1UZ-FE engine wiring
Discussion
Hi im currently thinking about a on going project, i want to use the Lexus V8 1UZ-FE engine, ive found a bare engine, im trying to work out the wiring loom ect, i saw a few years ago on a site somebody using FORD EDIS 4pot x2 trigger wheel (was a guide on how to get them running but after 5hours of searching cant find anything close) ect i was wondering if somebody has a link or a guide, eventually i would like to keep upgrading it, (MAYBE TWIN TURBOS) so dont want to use factory spec as seen after certain bhp ect it will need replacing im not looking at spending silly money (on budget) I KNOW THIS MAY HAVE BEEN POSTED BEFORE just looking for info to see what will be viable money wise (IM IN UK SO PREFER TO USE UK COMPANYS)
Been looking through lexus extreme forum,for info
found a 98 engine on ebay but has vvt cant find any other all have vvt at the moment would it be possible to remove the vvt e.g swap cams for earlier 1s and swap the conrods for earlier at the moment my goal is to find a cheap complete engine then start playing then adding bits and pieces e.g all wiring edis trigger wheels fuel set up

EDIS is old hat now dont use on the 1UZ-FE motor its going backwards found a 98 engine on ebay but has vvt cant find any other all have vvt at the moment would it be possible to remove the vvt e.g swap cams for earlier 1s and swap the conrods for earlier at the moment my goal is to find a cheap complete engine then start playing then adding bits and pieces e.g all wiring edis trigger wheels fuel set up

its a very tough Ford stand-alone ignition system though stevieturbo said:
Just buy a complete car, that's the best way to get everything you need.
And earlier non VVT engines are supposed to be the best anyway...and a doddle to wire up with the factory ecu.
This. And earlier non VVT engines are supposed to be the best anyway...and a doddle to wire up with the factory ecu.
Who'd a thunk it that a 27 year old ecu stored for 8 years in an unfinished Cobra could have suffered capacitor leakage............
Which is why I have just spent two days stripping the engine loom off the 93 engine in my shed to replace the 89 engine loom in the Cobra and then find that I have to change the ignitors, the throttle body,the idle conrol valve, all the sensors in both the engine and the gearbox and rewire the relay board..... and the after all that my mate comes and says
" You should have just changed the complete engine and box ........it would have been easier"
Anyway, I have now got the wiring required to spark a 1UZfe buggar up for a manual conversion down to 6 wires and three 99p relays ( one of which is almost an indulgence) although an auto box does require an additional 5 wires to be connected/spliced.
However, I do console myself with the knowledge that the "new" injector rail and ecu software will give me an additional 25 bhp from the 93 versus the 89.
And you still only need a 10mm, a 12 mm and a 14mm socket to do anything bar head removal on a Lexus..............
BTW the Lexus engine and box I have in the shed came from a £300 donor we bought for spares some 9 years ago and run for a snotter and a tow car pulling caravans and trailers.( Its swan song was dragging 2.5 tonnes of Cadillac and trailer up the M40 at 70 mph on cruise control.... naturally.)
Cheers,
Tony

Google " Nigel Wade How to wire up a 1UZfe " and its all made easy.
The answer is yes, if you can wire a three pin plug you can spark up a 1UZfe.
( BTW the Injector circuit in the ECU was b
ks-ed on mine but after 8 years did she roar on a goodly dose of easy start down its throat...)

Cheers tony just downloaded the guide, could i use a VVT block and head and replace the conrods, pistons and cams ect only asking because i can only find vvt engines at moment i know they arent that strong to tune with in standard form (not many non vvt left here in uk i can find at moment)
I binned all the Toyota guff and blanked off the egr parts as I wanted to go twin turbo with a simple microsquirt ecu and edis 8 module with a pair of focus coil packs and a 36-1 wheel pressed over a turned down Lexus trigger wheel with a ford crank sensor and Bosch 3 wire Tps .
Injectors from a saab b 204 which are 345cc and easy to find just need a slight bore out of the fuel rail and small spacers to get them in . One of the many valves left over from the Lexus is now used as a warm up air bleed and the stock pressure reg is 3 bar
Very basic ecu being batch fired and I'm not looking for more than 6 psi so it's good enough for me and very easy to wire up and it ran and drives pretty well on the auto generated fuel and ignition map .
Ecu trigger wheel and edis 8 were £350 with the other stuff scrapyard fodder .

They definitely make a great value engine.
I nearly used one myself years ago, it was just the width of the multivalve heads put me off as it would have made installation difficult in my car.
But they are awesome engines. Even on egay, plenty of LS400's for sub £1k and I'm sure if you look harder there will be cheaper cars out there with perfect engines.

The only issue I've heard of is the threads coming out of the block if you take the heads off but I don't know anyone who's had to take the heads off one yet and hopefully at 6 lb of boost I won't find out either . My motor had been passed around and tried unsuccessfully to fit into a couple of kit cars but is bone dry with perfect oil pressure and the only noise at idle is the injectors ticking . If I had left it n/a I would still have gone aftermarket ecu as however good the Toyota system is its still 20 odd years old and parts are still ridiculous and not a lot aftermarket out there . I got head bolts and head set from the us for the same price as the inlet manifold gaskets from Toyota
Cheers for the info so far, not after a whole car got no where to strip it but got shed to start building engine, been working on cars for over 15 years but my epilepsy (only started playing up last 5yrs had license revoked 3 times now) has ruined it hoping they get my meds under control so will have a lovely engine built ready to go in to the project I have in mind, least gives me time to find right engine and parts for what I want
