I'm using wossner's, HAndy and JP do too but I've heard a few people just the standard piston machined down to lower the comp ratio.

[rs250nut]

I very much doubt anyone hiding much on here, not sure what the norm is but if you look in the projects section I think there are a few f7 builds going on.

[Tutuur]

just buy my engine and be done with it :D

[JP Racing]

As oli points out I run wossner pistons but I do have a set of std pistons which have been machined to a lower cr :) was going to build a second engine for a clio I have but don't have the time :)

[JP Racing]

Oh and just buy tutuur's engine he's keen to sell :D;)

how are the pec rods i saw they had some problems in the past do they need work to fit or the sizes is are fine

[danielmk323]

Guys are the f7p f7r and f4r have the same rods ?

[Tutuur]

that's correct

[James5]

Don't forget if you use f4r rods you will need to use f4r bearing's or f9q bearing's:agree:

I did post a pic sometime back of the comparison of F7p, F4r and K-tec H rods for F7p/r next to each other but I can't find pic's:crap:

[danielmk323]

Can someone give more info what this means?

I'm asking since all forged conrods are sold as F4R/F7R/F7P compatible. What bearing to use then?
