power to weight...I had a 90 accord with jdm h22 swap. it was ok. pretty quick..plowed pretty bad through turns... nothing compared to my subie as far as accelaration and handling.
Now before I got tuned in my subie I got beat by a del sol with an h22a. same motor as was in my accord in a 600lb+ lighter car....that thing was quick..
now can you imagine how boggy your car feels with lets say 4 people maybe 5 if you squeeze and a full trunk of luggage...yea... weight is huge!
Now take your car and gut it...make it 600 lbs lighter....holy sh*t...I bet a bone stock 06 wrx minus 600lbs would be running mid to high 12's easy
Hondas are so easy to tune and make power cheaper...its not even funny. well its not...most hondas don't go over the 300whp mark mainly due to the fact that traction becomes a huge issue.
With slicks and EM you will probably get owned by him... sorry to say.
