1. So can I use one of these headgaskets? D16Y8 - D16Z6, D16Y8 2 - layer, D17A2 http://www.zealautowerks.com/dseries.html
2. Could I still use 87octane?
3. Just looking for a little more power, but how much I'd like to know?
4. Would this be a bad idea if I turbo it with T3/T4 turbo my max is 8psi?
5. Is the d15b7 a interference engine?
The engine is out of the car and apart I haven't fixed it yet, it was burning oil from worn rings and bad seals. |
1- Yes, they will work.
2- Yes, this should still be fine.
3- You are moving .5 points of compression. Not really a big jump, and you will probably not notice the difference.
4- Not if you get it tuned.
5- YES
You could put in PM7 or P29 pistons, and bump your compression up over 10:1 also.
