KL-ZE Building

07-19-2009, 11:52 AM
Hi.I could need some help with my mazda mx-6 KL-ZE project.Sorry for my english skills :(

Im rebuilting my engine+adding turbo and this is what i have already purchased.

Forged pistons(CP)+rods(Grover)
Tri metal bearings(clevite)
KL-ZE computer+chip from extremethings (old one was a piece of shit :D )
Lifters,valves+eibach valve springs

Forged crankshaft if i found one :( anyone knows where i could get one ?

Can KL-ZE camshafts take about 300hp or more ? if not,where can i get better ones that works great with forged pistons ?

Idea was to built this engine to last over 300-400 horsies

what else do i need to make my klze to be a bad ass...:tongue:

port and polish. big horsepower gain for the KLZE

^^^Port and polish will not get you much of a gain, especially if the motor is going to be boosted. The amount of work required is not worth the effort, again, especially since the motor is to be boosted.

As far as the forged crank, all Mazda K series crankshafts are forged. The KL crank has been used in a twin turbo build which ended up making 800+ horsepower.

Also, pitch the Extremethings and get MegaSquirt. This will allow you to tune the car yourself to run as much boost as you want since your built motor will be able to handle it. The extremethings ecu won't let you run more than about 4 psi successfully.

Interprep or Colt for cams.
