My Indecisive 4.0 V8 1UZ-FE Project
My Indecisive 4.0 V8 1UZ-FE Project
Progress! It's amazing what can happen when the J unit warms up a bit
In the end I couldn't get the coolant drains out of the old block, they're fairly soft and threadlocked to hell so they just deform as soon as you try and get them out. You also can't get a socket on them because of the pipe that sticks out the side.
So I thought sod it, and bought a new one with no oil cooler pipe:
Now like I said, my local Toyota garage were letting me try out a few different engine mounts to find a solution that worked. The first set I got were from a late-spec Soarer V8.
Here's the RH mount (remember I have them swapped at the moment so these are on the left, but I am considering revising that now) with the equivalent LS400 mount on the left:
And the LH:
As you can see the mount doesn't come out from the engine as far as as the LS400 one does, but it is a bit lower. So it'll result in the engine sitting further forward and slightly higher, which is not ideal but not a big deal because I'm going to move the points on the subframe anyway...
Here's 1 of each mount fitted to the spare engine:
The one on the left is a Soarer mount, and the one on the right is the LS400 one (the rubber doughnuts are from the tech2 kit). The fact that the mount ends up nearer the engine is great as it brings them perfectly into line with the bars of the subframe. However, the mount points on the subframe will need moving, because they're not level! The driver's side one is further forward to avoid the turbo and manifold gubbins on the 1J. I will also shorten them a little so the engine sits as low as possible, and move them backward a little. If I also swap the engine mounts back to the correct sides (as the only reason I swapped them over in the first place was to try and make them line up with the subframe) then the engine will balance on its own without the gearbox.
This is how the subframe fits at the moment with the unevenly spaced subframe mount points. Note this is actually the first time it's all been bolted together and thus far it's all using unaltered, off-the-shelf parts!
HI mate looking good, i have just started on me MR2, been siting there for months, did not read all this, so not sure if you know about the site in the US, the 1UZ site??
toxo You mean lextreme?

Here you go, and unopened 1UZ-FE, turboed makeing over 600BHP lol , no you know why i turboed my one, just wish i had the cash to get it there
I can't do anything much more with the car for a while so I decided to start stripping and servicing the VVTi engine. So I flipped the engine back the right way up and got to work...
Inlet manifold is in 2 pieces. Top piece off first:
Then the lower half, complete with fuel rails. This is one of the major changes with the later UZ engines from earlier ones - the older inlet manifolds the entry to the cylinder heads is at a crazy angle and so is the injector which harms the flow and the distribution of fuel within the charge:
I have an idea for a real simple wire tuck - it should be fairly straight forward to hide all the wires for the injectors, cam position sensors and the ignition coils underneath the intake manifold in the 'V' of the engine, and pop out in the middle of the intake stacks.
With the intake manifold out of the way you can see inside the V of the engine, which is where the starter motor is hidden. There's so much crud in here it's unreal - I even found a car park ticket from some place in Wales in there!!
I started cleaning all the rubbish out, but decided that really the starter motor needed to come out. It had other ideas and the casing broke in half...
(That round bit on the right is supposed to be 1 piece with the middle piece of metal)
After that disaster I started taking all the service parts off the front of the car that I'm replacing. I'm also going to paint up the timing belt covers but more on that later.
Timing belt covers off:
All this **** removed!! The aux belt tensioner is not going back on as I'm going to remove the aircon compressor for the initial install and run a smaller belt with a different tensioner, but the rest will be cleaned up and reinstalled:
Finally finished up with this:
Glad I bought a new timing belt idler, this one is ******!! Even grinds when you turn it
I started painting the timing belt covers. I've got loads of silver smooth hammerite which I thought would do the trick but you can't put hammerite straight onto aluminium which is what most of this engine is made of. So I used some acid etch primer on it first - I was astonished at how well it went on - so much so that I considered just leaving the parts in primer!
But my hammerite obsession got the better of me and soon this one was silver:
I plan to paint these covers, and the intake manifold and the cam covers which are painted from factory but it's all flaking off and looks ****. I may also respray the plastic belt covers black as they've started going grey.
Good progress mate, It may be in the thread somewhere but whate your planned finish date?
