Jumbo's custom turbo build

Looking Goooooood.....!!

2 questions for ya:

1) Why the Rev-up Oil Pump.....??

2) Does the exhaust machining help that much......??

My block still has to be done so that is why i ask you this........as are mods are quite simalar already i thought i would like to keep this up :laugh:
 
Rev-up oil pump because it moves more volume of oil. Since I'll be heating my oil at a more aggressive rate, I wanted to have the capacity to move it through the system at a more aggressive rate as well. This stronger pump will help push it all through the new oil cooler. The OEM rev-up pump was meant for higher load than the OEM pump, just like the pathfinder cooling modification and the HR headgaskets (which require a little machine work to mate to the DE).

Exhaust machining - The common motor improvement packages START with the short block - If you want to spend more money and improve further, THEN you do the heads. Shortblock package is around $2300 US, Longblock (shortblock + heads) package is around $4500 US.

Again, since we are limited by our 5AT, I think doing just the short block would be good enough. The reason I did my longblock is because my engine had 110,000 miles on it and my valve seals were not great. With the additional pressures, they would have terrible blow-by. It made sense for me to refresh the whole engine.

Does it help that much? This package is rated to 650whp. Without doing both the longblock and the shortblock, I don't think the same claim could be made. This is not a one-off, this is from a shop that routinely does VQ engine builds so I'm pretty confident I can go with their recommendations.

Ok clear on the oil pump :tup:
You mean by doing the exhaust....the exhaust porting in the block or the exhaust system...?? I was talking about the exhaut porting on your block.

By the way how many CC's injectors are you going to run....??

And what compression of pistons will you be using...??

I am talking about exhaust port matching the block to the exhaust manifold.

OEM GTR injectors at 550 cc

8.8:1 compression

Isn't that porting done on the heads? I thought the difference between a short and long block was the inclusion of the heads...?

Yes, that's correct - the difference between the long block and the short block are the heads. When I purchased a longblock package, the shortblock package is included.

Let me clarify on the exhaust - I was thinking, "port matched" to the exhaust manifold - which in fact, has NOT been done. Don't want to post a false claim, lol. So there has been no machine work done to the exhaust in the second photo below.

Heads:

It would be nice if I could show you the exact same shots in a stock block so the differences would be obvious. I'll look around but anybody else feel free to post...

build update

The original engine has been removed from the transmission and the timing cover, valve covers, upper/lower oil pan have all been disassembled for cleaning before media blast and ceramic coating. These items will be going on to the longblock package once they have returned and look all new. Just cleaning the upper oil pan - not coating that.

Sorry for the picture quality - not sure why they are a little blurry.

The valve covers will be cleaned and inspected, along with the timing chain. I'm getting a new PCV valve. In general we're removing the factory brackets and using removable restraints.

IMG_6274.jpg

Getting the timing cover coated is going to extend the build by a day or two but I'm thinking for the effort I'm going through for everything else, why not? I'll be sure to keep the bay clean, lol...

Next visit to the shop - June 1st.
 
All of the coatings I'm using on the pipes, coolant lines, timing cover, etc. are ceramic - so they will be flat looking. The theme of the engine bay has been black/sliver or black/chrome, so I'm sticking with it. The valve covers are already flat black, so most likely I'm just cleaning them up. Every little request like this is a charge - making the cost continue to creep. Plus, waiting for the parts to come back from coating extends the build by a couple days and I'm already DYING to get this car back.
 
Rev up oil pump does not move more oil, the rev up engines rev higher than the non rev ups. There may be a material change but it does not move anymore oil. Neither does the Nismo oil pump, just a material change to rev to higher limits.

Ok but in both cases......rev-up and nismo.......are the worthwhile doing with a F/I set-up....?? Or is it overkill till a certain point....??
 
Rev up to non rev up oil pump pricing should be just about the same. The Nismo oil pump is 8-1k so that is a bit overkill. Rev up is probably worthwhile, have only heard of very few oil pumps breaking.
 
I saw the engine! Good bit of progress made on the fuel system. The fuel pump been installed in my tank

The OEM runners mated up to the CJM fuel rails and 560cc (OEM GT-R) injectors:

IMG_0837.jpg

IMG_0838.jpg

The upper oil pan has been mounted to the block and an oil return fitting has been welded into the pan. OEM sensors have been removed from my core and installed on the built motor.

IMG_0839.jpg

All the radiator hard pipes have been removed, trimmed & shaved with an odd fitting welded in. The pathfinder cooling manifold has now been removed and all these parts will be ceramic coated black.

The silver ceramic coated timing cover is due back in the shop Wednesday, which means the motor can be finished and mated up to the transmission by the end of the week.

When removing and breaking down my old motor, we discovered that two of the spark plug seals had failed and there was oil in the spark plug well. This means getting new spark plug seals and guess what? You can't buy them without buying the whole valve cover brand new.

IMG_6274.jpg

I've put out feelers and found a few people willing to send me what they have but the more I consider it, the more I'm thinking new seals would probably be the way to go with a freshly built FI motor. Think I might just have to bite the bullet and buy a new set of valve covers & seals.

Almost there jumbo.......:tup:

Rookie so you mean oem VQ35DE pumps that could brake........not rev-up's. So therefore they use rev-up's now.
I just want to changed all these thing to the engine making it brand new. So then better get the rev up i gues.
 
The pumps I've read about breaking are both rev up and non rev up. Mostly drag racers breaking the key way. Either pump new will be fine, the rev up just has the slight advantage that it is meant for engines reving into the 7k range vs 6k.

From the IPP site:

http://www.importpartspro.com/ni35oemoilpu.html
Product Description

The Nissan 350z OEM Oil Pump for the 2005-2006 manual transmission Z with the Rev Up motor. This Oil pump has better flow then the regular pump from the earlier model Z so it is recommended for use in rebuilds even on the earlier model Nissan 350's.

----------

So that's not really true? Better flow to me means more volume in a set amount of time. Not that it matters to my build - as you said they will both do the job, even at the OEM flow levels. Flow specifications are not listed so I have no numbers to back up the site's claim.
