Try this link it's from the OFNA message board. I posted as 1badhyper7 to start some discussions on this and to get help.
If someone can help determine what the cause of the problems I am having, I will gladly recind my statement and start another postive thread. But until then, I shall hold my ground and firmly state "don't buy this engine"!!
I know and have talked to three guys who have problems. 3 out of three all had problems and 2 out of the three have either sold them on e-bay or sent them back to Nitrohouse where they purchased them.
