Chris Berry has one beautiful G. He’s brought it in several times for dynoing and AT valve body upgrade. It has a plethora of mods including a Vortech SC and Cosworth Intake Manifold.
Clean enough to eat off but why make it dirty doing so?

Jesse brought us his clean G for some fine tuning. No surprise that this car was running uncomfortably lean. After some tweaking to not only AFR we came up with some nice gains.
Good solid gains of over 11 whp and 10 torque.
This JDM rockin’ Z33 is a pantie dropper for sure. Sporting Seibon C.F. fenders, Volk TE37s Seibon Edition Wheels, and other assorted C.F. ware.
Under the hood it has a gnarly whine that suggests it isn’t all show. A Vortech snail resides under there willing to boost it with the rest of the mean machines in our shop. Along with Stillen Headers, factory CATs, and HKS Catback. Vithorauk (the owner) called on us to tune his Z machine for optimum radness.
Luckily for him he laid off the gas pedal until it was tuned. It came to us with the UniChip piggy back. It was a no brainer to yank that thing outta there and get the party bumpin’ with UpRev hawtness. After swapping out the factory plugs with colder ones and inspecting a few other things it was time to make some boost. The baseline run with the UniChip had to be prematurely aborted due to unwanted mean and way too lean AFR. A damn good thing Vithorauk never laid into it. After some much needed massaging this baby was ripping it hard. One thing about superchargers is that they do sound f-in mean. Especially in our dyno room.
The before & after transformation…………….
Self explanatory……the blue run is the baseline on how it came in and red is where it came out rockin’ it hard. Smooth power delivery and some sweet AFR to go with it (red run). We made 369 whp & 308 torque with 7 psi of boost. Props to Anthony @ Antelope Valley Nissan for a job well done in the installation department ( I didn’t have to redo much).
Juan from Bardabe brought over his 2007 350Z MT HR for some basic pulls and left with more power and a safer car. Looking at his baseline dyno (in blue) it was way to lean to do a full pull. His Z had his custom cold air intake, test pipes, and catback.
I don’t remember what catback he’s running (Greddy?).
We ended up with 293 whp and 261 wtq.
Last week Brandon brought over his black beauty AT 370Z for tuning. This Z34 comes equipped with F. I. Long Tube Headers, F.I. C.F. Catback, Stillen UD Pulley, and Stillen Gen 3 Intakes. Brandon knew better than to go flooring it until the car was tuned. Make sure to at least check air fuel when doing engine breathing mods. Many of the intakes out in the market will lean your mixture.
Peak power didn’t go up drastically, but everything where it counts below that made an average of 10 more whp and torque from just tuning.
We took this daily driven Z32 owned by Jason & Nikki and injected it with some good ole fashioned mods. Believe it or not this car started out life as a 5-speed and was converted to accept an SZ Stage 1 Automagic Trans. This Z32 posses’ a “fresh” JDM engine with the auto A\R turbos (smaller than 5-speed turbos). When the engine was dropped in we dynoed the car to see how it performed with factory boost levels, full SZ 2.5″ exhaust, and single POP. We then added our SZ 3″ Downpipes, SZ 3″ to 2.5″ Test Pipes, JWT Dual Pop w\ Selin Translator, Blitz SBC iD-Spec-R Boost Controller, and SZ custom tune. It still has factory intercoolers too.
Turbos are truly an amazing thing. Boost and Zs rule! Like my bud Rob Fuller would say. You can see the “before” and “after” results below.
Say “ahhhhhh” (At the doctor’s office)
That’s right folks, almost 100 RWTQ gained by 4000 RPM. Time to shred some tires and laugh at Prius owners! For those who have trouble reading a dyno graph, the red lines are the “before” runs and the blue lines are the “after” runs. The fainter of the lines are Torque and the darker are HP.
Dean finally got his Z tuned this week. We’ve been so busy over here at SZ that we didn’t have a chance the last several months to get his monster the proper attention required. His mod list can be seen here: Dean’s Mod List
He plans to make the upcoming June 12th IDRC event, competing in the True Street Class. The dyno graph below shows his race fuel tune on boost and also on nitrous. One can see how well the nitrous works, it is only used to get out of the gate and shuts off at 5500 RPMs. This should be enough to get him into the 9s. Now go kick some ass!
