So you have the extra oil lines and egr plates???

It'll cost you the same as doing a gte engine swap.

make sure you look at your fuel system also and realise your compression ratio is higher so a metal head gasket and arp hardware is advised hell just go 1jz or 7mgte swap a lot less agravation

i have: a comitic 2.0mm h/g, arp head studs, 4an braded stainless for the oil pressure, 6an for the return, 6an for the coolent, the manifold, fresh rebuilt ct26, front mount and 2-1/2" piping, tial bov, and tons of check vaulves. and why the hell would i need egr plates... irelivent because i made them of 1/16 aluminum plate. im getting an areomotive fpr. once we mock it up we will make a down pipe of 2-1/2" flaring at a 30 degrees to a 3" down to a 3" exaust y'ing of to 2 2-1/2" side pipes made of manderal bent piping. I just need info of how the ecu will react to a higher air flow... and if i will need to get larger injectors to run low boost (about 6lbs) if i bump the feul pressure to about 60lbs with a 1 to 1 rise. The factury injectors are either 360 or 380cc injectors. i fugure if i hook it up and pull the timing to bout -5 or 10 degrees with the factory safe gaurd pulling on the happening of knock it should be a good enough set up to prevent pre-det. by the way the head is ported .075" over on the intake and .055" on the exaust. if wort comes to worst i have an 88' turbo i will just put the ecu and wiring harnis in along with the coil packs and extra knock senscor... no biggy, and i dont want to lower my compression because my uncle has a 526ci mont carlo with 14.5:1 compression and runs hes blower at 16lbs (13% load rate) and makes around 4000hp and runs 5.60's in a 1/4 in the high 230's to low 240's mph. my brother and i have a business "Lethal Addiction Racing" with all the machenery we could ever need; which makes my life easier.

It'll probably think WTF when it gets all the sensor readings. Especially if the air flow or density sensor is before the turbo. I would recommend reflashing the ecu to a 7mgte program and fine tune it from there. Just my $.02.
