Hey guys I've been reading on here for a while and working on my 89 f350 its getting a ppumped 12v and zf5. I wanted to show off my project and get input from you guys the motor is built and I'm swapping a cab from a 94 now. Im looking to run compound turbos thinking about ED right now but want input on other people to talk to as I'm fairly new to the diesel performance scene and there are lots of companies i know little about. So ill be posting some pics as i go and would love input positive or not. I'm not a computer guy so ill get pics up as soon as i figure it out.

Here are some pics of the head I ported it, ceramic coated the face of the intake valve (just because there was some left from the pistons pics of them to come), and did the valve job myself. The o-rings, decking, and spring pocket cutting were done locally. Comp cam springs.

These are my pistons Im using the original ones trying to keep the budget under control. My friend cut the bowls on a lathe and I coated the tops and skirts using Cerakote. My friend lightened the wrist pins as well.

What kind of numbers are you shooting for?

 

[fummins97]

you've got a great start! I've done two swaps on 97's, but haven't done compounds. Only thing I do know is that you will probably have to eliminate the heater box. There are other options for that available from jegs or summit though. Keep the pictures coming!

 

[WUnderwood]

you really think the Cerakote on the tops and sides of your pistons is going to last?

 

[Nor'Easter]

You will be building your own set of compounds. No way a box kit for a 2nd gen engine will fit in an OBS, been there. Good news is it's pretty easy if you are good with angles.

I'm going to find out if the cerakote holds up, I think the prep is most important, so far i dropped a piston on the edge of the top and the stuff didn't come off. I also did a junk piston and hit it with the torch I'm impressed so far. I'm sure the skirt coating will wear away with time but thats partly why its there.

horsepower goal as much as i can get 700-800 maybe
cam is 184/215 110lsa on a 105 int center (pics of degreeing the cam to come)

To each his own... What I don't understand is the perceived benefit of cerakote vs other proven coatings for this application.

 

[Win slow]

Degreeing the cam. I'd like thoughts on intake centerlines and lobe seperations from you guys, don't just comment that i should be running hamilton please.

 

[Win slow]

Thanks for the good pic Nor'easter that looks real good, I'll be doing something similar I hope.

 

[Shainer]

Can you speak towards your decision of the cerakote? I personally am not knocking you but that seems to be a coating that may not be amicable for the application. I've searched the web for this application all I've found is exhaust manifolds/headers. The application seems no different than many of the high heat paints you can get in a spray can. Personally I don't trust that at all on engine internals. I would wipe every bit of that off with lacquer thinner.

This was one of the threads I saw that put me in this direction. I don't think there are many thinners that would wipe the stuff off it must be blasted off.

How do you think the pros do it?

I'm not saying polydyn is useing cerakote but it is a similar process. Note to all those thinking about doing it your self it was kind of a pain its worth paying a pro to do it unless you like doing everything yourself.

 

[longhorn859]

Cerakote has been effectively used on pistons with great results for a while now.

Here are more pics, The injection pump was built locally with my parts, 13mm p&b, 160 pump cam was reground to match a 180 pump cam, and afc mods of course. The pump was benched to 670cc. My timing pin is home made due to cam timing, 24v lifters.

Thanks for the vote of confidence on the piston coating longhorn. The piston coating is the least of my worries, I was expecting more comments as I am unsure how everything is going to work out. I am not claiming to be an expert this is my first performance diesel build. That being said it wont hurt my feelings to hear that something I'm doing isn't going to work, not that I will listen:lolly:

 

[Nor'Easter]

Any photos of the truck?

 

[Win slow]

Sorry about the crappy pics I only took some with my crappy cell phone, I didn't plan on posting any of this originally. Here is the truck I cant find any pics all together sorry. I know the crossmember is a little sloppy but im not a fabricator.
