Thought I'd start a build thread. I've posted it on LCOOL but as that is a closed forum I've decided to start one here too. I've always thought an HDJ105 would be the ultimate wagon (just a shame Toyota never made one), but didn't realise how much I needed one until a few months ago. I had a nice HZJ105 for a few years (315k, pre 02, 2", dual batteries, tired injectors, cracked screen, bald tyres). I thought about upgrading to an HDJ100 but the price and IFS put me off.
Loved the HZJ105 actually, but the power, fuel economy and 5k service intervals were starting to get up my nose. And I couldn't shake the feeling that I was missing out on a lot with the stock 1HZ. Turboing it did not appeal at all, and was actually quite an expensive route. So I sold it and bought this manual FZJ105 (260k, dual batteries, 2"/285s/airbags, twin ARB locked, HF safari snorkel, wheel carrier, DVD player). Had/has a few small niggles but overall really good. After almost 10k very sick of petrol fuel bills
Then with the leftover money bought the contents of this ute. Got it from Nerrandara wreckers - good to deal with, Nick seems a nice bloke and he kept throwing stuff in. But we'll see when I start pulling it apart to freshen up (seals, water pump/timing belt, manifold clean/EGR block/intake heater gut, valves etc.).
The most important bit
Hopefully I can get it all in before the 1m warranty is up :?
I also have a 600x300x76 intercooler coming, and will fab up the 3" exhaust with various bits I've salvaged. Also have an electronic boost controller but will get it up and running before getting into hotting it up. Nick threw in a prado 120 sub tank along with both HDJ tanks. Hopefully I've got everything needed from the wreck - pretty much everything electrical from the dash forwards (inc. kick panels, keys, ignition/immobiliser , cruise stalk), everything fuel related, PS lines, AC lines. He also included an 80 series sump (but no pickup, to be addressed) and bellhousing/fork and engine legs. I picked up a new CI HD clutch (if I go wild in the future this might crack it but rated for upgraded VDJ79 so should do for the moment). HDJ flywheel also on its way. Just need some engine mount rubbers. I'm keeping the 4.3 diffs for the moment - with 285s the revs are close to stock just need to sort the speedo.
I'm hoping to have the mechanical side sorted in a weekend. Then I will be attempting to splice the wiring myself, hopefully through week evenings and another weekend (this is the more hazy part)...
Currently my biggest question is the ECU - it's an auto. I spoke to Brian from PDI (very nice helpful bloke, wish I could afford one of his intercooler kits) who assured me he's done some with an auto ECU and manual box and all is fine. He even had a customer with a manual running like crap (diagnosed faulty ECU) and put an auto ECU straight in and ran perfectly.
However - these were all with chips, long term I would like to end with a chip but doesn't fit the budget right now. There's a guy that converts them posting on facebook that swears the auto ECU will not run properly with a manual. Others say it will throw codes and not let cruise work. There is a thread on here (a few years back) where someone mentions they had to put a manual ECU in to get an HDJ105 to run properly. There is also another covering this topic but it's on a pre 02 system which I believe is quite different? I could make up dummy loads with resistors etc. in place of the shift solenoids but if they have to constantly change this wouldn't work. It would also make an already big job bigger...
If anyone has any comments on any aspects fire away, I hope I'm not missing anything major...
