What I need is something(s) that will :-

1) Remove the 1 bar boost limit,

2) Monitor and adjust the air flow and fuel mix to optimum levels through the rev range so I can safely boost at the higher pressure (probably 1.2 bar), gaining maximum performance from the big turbo without detonation,

3) Do all this without affecting the operation of the autobox.

Now the first thing that is apparent is I need bigger injectors, 440's from 2JZ, thats agreed on by everyone, and no problem with the sourcing or fitting.

1) emanage will remove it, safc will not. Any full aftermarket ECU like wolf, haltech etc. can also be used and piggybacked to stock ecu so that it can still control the auto. that is what I am doing.

2) safc has worst tuning resolution, then emanage and then a full aftermarket ecu will be better again. However, if you don't have anyone to install or tune then that is obviously a problem.

3) whatever you use, as long as it is piggybacked onto stock ecu it should be fine.

also, I would go for 550cc's off US 2jz supra if possible or some Sard items. the US ones are low impedance so I am not sure if the emanage could handle them without resistor packs. I know that most aftermarket ECU's can.

I would recommend checking the price difference of the emanage with all harnesses and a basic model aftermarket ecu like microtech ltx12, wolf 3d etc. I was going to use an emanage but in the end I thought I would go the whole way as I didn't want to be using all sorts of interceptors like the americans end up doing.

Also, the turbo sounds like some sort of t04 variant as they are quite often .5 a/r fronts. Do you know the rear a/r? Do you know the compressor and turbine wheel diameters?

I am not sure if the 2.5" exhaust would be up to scratch for a big single turbo conversion. eg. I am running a 4" dump pipe for my 650hp turbo that then goes into 3" half way down the car.

so find out what ecu some performance shops use over there and get some quotes I reckon Smile

good luck
