Just finished putting togeather my rb25det engine after a top end rebuild. After starting it up there has been a lot of smoke comming out the rear whitch I believe is due to a bit of coolant in the bottome of the engine from when the head gasket blew before the rebuild. After taking it for a test drive it has no power at all I seriously believe a Mazda 121 could beat it. If anyone has any idea on what I could do it would be a huge help.
Cheers Damo
