Can anyone recommend a shop to port and polish my head? I'm in the Mid West and everyone seems to be afraid of Nissans. Also, what is the largest exaust pipe I can put under my car? And one more, 4-2-1 headers or 4-1?
Low end. It'll never go 200 mph, but I want it to get to 80 fast!
well sry i aint tryin to race my car on no track, maybe stoplight to stoplight for these punks round here who think there cavi is fast. and looks, and 1 more question for someone who knows, after i buy headers should i get that header wrap stuff? i was readin that it obviously decreases heat under hood, does it add any power?
A good 4-2-1 header is always the way to go for the KA24 on the street, so that you can take advantage of the great low to mid range power. I would only recommend a port & polish if you have done all the other head parts like Jim Wolf Technology S1 Cams, Springs, and Retainers or Colt Stage 2 Cams and Springs. A multi-angle valve job will give you a better bang for the buck than a full port and polish. Besides, in an N/A application you really need to be running at least 11:1 compression in order to take advantage of the higher flow which a good P&P job would provide. But if you really want a really good job done expect to pay ~$2K plus the cost of the 1mm larger valves that Ferrea sells. The largest pipe for a N/A car would be 2 1/4". Also make sure the exhaust has a resonator in the mid pipe or else the exhaust sound gets annoying.

Just get the ceramic coated headers instead of wrapping them.

but i aint got much money i got a fiancee and a kid on da way, and i can get OBX stainless 4-2-1 headers for 200 shipped, then the wrap is only 35.00, thats why im gon do this. cuz off of ebay i can get a whole exhaust from headers to high flow cat to bolt on stainless cat back for 500
any links for any of these headers? im thinking on getting some...any good sugestions either? best deals? can you really feel the difference too? thanks.
