V8 conversion

[Phil333]

Hello all.  Yep another Hilux v8 conversion bloke here.  I searched thread for over an hour, can't seem to find one on this specifically.  Conundrum, 2003 lux a keeper, love it, can't tow or overtake, while can modify bits, going the whole way n putting a v8 in it, do I, get a ls1 ls3 1uz-fe 3uz-fe or a lc 70 series diesel turbo v8 ??? .  After a long time think found right mechanic in Carrum, aware of some things that need changing, eg r151 great box, Nissan diff, flywheel, alloy radiator etc .  Of those narrowed to, which one would be best ? leaning towards Toyota engines, and of those a crate in ls3 and ls1 if can find or reconditioned / refurbished engine ?.   This lux will be resprayed parts replaced n be like new, usage is mostly town with weekends away long trips, so want no issues, just like it has been as standard.  Fuel economy, reliability and longevity are key considerations.  I would appreciate, tips, suggestions, referrals, directions to go etc I think I covered most things in relation to the engine.

Hiluxes are not intended as powerhouses.   If your towing requires such a bigger motor, consider slowing down, or a Landruiser etc. which will give you the necessary chassis strength too.   You can do almost anything with time money and tools, but the outcomes are too often worse than the beginning.    There's good reason why hiluxes aren't built with V8 motors as OEM.    Do it if you like, but don't be disappointed when it's finished, or you try to onsell the modified vehicle.   NB: B4 u start, get approval in principal from your licensing authority-they will decide whether to accept the idea.   The guidelines for modified vehicles are avail online--READ, UNDERSTAND AND OBEY them.
