Okay kid, check it out. It was a stupid question not based on anything more than what you've read on the internet about what people think is "jdm tight drift spec" on RB's. It's not only not worth it, it's not practical, and their are other reasons. Nobody has done it for a reason. Spend $10k on a non-turbo RB30 build with a 26 head, high compression, yada yada. You still have a car that will not have the power of a bolt on and tuned stock turbo RB20. You would not get more than a passing "hmm, interesting" from the people that just saw you get beat by a stock turbo'd RB20, let alone anybody else. Also, 18:1 compression? Did you just pull that number out of thin air? RB's don't have more than a rudimentry variable cam timing system, let alone anything like vtec, their head design isn't as good (for n/a power), and you can't rev RB30's (which would be your best bet for n/a power) very high.
We are giving you s*** for asking a dumb question. Roll with the punches, don't get to butt hurt, and move on. People will remember you on here more for taking a good ribbing well than for asking the stupid question----unless you throw a temper tantram now, you'll be the 14 year old kid with the stupid ideas that can't take a little internet flaming.
You choose.
