ok.for ur limited knowledge..lets agree to u :D............. well
point #1 ballancing........well i dont think i need to answer that as with limited knowledge kids have about rx8s and 2jz- matings,,,,,,even 15 year old boys can sum it up:-$
Point #2 Traction controol..... if u own a mehran and u want traction controol installed.leme know ill take car of it
yes buddy org output 232 bhp and my out put 1200 bhp which spares 968 bhp ...............i hope baby math helps 
i am not sure but ill give u a good example.................a coblers son was studying in our class back in o-levals, st patricks karachi----same school wheare musharaf studied from--------if he thaught about his son the same way hed put him in gov public--------same way u know parents from avg backgrounds make sure there kids make it to the best school and ALHUMDULILLAH most of then do- same way when ppl make a journey from karachi to lahore, it seems impossible- ppl used to travel from pakistan to mecca fro haj on camel and on foot............i belong to that religon and my elders have left examples for me...........same way 5 yers back i was in a condition wer i had humble beginings. and wheare i am today,,,,,,i swear upon my ALLAH swt no one is willing to agree that i have reached to a point wer i have workers working for me calling me sir--------and the same way wer i see my self in the next 5 yers is again unimmaginable today
of ur availability subject............for the sake of an argument lets agree with u...........now u see i will make the audience laugh at u which will proove ur whole reply was vague as u. usitting down for 2 minutes on pakwheels u have scanned the entire japanese and dubai markets :P.............wow man we must replace u with the nasa satalites as america wud want a gprs system like u. there fore one more reson which proves ur emotions ride ur mind and ur car rides u 
just answer me one thing have u ever been to japan............dubai is irrelevant.
japan is were each and every car is born and when it comes to motor racing bubba boy..............japan is far ahead of all...be it the states...it is a country wer drifting was invented...time attack, auto cross drag events....
do u know most of these events use 1000 bhp cars on their entry leval.
when it comes to spare parts japan has enaugh to feed the whole world, as it is doing and will countinue to do for a very long time. so do u think it is difficult to source engines in japan.........
i hope u didnt misconfuse it with torkham wer the notorious corola diesel is the only engine in demand since motor known to man.
2nd point about the money.......if u think i just woke up 1 morning looking arround for 2jz then ur in delerium....rods,pistons,etc as u mentioned i was planning to bring down a pre prepared engine......but if possible i wouldnt mind building one on my own..............
and then again if u think,,,,the way ur saying to build a 1200 bhp 2jz at 15 lacks,,,,, i would consider it a miricle. as only a good Garret GT 76 upwards setup would cost 75% as mush as u quoted.
so thats why it would be mush better to purchase it from a retail vendor as reconditioned
