I switch my old 1991 CRX si engine wit 170,000 miles wit my other 1990 CRX Si engine which had 80,000 miles.. The change went fine ...did it in a couple days but after that i started to drive it. it does not feellike it is going fast at all. do not get my wrong it runs turns on and everything but there is no...you know "pull." Do you guys have any answers on what the problem could by... i am thinkin it is a vaccum.
