I am currently putting a bigger turbo on my bf mk1 and still stock bottom end, I dont really wanan invest in an atomic bottom end

and was wondering, if I only put a decent set of rods in what sorta power could it handle with stock pistons?

or if I just do rods and pistons?

just dont really wanna put to much more dollers into it, just need piece of mind that the rods wont break, wanna make 450rwkw I am thinking.

If you've got it apart you may aswell do the pistons. Do the oil pump too.

if you do one thing, you SHOULD do the rest 'for piece of mind'

Your better off doing pistons as well if your pushing 450, mind you, these are a bare minimum, there is no real cheap way out of it though, just rods and pistons will set you back a small fortune, theres other things to consider also and it will add up fairly quickly. Take into account labour if your not doing it yourself.

Be prepared for a shock if you want to do it on the cheap side. Let alone properly.
