I know this is a really old thread and fear the pictures are long gone.
Is there a way I can see the pics of the 1UZFE into the Sierra.
I'm in America and have a Merkur XR4Ti. A lot of people put 302 V8's in them over here.
It's a pipe dream at the moment but I'd love to see the conversion.
I'm in North Hollywood and go past to Ventura to visit my in laws. I'd love to pop down to see your swap because I love the idea of a modern V8 swap that has the possibility of being Cali legal and giving decent power! plus of course LS400's are really cheap at the auctions!Hi Merkur,
I'm getting into precisely this swap. The 1UZFE and A341E auto are going into my '85 Merkur XR4Ti. Overall there are a few things to note that are a bit of a challenge-
1) You won't be able to use your brake booster. I have the late dual-diaphragm booster and it sits right where the rear of the driver's cylinder head/valve cover wants to sit. I don't think the early single diaphragm booster will work any better. I plan to use a hydroboost unit driven off the PS pump.
2) Heater core-- the Inlet/Outlet will not work where they are, and you'll need to figure out a custom core. Since the stocker has plastic tanks and lines, modification of the stock core doesn't seem possible.
3) Sump needs to be completely customized, neither the "rear" nor front sumps will work. I have chopped up a rear sump and plan to re-weld the lower pan flange flipped 180 degrees and about 3" further back, obviously with an extended pickup tube. You need the SC400 oil filter adapter as the LS400 one interferes with the steering rack.
4) Steering shaft will likely need to be customized as the rubber donut is too large and probably interferes with the exhaust manifold.
5) SC400 manifolds fit well, but the stock cats are unlikely to work, particularly around the sway bar. If you have a later wide-tunnel XR, you might have better luck with the cats than I'm looking at.
6) Battery tray will need to be cut away where it protrudes into the engine compartment and most likely the battery relocated, depending on how low I can get the motor to sit in the engine bay.
The motor with all accessories overall fits in the engine bay pretty well with the few exceptions noted above. There's plenty of side to side clearance to the strut towers and frame rails. Sufficient forward clearance for factory style radiator and slim electric puller fans. Mounts should be relatively easy, no more difficult than any other swap.
I don't have any pics yet as I'm still a couple weeks of sump and mount work away from getting the engine mounted.
