So, back in 2010 my first Z (03 built 18g) lifted the heads when the L17 head studs started to stretch after about 22psi of boost and 40k miles. Well, fast forward to last June I decided to get back into the FI game when I purchased an 06 Touring from a guy in PA that was selling it after the car had been built by Dynosty only a thousand miles ago. The rev up had been swapped for a DE loaded with CP pistons, Manley Rods, and BC stage 2 cams. The 18g turbos had been machined and given 53mm billet compressor wheels by Blouche (i don't recommend using them) with everything being controlled by a Haltech Platinum. I decided to upgrade the clutch to a twin disc and install a Nitrous Express Wet kit. Shortly after I found out that CVVT system was not functioning correctly I contacted Hal at Dynosty and shipped the car to them. Hal, Logan and the whole Dynosty team were top notch. Their communication was amazing and it was just a great experience. FI these cars is extremely expensive excursion and if you are going to spend that kind of money you might as well use the best shop available for Nissan and after 12 years on this platform and seeing shops like MRC, Performance Factory, and GTM just to name a few come and ago, i can without a doubt in my opinion call Dynosty the BEST!!!! The car is an absolute killer on the street!!! Hal kept the tune alittle on the conservative side but still made gobs of power, on 93 at 18psi yielded 618whp, on E85 and 21psi 690whp and E85 21psi and 100shot put down 821whp

Jeez that thing's a beast!

I've only heard good things about Dynosty. If I ever down the FI road, they're the first place I'm going. Beautiful Z man, would love to see a video if you've got any

Nicely done. Congrats and car looks great.

What was wrong with the VVT? A DE only has the intake cams and they weren't working? Usually due to cam sensor jitter on the passenger side. I've had a similar issue but a firmware fix will allow the jitter. I tried replacing cam sensors but problem remains. A capacitor in line with the signal line for that cam sensor might be the ticket to filter out the noise. Haven't had much time to play with it... Since the firmware fix allows the cams to function properly, I've been ignoring it. But I can still see that jitter on logs...

thanks Raj....i wish it was just a firmware issue unfortunately it was mechanical.....at idle valve timing is at 0, as soon as you increase rpm speed and the timing was supposed to advance it would stay at 0...no audible noise of any kind...had plenty of oil pressure to and from the control solenoid and the solenoid was opening and closing..so we removed the front timing cover to find that oil pressure wasn't getting to either cam actuator because of the little fiber rings in the cover were pinched and not letting the oil pass through to the actuators....the oil pressure was putting so much pressure on the fiber ring that it ground down the aluminum....Hal nor myself have never seen anything like it

How bizarre. Glad you both figured it out! Having adjustable CAMs makes a big difference in how the car feels throughout most of the powerband. The first time I experienced my cams turned off (from not syncing on start up), I thought I had blown off a coupler.

I have stressed about those fiber rings ever since sending my rev-up cam covers off to be powder coated. Concerned about effect of baking temps.

Tried to source new rings but the ONLY come new as part of cam covers. I think Rev-up covers were $600 a piece. Found used one off eBay Then stressed about possibly deforming the fiber ring from removing and reinstalling. Would suck to lose an build over such a seemingly small detail.

Back to your build.....I don't rem having heard about ditching a Rev-up for good old De before. I know we discussed cam options for Rev-ups but NOT going with non-revup and Bc 2's which have rave reviews.

Maybe I missed it but was the engine dressed in the pics when you purchased it? Damn it looks great!

enjoy
