custom intake plenum
match port the intake and exhaust manifolds
aftermarket cam
bigger injectors and fuel rails and fuel pump
big intercooler and radiator
the above mods are big $$$$$
the biggest thing going for the tb42 is that the bolck is the same as the td42 so it can handle lots of pressure (you would decompress yours to about 7 or 8 to 1 and a N/A td42 has a compression ratio of 22.7:1)
I really hope you achieve this kind of power.
it can be done My old flatmate has 4.5L petreol 80 series landcruiser ( i know its a toyota) with 750 hp at the flywheel its a mean machine and all of the above mods (and more) have been done.
good luck with that!!!!
Cheers

would a standard gearbox handle that kind of power???? tony do you know.
refering back to my mates toyota (sorry) once he started making over 550hp the gearbox will regularly poo itself..He is on the 8th gearbox atm

A standard gearbox in good condition will handle it no problem. If you look at the trucks that competed in the Outback Challenge there were Nissan Patrols with turbo TB48's and supercharged 6 litre chevs putting out in excess of 600hp through Nissan manual gearboxes. In the last OBC some of the teams had switch to modified Nissan auto gearboxes which were also able to handle the power.
Is your mates Toyota a 80 or 100 series Cruiser? If it is I'm not surprised he's going through gearboxes (and probably front diffs as well), they're just not as strong as Nissan Patrols in the driveline.
