Any updates??

Just a quick update, the car has been running just fine until the crack on the drivers side has gotten much worse causing bank2 to run ultra rich. About to send a second sample off to blackstone. Sold my wife's beemer and bought her a g37 coupe and she loves it...
I still can't believe all of the turbo kits now popping up here on the forum..

Is there any way you've just got an O2 sensor going out?

That's what I was thinking at first but after switching them up and doing some logs the problems was still there. It wasn't until I shined a flashlight under the heat shield to see all of the black exhaust coming from the manifold.. Going to take it off and have it welded up and see how long that is going to last....

My local shop said they would be able to weld it no problem. I'm sure someone local can do the same. Were yours coated? Can you get it out without pulling the motor again?

Considering starting a thread to see who has logged the most miles and what kit while boosted.. Before I'm forced to spend more money on another turbo kit I want to really do my homework..

Great news chuck, thanks!! They were not coated but heat wrapped..

I thought I saw your kit was for sale?

From what he said they just have to grind it down, heat it up (600ish degrees) and then weld it. Then let it cool really slow. I didn't think you could weld cast iron, but he's in the NHRA hall of fame for building cars so I'll take his word for it.

I was going to sell it but don't have another 9k laying around. Don't me wrong people I like the kit...

Used to weld cast iron all the time. All alloys. The way you weld it, depends on the alloy. In a nutshell. You V out the crack with a burr bit. Heat the manifold up to temp (depends on alloy on how high). Some alloys, you have to use the backstep welding method. Some alloys you have to peen the weld after welding. You also have to watch your interpass temp. You don't want it to go to high. So now you can wrap the part in Kaowool insulating blank, or oven to slow cool. ;)

Forgot to add. Before you start. Bolt the manifold down to a piece of thick plate. Like 1" thick. This keeps the manifold from distorting.

Wow dude. I sincerely hope that you can finally put the problems to rest with your build. Should be good to go after the exhaust manifold(s) get squared up right?

I know it's kinda off subject but I was just looking at the q60 concept and it will have a 3liter twin turbo engine.. At this point I'm almost certain the new z will be fitted with that engine..

Quick update, at this point I was able to order a new gtm drivers side exhaust manifold. I used a vender just to make sure my money would be refunded in this case but turns out gtm is using a redesign for their casting to hold more heat. The gtm kit is a very good kit other than the exhaust manifolds cracking but then again the greddy manifolds have cracked as well. Hoping I can get by with this until Charles has come out with his new kit and may go for more power.. My new motor is smooth as butter now with zero issues idling or running.

Have you gotten to 17psi?

Yes after tweaking the boost controller it hits 17psi easily but have only ran it up that high a few times.. Will be sending another oil sample to blackstone soon and will compare the first one to the second..

COSMO how many times have you change the oil breaking in the build motor or in how many miles?

I did one at 600 miles while using the Nissan 5-30 ester oil, another done at 1500 miles with motul 5-40 and about to do another at 3000 miles again using motul 5-40.... :tup:

Thanks for the good info COSMO. I'll do something similar thanks man :tiphat:

Just brain storming here but since some of these single turbo kits claim to spool just as fast as a twin turbo then why didn't Nissan just design a big single turbo for the gtr..?? ? Also it appears the new z will also be a twin turbo.. I'm sure Nissan knows what they are doing by making v motors a twin turbo setup..

Can't help but notice you really have something against boosted performance don't you. Since obviously your not talking about the vsr single turbo kit when your always defending that shop.

Not at all, actually I was going to buy a kit from bp but didn't want to spend thousands of more dollars not knowing where he may be in the near future.. As far as the vsr single turbo goes, yes that could be improved in many ways just like bp has revised their kit already a few times only to make it better.. Also I have yet to hear anyone blowing a motor with the bp kit which is amazing but that just shows how well it was designed..:tup:

Isn't the whole point of a twin turbo set up to avoid turbo lag?

Yes, actually mike from gtm wrote a great article of the comparison between a single vs a twin.. Don't get me wrong a single turbo isn't bad at all considering it is a bit less money and Alot easier to install.

I did my first as soon as the oil temp read 180. I have a greddy magnetic plug and there were enough particulates to make it worth it. Im doing my second after 50 miles then again at 1000. Using regular oil in 10w 30.

Why the 10w instead of the 5w? For break in you actually want the clearance as close a possible so in can break in correctly. I also have a magnetic oil drain plug to help monitor particles.:tup:
Have you started a thread on your motor build and specifications?

Changing the subject but I saw a new Z06 at the casino's this past weekend and it was pretty nice. I have never seen rotors front or back so big. Can't imagine what those things weigh after getting a good look at them..

The builder of my engine told me to use 10W. He has built many engines so i figured he would know better than I would so i didn't question it. I could ask him why recommended that weight.

No build thread, but I will start a new one once I get this thing back on the dyno.

Wont get into a debate but the 370z and the gtr are both broken in on 5-30 with the same oem bearings.. What comp did you go with and overbore?

I am just .01 over since it was dropped into an engine with 100 miles on it.

11:1 compression because I only run E85 and wanted the low end a bit snappier. Plus it helps spool response.

GTM Arias extreme duty pistons.

Didn't know Arias was making 11.1 pistons now. I know me and Charles had first custom CP pistons made 11.1, Right on...

GTM customs up the Arias.

GTM? bahahahahaha... Good luck with that..

What the hell do you mean good luck? They are already in my running motor.

TopGunz dont worry about him. The pistons you have came straight from Arias and are built to a custom spec. I have them in my Z and they work Great!

aww well that was sweet but I was reffering to people getting anything from gtm..

Yeah Im not worried. Ive done my homework.

Cosmo we know your hatred for GTM. Getting items from GTM has slowed to a snails pace and I should know!

I know where they stand with things and they are slowly working to get themselves into a position to make things right from what I am told. It is going to take them atleast a year if not longer. Take it for what you will.

Back on topic...

Nothing would please me more for them to make things right for everyone including myself. I always considered gtm #1 on my list before they got over their's heads, that's why I chose their kit in the first place.. :tup:
I applaud sam if he can in fact dig himself out the hole he dug and make things right..

Custom CP 10.1 Pistons before assembly..:tup:
