B18c5 balanced and blueprinted, sleeved, forged pistons/rods, stock compression and cams, upgraded valve springs. Supercharged to about 10psi. Proper injectors, adjustable cam gears, and tuning, of course.
Should come in about $10k (would be a stretch) and be reliable as hell.
Or, save $2k and do a poor man's type r.. but do all the same stuff listed above.
