Clean motor even when it was still on the pallet! Many (any) miles on it? What fancy stuff did you need to do to make the 6L80e work?

Sweet.
Is it easy enough to put cart wheels on a quad axle?
This is so rad, and I am thinking the same as Valiant ^. Where does one ride said trike, so I have additional justification beyond my kids needing one? Noting that wanting to appear on police 10-7 is something that I grew out of a few years ago...

Manifold time. Was looking forward to making these, fuck me I forgot how many hours goes into them though - and I bloody need to do two! Coming along, was lazy and bought the collectors premade from Sinco which removed a bit of the work. Primaries end up pretty long to get the turbo where I wanted it, think I will need to brace the turbo to the block
Bought myself a #20 size water cooled tig torch to help get in around the collector, is so much more lush than the big chinese #26 I had been using. Also got a dual out regulator so could try my hand at back purging for the stainless downpipes and exhaust I will build. Drinks the argon but seems to work mint, makes perdy colours

Got the gearbox crossmember sorted. Gearbox fouled on the factory one as had a raised centre section but ended up being able to mod and reuse by flipping it so raised = recessed Welded in some 5mm plate to reinforce it where the gearbox mount was gonna go.
Built a platform mount on top
Installed with new urethane mount
Also got the first of two new driveshafts made up. Tremec-side has no slip or universal so important to get right, positioned the gearbox mount so that could use the factory hanger, will probably add some reinforcement there though as not much to it. Anyone have any idea how beefy the hanger actually needs to be? Factory one is pretty wimpy...

Hurry up!
Haha, here are some more pics youve already seen. Starting to catch up to current state though...
Engine fits - with 2x4 offcuts for engine mounts. The truck LS intake manifolds are super tall and even dropping engine low as possible with low profile sump was surprised to see bonnet fits. Get about 20mm clearance btw bonnet and engine cover, was stoked to be able to use that manifold as although fugly they make more power and torque than the LSx car manifolds
Steel engine mounts. Left the toyo outrigger thingees intact chassis side, and fabbed adaptor plates to work with some generic urethane mounts that were for some ye olde jeep thing... Needed to get trigonometrical interfacing the plane of the existing outriggers to block V. Tried by eye to start but math > measuring shit by finger width.

Out with the old, in with the new (ish)
Big lump of a box fits the tunnel - massive relief there! Shifter linkage gonna be tricky though...
LT1 motor had a rear sump but motor was mounted high enough that it sat above the crossmember/steering rack. Was hoping could do the same with the LS but since the motor has to sit low to get the box down the tunnel - no deal on the factory rear sump...
First solution - got hold of a commodore LS1 sump which puts the bowl up front. Still fouled the steering rack so second solution - hit the scrappy for some 8mm ali plate
Wish I could say the above worked out, but sadly the final weld kept cracking as it was cooling down so needed to grind out and reweld several times. I finally got it to stick (by piling on blankets and controlling the cool down), stoked. Went to bolt it up and sump was warped to fark due to putting so much heat into the stubborn bit. Commodore pan went in the bin (or rather the scrappy for a $8 rebate on a weekends worth of frustration), and gave up on the factory sumps.
Third solution was one of these ex the US, much better fit, more oil capacity than any of the factory sumps, and has a port for the turbo oil feeds built it.
Only problem with the above was that the flared bit of the sump was a bit too wide, and wouldnt clear the crossmember brace on one side. Sump is zinc coated so decided to leave that unmolested and deal with the brace instead. Cutty cutty:

Oh and re turbos, zing! Taiwan-fresh GTX3067R. Will be x2 once I recover from paying for the first

Yeah, last setup didn't run a huge stall or anything but powerband was all up top so if you wanted to drive it quickly (without caning it) you ended up using a fair bit of throttle. It would put a grin on your face above 5k rpm but the kun hiluxes are way heavier than the previous gen luxas so really needed something with better mid range to make me feel better about the fuel it drank. The trick with turbo sizing has been to choose something that will provide the mid range but not be so small that you can't cruise under boost - time will tell on whether I made the right choice there...
Re the LS9 gaskets yeah they are oversize of the 5.3/4.8L bores but they are cheap for the quality of gasket and a LOT of people using them on the same motors and making stupid power reliably. That discussion has played out at length on the US forums and people argue it either way but prolly half the 5.3/4.8 builds on there use LS9 gaskets because they are so well proven, with not one instance I could find of one letting go (below ~800hp at least).

