Wonderful 3 1/2 years and 22,000 miles and then ....
 

Short story bigger impact for me

The story:
Invitation of Nissan Switzerland
NISMO Nürburgring "track day" 23/09/2014

Ohhhhh Yeahhhhhhh :icon18::driving::icon18:

23.09.2014 / 04:00 in the morning
I started to the Nürburgring in Germany.
Open highway, no speed limit, no traffic.
Sometimes with speed over 175 mph (280 Km/h)
Was a pleasure :driving::driving:

11:00
Coffee break and refuel gasoline (after 280 miles)

12:00
Briefing and instruction of the Nissan Crew

13:00
Grid on the Nürburgring Nordschleife

13:05
"Gentleman, pleas start your engines" :excited:

13:07
Someone knocks on my window
"Hello Sir, your "Z" smokes a little blue from the exhaust" :eek:

The Nissan mechanic on site have recommended to me not to start.
The "Z" still run......and I can not drive a single round :shakes head:

Since that day, the "Z" is with my tuner.
For those who do not know my conversion, here is my build:
http://www.the370z.com/forced-induct...z-swiss-4.html

In the next few weeks / months we will analyze what happened.
If we have to remove the engine, I will at the same time upgrade the internal parts.
With us, the winter is coming and we have enough time to build up the "Z" perfect.

My wish list for Spring 2015:
The existing STILLEN-Kit
(Because we have officially entered this kit with great effort in Switzerland (carb legal))
AND I LOVE IT!

10 - 11 PSI Boost
460-480 WHP

Planned upgrades and service:
- 340lph fuel pump
- 750cc Fuel Injectors
- GT-R Spark Plugs
- Replacement of all belts (motor and supercharger)
- Replacement of all lubricants

Now the real questions:

1. Individual parts replaced?

- Piston
- Connecting Rods
- ARP main studs
- ARP L19 head studs
- etc.

2. Or even the extreme? :icon18:

- Brian Crower Stroker Kit (4:07 or 4:37)
BrianCrower.com | RunBC.com // Nissan // VQ35DE

3. Which compression would you with my power / boost (10 - 11 PSI) recommend?

- 11 Stock
- 10.5
- or ... ??

Many Thanks for your help and recommendations

@Vendors or Sponsors
Feel free to shoot me an offer by PM for the above items :tup:

With the stillen sc I would go 11.1 or you will lose a few boost of boost to make up for a lack of power..

So a little blue smoke but everything else seems fine? Have you checked the oil level in the stillen? Knowing how those things heat soat I can only imagine how hot it got at 280km/hr for an extended period of time.

Do you have an oil temp gauge? what was it reading during those high speed runs? I know mine will creep up with the turbo, I would imagine a SC would be worse.

Isn't the Stillen a selfcontained oil system?

:tup:

The Vortech V-3 SCi supercharger has an internally lubricated Transmission

The outside temperature that day was about 12 -18°C (50-65 F)
The engine oil temperature was never higher than 110°C (230 F)
during those high speed runs

The engine has been slightly unbalance after starting at the racetrack.
But this is only at idle Speed

Unfortunately I have no information about what is really going on yet?

Could be, I thought the level could be checked tho?

It just seems weird that a supercharger would cause an engine failure so early. What were your AFRs like during your high speed runs? What boost was the it pushing at those speeds? Just curious.

I guess its possible that the engine was not made to spec.

I look forward to seeing pics of the rebuild process! :tup:

Absolutely. My only point was that unlike an oil cooled turbo system, the Stillen SC has an independent oil source.

I must admit that I am the "Z" very driven at the limit.
On the highway, many chief vehicles (Audi, Mercedes, BMW and Porsche) have afflicted me from behind.
And it was very nice to see how quickly they disappeared in the rearview mirror. :tup:

I myself have the "Z" moved with the STILLEN SC in the last 3 1/2 years just for fun.
Swiss Alps, rides with GT-R's, racetracks and always at the limit.
I have very well kept it. All 4,000 miles was made ​​a complete service.

It was aware that at some point something could happen.

:iagree: We all play with fire

Dang that sucks. Usually blue smoke indicates fried piston rings, but there has been several occassions where it was come from valve seals. I never had either luckily (I don't mean that in a bad way)

Sorry to hear the issues bud... try contacting Abbey Motorsport in England, or Monstaka in France, they might have the engine parts in stock and might save you on import taxes and shipping. Just mention Alex from Real Auto Dynamics and they should be able to take care of you ;) Good luck!

Thanks Alex :tup:

no worries mate.. I've worked with Mark (owner) @ Abbey on numerous z33/z34 builds, as well as Charles (owner) @ Monstaka as well! Both know their stuff with these cars and are in the same supply chain as my facility :) Keep us posted!

sorry to hear about the problems.

would be interesting to see the JUN high comp pistons with e85 :P

Sorry to hear man but I am sure you will make her better than before.

We'd love to chat with you more about this and see what your plans are and go over compatibility of parts, recommendations, and information we might have. Please shoot me an email: markd@stillen.com Thanks!

Hey Guys

Thanks a lot :tup::tup:

@Mark
Very nice of you to hear
In the next few weeks as I know more,
I will gladly contact you for further steps! :tup:

Ivo

Sad to hear ! IT is, But make me wonder a little about their kit now 2 car (3 if you count mine) That has gone bye, bye, with very little mileage on them. I know you cant wait for spring already!! ;)

Hey ANMVQ

Thanks man :tup::tup:

I had a lot of fun with the "Z" and 3 1/2 years since installed the Kit

Greetings
Ivo

BTW: I know four people who had an engine failure here in Europe.
With a few miles.
Without more power! (Stock) :mad:

Hi guys

Time for an update! :stirthepot:

I just got the analysis.
The 2 cylinder has no compression and a blow-by. :icon14:
(See photos)

It's time (after 3 1/2 years) for a general revision of the engine!

