Nice update. I am looking for a new exhaust as my hks knockoff has horrible drone. Does this exhaust have drone? PM me a price if so. Also yes kids are definitely a blessing. I hope and pray I have some before I turn 40....currently 34 and divorced twice with a broken engagement. I have the worst luck. lol. Any the progress is looking good.

I have the same Invidia exhaust and I'm very happy with it. I also ran the HKS knockoff first (huge mistake) and I agree it droned terribly. The Invidia is amazing for the price, no rasp, and I can cruise on the freeway at 65+, barely any noise. That's with Kinetix HFC. I've driven a few places with the wife and she never complained, so that's usually the stamp of approval.

The new motor should be dropped off today and I can’t wait. I’m giving the flywheel to the machinist at work to drill the VR6 bolt pattern into it. We’ll we filling the VQ35 holed with rod.
FYI, if you want to replace your Pilot bushing with a bearing; buy part number SCE 108. $3 at Autozone. It’s the same one other places sell for $15.

Time for a little update! I got the new motor torn down and am happy with what I see. I spend time to clean up the block and give it a nice gloss black paint job. The head was o-ringed to match the copper gasket that came with the motor; I ordered a new copper gasket to bump the compression closer to 9:1 from the 8.5:1 it was at. I also ordered some 276 camshaft to compliment the head.
I have the flywheel at the machine shop and should get it back mid next week with the VR6 crank bolt pattern cut into it. I should have the new engine going in permanently within a few weeks and then I’ll start making real progress.
Regarding the CAN bus interface, the engineers are starting to design and build a unit that will run all the gauges using GM based sensors. It will also have inputs for a tacho pulse and VSS pulse input. They are going to start with the 350z and then expand to other makes as the hardware stays the same; they just have to reprogram the unit for another car’s CAN protocol. We’ll be lucky if we can use the SAE OBDII protocol and not a vehicle specific one.
Yes I’ll posy Pics later…..

You might need a slightly different protocol. At least with alot of those 'universal' readers and guages, there's a nissan specific mode or something like that (for anything more than just pulling codes) that you have to use to prevent the can bus from shitting itself.

yes, reason we chose to use GM sensors is most all EMS use them. I'm sure the SW engineer will figure the CAN protocol out. These guys at work write code to talk to a M1 tank and M2 Bradley 1553 COM bus. They are damn good!!

Here is a pic of one of the adapters completed and bolted to the new engine. I also got my new tag!! The last bit of parts should show up this week so I can get the block bolted in the car.

I can see that, but for the car guy they will notice "350" on a 350z and that is does not sound like a 350z under the hood. I can live with it.

I may just end up making kits for people to bolt this into a 350z or G35. Up to this point i was thinking only hardcore DIY people would be interested in this. I'm also hearing that a lot of people are just blowing up the VQ35s even when built. the VQ35 also cost WAY more to to build and make power.
Here are some pics of the ROSS 82mm pistons and Cunningham I-Beam rods.

I'd be interested if I popped my motor.
Where are you hearing about people just popping built vq's?
I guess it all depends on who builds the motor, but I don't hear horror stories anymore. Usually when something goes, there's a good reason for it.

Every turbo 350z owner I have met has had a blown motor and some people in Tampa who work and worked at some well-known 350z performance shops have told me this. They said over 600hp they eventually all blow. I will quantify my statement by saying this is just what people tell me. What I have seen, been told and read on this forum and other is where I am forming my opinion.
Here are some shots of the oil pan modified to fit over the steering rack and I Tig welded an AN-10 oil return fitting on.

Anyway back to the vr6 engine. Oil pan mod looks simple. How high can these things be made to rev with solid lifters, dry sump etc?

There are a lot of members on this board making 600whp or more and none of them seem to have an issues. In fact, a few of them installed, built, and tuned it themselves. Not sure where the forum "blowing up" comes from but, ok. The people working with good shops seem to have good cars. No engine at 600hp is going to last forever, but that's just part of the game.

Well as much as we like to think this and other forums have a handle on the Z/G community. You'll be surprised how many folks don't use or know of the Internet! Even more so don't join local clubs or frequent the night scene...
