Alright, so I nuked my TT HG and went with the BL 2.5mm. My question is this...how is it going to effect timing? Do I need to dial down a few degrees or what? Also, is there anything else that would need to be done?
Did you over heat the engine? How many miles on the block? If there is alot and you have not change your valve stem seals yet, this is a good time to do it. Also do a compression check just to make sure you rings and valves are still good.
