Hi,

I am in process of putting a new cam in my 5K now as we speak just called it quits for the night.

 

I will post the cam sheet I got with my cam that I had make all its power between 2000RPM and 5000RPM as it is my daily street driver.

 

I have a few cam grinds on my bench here that will make a 3K or any K motor go hard and yes upwards of 10,000RPM cams so ill post them here soon.

It says it down the bottom, 5K

Ok i`ve only skim read this thread so shoot me if I'm wrong but the compression heights on 4age pistons is way to low to consider using and as to why anyone would use such a damn heavy piston is beyond me same goes for the rods why fit a heavy rod if the standard ones do the job?i really don't understand the point of adding to the reciprocating mass then reving it and then proceed to blow the maincaps out of the bottom of the engine.

Standard rods over here in race spec 4k engines ie 4mm overbored forged pistons will run endurance races(multiple one hour races) without giving trouble,if it aint broke don't fix it! :P

hm I'm slightly confuse as to which head to use on my motor now, its got a stage 5 cam, 4age pistons, not sure which types, shaved block, quad throttle bodies, bottom end all balanced, it used to be ke25 racers 5k, and he used a 3k head on it, to get a comp ratio of 14.5:1, when i got it it came with a 5k head, i want to build it to the same specs but now i have been offered a bigport head as well as a 3k head and unsure which to use, both will be shaved and ported aswell

 

ok i just took a look at the head difference topic and found out that it is not actually a 5k head i have but a mildport k head :)
