240sx Update: Brakes, Turbo, Tuning

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 1:46 am on February 18, 2011

Gary S. is a guy on a quest…to own each example of Nissan perfection. Lets begin the next chapter in Gary’s 240sx as it gets closer to that vision of exellence!
With the G35TT being what it is, Gary’s back-up car must have the same 3-dimensional qualities of big power, big brakes, and suspension. The to-do list included cleaning up the work done by the previous owner, and improve on an already amazing ride.
When the 240SX arrived from the east coast it already had the SR20DET engine swap, stock MAF, stock turbo, and boost controller. We dyno’d the car in stock configuration: 205hp/193tq at the wheels indicated a clean bill of health. Let the modifying begin.

We made a plan to make nice power on 91 octane with big torque throughout the mid-range to help Gary forget his new ride only has 4 cylinders 🙂 We installed a more “adult” exhaust to replace the loud RS*R muffler. Made by BRM, this exhaust is fairly priced, has perfect fitment, and most of all the twin-tips look very close to the factory outlets!


A call was made to Clark @ JWT and we wired in the Z32 MAF, installed the NISMO 740CC injectors, and plugged in the new ECU upgrade from JWT. We knew the stock turbo would never meet the power and torque requirement…come on it’s Gary…So another call was made, this time to the folks at TOMEI USA:

We decided to run several TOMEI components so off came the valve cover to install the S14 Poncams, rocker stoppers, TOMEI Expreme stainless turbo manifold, and turbo outlet pipe. TOMEI had just released the M7960 turbo and we told them we would give it a try and report back on the performance level. Behold the turbo manifold in all it’s glory….before it gets wrapped with high temp tape:

The stock manifold + turbo vs new Tomei setup….Hey Gary that old T28 is going into Alvin’s roadster, right?


Once the parts were installed we ran the Wideband 02, plugged in our Consult II and went out for a test run. The MAF voltage was higher than I had ever seen on a turbo car at this boost level. Once the boost kicked in…it was enough to put you firmly back in the seat.
On to the dyno…power levels were very nice, but at the top of the rpm range we were having trouble holding steady boost. 338hp and 305tq to the wheels with a great powerband was nice indeed.

We checked all of the usual suspects to sort out the boost issue but no answer. TOMEI USA was contacted and they are willing to help us find a way to get the desired power with a steady boost pressure: To be continued…

…Back to the car…
Big power is a great thing but driving a car that can only go fast can get old very quickly. It is no secret that ZCG loves using Stoptech Big-Brake-Kits…we have tested them on the street and the track with impressive results. It’s about time serious hp power met serious brakes on these cars! When was the last time you saw a set of these on a 240sx 🙂 Larger rotors, stainless lines and appropriately sized master cylinder round out the upgrade. To match the front calipers the rear Z32 calipers were finished in red/white lettering:

The 240 already came with a sweet set of bronze 18″ Nismo LM-GT4 wheels, here is the before/after Stoptechs up front:

Of course the bronze looks great against the white body but Gary wanted a more low-key appearance so the wheels were re-finished in black:

The next steps in the 240SX project will be to sort out our boost issue,  install some suspension upgrades and gauges. Here are a few more pics of the car with the new look:

Long Live the Man With The Most Nissans!

Amir’s Clean ’91 300zx

Filed under: Featured Cars and Projects,Maintenance,Performance
by Alvin G @ 1:14 am on February 4, 2011


A few years ago I noticed a super clean white 300zx (NA) with tan interior always parked in the garage at my work. It made me excited to see another Z brother and I wanted to meet the owner or at least leave a “nice Z!” note on the car because it was in such good shape. Eventually I met the owner, Amir, at a conference and turns out that he has always been a fan of the Z32 since it was released in 1990! I mentioned ZCarGarage to him and soon enough this pretty Z32 was getting some love at the shop.  Amir’s Z came to us with 114k miles on the clock and virtually no major problems during it’s ownership. Routine maintenance was performed and a few choice performance parts were installed including:

-Powertrix tension/control arms
-SpecialtyZ exhaust system
-Twin-Turbo Z32 wheels
-power steering hoses
-timing belt service
-full steam cleaning of the underbody

 

SpecialtyZ exhaust system:

 

Powertrix parts:

 

New tension rods installed:


The dyno revealed impressive numbers for this 20-year young Z.  197hp/184tq at the wheels for a bone stock engine with 114k miles!

 

We have a feeling that Amir might have caught the mod-bug so stay tuned for more pictures and updates.

Long Live the Z32!




Z Are Family (Part1)

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 11:34 pm on November 10, 2010


You know its true love when your wife drives a Z . Ashley took a trip out of town and while she was gone her sneaky Z-obsessed husband dropped her ’07 350z off for some ZCG love. A family that Zs together stays together.  First item on the list for this visit was a baseline dyno to see what we were working with, then a quick install of dual JWT Pop Charger air intakes:


The VQ35HR engine responds well to minor bolt-ons and the addition of JWT intakes resulted in an impressive gain of 17hp/13tq! Plus they look great and sound heavenly when Ashley leans on the loud pedal.


