Well, ITBs typically come at the expense of intake runner length. Intake runner length is carefully calculated to generate low end torque through harmonics. A really short runner will lose huge amounts of torque (and therefore horsepower) below 5 or 6000rpm but will gain some power above that. If you have a high rpm race engine that is designed to operate exclusively between 5000-9000rpm they are really useful.
Throttle response is something people talk about when they aren't making real power. Drag racers don't need it because they are already revving up prior to launching. Road racers don't need it because they are rolling into the throttle from the middle of the turn as traction will allow (unless they suck and are just stomping on the throttle as soon as they get onto the straight).
If you are worried about boost threshold being low enough for your driving habits, then pick a small turbo. I choose to have a larger turbo for the sake of lower intake temps and reduced exhaust backpressure. If I stomp on the throttle below 3000 rpm on the track then I'm doing something wrong. I should have downshifted. But I understand that value on the street, and it is a useful trade-off to go with a smaller turbo for street use for this reason.
A modern turbo will generate positive pressure within a fraction of a second if it is within it's operating range. For mine, that is above 3800rpm and up to redline. Good luck!

Yeah compared to the Miata the E30 is a nightmare. EVERYTHING in that car is different compared to the Miata as far as feel goes. I got so used to the E30 hating me every time I did something that when I jumped in the Miata all the friendly feelings I got from driving it were so foreign. But yeah I love my E30. She needs a lot of work to get her more street friendly though.
Suspension is another priority for me as well. The suspension on the Miata is stock and is surprisingly still really, really good. I would like a little stiffer ride, though, just because I'm used to it. I'm going to start searching for a nice set of coilovers.
Another thing that I'm worried about is the clutch. The clutch is so different between the Miata and the E30 that I'm worried I'm going to prematurely destroy it. The E30 clutch is a Stage 2 so it's very heavy, the Miata clutch is like stepping into a bowl of marshmallows hah. Not used to all the travel.

That was when I was in Rhode Island. Built it, went to Germany for a year for study/internship at BMW, then returned and sold it to build a Miata. It was a fun car and great how many parts could be frankensteined together from other BMW's and Porsches. Alas, it didn't win my heart and it was time to move on.

I'm going to be in the market soon for some new suspension; apparently I lied about the current suspension being good. The front struts are blown :/. I'm looking at some different coilover options so if anyone can recommend me some good street ones I'd be happy to consider them. Currently looking at Bilsteins, Megan coilovers and Stance GR+ coilovers.

I did some searches and the only *useful* thread I could really find on my specific question was how to reuse bilsteins from an NB. I guess that could be an option but I don't have anything as far as aftermarket suspension goes so I wasn't sure if that was the best option.
You'd think there'd be some sort of "Rate Your Suspension Here" sticky or something.
