I just saw a post about someone upgrading there valve springs to Mitsu EVO springs or something. Does anyone have any input? I tried the search button but what a worthless thing that was!

I used a set of Comp Cams FORD 4.6 springs and seats. I did need to turn the seats down to fit in the head.

+1 on the search engine. It is fairly useless Confused

I'm also interested in valve springs - but - I've got to chime in on the search function!

This morning I searched, "USA superpump" looking for dieselmekens thread and got nothing.
Then I sifted and found the title: "Superpump builder in USA".
Useless.

I used Comp Cams Ford Modular springs as well I ended up getting a set of 24 for a good price. I would be willing to sell the other 12 springs. For a good price.

Did you only do the exhaust?

Yes I will be doing them over Christmas week. The intake springs really don't need to be done the exhaust springs have a descending piston and back pressure to compensate for. Factory springs are only 40-45 lbs new that is just to little. Think about it if you run 30 psi and have a little more then a 1-1 pressure ratio. You will float your springs with less then 10 lbs to effectively close and keep your valves closed.

As far as you know they are drop in? What about intake then. You have the same amount of presssure on them. Why not do them all?

Intake has the pressure of the piston moving up increasing the pressure in the cylinder not creating a void like after the exhaust stroke. You also want to keep any exhaust from leaking back into the cylinder creating a hotter air mixture. No need to increase my intake springs I won't be revving over 6000 rpm. Also the less the pressure on the valve train the less hp loss in the engine.

The valve springs are not quite drop in as they require different valve retainers and a valve seats to locate the spring correctly. The stock valve seat is a little large on the diameter of the inside of the spring. The difference is less then .020 because of a tab on the end of the springs. You can grind the pin and chamfer the inside of the bottom of the spring and use the stock spring seat.

Anyone know of a valve spring readily available outside the US which would be a good upgrade for an OM605?

CDI engine springs are drop in solution
M104 and M119 have much much stronguer springs that can be dropped in.
