no they use square ports, thats why alot of guys with mx3s swap over to the millinia intakes, cause you dont loose any power (it just changes where teh torque is) and they fit without any modifications in the mx3. To use the the straight neck in the mx3 you have to relocate the battery to the rear of the car, then cut and weld the TB. to much of a pain for a slight change in torque.

SHIT! i forgot to mention cams, thanks silverprobegt! Yea your gonna want to get a set of kl31 cams they will provide better low end torque and about 12 ponies is what i've been seeing. you can get them off ebay for a decent price, usually around 150 for a set.

Also GREAT that you mentioned the tranny cooler, Mazda's Autos SUCK BALLZ not gonna lie, the tranny cooler GREATLY increases the life of the transmission.

For ecu upgrades, I THINK i'm not sure but you can use an ecu called the KL66 ecu. Its was the OBDII ecu for the klze motors. Though i think it doesnt utilize the je50 or kl02 mafs it think it uses a vaf, which you can get off a mazda rx7 2nd gen.


Yea thats all i can think of. as of right now besides little stuff like filling your motor mounts and little stuff like boring the tb and stuff

Silverprobegt you should come out to a moca meet one day, or atleast meet up sometime, I like seeing other K series cars
