ok so im a toyota technician of about 5 years in Australia...otherwise i just call myself a mechanic not a dodgy one aswell

lexus and toyota all in all toyota is a fwd lexus and a lexus is a rwd toyota lol but you guys get what i mean

ive sold my evo 6 tommi makinen edition last year which had 360 awhp which was a very quick car

since ive always been a toyota fan ive got my eyes on 2 cars but i need all the info i can get....ive searched internet everywhere for info but cant get much and would like to hear it from you guys and i know every forum has a search button lol but id like to make my own thread

ok 2 cars...im gonna be choosing one and making it a rocket with a twist

one is the very rare but genuine is200 legana model with a 1uzfe vvti engine with 120,00 kms and its manual

and the other car is a gs430 2006 model 3uzfe vvti engine with 100,000 kms sequential auto

pretty much id go the gs430 due to technology and more newer and luxurious car but!!

but if i was to spend money on both cars
im talking headers exhuast cai cams custom intake manifold bigger throttle body diff gears and a ecu(need help on ecu...was thinking going standalone motec but not sure if its possible most people reckon best way is piggyback but apparently the stock ecu tries to overcome the tune is this true?) was going to go dual tune of e85 and 98..

twist is i wanna keep it naturally aspirated but fast since im a mechanic working on the car isnt a hassle

next question is...is it worth it to do up these v8's naturally aspirated? and will it be able to run a 1/4 mile time of 12.5 which is where i wanna get to..if anything will i have to go the supercharger route

i just want some genuine guys to answer my questions genuinly and lead me into the right direction and please i don't want no criticism either

BTW am i posting this in the wrong forum

 

trying to make serious horsepower in almost any of the Toyota motors will be extremely expensive, whether 1UZ, 3UZ, or any JZ variant as well...

All of these motors can be made turbo charged for a fraction of the cost of making real power N/A...

a 12.5 in the 1/4 will require 300-350 wheel hp in an IS or GS... This will require at minimum cams, individual throttle bodies, ported head(s), bigger valves, etc... Even then, they would benefit from even higher compression ratio and a very efficient exhaust...
