What kind of cams can i put in my 95 altima GXE (4 Dr) Ka24DE...I want to boost the performance. I have headers, high flow cat, new exhaust. I also opened up the intake to free up a little power and make it Whomp.I am currently replacing upper lower timing gaskets/seals, and both oil pan gaskets. The head is apart so im looking for a little something extra...Got any ideas whether it be cams or anything else..? Thanks
