Well, i searched wikipedia and thats given me a basic insight, but whos had experience modifying them specifically the 3uz?

my chaser has a 1uz currently, but im looking for abit more grunt. unfortunately a set of billet cams are mega bucks and a grind and valve clearance reset is alot of money/work. However i have come accross a 3uz for reasonably cheap and wondering if installing it, running a link extreme with sequential ignition and injection and custom headers is gunna give me enough grunt to warrant spending the little extra coin to buy it and install it, also considering that i will be able to sell the 1uz to make some coin back..

Don't mean to go completely off track but have you looked at supercharging or are you keen to keep it N/A?

A mate of mine had a 3UZ in a Hilux, with Link, pod filter (I think) and extractors, and was high side of 220kw. Was running a W58.

To be honest I've always been dissapointed with the output on N/A 1UZ's, maybe its because of the 'F' head?

Perhaps forced induction is the best bet?

They can be downright slack behind an auto

twin td05s would wake it up without going overboard

YEh, have tossed up the idea of forced induction. If i charged it i would go with a 6/71 stack out the bonnet! Its just alot to spend lol. Also hav talked about twin turbos, theres alot of fabrication required and u end up with a shit load of piping in the engine bay lol.

Pretty keen to keep it toyota lith. My fabricator mate has been pushing the big single idea lol would be cool. But its still alot of piping. And got run a big 4 inch dump pipe back over the manifolds.

Haha yeah I figured, just having a little troll- they are pretty epic motors though!

True, dump pipe being a hassle does make sense... turbo V8s are just sheer awesome though!

Pro-charger?

by **YeMs** » Wed Jan 18, 2012 7:35 pm

we are going to re-evaluate the turbo idea. on the 3uz that is. i dont like the 1uz.. and im going to be running a link extreme anyway, and we were gunna build custom exhaust manifolds aswell.. so why not turbo it. lets do it and keep it auto... powercruise next year pencilled into the calender.

by **YeMs** » Wed Jan 18, 2012 9:07 pm

well after some more serious investigation, i just dont think there is enough room to comfortably fit a turbo around a 3uz in the engine bay.

what power can i expect from a 3uz, link extreme, extractors and a milled out plenum with larger throttle body. is 260rwkw realistic?

OMG so shiny! · by **Dell'Orto** » Wed Jan 18, 2012 9:18 pm

I wouldnt have thought 40kw from a throttlebody would, but I've not had a good look at one to see how restrictive it might be

260kw @ wheels from an engine which makes under 230kw@fly stock with such simple mods sounds unrealistic to me, of course without specifically researching it - but 260rwkw is a heap for an NA 4.3litre which isn't a high performance motor.

What is it particularly about the 1UZ you don't like? And is there a size difference? The 1UZ would feel like a totally different beast if you put a turbo on it - a sensible sized huffer for making 300+kw would be making easy boost by 2000rpm which would immediately have the motor feeling much torquier than its NA guise.

Definitely reckon should go 1UZ with twin turbos. The work involved in fitting a 3UZ and doing the mods is not worth it for that minimal gain.

the 1UZ responds very well from forced induction from what I've heard.

just a pair of small frame turbos like a pair of T28's will totally bring the engine into the "holy shit this is fun" catagory.

akane, does a 3uz not bolt up to the 1uz mounts etc?
