Do you do a lot of work yourself? or know people that can fab stuff up for you?
IMO $2500 is a lot for onl 40 more HP, you'll also need a bigger exhaust - $700-1000 for neuspeed. The chip they give you does all your fuel so that is cool and for only 40 hp more your talking like maybe 5lbs of boost. On a stock compression (which is?? 11:5:1?)
5lbs is about your max else your going to detonate those pistons, melt the 85,000 mile rings and be out of an engine.
Personally unless that comes with a limited slip, which I don't think they do, having that much extra tork in FWD your gogin to get a lot of wheel hop (unless you upgrade all your bushings to poly and suspension) and really make you just spin the tires in 1st, probably in 2nd as well.
If you do all yor work and/or know people that do - you could get new forged pistons/rods for the bottom end - $800 or less, t3/4 turbo for example (there are so many) for $500 and that will put out 25 psi plus supporting mods another $1000 most likely and put out 3-400hp (all dependent on what you make your compression and set your turbo psi at)
there is a lot more that goes into it than what I listed. I was just stating that for the $2500 your spending - maybe around the same price to $1500 more you could have a hell some serious power - of course you have to know some people else double that for labor. All in all once you start moding and getting into superchargers/turbos your talking lots of $$ and time dont' forget frustration.
I had a 97 gst eclipse - (bad accident totalled in oct/05) that put 433 to the wheels dynoed, currently building a 92 awd eclipse track only car - both turboed so I am biased but my boy has a grand prix GTP with a super charger - In my FWD and his we would be equal in 1st gear (he had about 250 hp or so) but when I hit second his tork helped him no more and I put about 7-10 car lenths on him by the time I hit 3rd. People will say turbo lag sucks but it helps you in a fwd.
Boost is boost no matter if it's a charger or turbo - the PSI amount is what will toast up some rings and or more damage
