gsr block wit 87mm piston??? the ori bore is 81mm. if rebore till 87mm the block sure koyak dy. max also 83mm - tx3 piston.... unless someone has done this:confused::confused::confused::confused: 82mm oversize is gud enuf dy.

mikanaem, if u wanna change block, then i wud suggest gettin the 4g93 GDI block wit its stock stroker kit cuz i heard tht u cn get a cr of 11.0++(hope the sifu's out there cn rectify if this is true or false) tht is if u wanna play NA...other thn tht change to bigger injectors, open pod air filter, aftermarket headers, iridium plugs, lightened crank pulley, adjustable cam pulley, walbro fuel pump, fuel regulator, bigger capacity fuel rail n put a mivec sticker on ur windshield:biggrin::biggrin:.. n if u really have the budget, go 4 jun cams, port n polish, acl bearings, bigger tb, standalone ecu n sum semi slick tyres. just my 2 cents

bro... try 1.8 block to ur 1.6 mivec.. big big different..... remember to get a gud racing clutch to hold the power...... piston i recommend to use back ori mivec high compression piston is enough... when u do this mod, better use higher cc injector(gsr 390cc is enough) and thicker metal gasket (ppl tell me to use 1.2mm or 1.5mm better) then u can feel big different from 1.6...... dun forget to get a adjustable fuel regulator, bigger fuel pump and redo ur piping :burnout: happy modding mivec
