hey everyone just stumbled onto this site. Im from ionia michigan in between grand rapids and lansing. I just bought my 4th gtp since 97. This one has quite the motor.. Bought it from a buddy that just lost interest couldnt pass it up. ill find out hp and get the final tune done on wednesday if all goes good!!!

well not a good day folks. just got back from zzp in grand rapids. found out that cylinders 3 and 6 are flat lines. tried changing coil packs and that wasnt it did a compression test on the cylinders and all but those 2 were good. so matt thinks its something in my heads so those will be coming off and back to the machine shop hopefully its just a bad valve seat and nothing major. we did a borescope and atleast we know its not piston related! On a good note they made half a pull and it made 210 on 4 cylinders lol so i know its got potential. ill keep you guys updated.
 


found out the problem last night took the heads off and th evlave guides were machined down to far causing the stem of the intake valve to push through to far and made for sloppy play causing the valve stem to walk all over the place.. im hoping my head guy can fix me up quick!!
