wakeabby14 Posted August 28, 2017 Posted August 28, 2017 (edited) Looking at running around 280BHP on a TD04 (19-20PSI) , of course i already know about fueling, mapping ect just all the extra goodies for the main build. I wasn't planning on forging however my bottom end went this morning so no other choice really apart from a new engine but would rather forge it! Also normal OEM head gasket or 1.4mm athena gasket? Also do i need valves or am i good with stock? Let me know guys! Cheers Edited August 28, 2017 by wakeabby14 Quote
gorganl2000 Posted August 28, 2017 Posted August 28, 2017 what exactly went on your bottom end? Quote

maddox710 Posted August 28, 2017 Posted August 28, 2017 Would of thought the block still have damage even if it didn't go through. Il be very surprised if it hasn't Quote

AdamB Posted August 28, 2017 Posted August 28, 2017 Buying a second hand block will be cheaper than having a machine shop re hone it Still need to hone a block when fitting forged pistons anyway. You'll need to have the valves measured to determine whether they need replacing. Measure the ID of valve guide, and OD of valve, this will give the oil clearance. If it's out of tolerance, replace both. Quote

I recently just had my head skimmed and rebuilt with new stem seals and all the valves reseating my head gasket went so got it done while it was off. block is getting done at my mates machine shop Edited August 28, 2017 by wakeabby14 Quote
