If they were forged, why do people buy aftermarket forged pistons?

 

[DAN00H]

stock GTR pistions are NOT forged, but if your limit is 450hp they will stand that if your car is tuned properly (i.e. stave off detionation!!!) I am currently making 480hp on my stock engine....

 

[cypher]

so assuming that its all done properly (which is the plan) they will be ok!?

 

[DaleHarrison]

GTR pistions will (as said above be OK for that) but get a price comparison between a new set of GTR pistions and a set of aftermarket forged items, there might not be a whole load of difference....

 

[T.F.S.]

you can get forged items for less than £500, block would need rebore though!!!

 

[cypher]

umm, why new, y cant i just get some from car that has been upgraded?
just theres no point me going forged if tis gonna cost 3x the price!

 

[T.F.S.]

well have a look at the quality of the pistons on the GTR....i would use second hand ones unless they had x-ray pics with them TBH

have a browse through the rebuild thread on skylineowners.com in the projects section for a more detailed explaination..

ps the new ones were actually cheaper!

You can use RB26DET rods with RB25 pistons and crank, but if you want to use RB26 pistons, you also need to change RB25 crank to RB26 crank. Do a quick search about this, its a common thing that been discussed a few times now on different skyline forums.
