1uzfe + turbo is the way to go
I have not had mine on the Dyno yet but feels an easy 650hp at 1 bar boost and 6,500 rpm rev limit with massive low down torque and a T88 that is producing positive boost below 3,000rpm
Pro's
Engine and loom available cheaply
with Soarer mounts drops straight in
Adaptor plate available to use V160/161 gearbox
Light weight aluminium block weighs 100kg less than standard 2JZ block
Weight distribution is much better than with a 2JZ with all the weight behind the front axle.
Con's
Custom loom and exhaust required
Can't think of any other's that don't apply to a single 2JZ conversion.
When Ryan returns I hope to get this mapped to around 1.5 bar and I am confident that the stock engine will take this amount of boost, time will tell ...........
