It depends upon core shift in the head I suspect, also if you reduce the back-pressure on the impeller then the flow will increase. Also there is an oil to water cooler already built in.

If you increase flow than it make work. And your oil to water cooler is exactly why you install an separate oil cooler and guess what, your oil stays at the correct temperature and so does you coolant.

An extra oil cooler is a very good addition for a hard working or extreme temprature envioroment motor.

But the Oil Cooler will not help the Z motor when rapid heat build up occurs where in almost an instant the temp guage shoots up the dial.

The reason for this rapid rise in temp is useually caused by compression gasses getting into the water chamber through the head gasket in the 2 rear cylinders but mostly the passengers side (drivers side here in Oz)

The reason in my case has been bad tune & therefore detonation in this area. Upon motor stripdown the the headgaskets show signs of movement.

The cyl head strengthening & water by pass mods are attempts at alleviating a known problem in extreme use applications.

Nissan has seen fit to use the new rear water manifold & water outlet in the Pathfinder as this vehicle could see extreme conditions of overloading, a condition that is impossible with the Z

Any updates on this kit, are people still using it and recommend it?

Is this the same kit as forged sells, alittle cheaper

I'm installing one right now.

A buddy of mine has this mod but has issues connecting the watertemp sensor connector and the nock sensor connector.
They are just too close by to one another and when putting them on they hit.
Even after removing some meat of the connectors they still won't fitt.
After a surch on google there seem to be no discussion on this matter. Has anyone delt with this issue....??

Take more meat off the connectors, worked for me I think I also had to plug the cam sensor in first or vice versa but it did matter the order that I plugged them in.

Anyone got a tech sheet on how to install this mod? Want to figure out if it's actually do-able with the engine in...

I had this done on my stroker. I have a larger Mishimoto radiator, Forged fans & shroud, a medium sized SETRAB oil cooler and so far am actually running a few degrees warmer (since December in under 80 degree weather) I expect to see good reduction in my 230 coolant temps when the Phoenix summer hits and it is 115+.

its do-able with the engine still in the car, you just need to remove the plenum and perhaps the lower collector to have enough room to work with. Your also going to have to move some cables around and do some slight modifications but its fairly straight forward to an experienced mechanic.

would be interesting to hear what temps you hit when it's warmer. So when you're saying having it done did you have someone else do it for you (engine out or in) or did you do it yourself?

aln

you got an install sheet? It's specifically "slight modifications" that would be interesting

It was part of a build.

Post 338 shows it attached.

thanks so need to take a lot of bits off to fit the pathfinder mod, is the welding an option or required do you know?

I removed the factory oil cooler (and installed a real oil cooler) which is really a coolant warmer and in doing so needed to seal off the passages the coolant was routed to.
