screw it just by the dart tall deck 2.1l(actually works out to be 2.3~l) built block we have one here in augusta in a buddys hatch...no problem with power and the displacement issue is not a problem...just lots of $$$$$...he's sunk over 9 grand so far....precision 67(custom backhousing) ,1600cc injectors,fullrace manifold,type-r head built by jg engine dynamics,hondata full setup with wide band,etc...numbers with the precision 61 were 450~500 low boost.....but now it should be 800-900~ as promised...not sure on that but thats the best guess so far...btw call jg engine dynamics...the owner says oil squirters are a waste of time/money.....just slows down the rotating mass......they know what they are talking about.....good luck with the swap/install...hope you make good numbers
