In your case I'd go with the Hondata unit. It's more than capable of doing the job you need done here. Even if you start to tune yourself all you have to do is get the datalogger option added on later down the road and the ROM editor.

Only downside is that you have to convert to OBD1.

What are you using as fuel management right now?

I have one more question actually. How are you going to fabricate an IM with ITBs? The purpose of ITBs is mainly to get more air into your engine faster and equal amounts into each cylinder. That's only done through using open TBs with no plenum of any sort. I know that Skyline GT-Rs use an ITB setup with turbo but I have no clue as to how that is setup. Mind enlightening me on how your setup is going to be?
