It's a 98.5. has any one had problems of motor durability due to using the 2.5 heads. Is the compresion ratio to much for the stock head gaskets? Id like to know the specs on each of the 2 heads. like the intake/exhaust valve diameter, and the intake port diameter. Befor I do any of this I have to replace the seized cylinder. This will also inclued new cylinder sleves. It wont be that hard because i have access to the right tools. ill just have to pay for the parts (Not to mention all the bolt on to go with it). Also, what about air/fuel delivery? I have read a bunch of posts about improper air fuel management. Is the apexi the correct road to fixing this? Will the 2.5SVT PCM handle it? I know I ask alot of questions I'm just really excited.anything will help, id like to get started asap
