So I just stopped by my local machine shop to see what the progress was on my 5s block and they said that the pistons were trash, three bearings were gone and scuffed the crank. And they said that they were going to have to overbore .030 which is fine with me, cause I wanted forged pistons and rods eventually anyways. If I do end up boring, am I gonna have to invest in a piggyback or will my 5sfte be okay with just the BTM I have. MOD LIST JDM CT26 7mge 315cc fuel injectors 3
