To make an ej205 like an ej207 you would need to:

1. Change the block to a semi closed deck.
2. Change the crank to a forged double drilled unit.
3. Change the rods to forged rods.
4. Port the heads
5. Chang the valves to sodium filled.
6. Weld up the Combustion chambers and remil to 49cc
7. Change the headgaskets
8. Change the cams and cam buckets to the no shim design.
9. CHang the oil pump
10. Change the water pump.
11. Mill heads to accept AVCS and sensors
12. Obtain correct cam belt and cam wheels.
13. Change intake manifold to STI
14. WHY am I typing all this out?
15. I have no idea
16. I guess I am bored.
17. Sell 205
18. Buy 207.
19. DONE.
