Hey everyone, new to this board. I have a mass collection of toyotas ranging from a dozen parts ae86's, a collectors condition ae86 and a mint sr5 that was converted to gts but has a bad motor. A few caldinas, hilux, 4runner, and celicas.
I am planning to take the sr5 and drop in an lt1 v8 with twin compound turbos (yes four turbos) out the hood with hater pipes mated with a th400 for now as I have many laying around, until i can find a good borg t56 or 6062. This will be a drift / drag dedicated car, and will most likely never see a legal road in the rest of its days. The engine fitment is no issue and will possibly go dry sump to lower the center of gravity further.
The main question here now that you know details, is the rear end. My father who has owned ae86's since before I was alive claims that when he brought his ae86 to the dealer in Europe for basic services, there was another guy who was there multiple times for new axles under warranty with a STOCK motor.
I have a 4runner frame stripped down with a good rear in it. Internet claims these are easily swappable if you have any fab knowledge to reweld mounts and align it. My question is, is how is this 4runner rear going to handle up for 600hp clutch drops? And over 400ftlbs of torque at 1400rpm? (Until I get better heads and cams to up the boost further for a final goal of 800hp years down the road)
Assume fabbing will all be done in house. (Tons fo welders and machining mills) My origional plan was a ford 8.8irs trak lok from one of my old burnout cars. It ended with 7 or 8 pistons and rods through the block and oil pan at 15psi boost. After research a hilux or 4runner rear is the way to go. IRS fabbing would be a NIGHTMARE!
Thanks for response. Pic is of the burnout car getting its rear dropped out. It has been weathered for 4 years in a bush so don't mind the rust and leaves.
(Added photo of motor that will go in, has about 6 to 8k dollars into internals motor was built with circuit track in mind - photo is old and still of the beginning of fabbing the tooth wheel trigger and cam sensors)
