Con rods
I'm on a rebuild of my engine that suffered crank failure. I have all the parts for the rebuild (except the turbo) but on taking my con rods out one of them has some of the shell welded to it so I need a new rod! I'm only building this back up to standard spec so I only want standard rods.
The thing is I can get wrx rods but sti ones are not available to me at the moment, so I was wondering if it was ok to use them?
Is there any difference in using the wrx rods in my 96 sti????
Or could I get another rod with the same number on it from one engine and get the cap with the same number from different engine & match them up?

No difference, thats the big weak spot on classics and why you shouldnt run more than about 350bhp, they normally just snap and put a big hole in your block

I meant weight difference between wrx and sti rods.
I'm building this back to sti standard spec except for an AFP turbo, decat pipe and filter so shouldn't be more than 290 bhp?
I will be remapping but then I will prob only get maybe another 40 from that? So standard rods will be fine?

(unless they're prenumbered by the manufacturer)
