or perhaps the Nissan Vh41 or vh45 both are excellent priced engines with HEAPS of potential.

www.lextreme.com has an excellent forum with lots of info about 1uz's.

The Nissan v8 I dont know much about other then that it is used widely in the stockcar scene and aparently cleaning up the old pushrods.

Fuel usage on the 1uz is pretty damn acceptable on the 1uz. But I dont think one could say the same about a 350 chev.

But yeah I would buy a new japanese v8 and help bring them into the foreground of performance engines.

Peace

Dont know if hes sold it, but could be of interest

[toyrota mota]

Whats the difference in size between a 1UZ and LS1?
Also most of the LS1 are detuned heavily, i mean just a tweak to the ecu and they make another 10kw or something. 250kw is not hard to get at all from a LS1.

What about a 2jz or 2jzgte? I mean a 1uz makes 250hp and 260 Ft. Lbs.
A 2jz makes 220 hp and 210 Ft. Lbs.
And a 2jzgte makes 320hp and 315 Ft. Lbs.

Proably not the 2jzgte their dam expensive, but a 2jz is going to be a fair bit cheaper than a 1uz and theres not that much difference between them performance wise.

[Mr Revhead]

i bet a 1uz would be cheaper than a 2jz

[toyrota mota]

I dont know for sure, but just from what ive seen 1uz's and 2jz's go for.
2jz $700
http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Toyota/Engines-drive-trains/auction-120953003.htm

1uz $1000+
http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Toyota/Engines-drive-trains/auction-120075484.htm

The above prices may not be a good indication as everyone is trying to rip everyone else off on trademe these days.
But please give me some idea what someone should expect to pay for a 1uz and a 2jz. As sometime in the near future I plan to buy one of these engines for a project. And where the best place to buy these engines from is.

[Voyeur]

My personal choice in a street car would be 1UZ. consider the pro's and cons for each
1UZ
all alloy (better chassis balance)
quad cam
32 valve
6 bolt mains
forged crank

LS1
should be at the end of chain stopping my boat floating away
more info http://www.smokemup.com/tech/ls1.php
pound for pound pretty much the same

[Mr.Phreak]

Having driven both my sad old UZZ30 and a later model JZZ31 (Not VVTi) I'd have to disagree with that

And you guys bagging the LS1, have you ever had a look at them?? The only reasons to go UZ over them would be price, availability, the UZA70 has been done before so answers to questions could be found and keeping it in the Toyota family.

[Looonie]

The 1UZ is a better engine for a street vehicle than a 2JZ-GE, and is around the same price for similar quality examples.

I realise the LS1 would be the best option, but as mentioned, at 3x the price its not really feasible.

Thanks for all the advice guys, 1UZ is the go.

Now to save the coin and finish the other projects first

If only the 1UZ sounded like the 350 chev

[Mr.Phreak]

If only the 1UZ sounded like the 350 chev

Hey, C'mon....it's not like it sounds bad

[edwagon]

The 1uz sounds great with a good exhaust! Different to a small block, but just as good I reckon!

[sergei]

it sounds even better with intake

[Looonie]

Anybody got a 1UZ with an exhaust they want to come and show me?

Its been about 8 years since I drove a UZZ30 soarer with exhaust, intake, suspension, 18s and wayne gardner racing kit...

It was nice and torquey off the mark... baked up trying to leave an intersection... but it didn't feel like it really had the "urge" I'm used to...

Still.... put it in a car thats not hideous and overweight and I'm sure it'll suit my purposes nicely
