k24/k20 setup is pretty quick. For some things though is it really worth it to drop all that cash into it? If your shooting for setting fast Honda/Acura drag times then its understandable to be spending a lot for a swap and parts. Heres my limits, figuring I spent around $4k on the EK for the car and mods. I want to swap in a GSR motor thats $3k? Then turbo just shooting for 300HP so $3k for a turbo and parts? I could probally sell the D16Y8 for $500 so subtract that. $9500 It will be fast and have all the nice features but once I start getting near $10k all I think of is being close to a WRX. You can do just about anything and anything its how deep your pockets are. People do AWD and RWD conversions, huge motors even V8's mostly trying to compete for something the car wasnt really designed for. The RWD Integra was made for drifting and competing against 240's and what not but they spent $32k or something rediculous for the mods. The B18 in the integra is a pretty good motor just throw some boost into it. No need to swap out something with good potential.
