I wouldn't want to risk it beyond 450 without closed decking it. Liners are just to thin so flex or worst case fail
Completely agree. Pinned block is an option done loads before with good results at higher power levels, but personally if I were doing a big power 2.5 I'd want the closed deck inserts to make it a fully closed deck block.
Thanks On-the-bog and Brownpantsracing. I already have forged internals and running a vf35. I may have to go for a 3 inch exhaust (with sports cat) and an 18g turbo. Hopefully, that will see me with 380 ish bhp and I can save £2k fitting a 6 speed box.
