if my brain is correct, standard l2 is 68mm.. 660cc 3piston block can rebore until 72mm piston.. thats the max and the safe line. larger thn that, u hve ticking bomb under the hood.

rebore need to be done if u want to fit in larger piston.. if in bahasa pasar, korek blok la.. no need to change to 850cc block unless u have lots of money and time to do engine endorsement again.. haha.. if u rebore, better skali jalan overhaul and replace the current gasket to metal gasket. just to be safe in future if u want to run more than 1bar boost. alang2 turun engine tu replace the clutch.. use exedy 3 puck with double pressure plate (prefer ujang racing double pressure).

radiator? stock radiator is enough i think.. im using stock radiator without any problem.. hose? change la if want to be safe and want to touch up your engine bay..  dont forget to change to radiator stopper too.

walbro fuel pump? no need lah.. not reliable.. only can last for 2 years.. prefer you to change to evo fuel pump.. much more reliable and almost as good as walbro.. and quieter. fuel regulator better buy genuine. if not it will leak easily. prefer works fuel regulator, dont have imitation and life time warranty some more.

service and change drive shaft? why not this will be your 1st in the list? hahaha.. up to you..

rebore and change injector. rebore i already explain. injector u need to have at least 240cc injector.. this is for the start.. maybe combine with fuel regulator u can run 1.2 bar boost safely.. but need to run wideband tuning to check the afr. running rich: poor fc ,running lean: head will crack, running stoich: better fc and yeah!! happy boosting.. haha

high cam. need this if u want to extend the power band at higher rev. why do you need this tho? u will suffer at lower rev and ur engine not smooth anymore.. mcm naik kuda nnt.. adjustable cam pulley. ko nk buat krete drag ke ape ni? haha.. this is to retard or advance your engine ignition.. retard ignition improve acceleration. advance ignition will make the engine rev smooth till higher rev. done this only at workshop have tools to measure engine ignition.

extractor and wastegate, can improve your engine a lot.

err.. why u not planning to do fmic? u dont have problem with over heating after do this, plus it makes ur car pull better

turbo upgrade takde ke bang? piston da besar siap upgrade fuel line, extractor bagai xkn rhf3 jgk.. hahaha

first u must buy 72mm piston from toyota 2e. logically u cant fit in 72mm piston in the block bcoz the hole in the block is 68mm. so what u need to do is rebore the block to make 68mm hole to be 72mm hole. hope this help to make u understand.
its exedy.. 
200++ for the fuel pump at halfcut and fuel regulator works is 280 i dunno where to buy this thing.. maybe at sunway..
sure ok la.. just ready the money at the petrol station.. hehe.. for me 310cc injector is already too big.. 275cc is the max i would go.
aku pon xtau.. haha.. i never dyno or wideband tuning my car..
extractor? dunno if kaki exhaust have turbo manifold.. usually turbo manifold is custom made.. if use l2 engine (same as mine [promote cket]) turbo manifold is easy to find.. wastegate? i still dont have any idea nor knowledge abt this thing.. one thing for sure.. cap ayam will not hold boost steadily.
front mount intercooler

maybe u use td025.. if TF035H please sell it to me.. hehehe...
