I would probably prefer if the majority of them were taken care of during January. But we can probably go a little longer where needed.

Hoping to have the Stage 2 kit done next week!!! I am already a little late on it but its being wrapped up. My poor Z hasnt had more than a hour of down time since putting the turbos in a couple years back... now its all taken apart waiting for finished fuel pipe/hose.

So whats the benefits of these FPD Rails over traditional one ? which one GTM use?

Our FPD rails are higher "flow", use AN fitting attachment, allow various plumbing configurations, look better, and are the only aftermarket rails available that retain the fuel pulsation dampers... a very important feature for VQ's which generate part throttle hesitations at specific RPMs without FPDs.

PM the price these fuel rails with the necessary hardware for installation shipped to UAE.

Very interested. don't keep me on hold for long.:p

Sure! You need just the rails, right? You already have AN hoses or the ability to make new ones?

Spohn just asked me to machine a billet diff cover. I could machine that rather quickly but I am curious if anyone else has interest in that. We could add a little bit of cooling fins, structural rigidity, and added capacity (perhaps .5 quart). Does something like this interest anyone else?

Yep for sure.

Bonus if you can put a hole for an oil temp sensor as well

I could put any ports for fittings or sensors anywhere you guys want!

Drain
Fill/Level
Temp Port
Separate Fill from Drain? Probably ideal for those who run coolers.

Do you guys jack up your car from the diff? I know I do. But when I had the Nismo cover, I would just put the jack in front of the fins and lift from the iron only.

And two more holes for diff cooler hoses so we don't have to use the drain/fill holes and make a mess lol.

I used to, but don't have the clearance any more lol.

But yes seperate fill/drain and an extra port for temp would be ideal.

Excellent. We are going to pull the cover off the 350 tomorrow. I will leave the cover on the 370 to reference clearance/space to go larger and add ports.

I would say the fins get in the way more than anything and most people getting this would be getting a diff cooler anyways.

I can't go crazy on the fins because it's a billet part. A cutter has to be able to fit inbetween and ideally still have air on one side to get a nice finish. Real small cutters would add tons of machine time and/or lower finish quality. So the quantity of fins would be lower than a cast part. I will post up drawings and see what you guys think before I cut.

That is true come to think of it. No fins would have more capacity in the design.

Yeah I'd just shoot for capacity and 4x ports set up for drain, fill/level, and cooler lines. People running coolers will probably have the temp sensor in the cooling lines/system anyways.

God Dammit Charles, stop offering products that I may want to buy, between you and Fast Intentions, I will never commit to buying a pool or something stupid, damn you, damn you all.

Thanks for your work buddy. Nothing beats built to order, high quality products.

Yes Just the fuel rails with fitting that accept -6AN hose please.

With the new CNC here that dedicated for just auto parts... its never going to stop now! I think I am finally done purchasing most of the new tooling for it (aside from little per-project needs). I have several hundreds of pounds of aluminum showing up here Friday. That is only the start! I am making my list and checking it twice and I will be ordering damn near a truck load of material here! Let the billet goodness flow.

You guys are going to love (or hate) when I start getting deeper into my engine build and bay cleanup

Because of this I want to delay mine... Would hate to finish it when you are releasing all these parts and then have to tear down again (ie: oil pump setup).

phunk, you are going to cause some divorces if you keep this up. My new wife already suspects something is funny. :icon14:

Justin pulled the diff from the 350 today and we have the cover soaking in degreaser. Tomorrow I will mount it in the CNC to get precise dimensions on the bolt locations and etc. I will start a new thread next time I post about that project. This week probably.

Today I made the hard pipe prototypes for the stage 2 fuel system and figured out most the hose routing. Tomorrow and Wednesday I will finalize it and that will be that.

Tomorrow I will start packing up the paid-for RRPs since those should really be shipped ASAP.

Got it. PM sent!

PM replied

thats fair, thanks for the info dude!

i would be interested in this

^ nice to so real parts made and real drivers wanting them.

i feel the same, and same goes to you ;)

im really excited about the RRP, not only so i dont have to even think about fuel starve, but also being able to lose 75-100lbs in fluid weight on track, thats going to be worth a significant about of time on track, and will feel SOO much better. also for street driving, i hate when im on the lower end of a tank, and have to baby a right turn interchange, not that im trying to go track speeds on the street, but its like we all modifiy our cars for grip, and even under the limits of adhesion on the street, our cars can fuel starve on a right

+1. My closest track has a very long, very off camber sweeper and even heading out with a full tank, I cannot run a single full session without having issues. That's even pussy footing around on street tires (my hard core track days are behind me and it's just fun 6 or 7/10's now). I don't even want to know how quickly fuel issues would show up on this track pushing hard on race rubber.

another thing, i was having some minor starve issues even after topping off my last event at buttonwillow in a couple turns since i switched from Street tires to r comps O_O

slowdown bro LOLLL, I will have payment in no later than next week.

Phunk I too would buy a finned diff cover from you today if you had one.

He might be thinking of doing a diff cover with just more capacity which will have the same effect in cooling as the fins. This way we can still jack the car up from the diff. We'll see. He knows what he's doing. Even with the fins it will have more capacity. But without you might get more.

Putting in some OT to take care of my debt :)

the nismo finned diff cover from z1 fits a vlsd pumpkin. ( I upgraded to nismo finned when I put in my Quaife)

I'm sure Phunk's would be better, but there is a good (100 buck or so if I remember) option.

Direct bolt on no mods needed.

Nismo Differential Cover

yeah if you just want the added fins, sure just get the nismo cover, but phunk is talking having added ports for diff cooler setup and higher capacity

ya i had one of those on my 350. i cant remember if its on the US spec nismo cars or jap ones or what. Its meant to go with the entire filled differential casing... but people add them to normal diff casing and get the very tail end of the fins. there is a normal nissan part number for that.

i have one on my 370, its a nice unit, and the fins are better then nothing, but im still going to setup a diff cooler

tonight we put the diff cover in the CNC to get exact locations for the bolt holes, etc.

After programming the locations into CAD, we played around. We have 2 drains, and 2 fills at the stock height. While there is added displacement, until we measure the stock cover (from fill plug down), i cannot compare.

This is totally open for suggestion. This was just the preliminary results of messing around, and I am sure the part will change a lot before we machine it.

So, looking for feedback on this!

Got some mild cooling fin work there... theres not much airflow in this location but even those fins more than doubles the radiant surface area in the location.

Some of the radius are unrealistic to machine in, and the thing might look a little more boxy before its said and done.

Anyways... some of the first steps have been taken!

I know I said I would post a new thread yet... but I guess I am not ready to take on a ton of attention for this right now. I would rather have a more solid footing.
