Brings back memories. H22 swapped EG and EK’s were the “cheaper” way to pump over 200hp back in 2007-08 where I live. That was in the times when we started to get JDM TypeR engines but those were often more expensive than the car they were put in. So many people either went the B20 Frankenstein version (CR-V block with GSR head mostly) or H22 since these were domestic and almost half price from ITR or CTR drive trains. I remember seeing ONE K swapped civic, they were unicorn rare in those days.
Wait until you find out about Duesenberg. They made 400hp supercharged straight 8 monsters that cost more than a doctors annual salary back in the 20’s and 30’s. They were much faster than even race cars of the era. IMO the first relative “hypercars” if you compare what else was available.
