I don't want to side track this, but another vendor has built a external oil pump (Dry Sump) system.
No I have not seen it function, but it looks nice.
The only issue is. it may take you a year to get it, and then after you get it will go on sale for 20% off.

I cannot wait to see more photos of the intake manifold Charles. The ones I have seen so far are Bas@ss

This one is totally different

Are you talking about the Dailey Engeering setup? Their products are very nice but I am not personally a fan of dry sump for street car use. It's a little messy and over complicated for me. The Dailey setup is so expensive that if I went dry, I would probably just machine a similar setup myself to save cost.

What I am building is a factory type setup that is based on a superior and proven oil pump that has output volume that is matched very well for the VQ

I'll email you later..

The oil pump on the VHR is less of a limiting factor than the VVEL heads. Has anyone attempted HR heads swap?

There is a member here that has done it, and there are some race teams that have done it.

The HR and VHR blocks are essentially the same from my research. The HR heads will bolt right up. But you do have to sort out timing covers and wiring and electronics, and there are more than one way to do each of those.

Yeah I took a peek at a couple race-prepped 370Z's (SFR Enterprises team had a couple down in Houston for the World-Challenge class stuff during the Indycar weekend here) - and they were running VQ37's w/ HR heads. They seemed to be using our timing covers and whatnot, because you could see how it was meant to fit VVEL, but the harness connectors and whatnot for VVEL weren't hooked up at all, was just an empty housing there or whatever. They were also running the engine management with an aftermarket race ECU from Motec.

that member is me which you asked a few questions in PM on the subject few months ago...


but seriously this HR head setup is not for someone who isnt using the car for the track.

I have some ideas that might make the conversion a lot more simple. I think I can do it with the VHR timing covers and VHR ECU, making it essentially just a headswap with no added complication. I should know by summer hopefully.

But isn't the whole point of the head swap is to run aggressive cams and a standalone ECU since UpRev has limitations?

For me, the point is to eliminate the mechanics of the VVEL system. The camshafts and the ECU are up to each user to choose based on their needs from there.

considering the factory vvel is set at .460 or so max lift they better be some BIG hr cams, only advantage would be reliability at higher rpm. You would lose a lot of the drive ability of the car for this so again not for a street car. Also you can run HR cams in VHR heads with minimal work so why even swap the heads?

VVEL from JWT research the stock maximum position is around 280 degrees of duration and 0.450 lift, about what an aggressive street cam would be.

Again I do not recommend anyone doing this HR head swap for a street car .. but only for a true track car that needs 375whp+



where did you see about the capability of running the HR cams in the VHR heads ? link ?
edit: how will you install those cam sensor on each of these , 4 in total... the vhr valve cover aren't the same....
also if you don't swap the HR head and the timing cover .. you wont have VTC on the exhaust ... kind of not optimized

Why do you guys say this is not for a street car? 375whp is great for all-motor and all, but I am perfectly cool with 700-800rwhp street cars!

The advantage of reliability at higher RPM is precisely the goal. If not for that goal, there would be absolutely no sense in removing the VVEL heads. The drive-ability of a HR without VVEL isn't so poor that you should say its no good for a street car, lol! Its still much better than most import cars. VQ's have rather decent torque due to the VVT system. The lift is the only thing that would be gone.

HR cams should not be put in a VHR motor. Obviously the intake cams could never go in since the VHR does not have anywhere to place them. The VHR exhaust cams are offset from the valve centerlines and require a special profile because of it. (According to Jim Wolf, I have not measured it myself). Therefore HR cams shouldn't be installed to a VHR even if they did fit.

I would not use the VTC on exhaust for HR head swap. The exhaust VTC is the main complexity of the HR swap, and to not bring it with would make life much cleaner and easier.

Exhaust VTC is all about emissions, and does little to no good for power and torque.

Here is the phunk's style of HR head swap. VHR timing covers. VHR exhaust cam gears. VHR intake "cam" gears with trigger. VHR timing covers. HR cam sensor positions in the valvecovers plugged. Stock 370z harness and ECU. This is my plan and how I will be attempting it. No guarantees it all fits or works, or what the VHR computer will do when the VVEL solenoids are gone. But I will let you all know! I am pretty confident that this is going to be the winning formula for me based on what I have compared and looked at. Of course, I can just machine custom parts if needed somewhere. EDIT: forgot to mention. Let me also say that another big perk of ditching the exhaust VTC is that I should still be able to run VHR style pistons. That is a big one right there. I have to confirm valve placement but I say its most likely to work.

something that I want to specify, the HR head swap that im talking about is to have those big *** cam for the max power...