Either a gentle Revision (only Cylinder 2)
or an extreme :tup:

My desire tends to extremes.
As written in post 1, I would go to a stroker kit.
(see link)

BrianCrower.com | RunBC.com // Nissan // VQ35DE

Type: Brian Crower
VQ37HR 4.34L - Includes 4340 billet crank, 92mm stroke (fully balanced), H-beam Sportsman rods (5,974 c-to-c), and custom pistons (choice of bore / compression).

Piston: CP Pistons-Carrillo
Bore: 96.00mm
Compression: 11.0 to1 or 10.5 to 1

What do the experts here in the forum on my wish list?

Thanks for the support :tup::tup::tup::tup:
Ivo

Sorry to hear brother. My previous motor suffered the same from Cyl 2 also. Lot's had to do with tuner. I still have that motor set aside and I am very interested to rebuild or at least tear it down to see what else could be wrong.

GL to you man, It would be awesome to see this build go further.

I would suggest getting another tuner for your next engine.

Well that sux :/ Mine was cyl 3 but completely shattered the rod.

On the engine front this is what I've been looking at for a block, He s a vendor on here :)

VQ37 Engine Short Block Packages - Nissan 370z/Infiniti G37 - Import Parts Pro

WOW! Great price for those short blocks ^^^

I turned to a Nissan specialist!

QAS from Germany :tup::tup::tup::tup:

For a second there I thought Ikea made a compression tester. Sucks to hear hope whatever route you go you get it together in a timely manner, If you do the brian crower kit make sure the shop that does it has done one before, there are multiple instalation issues with that stroker kit that must be adressed during instal. To many times I have heard of shops putting one together and missing some small part of the install. Even heard it a couple times where they didn't clearance the crank-case and the motor couldn't turn over.

I would steer clear from the BC stroker cranks. From what I have been told they very from unit to unit as BC has several different facilities making them for them. To give you and example if you had 5 cars: each car would have a different variation of the same crank... This may put you in a bad spot and future failure. I would stay stock stroke.

I say this next part with great caution: ( I know Im going to get flammed)
GTM does have a several billet cranks on the shelf... I saw them last weekend. They are full billet and 100x's better Quality than the BC. They had the two at the shop and the BC looks like a stock cast...

Good luck with the build!

Thanks Guys

For enlightenment! :tup:
We will look at the next few weeks/months, what we build!
I've been thinking, which is not optimal, the BC kit !?
GTM Stroker -Kit.....??????

For more suggestions or ideas I'm open.

Thanks for the advice

Ivo

GTM is very risky these days. I wouldn't give them a dime.

Plus for the GTM comment since the filled chptr 11. I wouldn't send them anything till I was holding in my hand

I would consider finding someone trustworthy local to GTM and have them go buy and pick up in person, since Bullitt saw them in stock. Might be the best route. Their quality isn't the problem, just the availability. If you could have someone go in and pay cash and walk out with product in hand, you'd do alright. But we don't want to go too far down the GTM rabbit hole in your thread. Just do your due diligence before paying for anything.

There are several members close by that could assist you if need be.

@All Vendors or Sponsors :tup:
Feel free to shoot me an offer by PM for the following items :tup:

My Goal is: 600 HP (480 WHP), 600 NM (440 ft-lb tq)

1. Brian Crower Stroker-Kit Typ: BC0229, VQR37HR 4.34L with CP-Carillo Pistons, Bore 96mm (Compression: 11 : 1)

2. ARP 202-4701 Head Bolt / Stud Kit, Nissan 09+ 370Z VQ37VHR Z34

3. NGK Iridium Spark Plugs from Nissan GT-R

4. 370Z Clutch and Flywheel Combo (for about 450 ft-lb tq and no rattle :tup:(if possible).

THANKS A LOT :tiphat:

Ivo

I thought you were already making that much power. Why not just beef up the internals and spend about $500 on cog pulleys from Vortech to spin the S/C a little faster? Unless you want the stroker just for the sake of having it.

No Sir :tiphat:

My 370Z:
Always on DynaPack!
Stock Power: about 300HP
With STILLEN: 500HP / 500Nm (200HP more than Stock):tup:

http://www.the370z.com/attachment.ph...1&d=1413047809

I understand the power (HP / WHP) not really!
If someone here he writes has 600 WHP would be the case here in Switzerland 735HP?? Pagani Huayra like 730HP ...

http://uncrate.com/p/2011/01/pagani-huayra-xl.jpg

Why are these upgrades?

Because we disassemble the complete motor and drill out the cylinder. :stirthepot:

Either the piston, the connecting rod and the ARP-Kit to be replaced,
installed or a stroker kit.

My desire would be to install the BC- Stroker kit.
More displacement (more room for power) and all parts included in the kit.
Not the ARP-Stud Kit

I hope someone can help me a bit in this project !?

Dang. Your car is beast man! I hope everything works out for you.

BTW: a Nissan GT-R 2014 has 550HP at us :tup:

I'm just 50HP behind :driving:

Thanks Guys

I have already received some great offers for a conversion.
I hope there will be added a few?

Thank you very much :tup::tup::tup::tup:
(So ​​I may come back again next year to continue :driving:)
