Nice videos mano. Glad it is finally all sorted out...

K

Just went through the whole thread.
Glad you stuck with it. You wouldn't have been as happy if you had parted it.

Beautiful build... how's traction from a roll in each gear? I love how the revs ramp up so quickly in each gear. That's what I'm shooting for, but the target is under 500 whp (from 400 whp currently).

Thanks, Kirk! Although there's a new problem.
I definitely wouldn't have been as happy if I parted it out. Fo sho...
Thank you, sir! You have a beautiful build as well.

Traction in 1st...HA! 2nd gear traction...what traction? 3rd gear hooks 90% of the time. It was maybe 65 at night a few nights ago and 3rd gear had a problem staying planted. My foot will have some fun as temps get colder.

With the drag radials on from a roll, it still eats up 1st and 2nd. At the track though, with a big smokey burnout, it felt awesome to have traction in 1st and 2nd. That was the first time I really got to feel the HP and it put a huge smile on my face:tup:

I couldn't see clearly and probably missed the post, but are you using the EVC 6? If I was to run high boost, I would love to take advantage of the target PSI per gear. Of course, it'll need to be optimized for the tires being used. Since I run street tires, I'd probably set mine to 6 PSI in 1st and go up from there.

At < 6.5 PSI, I can get it to fishtail in 2nd around 4k RPM from a roll on a good day. After things heat up a bit, I hardly break traction afterwards. I've not tried launching the car yet haha.

BTW... I finally watched the video with the speakers on ;)

Interesting thread to say the least. Like what you did 98~. The problems with the builder and time lines really don't seem that out of the ordinary. I've had the same bull happen to me before, and that was on turbo KITS. They say one thing, promise a deadline, you call back way past deadline and they haven't even started, or know nothing about it. I def felt the whole "paying customer = great service on a phone" then "you already paid, and we don't care about the issues you're having despite our promises and guarantees." It happens. The car mod business lives on rep from people like you.

Reading over the whole thread, I was chuckling how some forum members were pointing out some problems with Lutz's design, and the same issue they bring up bites you in the ***. I didn't enjoy that the process sucked for you, but now that it's pretty much over, it can be laughed at; IMO. Hind sight is 20/20 after all. That's what happens when a welder designs a turbo kit, and not an engineer. This isn't the 70's anymore, these are 200mph computers, hence companies specializing in certain types of cars; due to the wide range of differences that can be seen between makers.

Anywho, great looking car, and I hope it just gets even better. :)

I'm using a Blitz SBC-ID III. The Blitz offers the same target PSI if you also purchase their speed controller.
Thank you. I was blinded by Lutz's reputation and my first hand knowledge of turbo kits they have fabricated in the past. It still pisses me off everytime I look back at all the money I wasted due to their "expert" knowledge. Someone posted saying they could make their own kit for around $6k and Shawn laughed. I now know it could be built for that or even a little less....$1000 for a turbo and $1000 for intercooler, WG, and BOV (roughly speaking). That leaves $4k for materials and labor. Had I taken my car to the guy I'm workog with now, I could have had a reliable single turbo kit for around $4k-$5k.

I smell a business opportunity. :stirthepot:

Nice

Good to know that it all got sorted out. Enjoy your beast............

Wow! Congrats on your times man. Definitely lots of power with your trap.

Trust me...I've thought about it, but the guy I work with is still a kid. He's 20 years old and still goes to college. The car thing is his hobby and he makes money off if it as well. I don't think he'd have time to be knocking out turbo kits.
Thank you...but there's a new problem now. Since I put race gas in at the track, my motor has developed a ticking noise from the top part of the motor. I went to see a friend at Infiniti and he tried resetting my VVEL Thursday and Friday...the noise is still there. So now we are going to do a compression test this week.

Th car still drives fine, AFRs are on point, gas mileage is around 15mpg, and I still did 1 more 1/4 mile run and have been boosting it since with no problems.
Thank you. I'd estimate my power to be around 450-470whp with the trap speed. It's definitely not making the 506whp when I was tuned at Z1, but I am just running a GReddy TT base map that Z1 sent me. I don't want to get the car retuned until it's 100%. I was ready to get it tuned until the noise in the motor started on October 1st.

Your power of around 450-475 is great! I'd like a little more to fully utilize the potential in 3rd and 4th. It's too easy in those gears with 400 whp on tap :excited:

BTW, can you post footage of the sound with a light revving? Have you checked the oil content to see if there are any shavings?

Could be inadequate oil/oil pressure, lifters or VVEL system is failing.