Ashley’s Z sports a set of SSR GT3 wheels with stock ride height. Every Z can benefit from a little lowering, especially with aftermarket wheels/tires.  TEIN S-tech springs were called upon to give the Z a mild drop. Pics coming soon!


The last detail was a set of LED side markers that are both stylish and functional for when Ashley needs to switch lanes and pass the slower traffic 🙂

Stay tuned for Part 2 of “Z Are Family”




Palo Alto Concours D’ Elegance…Pictures!!!

The Concours event was an amazing experience. Big thanks to David Swig for the invitation and giving Japanese classic cars a presence at the show and in people’s hearts!

We left ZCarGarage at 7am with three 240z cars, a ‘67.5 roadster and one sinister-looking s/c’d 350z.

This was my first time at a Concours event, and I was really impressed with how the venue was organized. As we drove  past the registration and onto the lawn area each car received a bottle of wine!  Flag wavers at every turn directed us to our staging area, where I immediately saw a sea of Ferrari’s and other exotics. I kept wondering, “A bunch of Datsuns get their own display in this show? ” Yes indeed. Not only Datsuns, but Hondas and Toyotas deserve their moment in the spotlight as well 🙂

The Japanese classic car display included a Toyota ’67 2000GT,  Toyota Sports 800, ’68 Honda S800, ’71 Skyline GT-R.   3 Datsun 240zs,  Datsun roadster, and a 1973 Toyota Corolla.   9 lovely Japanese cars in between gangster-era Cadillac’s and bright red Ferrari’s.
 
 

 

 
People were smitten with the display. I could hear memories being conjured, stories being swapped. It was great exposure for our cars, and quite endearing to see this happen amongst all of the high dollar iron surrounding us 🙂

                    
Rob told me that the Skyline was real, with the S20 drivetrain. My jaw dropped and I got very giddy as I have never seen a real Skyline GT-R in person. When the owner opened the hood the mighty S20 gleamed in all its twin-cam glory. Check out the pictures below for more detailed shots…from the underbody to the interior, it was a treat.
                  

The arrival of summer came late to the Bay Area but it was definitely felt with 95 degree + temps. Multiple tents and water stations were available to the attendees. Our invitation included snacks, drinks and lunch in a pavillion with a perfect view of the car display ramp. We were fortunate to have a chat with David Swig about seeing more folks getting into vintage racing and increasing Japanese car representation.
    

Here is a sight that was new to me: Concours judges scrutinizing cars. Maybe one day these gentlemen will be judging your Nissan/Datsun at a Concours event! Why not?


After lunch it was time to check out more of the cars, and I can’t describe or include all of the wonderful machines so I will  list a few favorites. Make sure to click after the “read more” to see all of the pictures!

Mercedes Benz 300SLs, and Gullwings galore! The new SLS was there too.

This Alfa Romeo Guiletta Sprint had just the right proportions:

Chrome everywhere, huge grilles, hood ornaments, and interiors that are so huge and luxurious that they belong on Lifestyles of the Rich and Famous

           

The event was truly an incredible experience and hopefully we can have an even greater display of Japanese cars for the collector car world to appreciate. Enjoy the pictures!

24 Hours of LeMons Report from Bill N.

Filed under: Events
by Alvin G @ 2:33 am on June 15, 2010

Costumes and decorated vehicles. Sounds like a parade? Ummm…sort of. It was actually the May 8-9 running of the 24 Hours of LeMons at Thunderhill Raceway Park in Willows, CA. This is a nationwide endurance race series for $500 cars. Teams must purchase and prep their vehicles for no more than $500. The limit does not include safety items like roll cage, brakes, wheels and tires. This event was 16 hours of racing over two days. Some LeMons events are a full 24 hours.

Teams “themes” are part of the fun, but the series is so popular that a good theme is often needed to get a team accepted to an event. This race included:
Two Starship Enterprises

A Supra with Tiger and Elin Woods on the roof

A Ford Ranchero wagon (built from an E-30 BMW)

And a beautiful 1958 Plymouth Fury (also built from an E-30 BMW)

There were many good drivers, but also many with little or no track experience. To make the race as safe as possible, the series prohibits even a hint of poor driving. Putting two or more wheels off the track, tailgating, not allowing faster cars to pass, spinning, etc. will get a team black flagged, whereupon they must go to the penalty area. The penalties, however, are hilarious. They might include writing a phrase on the car 100 times, reading a passage from a book “revival preacher style” to their team, or the parading through the paddock confessing their on-track sins. Regardless of the type of punishment, they keep the perpetrators off the track while the rest of the field adds to their lap count.

The bad news: Z cars typically don’t do well in this series (I think it’s because Z cars are so cool they need to be in pretty sad shape mechanically to fall to a value of $500). The organizers award a special prize, the Z Cup, to the Z car team that does the least poorly. This event’s prize went to The Underground from Tempe, Arizona, driving a 1985 Nissan 300ZX Turbo. They finished 19th out of 108. Not great considering the 18th place car was a Mazda 323.

The good news: This event’s winner was a Nissan. The winner on laps was team Rogue Squadron with their Star Wars themed Nissan SE-R. Way to go!
