3406E CAT guru's-what piston do I need??

generaly the pistons are the same(ratio 16.25) what changes is the form of the crown. ill give you some numbers 16.25 the crown 149-5566 the skirt 130-0241.
E and early c15 16.6:1 the crown 180-7352 the skirt 132-6663 (14.6)
335-410hp 16.25:1 crown 135-2837 the skirt 130-0241
435-475hp 16.25:1 crown 7c2888 the skirt 130-0241

I think you also need to chnage the cam, the liner is the same . i hope i helped by giving these numbers or you can search them up yourself. i think if you put less ratio with pressure you can get more hp

 

5EK02306 the following parts will allow the 550 hp

0r8321 piston pack
0r8452 camshaft
0r7205 turbo
0r4893 injector

These are Cat reman numbers, They are from a older rerate list, the numbers will change up to newer ones when ordered.

That would allow the 550hp 2100 1708132 flash file

 

DDS,I'm trying to get in direct contact with you somehow about an engine combo for my W900.I'm new here if you know a way please contact me.Thanks.

 

DDS,

Would this cam be the same or close to one for a 475hp 2ws engine?
Do you know what the compression ratio for these pistons?

Are they two piece?

Thanks

 

Usually if you replace o-rings on one cylinder you will need to do them all or another one will leak almost straight away. It would be easier to do the whole lot at once anyway, once you've got the head and sump off and one liner out its not much more trouble to pull the others.
You can try Bars leak or any other radiator addative to stop the leak if you need to get a few more months out of it. With leaking liner o-rings I have seen about a 70% success rate using addative to stop the leak but... BE WARNED.. this is a tempoary solution only and may cause other issue if you use too much addative. BTW I dont recomend this stuff I'm just saying its and available option.

 

The camshaft in a 2ws is a 0r8813, also used in the 7cz 600 hp. The 1177059 piston in that pack is a two piece steel with 16.25 to 1 ratio.

If your going to spend the money on a cam, I would buy the marine cam.

 

DDS,would that 2WS cam be similar to what is in my MM1?I am looking to get one of the marine cams and when I get one it will be for sale.Does anyone know who might have a marine cam for a 15.8 3406E to sell?I am also looking for a set of injectors.I also need to fing someone that can do some ECM work.Any help woould be appreciated.

 

Which injectors do you want, i have a set of 58's i would sell, also a 7cz cam.

thanks Jeff
