u do know that the forum d-series.org under the naturally aspirated section has all the parts number and info you need about using jdm d15 and so forth... u may wanna browse there and see if you can gather more info about other peeps who have done this swap and what parts you will need to make it run proper! I agree with others here, do it right or don't do it at all! that being said, g/l with build!
