converting S.T 20v 4age to turbo

[corolla.fx-gt]

i am wondering what i would need if i wer to turbo my S.T 20v 4age..
apparently i can use 4agze internals?? if so what internals would i need from the gze
. dont think i can use my 20v head would have to change to 16v head..

what else would i need?? i would need a different ecu but not sure if i can also use the one from the gze or if i would need to buy a link ecu which are expensive... also any ideas on prices on all these things would be helpful

much thanks..

Do a google search, there's a lot of info on this topic on various forums from Aus, NZ and the US.

why would you need a 16v head? lol there are plenty of turbo 20V 4AGE's out there...

thought i would need 16v head if i wer going to use pistons out of a gze because they are 16v so the top of piston would be shaped for only 4v per cylinder

Son , you have alot to learn the ze piston has a low dome the middle valve would not come close to hitting the piston, if you want to be more safe get a 1mm metel head gasket from HKS, and you will be able to sleep at night.
