Folks 'round these parts are used to the OBX and Tsudo headers...lots cheaper.
I'm lucky to sell one of these a year.
^^^ Why so cheap?
Not alot of power to be tapped into NA with these engine without serious mods to support it.
Just finished installing the headers. Was a workout to take off the old stock stuff and put in the new ones. Did the non-fouler fix, so hopefully my check engine light won't come on. Didn't notice a HUGE improvement in HP. I was expecting way more zooom, zooom!!!!!! (outie)
There isn't going to be. In fact, you'll lose low end torque with a long tube header but gain top end power. That's why I went the short header route. With gutting the cat it's basically the same, but it creates more back pressure so you don't lose the low end torque. If you look at the stock manifold you'll see the is on outlet that is really crempt. The header fixes that and that's were you get the power gain. Maybe 3hp on a N/A car. On a N/A car, the best bang for you buck is a C/A intake, short shifter and a 7lb flywheel. You'd be surprised at the amount of power you get by dropping 15 lbs off the rotating assembly. If you can get a MP3 ecu or buy a stand alone that would really help.
You actually have it backwards.
4-1 header loses torque and provides better mid-top end range power
(Gains are more noticeable in the Mid-top end range)
4-2-1 header Provides better low-mid range power.
(Gains are more noticeable in the Mid-low end range)
You know, you may be right. It's been along time.
hi everyone
just question, I heard that mazda 626 intake manifold increase performance
on mazda mp3 or protege ES, My father have this intake.
work this on my mp3?
