Mike, I honestly don't know enough about the dynamics of using both your baffle plate and the Cosworth kit. If I were to surmise I would say that the baffle plate that you currently have is more efficient in reducing the amount of foaming oil that the oil pickup receives as the oil is being sloshed around in the upper and lower oil pans. Obviously foaming oil is not a good thing as it contains a lot of air.

The Cosworth kit seems to be designed a little differently. It looks as its intent is to prevent oil from rushing away from the oil pickup and the front of the upper oil pan during high G load instances (acceleration, cornering, etc). The circular cut-outs hidden behind the rubber "doors" allows oil from the rear of the upper oil pan to come back towards the front.

Raj, my experience is only with a non-revup motor as that is all that we have at the shop. With the non-revup an install kit is required. The install kit is essentially a thin spacer that has an extrusion that allows you to mount the baffle. The spacer itself mounts in between the upper and lower oil pans.

This would work fine with a JWT or AAM spacer on a non-revup using the install kit. The nstall must be mounted between the upper oil pan and the AAm or JWT spacer in order for the baffle kit to work correctly.

Here is a picture of the install kit for non-revups...

 

Ahh - I got it now - thanks for the detailed explanation. I thought that "spacer" pictured in the plastic bag was just a flimsy gasket.

 

I snapped two illustrations from the instructions to better help anyone else who still might not understand how the baffle is secured to the motor...

Non-revup with install kit...



Revup, secured using a piece that Cosworth refers to as a baffle plate that is already installed on a factory motor...

 

the early years had no baffle plate that sits around the pickup. The newer models had a baffle plate and hence the mounting points for this plate is re-used for the cosworth kit.

Item 18 in the below image.

 

i'm a little confused what exactly is this for? can this help reduce oil consumption?

 

Read the blurp on the page linked in the first post.

 

Anyone know what the part number for item 18 is or what it is a part of? I'm looking to purchase it and I can't find it in any schematics on courtesy parts, etc.

 

Doesn't appear to be on nissan fast either. I suspect it is supplied with the oil pan assembly

 

^Yeah, no one on EBay can confirm. Upper or lower assy, though? So annnoying...

 

I feel like this would reduce cavitation and keep everything settled in the pan rather than the under the crank/block, but my assumptions could be totally wrong. Definitely wouldn't hurt.

 

If you buy the cosworth kit then you don't need the oem baffle as the instructions ask u to remove it I believe. Might be the easier option then to find the plate at a wrecker

 

Found one.

Just for the sake of accuracy, the baffle actually secures the oil control baffle, so it is required on the rev up engines. I just don't want to pay another 100 dollars for it.

Thanks for the help!

 

cool.. just make sure you put thread lock on the little screws as per manual

 

Kwame, your pictures are not linking. Can you restore? Thanks

 

Definitely kwame, could you restore those pictures?

 

I think I deleted them by mistake and no longer have them on my computer. I'll be getting my assembled motor back in a few days to a week. When I get it I'll see if I can snap some pictures of the kit installed.

 

I have this baffle plate installed on my RevUp in addition to the AAM spacer. The Cosworth baffle plate is wedged and bolted in between the upper oil pan and the lower baffle plate. The upper oil pan ramps up toward the back causing oil to make huge shifts under hard driving conditions and can cause the oil pick up to become exposed. Since any of the aftermarket oil pan spacers allow an additional qt of oil, you essentially add even more protection to your engine. I just replaced my rev up (one of the lucky ones who had an oil consumption problem and developed a rod knock at 80k). I made sure I took extra precaution when I installed my new rev up. The Cosworth baffle plate install is so easy you only need a 7mm, 10mm, 12mm socket, ratchet, silicone sealant and thread lock (for the baffle plate hex screws. The non rev up has a different oem lower baffle, but the same lower oil pan, hence the reason the install kit is needed. Cosworth states all 03-04, but the majority of the US spec 05 Zs had the non rev up as well. It's well worth the 70 some odd dollars for some extra protection. Hope this helps guys.