No, that’s not Dean with the pot belly.
Luis brought us his Z33 AT for a few goodies and ultimately for a tune on his basic NA DE. His Z has plenum spacer, catback, resonated test pipes, Nismo C.A.I., and UD pulley. Needless to say his AFR was way out of whack. So far so that we felt it was unsafe to get a complete baseline pull. A week before this we made a few baseline pulls on another Z33 that only had a JWT POP for a mod and was running extremely lean as well. The JWT POP on the DE engines doesn’t change the sampling tube diameter of the MAF so the intake alone isn’t causing the AFR to be lean.
Here’s Luis’ results:
His base AFR (blue pull) was in the 13s and 14s! After some tweaking we ended up with a safe AFR and a much peppier Z. We gained over 25whp in certain areas.
Where do we begin this story? Well its a long one and there’s no need for specifics. We can say it has a happy ending. I hope that didn’t spoil it for ya ;). Dave brought us his red gem child from the big state of Texas for some fixin’ after the wrench hit the spokes in his prior builds. Along the way to Z nirvana, this Z received some funky fresh mods. It arrived at our door with a freshly built engine, larger CZP 2560R turbos aka “GT28Rs”, MSP Manifolds, SZ 3″ Down Pipes, Nismo “old skool” 555cc Injectors, JWT 400 cams, JWT Dual POP, etc… (the important mods). We performed various seances to rid the evil spirits and added SZ 3″ to 2.5″ test pipes and SZ 2.5″ dual tip catback. It had that nasty ole’ Borla catback and 2.5″ test pipes (good riddance). Added some CZP silver I\C piping, Ash Massives, and Z1 T.B.s to round out the “charge” side.
The Z was dynoed back in Texas before we got our hands on it shortly after its latest build. Depressed with the paltry results of 365 whp, its owner decided for drastic measures.
Loaded with some Texas 93 octane we kicked off the dyno tuning fun. I forgot what “real” fuel smelled like from other non-smog Nazi states. Hell would freeze over if California got 93 octane one day. Its amazing how 2 octane points help. Luckily we have quite a few local gas stations that offer 100 octane at the pump.
A little cleaner.
Just another day at the spa.
Here’s how the Z performed on 93 octane & Q16:
510 whp & 465 torque on Texan 93 octane and 587 whp & 545 torque on Q16.
In a week or two this Z will be on a trailer to go back to her owner. Enjoy the ride!
John, in the last year or so has brought his beautiful Z32s over to us for tuning. His yellow Z has Sport 700 turbos, IPP engine, stock cams, MSP Manifolds, Nismo 740cc injectors, SZ full 3″ exhaust, Z1 TBs, CZP I\C piping & Ash Massives, and dual POP with Selin elbows. All available from our new store. John did the work himself and did an excellent job on both cars. Better work than I’ve seen from other pro shops. Two thumbs up! John has the help from his son Connor when it comes to working on the Zs. Connor has been an integral part of John’s SZ trips. Connor also lends a hand around SZ if needed. This last time John brought his family to enjoy some of the SoCal sights.
The Zs soaking up the rays in SoCal beach weather.
His red Z is equipped with Sport 530s, Nismo 740cc Injectors, MSP Manifolds, SZ 3″ downpipes and test pipes that cone down to 2.5″. Stock I\C piping, Stillen Intercoolers, and dual pop round off the majority of the engine mods. You may notice he has a roll bar in this Z. John plans on participating in some local AZ time attack events. Both of his Zs are running proto SZ MAP sensors. No MAFs on these Zs. Nice since his yellow Z has BOVs. This is one of the new products we’re working on in the near future. There’s still some more work tweaking to be done.
Clean execution from Yellow Bird.
Blue is 91 octane, Red is 100 octane, and Green is Q16.
The Red Phoenix. More sleeper with a hint of SPL Coilover Blue.
Blue is 91 octane and Green is 100 octane.
