do i need anything else? (this is already a lot of money 
I have seen countless different options, but am wondering which one would be the best balance of cost/result.
Its a lot of money, and to be honest, the sound (almost made me cry...too good) and throttle response seems to be the biggest gain. power gains come only after even more money. i first need to get my car perfect in its stock form and only then think about the best way to improve it further..for now/ ae86 / 4a-ge forums have any info about bike carb swaps? Surely someone has done it on the cheap by now?(but modified loom) and weber 45s, putting out 137bhp at the wheels I seem to remember. ... it all starts to become a very costly excercise, end result is a 20-30bhp gain over stock if you're lucky. We are pretty spoiled by the fact the stock 4a-ge is already a pretty trick little motor in a high state of factory tune. They use them in there race cars. I've had lots of good advice from them.After countless hours on the net looking into everything about the mk1 mr2 while waiting for summer to come, I got interested into itbs.
The engine I was searching was was a 7rib non T-VIS from a '92 Corolla but after 6months searching I could find a Black Top with C56 gearbox (+torsen diff) so I ended with 20 valves in stead of 16...(for the ITB mode) but the timing belt of the Blue top snapped last year in April (my fault, I probably over tighten it 
) so the Black Top project needed to be speed up! After this the complete powertrain can go back in the AW11 and the real work can start...testing the Megasquirt with a running engine and finally tune it completly...

I had the same idea 2years ago but since I have a original big port blue top in my car I was looking for a specific 4A-GE as a starting base for a ITB setup.
To complete the project I bought a Megasquirt ECU
So far the engine is completely overhauled, cable harness is done, Megasquirt is up and running and bench tested with all the sensors and I'm now waiting to for the C56 gearbox to be transformed from FF layout to MR layout.
So in the end, I have to admit Paul is right and altough I did a lot myself it is quite an amount of effort, money, time for very little gain but I really wanted to keep a 4A-GE in the AW11 and I see it more as a hobby project rather than a quest to maximum HP.
I will keep you informed of the progress.
As for your decision, I think it is a good way of thinking, first get the car right then put more HP! And it will already cost you a lot to get the car in great shape!
Cheers,
Frank
I am a bit picky, but I am already having trouble even imagining all the things I want done. So many things, so little knwoledge on my part I do have the enthusiasm, hope it doesnt dry out 
You can't get on the Irish one without an AE86, but the Euro forum is a great source of info: - Circuit Pack

(independently of where u get the parts from).... I know its not much but like said before it was more of a hobby than anything else ... I learnt a lot and the sound was indeed amazing
