Dears,
I have problem with head block, it's always opening after drag race (2 runs or 3 runs), I changed the head bolts from RB25DET ARP bolts to RB26DET ARP bolts but still the same, The Head block is removed from the block after 2 runs or 3 runs, also I changed the Head but still the same.
Please see the following is my car engine info:
Horse Power: 1380
RB26 Head with RB30 Block
Cometic Head Gasket Kit – RB26DET - Thickness: 1.3m
RB30 CP Pistons 87m with 8.0 compression ratio
250HP Nitrous
RB26 ARP Head bolts (I tighted the head with more torque)
I don't know what to do?????
Please this is for those who reached 1300HP and above.
Thanks!
