Impressive piece of CNC work, but I don't see any baffles/flaps/trap-doors in the sump and to my mind, that makes the sump design a bit of a woftam.

It is not clear to me how the oil gets from the external pressure pump into the oil gallery either - modified front cover ??

Not a bad idea in principle, but if you are going to spend this much money, go Dailey Engineering and do it right.

This is going to be a very affordable option. Going Dailey is going to be $$$.

As for the size of the pan I'm not sure I just was told it's bigger than their other pan so I would guesstimate you would be closer to 9-10quarts.... Just guessing here since their other pan is in the 7-8quart range.

This is an upgraded wet sump system. As soon as their are pictures of a full setup I will share them.

Could a stock block sustain higher rpm's? So far yes... There hasnt been a failed VVEL yet that I know of and anyone who has run 8k+ rpms has blown their motor due to the oil pump failure. I guess I will have to try it out on my Nismo... 9k NA muahahahaha

There's another thread (or several) for that :icon17:


Bullitt, congrats on continuing to innovate and push your build :tup:

Thank JARBlue! That was the point of that statement. I will say this... These will not go on sale unless they are on the shelf ready to go. I had a long conversation last night with GTM and they fully recognized the issues from the past. With that said I will only be getting it when it is on the shelf. And depending on the interest it may be something regularly stocked. I should know general pricing in a few days but from what I was told this is a much less expensive option that will be a nice safe guard for our motors.

Ohhh and there will be a conversion path to the new V3 manifolds for those who are interested. After last nights discussion I made it very clear that the people didn't want the same issue from the old design and that they would be better suited upgrading people to the new design and new material construction.

The stock engines crank, cant handle high rpms with the stock rods n cylinders, even though u upgraded to a better oil pump system. You still need to change internals either light weight rods n cylinders on stock crank, but you must keep ur temp below 220F and rpm cap of 85xxx, or fully build internals, buuuut if ur going that route its better to just boost. If ur chasing #'s.

In my opinion its just a competition build, just for classification. In reality its tooo much $ for high rpm build. Or maybe u got that N/A build bug going.

Thank you for sharing bullitt5897!

I am curious about the manifold development, and previous GTR 370z manifold is there any more information and will number of gains be provided?

Thanks :tiphat:

YOU MADE MY DAY !!!

I've always wanted this mod for my stroked HR, Car easly capable for higher rpms but been always asking tuners to set the limiter @ 8k only due to the stock oil pump.
Yes there's Nismo Oil Pump for our HR/VHR but never trusted it ..

umm.. how much roughly you think it's going to be ?!

I'll believe it when I see it...

yea, why are they investing time in this when OneslowZ showed of the GTM manifold in his Z. I bet more people will buy that before this.

Dwnshift mentioned that they was changing the stock cranks after every race last year. This year, they're allowed a strong crank. Last year he said the cranks had cracks in them after most races. BUT remember this is on a full flat out racecar, not a DD/track car. For someone like me. This would take the worry out of doing trackdays. :D

So from the little bit of information I've gotten off this is that just like with any build on a stock block it all depends how you hard you drive the car. Cooling seems like theJpr issue.

Main*

Cooling and the fact that the pumps fail at higher rpms... If the pump fails the engine fails... This is a great safeguard!

Wonder how a stock VQ will perform 12psi tune at 10k RPMs..

If you could get maximum performance safely why not?

You would need turbos designed to flow efficiently at that high an rpm, which I think would be difficult. For example, in an interview with an engineer for the ferrari 488 gtb said they limited the rpm to 8k because the turbos couldnt keep up and it would be spinning the motor more without making anymore power.

But dont get me wrong, if I could have a 9k TT Z I would rev to redline even if it doesnt make more power :tup:
