[svanh1993]

hey guys stuck on getting a set of pistons with a full floating gudgeon pin for my engine build has to be 19mm pin and have circlips both ends cant seem to find anything that will work
standard bore piston measures 80.1mm stock bore of 81mm standard stroke option on forged rods with brass bushing on smallend
has any one got a part number of any sort to lead me in the right direction
thanks in advanced guys

I used cp pistons. 20 thou over. 19mm pins is std

I got mine through spool with rods i unfortunatly didnt take note of the batch number but the guy from spool is very helpfull conatact him

yeah i have a set of rods both are 133.5mm centre stroke was around 90mm when I measured one rod is 21mm pin was going to go Honda pistons but I thought its too much stuffing around so I got my self a set of 19mm standard pin size was hoping to run the standard piston with them for time being while I am getting my other head built but then today I realised its a press fit gudgeon pin and not a floating one how much will a set of cp forgies set me back ?

more goodies I'm yet to get
260/270 cams 10mm lift
stiffer valve springs maybe tomei with titanium caps
super tech valves
gasflowed head with a mild port job and polish

block has been checked out and is brilliant bore is 100% no ridge marks on the sleeves
bore is standard 81mm can still see the light cross hone marks in the sleeves pistons were great no slap at all crank was checked and all in tolerance so had a set of standard king bearings put in oil pump was great still so that was cleaned out and checked out and re sealed off .
new water pump was put on this engine was very well looked after was very clean inside head barely had any oil bake marks aswell as in behind the oil pump
rods are a set of maxispeeding rods with arp cap bolts very beefy to the standard rods have taken many photos of what I been doing
arp head studs from the 3sgte studs
mls head gasket
new gaskets all round except not doing valve stem seals for the head as my other head will be getting built once I have all the parts

ecu wise id love to go evo6 ecu for the satria instead of aftermarket to tune for the cams ofcoarse
atm 565cc injectors but will be going bigger once I go gt3076 all of that should go fairly well I think every bit has a job any how

between 4 and 800 depending on how badly you need them and how hard you look.

and looks like you lucked out look what i found in my build photos

 

[khubner1]

also if your going to run head stud heres the arp part number 203-4204

 

[khubner1]

i know one of the boys here offered to get some pin lock grooves cut into the pistons which would let you run a floating pin.
