The Ford Probe GT (first gen) intercooler is supposed to be nearly a direct fit, but longer.
Your best bet is to eliminate all the stock piping and go with a nice front mount, they tuck very nicely under the stock bumper, definitely not Honda style
The stock piping, particularly the pre-turbo inlet J pipe, is astoundingly restrictive. I've used Home Depot rubber plumbing adapters to eliminate the pipe, there's some pics somewhere here or on my website. Basically anything you can do is an improvement.
There's no piping kits available. I did my FMIC with an eBay intercooler + universal piping kit. (if you're not using sewer fittings, the turbo inlet is a special size, I ordered appropriately sized pieces from siliconeintakes.com) I replaced my stock crossover pipe with exhaust pipe (steel) because that is all I was able to weld at the time. Pretty sure there's pics of that here too. Made a huge difference over the stock stuff.
(found some FMIC pics)
I don't recall the size of the intercooler, it's somewhere on the forum here.
Either way you'll be DIY'ing it, it's not difficult, just time consuming. Maybe that would be a nice summer thing for a visit to my shop, I can TIG aluminum now
