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!

Gary’s 500hp Twin-Turbo G35

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 2:07 am on February 10, 2011

Gary S. must have an affliction for Nissans that are fast, black, and modified. This 2006 G35 Coupe has just 13k miles on the clock and it has been tastefully modified to the tune of 500+rwhp. He is also the owner of the black BEHEMOTH RB28 240z, and brilliant S14 240sx (not black) that I will report on shortly. There has got to be another black, high hp Nissan somewhere in his garage 🙂 Besides owning fast Nissans Gary is quite resourceful and creative. Notice those ZCarGarage-themed barstools in the shop office? See a bunch of hard to find JDM pieces on wall? Thanks Gary!

When we last heard about Gary’s G35 it was making 470whp/470tq on 91 octane with the APS TT kit. The built engine comes from Rebello Racing and uses JWT S2 cams, 650cc RC injectors, 3.5″ downpipes and a JWT flywheel with HD clutch.
We were having trouble holding the boost level steady so upgraded Forged Actuators(13.5psi) and an HKS EV6 Boost Controller were installed to keep it in check. UPREV tuning with a PMAS MAF showed that stable boost = BIG HP and TQ: 513hp/509tq to the wheels!


Here is a short video clip(more to come) from one of the tuning sessions:

When Gary isn’t driving his amazing S14 he swaps out for this big, black machine with massive Stoptech brakes gleaming through gunmetal spokes of the Volk GT-7 wheels. Gorgeous .

This is the year that Gary will finally drive the long awaited BEHEMOTH so keep following the blog!




Black 280z Restoration…Chassis Update

Filed under: 280Z,Featured Cars and Projects
by Alvin G @ 1:04 pm on January 20, 2011

The slick black paint on Gary R’s 280z makes me drool. Then my eyes widen when I see the gigantic ZCG BigBrakeKit AND new Panasport wheels.  This is just a mock-up, but I can’t help but feel excited! The restoration moves forward with all of the newly plated parts and suspension being installed by Josh C. Hydraulic/fuel lines were beautifully plated in gold(brake) and silver(fuel):

The engine bay is glossy and the firewall is gleaming!

In our last update the interior and entire underbody was stripped and treated with POR-15, seen HERE. After drying, the front and rear suspension is in place with struts/coil overs mocked up. Note additional plated hardware:

Here are some shots of the coilovers and ZCG Big Brake Kit in all its all glory. Wheels/tires are 17″ Panasport C8s with black spokes and 255/40/17 tires under stock flares:

Stay tuned for our next update as Gary’s 280z gets a drivetrain!




Happy Friday From Z Car Blog

Hello Z car fans,

As ZCG gets ready to leave for the ZONC Hearst Castle Cruise, we have a Blog entry from Bill (a Z car fan and spirited driver).  He gives us a full report from his last track day at Infineon Raceway.  Have a great weekend and don’t forget your Valentine’s day card for your special someone.

Long live the Z

Rawb

 

The photos and videos are from Hooked on Driving’s January 27th track day at Infineon Raceway in Sonoma.

This 2003 350Z Touring model has seen a handful of track days. It started going to the track on the stock 1-piston brakes and street tires with only a few upgrades: Stillen dual exhaust and AEM cold air intake. Recently added (from ZCG) were StopTech’s small front and rear brake kits with Performance Friction 97 pads. This was the car’s first event on track tires: 245/40-18 BF Goodrich g-Force R1s on the original 18″ wheels. Track tires with tire pressure monitors! The car is otherwise stock (with heated leather seats to take the chill out of winter track days). Despite the upgrades, this is not a track-only car. After swapping back to street tires, it handles the daily commute to and from work.

Infineon is a very technical track, which is challenging but makes for a lot of fun. It has elevation changes, two hairpin turns and the famous esses. The track was wet in the morning. There were a few spins and other incidents, including this car’s slide off the pavement at turn 3a (notice the mud on the left front tire). Nothing hurt but the driver’s pride. A wet track really helps a driver learn to be smooth, a very important part of going fast when the track is dry.

The sun came out in the afternoon and speeds went up. The driver reports that the tires are great, but the StopTech brakes are amazing! With the track pads and regular bleeding with high-performance fluid, they haul the car down from speed over and over without a hint of fade; a huge increase in braking performance over the stock brakes.

This video is from the last session of the day in the intermediate group. It starts out with a few laps of lead-follow with an Audi S4. This run group started out small and by this session, many drivers had packed up for the day, leaving very little traffic. Gotta love having room to roam!

Hooked on Driving, a longtime ZONC supporter, is well known for putting on quality track events. With a strong emphasis on education and safety, it’s a great place for beginners to get started. The event prices include a catered lunch and individual coaching for beginning through advanced drivers. At noon, the coaches fire up their own cars and give beginners hot laps around the track. Big fun! Their web site, www.hookedondriving.com, has lots of information and videos for first-timers.

Even though most of this blog’s track day posts feature modified cars, a stock Z33 is a great track car if properly prepped. Track prep is not complicated. It includes checking the wheel bearings, lug nut torque, belts and hoses. It might also include replacing old brake fluid to help the brakes handle the higher temperatures generated on the track. ZCG can take care of prepping your car for the track.

Please note that in addition to providing full-service maintenance and upgrades, ZCG can also supply parts for do-it-yoursefers. This car’s StopTech brakes were sourced from ZCG and installed by the owner.




More Track Day Prep: StopTech Rebuild

Filed under: Featured Cars and Projects,Maintenance,Performance
by Forbes @ 3:44 pm on December 26, 2009

You all have seen this car here before and I’m sure you are aware of it’s on track antics, if not then see the links below for a refresh.

This car sees tons of track time.  In fact it pretty much only sees track time, and like most track cars, after awhile things need to be refreshed.  In this case the StopTech Big Brake Kit was in need of a few new parts to prepare it for the Norcal UFO trackday the following weekend.

As you can see from the pictures, the hats for the two-piece rotors have seen some massive heat.  Enough in fact to destroy the original black anodizing.  These parts, while discolored, are still perfectly functional.  The rotors on the other hand had seen better days and were replaced with new ones.

The other part of this rebuild comes in the form of replacing the main seals for the four pistons in each caliper.  From the pictures you can see that the old ones were covered in debris and brake dust and were starting to weep, not a good thing when a race car relies on repeatable pedal pressures for optimum performance.

The seals were replaced with the new gray pieces and the entire system was reassembled and given back to the owner just in time to thrash on it at the Thunderhill Raceway.  Pics of the track event are still to come and are well worth the wait.

See all the photos of the entire rebuild after the read more (there are 30 or so)

Merry post-Christmas
