Engine options for yn60. V6 Commy or 1UZ??

[Windsurfer0206]

As it says above which is the best i want to hear it all. main thing i do with the yn60 is road trips some offroading go to the snow. so im looking at open road milage and in town milage. main thing for me is the efficiance and the cost of putting the motor in the car.

so how much will it cost me about to put the motors in and what will i need. i want to go manual either way as i hate autos.

I have a yn60 with a 3y-e and a gearbox that i need to get rid of as its a 4 speed runns great but dont like how it makes the engine rev in 4th. it is sitting on 31's but want to put 33's or 35's on it so will end up doing lift some time so i can go in deeper mud and snow.

i can get a complete v6 commy car for $750 (getting details soon). 1uz would have to hunt around. would then just need to get gearbox. what would be the best?

any info from you guys that have done either or both would be great. i thought about just doing a 3rz but to find one is almost impossible and then there about 2k anyways and your only getting about 150 hp. I wouldnt mind a 3rz as i know there pretty much a bolt in and do a little wiring and exhaust work but finding one and cheap yeah right.

from the little bit of looking the v6 is looking the way to go but i havn't been able to find a detailed step by step and costs.

well ill wait and hear from you guys on your thoughts

hey chris,from my point of view and what ive heard v6 is better,dont kno if youve seen the thread but iv just picked up a 94 vr for $400 so im going to be doing that asap,cost wise im sure its less too,buying the whole car is a far better way of doing it as you need motor,loom ecu and im planing on chopping and rearranging the xaust aswell so that gets used,some guys even take the fan,then sell off the rest,you then need a box,i believe theres a range you can use but the r150 or r151 are what people comonly use,ive got myself a r150 which is the 5speed diesel box off the back of a 2.4turbo surf,and then the expensive bit which is the bellhousing adaptor,clutch setup etc,if the commy is a auto i belive you can go one of 2 ways,remove crank and change for a manual one or buy an adaptor plate,this is because auto cranks have a 6 pcd bolt pattern as apposed to a manual which is 8pcd pattern,all the bits between motor and box are expensive,ill be doing a full write up but at the mo its looking like ill find a manual crank and flywheel local,then order the bellhousing via marks or dellows in aus,bonus with both is theyre a long bellhousing which pushes the motor forward and will sit exactly where your current motor sits leaving all your box / driveshafts untouched and not needing any modification which is a big bonus,and if youve got money theyll even sell you motor mounts which bolt strait to what youve got in there now so its a simple bolt together job,or so im hoping

R series gearboxes were not in "60" series surfs. So if you were on the hunt, you need one out of a "100" series surf. The common box behind the 2.4 TD on 1986-1989 models was the W56. Just check the vehicle tag before buying one (if you can).

[Sadam_Husain]

Either of them are a good proven choice for a conversion, both motors are cheap to buy but the cost is all in the conversion and your probably going too have to get flywheels and shit made up to run a maunal gearbox so do your research on the conversion costs first before you end up stretching the budget too much

Personally if I was going to all the trouble of a conversion I'd be getting as many cylinders under the bonnet as I could

[gimmemud]

Go the V6!!! Absolutely love mine.
Sitting in front of a g52 box which should bolt straight into yours? although not as strong as w56 or r15* apparently. V6 has got better low end power (IMO) and plenty of it. A few people i have talked that have done both have said if they do it again they would go v6 over lexus because it's better for 4wding. http://www.lextreme.com/ has heaps of info on lexus conversions.

[LOLYF]

Yeah V6 is better for 4 wheel driving, thats why you see so many commadore powered trucks winning winch challenges

[Petemcc]

Haven't heard of many lexus motors shitting themselves but lots of commys... It seems like they dont like the revs or angles. I still think they are a great motor but might pay to look into why so many give out. In saying that its only about $500 for a replacement

comilux has just gone to a custom sump with baffels etc they have the same issues as the old supra engines, not many car engines are desgined for our sort of driving. If you want something on the cheap do the commy conversion its great, easy and cheap.

i think its a opinion thing
but on paper .. uz make more power everywhere than a commy v6
that also means that it makes more tourqe ... everywhere
havent driven a v6 comy hilux yet .. but ive driven piles of 1uz ones ... s/c ones... turbo ones(500+hp anyone)
and realistically .. IMO its to much power .. maybe thats why people like the v6 ... its more driveable

[Engineer]

only reason i chose v6 was the physical size of the 1uz, theyre a tight fit. they make similar torque to a 1uz but at 1800 rpm instead of up near 5g. a whole car is $500. and i know the owners of several 3.8s in winch & club trucks and theyre still going strong and they sure as hell get a hard life!! nothings cheap.

