so, ive been wondering why more people dont go for 2.8L capacity since the only difference between a forged 2.6 build and a 2.8 is a crank that costs a measly 800 quid more than the std one from the place in the uk that does the one for the hks kit (keep forgetting the name)

or am i missing something here...

Pistons, And sometimes rods

I was under the impression that longer rods were necessary.

If this is not the case...I'm going to want to shoot myself, as I replaced my crank last year and would have bought a stroker crank in a second if it would have worked with my stock rods!!!

I got a HKS step 3 with the engine builder and its, Rods, Pistons and crank

I'm sure I have seen kits with just the crank and pistons. The pistons have a different pin and sleave height to measure up with the increase in stroke.

i.e the pins go a little higher up in the piston so the compression remains the same with the longer stroke, and the increase is at the bottom of the stroke.

Farndon in Coventry.

Longer? I think shorter.
They compensate the longer stroke by using shorter rods. The rod stroke ratio stays slightly over 1.5 so that's fine.

 

[souroull]

right, say the rods and pistons are a bit different. does that mean more expensive aswell?

i wasnt referring to already built motors per-se, but if you're replacing pistons and rods already for a 2.6 build, and the farndon (thanks jags) crank (used by hks stroker kits) is only 800 quid more... then why not go for the stroker instead.

are the pistons and/or rods required for strokers something special that would make them unobtainable? (like price or design/availability limitations)

thanks again

Are there any manufacturer, who offers shorter rods to go with 2.8 crankshaft?
Or is it more common to use normal size rods with stroker pistons?

Arrow rods will make custome length rods and they aren't all that expensive. Then you could use off the shelf Wiseco or similar pistons