So this is why I wouldn't recommend this for a street car ..
not because you can drive a 800whp car which is F/I and not N/A, your idle with those big cams and overlap you will need about 1500rpm idle at minimum ,,, good luck in your stop and go traffic. your clutch will take a beating on this alone.... thats my opinion anyway who care , right ?

next, according to the research of a friend and a certain company , you will want the VTC on the exhaust . just saying... will see how much power you make at the end ;) and more importantly how your power curve will be.

Ah yes I will not need the large camshafts. I will probably even run the stock HR camshafts. They should be more than fine for 700+ when boosted.

Trust me, I do not want the VTC on exhaust. It will cost me TONS of time and money and it will not help my powerband much at all. Exhaust VTC is all about emissions.

Keep in mind that VQ DE's and VR38DETT from GTR do not use exhaust cam phasing.

The potential perks of stock ECU and VHR style pistons is well worth it.

ok now I understand what you actually plan ;)

we weren't exactly talking about the same goal....

anyway im not debating on the use of vtc with your setup , which isnt a problem,,, but i would strongly suggest those who would ever wish to go with the HR head for those big cams ,,, the exhaust VTC should be used.

BACK TO PROPER TOPIC FOR THOSE LOOKING FOR UPDATES: (I will start new threads this winter about the intake manifold, oil pump, and HR conversion products that are being developed along side my engine build).

Spoke with my anodizer this morning. All the parts are hanging on the racks ready for dipping!

The only hold up is he is waiting for more blue dye to make my dark blue. While the RRPs this batch are going to be black, I have several other parts there for blue. He says the dye will be there today or tomorrow!! I am hoping to pick up the parts tomorrow, otherwise I will swing out there Monday!

black? I wanted hot pink.. no deal Charles!

careful what you wish for.....

if u do pink, I want a clear cover, bling!

oh God.. haha

Knowing phunk, he will do it just for sh!ts and giggles. LMAO :D

I have the parts back! The page has been updated to accept the remaining transactions for deposit paid members.

370z Road Race Fuel Pump

I am not sure if I will ship any this week or not. I will at least start packing them as payments come in. I might spend the next couple days seeing if I can improve the hose situation for easier installation. So there is no huge rush on the transactions. Whatever works for you is fine. However, if you need to extend beyond the next few weeks, please just let me know.

Wow. 19. Sweet. Love when you see things pay off.

The rest of my payment has been sent! Take your time if you need to make things easier. I won't be mad at you for making things easier for me install wise lol.

I'll PM after I check with Wifey on January bills.

Phunk, have you thought of a way to use the RRFP with the aid of another small device to eliminate the OEM pump? It seems where stuck to having two systems inside the saddle bag tank we have. I know there's nothing wrong with what you have done and it's probably a waste of time any money to do anything else.

I'll just worry about what's to come

Yes. We can use it to replace the oem fuel sending unit with our stage 2 fuel system by adding a filter inline. This is because we have a regulator in the engine bay at that point, rather than having to integrate filter and regulator into the RRP.

It will involve a little reworking to the road race pump, and it will come at a little sacrifice of its starvation elimination qualities.

I'll keep this setup then. lol

Paid Full payment last night. Check you're Paypal.

Chad

I'm interested on the full system you were developing since my power goals are similar to yours. Should I pay now for the pump or wait until you have an entire package available?

Payment Sent.

Apologies! I applied your payment to the correct invoice last night but I marked it on the incorrect screen name here. FIXED!!!

Good question.

If you wait to install the RRP until you have the Stage 2 kit, there will be some parts that you do not need from the existing RRP installation kit. There will also be a part or two that gets replaced in the RRP itself.

You can choose to wait until the full order is ready, and pay at that time. Or I could setup a custom charge for you that would be less the installation specific parts, and ship the RRP to you now. Regarding any parts that would be later changed over for the other installation style, I think I will probably offer these conversion components free of charge to anyone who wishes to make the conversion or wants to go back and forth and try it different ways, etc.

Although there will be a different "installation kit" (for a little cost) for the RRP in that style. But it shouldnt cost much at all.

Ok, thanks. I don't really need it now and I rather have all parts at the same time. Can you give us a quick rundown on what will be included on the stage 2 kit?

It will be the entire fuel system between the sending unit, engine bay, and back again! Our new version of VHR rails that we call our FPD rails (fuel pulsation dampened), external regulator, stainless hard pipe, and teflon with SS braid hoses.

The stage 2 kit with just the stock sending unit will be good for 600-750rwhp depending on fuel pump used and type of fuel/dyno. With our twin pump assembly, or with the RRP with added pump, the sky is the limit!

If you havent peeked at our FB, heres a couple pics of the FPD rails.

so Phunk, what is our window to get you the full payment? just wanna line it up with my next pay checks coming in