[vvega]

um no
uz makes 200 lb ft @ 1000 rpm and 260 lb ft @ 5600 peak

its a urban myth that they have no bottom end ... when @ 1000 rpm there making more lb ft's than a mighty 1kz makes at peak

the most comonly avalible commy v6 makes 220 lb·ft @ 2800 peak
they do get better when you hit ecotec though

[rangimotors]

and just to compare a 6m supra engine makes 170-192 ft·lbf (230-260 Nm) at 4400 rpm

but she loves the jandle and with 4.8's and duals i'll have plenty of gearing

there all good engines and its great to see such a variation
i just wanted to dispell some interweb myths
i have a uz in mine .. 4.88's as well .. and its fairly sprightly

yea i can imagine, i'd almost bet my boots that ya get better fuel economy as well

[vvega]

on high way crusie i get 100 km per 10 liters
round town its drops ..
BUT the ecu helps a lot thats the beauty of aftermarket managment .. you can spend hours getting it .. just right

[Pedro]

Yeah V6 is better for 4 wheel driving, thats why you see so many commadore powered trucks winning winch challenges

the engine comes into winch challenge???, i thought it was who had the dearest/fastest winch.

the V6 is currently the national champ in trialling for the last couple of years.

horses for courses, put a supercharger on a v6 and it is a very compact torquey powerplant, where as the 1uz are not overly compact.

[vvega]

completely agree there a TINY motor i mean really .. one you get over 200 hp i think tires and traction comes more into it

just trying to point out that the comment "v6 is better for 4 wheel driving " is a rubbish comment as there is no "best" engine. there are far to many factors and variables to make such a broad comment.

[Windsurfer0206]

hey thanks guys. lots of feedback which is great. now im going to throw a wrench into it and ask to compares the 3rz with the 1uz and v6. so i have been told the 3rz will easily spin the tires free of mud with its 150 hp and the guys in the states have taken them up to 2000hp for drags and so on. i know jdub is going 3rz cause he recons theres enough hps and torque with it and its pretty much a bolt in and wire up and he know someone with a few. what do you guys think bang for buck and installing cost? think jdub said he can get one for between 1500 and 2000.

cheers chris

[vvega]

bang for buy put a 1uz out of the ideal
realistically
buy a 1uz with factory managment ... 1500 ish make sure you get the right sump
engine mounts ... 325 for a bolt in solution
bell housing ... 500 again bolt in
flywheel and clutch 1000 bucks.. again all bolt in
rear crossmember and drive shaft mods can you do this yourself.. if not .. 600 bucks
thats the motor in.....

the comes .. exhaust .. water pipes rad etc

then wiring ... its not hard.. but there is a "way" to do it

personally i think even doing it yourself and just useing shops to .. do a little of it .. 5 grand driving
pay someone to do it .... 10 grand inc motor drive in drive out

if you can do EVERYTHING yourself ..... 3000

so in conclusion
making everythign your self 3000
buying some stuff etc 5000
drive in drive out 10,000

its the sound coming out of the exhaust that counts commy 6's sound dirty but lexus v8s sound soooo dam sexy up on the limiter

[wopass]

see now i have to totaly dissagree on that, i think any engine on the limiter sounds like absolute kack

i have only heard a few 1UZ plants that sound good loaded but as soon as they hit the limiter...EEeewwwww.

[vvega]

@ 5k limiter mine sounded horrible
@ 8k .. it sounds a lot better

[flyingbrick]

@ 5k limiter mine sounded horrible
@ 8k .. it sounds a lot better

LOL!.

vvega.


Sounded far better when it had no limiter and revved way out to fcuk-knows-what.

I thoroughly enjoyed playing with your pedal that afternoon.

Its on video somewhere too

[vvega]

thats was a 8500 limit
you never use it though peak power is @ 5500 ish ... needs cams .... and there comming
