a friend of mine has a ZC with the oem 4-1 header. he also has a 4-2-1 from the Z6.
will we see any difference if we put the Z6 one?

i was afraid about that,too but they say "no"
a friend of mine is buildng a b20 and did the same thing. we will see

what's your opinion about that?

you need lots of money for b16b cams. valvetrain upgrade and pistons with higher compression

anyone knows if there is any difference between 1st gen.(89-91) b16a cams and 2nd gen.?

i think the caliper's serial number is PFKL212907. it must be the same with 98-01 integra's

R888 are dangerous not only when it rains, but even if one side of the car, contacts dirt and generally, surfaces with different grip levels

R1R is also wider than others. it's more....."square". profile is not exactly 50,too. i could say it's somewhere between 50-55!!!! the ef9 seems taller with R1Rs,hahaha

a friend of mine has the following set up on his EK4:
REAR: calipers and rotors from ep2 civic with ferodo pads
FRONT: crv calipers and rover mg rotors with carbotech pads
MASTER CYLINDER: from crv

the carbotech pads and the master cylinder,are the best upgrades of this set up

2 weeks ago i bought R1Rs for my ef9. awesome tires. the grip is very high. braking has also improved.
steering is a little heavier, but with a very nice feel.
i think R888,is extreme solution for road use but better for tracks and R1R more...."sensible" for every day use