Re economy, better than the last motor I hope as was a pig, but not really sure so will have to wait and see. Is 0.9L smaller than a factory LS1 so a touch better than that hopefully, cam is bigger than LS1 though... Am taking the opportunity to swap to a manual so that will help with miserly highway driving.
Speaking of which, next up was to purchase one of these bad boys:
Is a TR6060, and is gonna be a pain to make work given remote shifter and fixed output flange but T56 would likely die behind that motor so decided to man up and go the reliable (but cunty) path. Also bought a fancy new clutch (Mcleod twin plate). Is a strange feeling buying a clutch that is worth more than yer daily...

Heads off for a skim, new uprated valve springs and seals, and then back together using ARP head bolts and LS9 head gaskets which are GM gaskets made for boost. Also replaced the lifters (LS7), and swapped out the cam for something more turbo friendly. This is pretty much following a formula based on what the US guys are doing with these motors, my engine is a gen IV LS so has the bigger rods and with mods above these motors seem to hold together pretty reliably up to the ~600kw mark.
Cam is pretty mellow but will piss on the stock cam everywhere.and idea is keep it snappy out of boost (ie retain low and mid range). Also has pretty sweet note (random Youtube link below). should confuse the 1UZ connoisseurs...

Hey fellas
After some years outa the car building game have been making some progress on a new project, its not old but thought Id post it up here since have lurked for years here and seems like oldschool's one of the last well frequented NZ fabrication forums...
Have always been a fan of the american muscle truck thing, even though doesnt seem to really exist here. When shopping for a sensible new family ute a few years back a saw a tidy '05 KUN Hilux that had been tastefully transplanted with a drag-spec LT1 350 chev and 4L60E auto. Not sure I have any pics from when I first bought it but did a few things including deleting the chromy bits to this spec
Having built a few cars in the past and having always ending up jaded over how you seem to burn more money than you could have ever dreamed, this was the first car that I bought already modified, as figured may as well make good on someone elses financial haemorrhage. Problem with that is after owning the truck for some months I found more and more stuff where the quality of 'craftsmanship' drove me insane. Stuff like washers spacing out the custom front brakes to make them fit (R32 calipers and bigger rotors), modified crossmembers reinforced with mild steel chequer plate that look like theyd been cut by a blind person (no deburr), abortion exhaust that was unremovable without cutting etc. Also the LT1 had way too big a cam for just punting around the streets day to day so ended up deciding to reinvent the shiny lux...
First came some BC coilovers up front and new wheels and rubber, but most importantly the LT1 had to go:
Keeping the american muscle theme its a '08 Silverado donk, aka 4.8 LS motor. It is the smallest of the LS series engines, couldve bought something bigger but plan is to turbo it and hopefully get the best of both worlds being fuel economy underneath boost, and insane crazy power when so desired. Also bought some bits to upgrade the baby LS
To be continued

Good numbers man, torque curve is fat as! I always knew there was more left in it, though gave up trying to get more power after kris tuned it to white knuckles @ 16psi, will be super loose on new tune! Much left in the injectors at 19psi?
-
Theres a boss already on the downpipe mate, unless you got some funky oxy sensor with different thread...
-
Sweet, what was the story with the clutch?
-
I recognise that wheel arch, looks less filth encrusted than I remember it... Howd the injectors go? All sweet? Matt here btw

er70 wire makes stanless turn brittle ..
if you dont know dont post
Errrr, I presume that was directed me. I do know and thats why I said it wouldnt be pretty. I wouldnt touch MIG for anything other than mild, unless I was building a boat...
-
That'll work mint, cheap too. You could MIG it, but it wouldnt be pretty (even with stainless wire)

Am so sold on this, been checking out the one on yer other thread and looks ridiculously fun. Ive got a fair bit of asphalt wonder how that'd go...
How did you design it is there extensive forum-based literature or did you just make it up? Your other one looks a bit light on power is that why you going 180cc? Have always wanted to build something around a CBR mc19 motor but I spose that might be a tad much...