May be from the high boost (highest for the vhr ive seen) and the VVEL system is breaking down from it??

could a bad head gasket cause you to lose oil pressure in the heads?

I hope you find the problem

Itb08-028: Noise From Bank 2 Vvel Actuator - MyG37

Related? Similar noise ?

I'd like to trap 125, so that means I want 520-550whp. :driving:

I'll post a video later tonight when I get home from work around 11pm. I gave a few videos made of the noise. I changed the oil Friday night after 1800 miles. The oil had 0 shavings in it:ughdance:
Lifters maybe? But the tech at Infiniti was saying something about VVEL and how it couldn't be the lifters. This stuff is beyond me. I'm not an expert at internals. I'll do some data logging this week and check oil pressure.
This is what the Infiniti tech I went to was talking about. The link isn't opening on my phone, so I'll have to check it later. But from what the tech said, it's not the VVEL.

Hopefully its just a bad head gasket and you just need to replace with a thicker/Stronger gasket.

The tech may be thinking vvel since its what our car uses to operate the intake valves which is what I was sort of thinking.

my question is, if it is the actual mechanical vvel components did you just hit the boost limit for this car and how could these components be strengthened.

I would defiantly baby baby the car

guess we will find out soon enough...

Anyone know how much it would cost to get stronger pistons and rods?

Not sure who sells them pre-made for our specs, but virtually any company will make you custom rods and pistons if you send them a stock one to copy. Custom forged pistons are probably $600 a set and custom rods can vary heavily depending on specs (H-Beam, I-Beam, A-Beam, manufacturer, material, rod bolts, etc) but are likely $600-$800 for a premo set.

Carrillo makes amazing connecting rods and Ross Racing and Wiseco make strong forged pistons. You should consider though that the engine needs to be rebalanced very precisely since the rotating mass is changing from factory and the redline is quite high.

Just the pistons and rods are listed at about 2k at GTMs website:

GTM Motorsports*::*ENGINE INTERNALS*::*Connecting Rods*::*GTM VQHR Connecting Rod Set
GTM Motorsports*::*ENGINE INTERNALS*::*Pistons*::*GTM VQ37VHR Arias Piston Set 370Z/G37

Its amazing what simple research can do.

:ugh2:
Yeah 600 might work for four cylinders but our v6s run the price up.

^^ 600 what?

Edit: nvm I just realized you were referring to '10Anamoly post, not sure why you quoted me lol

Just because GTM is a grand for the rods doesnt mean everyone is. My buddy had Carrillo make a forged set of a-beam rods for a 3.8 v6 (meaning 6 rods...) turbo firebird and paid $750 total. His pistons were $680 or so from Ross Racing with thermal coating on the tops.

You can pay as much as you want, but its does not mean you cant get quality for less money. You could easily spend $2000 on rods if you wanted to, or you can spend $750 and get a good set too. Quoting common vendor websites or pretending that only GTM's on the shelf options are available is a bit naive, but to each his own.

why are you getting all worked up at me? kosstick asked how much for rods and pistons and I gave him a website with prices for him to get an idea...THAT IS ALL.. Jeeeesus!

Not worked up, just correcting your suggestion that a V6 necessitates spending more than what I quoted, although you certainly can as you showed.

It wasn't meeee it was Equinox hahaha ... take a look, I never said you need to spend X amount, I just provided links :)

Take it to pm's, lets keep his thread clean and on topic.

Side note RON did only provide links but RON please don't take what he said to heart, he may not have ment it in such a way.

lets keep his thread clean get on topic guys :tup:

:tup:

Group hug!

Ok...who added the new tags below??? Hahaha smartas(s)es!

haha thats pretty good

Haha....someone has a sense of humor

p.s. wasn't me

:hello: Hahah u noticed

98Intrigue:

Oh yeah.........so you are looking to go forged internals now? Let me know how that works out. I am planning on building a motor to swap in as well.

Here is my timeslip finally...

And just a fun picture... I spy CSF, Stance, 305s, Shine Auto, Evo-R, and HKS;)

I can get a bottem end for free:tup: It has water damage...everything is fine though. Just needs a cleaning and 1 rod is bent, but I'd build it anyways. So a cleaning and new rods would be necessary anyways.

I'll pick it up hopefully this week or next and have it sit in my garage until I can find some money to build it overtime.

Damn, these tags are cracking me up. hahaha

turbo ftmfw

you can send me your old motor when you put the new one in.. like a recycling program.. after I rebuild your old one, i can pass mine on lol

Send me yours Isamu and I'll stroke it out, and pay mine forward. lol.
