RJM GTR Intake Lower Manifold...oh yes!

Alstann · 04-22-2016, 12:26 AM

Phew! Been a while since I've posted something on here, but I just got a super cool part I wanted to share.

Yes, I have one of the RJM GTR lower adapters, and dayum, it is sexy. Bobby and the guys over at RJM did some great work here. Been hard at work, but hopefully I can get it together, and install it next week. I don't have a dyno session scheduled, but I'm trying to see if this is something that I could dyno the before and after in the same day, since it'll take a while to install everything. But, for now, some pics of the gloriousness:

These are the billet balance pipe adapters - these just run a high pressure AN fitting hose from each side of the GTR oem manifold, instead of the OEM balance pipe, which won't clear the VVEL motors. Also, RJM gives you a low-profile oil cap, which will let it clear the GTR manifold.

Super excited to finally have a part like this. GTM was taking too long.

I'll keep you all posted in how the install and everything goes, but this is seriously a nice piece of kit! I'm not sure what gains to expect, but my car is a pretty good platform to see the gains - I just have a full exhaust, stock intake, no tune. We shall see.

Reserved for further thoughts, install and pictures.

nice man!

Let us know if the GTR valve cover will work and if the OEM strut tower bar will clear the hood as well.

Will this be an N/A application. What mods do you already have? thanks for sharing.

Subbed!

Im also wondering if this is for a NA application? If so i think he might be very disappointed with the results, but who knows. I hope it makes power

Zbrah · 04-24-2016, 03:59 AM

any updates?

Landoz · 04-24-2016, 07:24 PM

Just make sure you do a before and after hope you get some gains !

I wish it didn't look like that... Looks like it was run on THE fastest setting

True but you will never see it. I am more worried about the insides of the runners since thats where it counts. Im really surprised they didn't smooth them out.

Yeah, the inside is key.

This is what my engineer said (granted, he worked on NASCAR teams, so his perspective is a bit skewed)

Sorry if this is shítting on your parade OP!!!

I don't mean to be a downer or an áss.

Please carry on with the parade

370Z JT · 04-24-2016, 11:40 PM

Youre right. On second look, inside doesn't look smooth at all.

This was my first impression of this manifold also, the roughness of the runners. In one respect it's not a wet flow. This would play havoc and cause fuel puddling. Part of the reason why a carburetor engine wants smooth runners. the remaining reason isa reduction vol. eff. Of cause you could polish out but for the money I would expect a better finish.
The other item is the finish on the outside, it does have a nice effect. but it will become a dirt collector, and a b!tch to clean.

synolimit · 04-25-2016, 08:58 AM

I'll smooth it. Shouldn't cost as much as me porting the normal lowers.
