One of the most underrated nitro engines currently available. It likes to run hot. Run a 2027 PCR pipe with a header off a OFNA 086 pipe+ 1.1 springs and aluminium shoes, this will help with the bottom end. Just buy the standard 8 port the older style, not the newer ones with sliver heads. You want the ones with either Black or Purple head. Also follow the mid range needle settings from Engine Lounge under Sticky.

For further information check out the OFNA forum, under Engine Lounge, hyper 8 port engines. Look for posts by Rob B aka Nitrohouse.

I had one I leaned bottom so much that was pinging hard, the head bolts of the engine came loose (did this a few times) and she's still kicking. One tough engine.

Hope this helps
