Time flies! ;) Speaking of donors, here in the UK I think I can get a complete, running 2004-06 LS430 (6-speed verison) for under £3,000. Like this (mis-identified) 156k-mile 2004 model...

Fair enough, Kelvin! It's good to be busy doing what you love. If I need to get moving on this before you've had a chance to make up a proper kit, I'll just PM you about the parts I want to purchase from you. Do you have any thoughts about using UR engines? I see that George_R can also...

Welcome to the (small) world of H200 Hiace V8 conversions! I'm not aware of any "kits", but I'm trying to get Kelvin to put one together! Thanks for mentioning engine mounts--that's another thing I haven't thought much about. Ciao, JZH

Thanks, Kelvin. I wonder if you could put together a package of parts for me to address critical conversion issues like this? I would like to use your short headers and driveshaft adapter, so buying everything I need at once (for export to the UK) would probably make a lot of sense. I can...

Fuel pump question: What pressure do I need for a 3UZ? I have learned that the fuel pump used on the 2.7l petrol version of my Hiace is an in-tank unit rated at 281-287 kPa (40.8-41.7 psi), and based on the parts diagrams and, from checking things like the level sender gasket and fuel tank...

I grew up in the South Bay, e.g., Torrance, Redondo Beach area. I mentioned on my thread that I swapped a Chevy V8 into my Porsche 914 when I was in college, and at one point in the '80s I worked at Service Center on Torrance Blvd. (a hot rod shop). I learned a lot doing my first swap! But...

Okay, my current plan is to find a decent 2004-06 LS430 (or 2006-07 GS430) engine and 6-speed transmission, complete with ECU, harness, alternator, power steering pump and a/c compressor. I've seen them for less than a grand, but low-mile JDM versions seem to get almost double that. Is it...

London, UK, but I grew up in hot rod country (So. Cal., USA). Ciao, JZH

Excellent! Thanks. JZH

Hi Kelvin, I'd definitely like to see that, but the link doesn't work. Also, I could get an LS430 instrument panel to go with the LS430 engine and 6-speed transmission. I wonder if it would be easier to use that and adapt it to the Hiace chassis, rather than adapt the Hiace instrument panel to...

Fair enough! Yes, I'd forgotten about that. Okay, 6-speed it is. I think you said your headers would probably fit, and your drive shaft adapter seem like the way to go. Is there anything else I might need from New Zealand? Will I need an idler assembly if I get a 6-speed 3UZ? The Hiace OE...

Great to hear that the ECU won't be a problem, George. The van is currently Euro 5, but diesel; the Lexus 430s are Euro 4. These are different standards, so I have no idea what the DVLA will do when I inform them (as I am required to do) that I have swapped a diesel engine for a petrol engine...

Sorry, I confused myself a bit there! I've been trying to check sump locations on the various 3UZ engines we have here in the UK, and somehow confused the SC430 with the other 3UZs, which have rear-ish sumps. At least, they did in the US models... Most 3UZ engine ads I see on eBay and...

New problem to solve: UK annual MOT emissions testing. The fact that my van is a personal import into the UK (with no identical UK model) means that it should be somewhat easier to pass the annual emissions test, but it will still have to pass one. The way they do it here appears to be that...

Excellent, thanks. It sounds like the 6-speed is the way to go. I will start looking for a complete engine/transmission, and also the 6-speed's shifter and (I think I will also need) an ECT switch for the dash. I've determined that the Hiace is only a little heavier (~125 lbs) than the...

Hi George. I've been quiet for a little while as I deal with other "life" matters, but I am still thinking about how to best accomplish this conversion. Thank you for your offer! You seem to be one of the experts on Lexus ECUs, so maybe you can help me understand which version/year of 3UZ...

Thanks, mate. I saw the pictures of the H200 Hiace with 3UZ engine. I can see that the front intake should work a lot better than the side intake on the earlier engines. Any issues with the immobiliser on the 3UZ? I think I can find someone here who can mod the ECU if necessary. I'm...

Here are some undercar shots of the current diesel/auto setup: I don't know how thick the crossmember is, but I think I will defeinitely need a rear-sump engine...

Well, that changes the calculation quite a bit! Do you have a picture of this? It doesn't sound like it would be terribly expensive... If I don't have to worry about the tranmission tail shaft I can simply concentrate on finding a complete, rear-sump engine/trans in good nick and go from...
