cheapest temporary go fast goodies would be a DIY turbo setup with junkyard parts...
adapter plate using your hf manifold to mate a eclipse t25 to it... cheapo intercooler from junkyard, dsm blow off valve, you would need to buy an fmu, approx 100 bucks, and then get 3 inch pvc turbing, elbows, and the silicone fittings to mate all the tubing up, and then you would just need a down pipe...
is the HF DPFI? or MPFI? i believe it is DP so you would need that fuel injection conversion to get enough fuel for the turbo...
you will need to do the fuel conversion in the future anyway for any swap, so you'll need the intake manifold complete with injectors and such
there are write ups everywhere on the DPFI to MPFI conversion
another option would be a mini-me head swap which is good for approx 125 horse, some say 130 hp even... SOHC vtec head on your block, and great rod to stroke ratio so you can wind it to 8K rpm and it'll still make power...
or the all motor HF, write up is in the forums, general articles section,
HF all motor build
these are all "just for now" ideas...
in the future, you can pretty much do whatever you want with $9K
you can go b18c1 swap = $3K for 170hp, b18c5 for 200 hp swap = $4.5K, h22 for cheaper 200 hp and more torque swap = $2.3K, but more weight as well, b18b ls motor for 140 horse swap = under $2K
