hi all again,
you've probably seen my project, a mk1 escort with wrx engine and running gear, running around 320bhp (the WRXICO) well i took it round silverstone and it decided to pop a conrod through the block,
im now building a 2.1 forged stroker engine and need a few tourqe numbers, can anyone tell me the tourqes for:-

eagle con rods with arp bolts?
engine halves bolts?
head bolts?

i have read a few different things for all these tourqes and it would be good to get the right ones, any help is appreciated,
thanks very much,
phil.

 

Re the engine halves bolts (case bolts), there was some big thread on nasioc years ago when someone used arp bolts and did some measurements on the bores before/after fitting new studs.

Basically, with the increased torque of the ARP bolts (case bolts), the crank journals end up slightly twisted, so ideally you'd need to line bore the assembled block to get true crank journals.

As far as I'm aware, however, the standard case bolts are fine even up to high hp numbers.
