    I beam are a touch heavier, but a stronger construction.
     
  3. What's the price on these in sterling mate
     
  4. ~310 + shipping and they come with arp bolts! :smile:
     
  5. That's not too bad then
     
  6. never heard of any experienced tuner using PEC rods on the F4R engine around here :tongueout:
     
  7. Plenty have used them without issue but no one's ever even heard of FCP around here... 1-1 :wink:

    I've got Wossner pistons and PEC I beam rods, engine has had it's first run up to temperature and no strange noises for me so far.

    I went I beam for the extra strength and doubt the weight makes a huge difference.
     
  9. The Woessner pistons are fine. talked about the Woessner rods making a strange noise :smile:

    The FCP rods have been used on the 16vampir (1000hp), several RS4 + RS6 rebuilds and ofc in some Megs around here without problems yet
