way too much bro....the 1st time i turboed this car was with the f23 motor...that didnt last too long but then again i did not have any form of fuel management...then i did the h22 swap and just got on it with out tuning it..(BIG no no) so then i built the h22 block and got it tuned...my numbers werent very high because i had a small turbo...so since then i have upgraded everything ...so hopefully i will see some good numbers
