Well, I'm happy to admit the internet was right. The stock bottom end couldn't handle the EFR or the drag head.
After an enjoyable night at roll racing, a big misfire developed and 4th cylinder spark plug is doused in oil.
Changed spark plugs & 20km's later, same issue and a misfire. I suspect a piston ring is on it's way out & haven't even bothered with a compression test. A budget rebuild was considered but after hearty chats with Piggaz/Micko, I've decided on the royal treatment. In the next few weeks the motor will be removed & will head overseas for the 2.2L treatment, we are talking Carillo Pro-H rods, CP 9.0:1 pistons w/ 0.200" wrist pins, & a billet crank. The drag head will also get refreshed with solid pivots / 270 procams/ new VCT.
And before anyone tells me my gearbox will explode.....yes, yes it will.
