I've had it for over 1 1/2 years and it's been a great engine, it keeps up with anything on the track and get's great runtimes.

As for stock or modified, it's using a standard plug and i've slightly messed with the ports on the sleeve....So i guess you'd call it "modded" LOL

I'd recommend the engine to anyone wanting a good low cost performance engine...

Sorry for the thread jack
