Not sure why I need to punish myself this way,guess I just got tired of waiting for a better challenge,and tired of looking at the collection of oil pans,manifolds and other pieces taking up space in the shop.Anyways,picked up a fairly clean,one family owned shitbrindlebrown MKIII NA Supra with a blown head gasket for a great price,an 04 LM7 pullout with all the accessories,harness and PCM for $550,an almost free LS1 intake manifold,still not convinced this is a good idea or use of my time,
but needed a good excuse to bail on Xmas activities...
Engine/trans is now out,clutter out of the engine bay removed and most of the Toyota harness deleted of the non essentials.Grabbing the engine tomorrow,then deciding on which transmission to use
have a turbo 400,700R4 or 4L60E to choose from,also have a 4L80E but crap,its a 4x4 unit,I guess I'll save it for the next one.

Looking forward to seeing the progress on this. I almost pulled my LS swap out of my Lexus SC300 to put into a MK3 Supra, but backed out at the last minute.
im two slow years into my lsx mk3 supra swap, im doing an iron block lm7 bored to 346"
Ive been taking pics however no build page yet, id figured i would wait until i get close to turn over time before i begin posting.
my car is an 89 NA targa top and ill be using a r154 5 speed
The pile on the left is what I think I will need of the original harness
2004 5.3 just will open it enough to swap the pan and intake and a quick peek inside,might just need a camshaft
This is what really needs a LS swap,original 1974 L48 with a tire shredding 165 horse under the hood, one of the weakest suck Corvettes ever built,but on a sunny day one tends to forget about that...
swapped my 92 supra to lm7/th350 in 2008. its now twin turbo, 4l80, backhalved, etc. very fun street car. if I did it again I would just use the kit that's available though...
I can't wait to see this build. Please, please, don't touch the paint or interior of the "poopy Supra". In a world where most of those cars were beaten to death and rattlecanned flat black by teenagers who painted the interior we need an example of what was "Hot" back then. Great sleeper look. DC shoes decal is ruining the vibe though.

Yeah,them stickers annoy me too,will scrape them off for sure.Gonna try to leave it as bland and unassuming as possible,that will make it all that much more fun.I'll be spending the next few days in the shop,hope to get a bunch of work done,just got back from a brief vacation on the opposite coast of this island.
Looks like its time to beat that transmission tunnel into shape,,CTS-V manifolds will need just minor adjustments,fabbing up some mounts looks easy at this point.

Toyota factory tool for stretching tunnel,along with a selection of BFH's.I probably should have stripped the interior and opened up the tunnel for more height,but this is a down and dirty cheap *** build.
Transmission and engine mount butchery,uses stock 4L60E cushion.
It takes too long to get parts shipped out here,especially with the holidays,so grab some rusty steel plate and get to it.More scrap steel
will be welded up to the stock mounts.
More gussets, grinding,de-burring and painting to be done later

How about some shift linkage mutilation-disassemble,move arm from right to left of transmission
Hack up Toyota shift linkage,mix in a pile and weld it together,then bend and tweak as required,this will take a bit more altering but should do the job.
Now on to the next challenge,ah screw, it just polish the alternator and cut a hole in the hood.
Never realized how high and how big these truck brackets and alternators really are once that tall truck intake is pulled off.
Shouldn't be too difficult,lop off the top part of the truck mount,fab up a couple of plates and spacers to move the idler and alt down and to the left,and I'll use the much smaller Supra alternator and save this one for my next truck.P/S hoses look simple,possibly just cutting down the Supra pressure hose and reflaring/adapting a Chev tube and fitting to it.
F-body,C5 or CTSV stuff would be nice,but just not available around here and I'm not dealing with the time/expense of shipping it out here,already spent more on freight in the last year for my other vehicle's
parts than I have spent on this project so far.For the $500-700(Canadian $ is almost back on par with the peso again) the nice stuff would cost me,I can cut,drill and tap a lot of aluminum or steel plate.Don't worry,the alternator won't be sticking out of the hood (it would be fun to watch the faces of the horrified onlookers for about two minutes though) the cops around here would have this thing loaded onto a flatbed and the plates cut off the second one of them caught sight of it...
Been dragging my *** on this one,work and the usual BS getting in the way,anyways fabbed up an alternator mount,anyone know a part#/application for a smaller diameter idler?It will be a PITA checking the PS fluid,not really any worse than my stock1974 C3.
Grabbed a driveshaft off the rust pile in the backyard,amazing sometimes how these things fit together,got the run out down to a reasonable amount,if it shakes too much I'll at least have something for the driveshaft shop to work with.
Chop,chop.
Some clean-up and grinding to go,actually slips inside nice.
Back at it again,someone had broken the front pump drive tangs on the 4L60E,around here idiots think used 2WD ones are made of gold and priced accordingly,so for the price of a used trans,bought some parts and went thru it.
Building a harness out of all the harness odds and ends I have dragged back the last couple of years.
Engine and trans in the car for the last time,hopefully...
I'm lovin' this car and the ingenuity going onto it! Thanks for posting your build.
Crap! No ingenuity is gonna save me from this one-actually had to give in and buy a brand new L99 water pump,just no way around it,that's gonna cut into the beer budget a bit...
