a bone stock spyder puts about 120 hp to the wheels. It have excellent low end power for an N/A 1.8l (under 4000 rpm). It doesn't respond as well as the average import to the typical mods (intake, header, exhaust, etc). There's maybe 15 peak whp in a standalone ecu replacement with I/H/E (the ecu is necessary to get most of this).
The 2000-20003 all weigh within about 5 lbs of each other in csp trim since the weight was in stuff like seats, full sized vs donut spare, etc. the 04-05 might be able to have their front offset/toe box intrusion crash braces be backdated to the same weight as the early cars. It is relatively difficult to drop weight from this car. stock wheels are heavy, but interior stuff isn't, and there is barely any sound damping material, the stock battery was only 28 lb, etc. I'd say 1900 lb plus roll bar and driver is achievable in IT trim (based on what I remember from ITA rules from the 90's).
toyota's GVWR is in the neighborhood of 2550 lbs.....
the hardtop was never officially available from toyota in the US. does that matter?
