Rebuilding a Nissan R200 Differential to be More Drift Happy with Z1 Motorsports!- Part 2: Tuning the Differential and Installing the Ring and Pinion

by Rathyna Gomer

Where we last left off, we had disassembled, cleaned and inspected all the parts of my differential. Now the fun and important stuff starts- setting up my limited slip differential to work better for the specific demands of drifting. We will also show how to set up a new ring and pinion gear set.

Project 350Z - Testing Jim Wolf Technology C2 Camshafts

by Mike Kojima

So far we have tried some easy bolt ons like a manifold spacer, headers, high flow cats and exhaust on our 350Z all with good results.  Naturally at this point it is time to change camshafts to get more bolt on power out of our VQ35DE engine.  One thing that discourages many people from going this route is that changing cams on a VQ engine is quite a big job. Having two banks of cylinders and 4 cams is a lot of the reason.  It's not super hard technically but it requires at least a couple days of wrenching and some care has to be taken to avoid problems.

Time consuming or not, camshafts are the next logical progression in the evolution of Project 350Z so we asked our friends at Jim Wolf Technology or JWT to provide us with some of their excellent C2 cams.  We chose the C2 because they were probably the biggest practical camshafts that would work in the stock bottom end engine.

Project 350Z- Building a New Engine Part 3

by Mike Kojima

In our last edition of Project 350Z we started to assemble our VQ35DE and got the bottom end pretty much done.  Now we finish off our engine and take it to Church Automotive Testing to get our factory ECU tuned using the UpRev Osiris tuning package.

Project 350Z: Buidling a New Engine - Part 2

by Mike Kojima

When we last left off on Project 350Z, we were in the process of assembling a group of parts to enhance the durability of our project car.  As we stated before we were not looking at building the ultimate naturally aspirated VQ35DE but simply a more durable one that could hold up to a life of track days, drift days and stunt driving practice days. If we could get a little more power out of the engine while we were in there, all the better.

Project 350Z: Building a New Engine - Part 1

by Mike Kojima

Our Project Z was a pretty good example of what a naturally aspirated VQ35DE could do. However, our  VQ had become old and tired. It was worn out from a lot of minimal maintenance street miles, track days, drift and professional stunt driving practice and had started to develop some rod knock.  Luckily we were able to stop before serious damage to the engine internals resulted.  However an engine rebuild was in order. 

Our objective in building this engine is not to build the most awesome NA VQ possible or even to get tons more power, but rather to perform an economic build to address some of the VQ's durability shortcomings, replacing stock parts when necessary with some good quality aftermarket bits.

Project Nissan 350Z UPDATE - New Owner New Plans

MotoIQ Staff Report

Furious 7 stunt driver has taken over the controls (and ownership) of MotoIQ Project Nissan 350Z! Our 350Z project was originally built as a reliable street/track performer, but like any car with an overworked odometer the miles have been stacking up and the original engine finally threw in the towel. It's no surprise either, as it has been in the hands of stunt driver Jay Lynch for almost the past year. Jay has not only been using the car to work on his stunt driving techniques, but Jay has also been using the car to pass down his driving skills to his daughter Brionna Lynch.

Project 350Z - ECU Tuning With Church Automotive and UpRev

by Mike Kojima

If you have been following the progress of Project 350Z as of late we have been testing and running the gamut of  your typical bolt on performance parts to see what kind of gains could be expected for a well tuned but lightly modded VQ35DE.  With an intake, exhaust, headers, intake manifold, cams and valve springs in place, it was time to get into the ECU and tune for our specific combination of parts.

To perform the final touches on Project 350Z we headed to Church Automotive Testing, a licensed UpRev Tuner to have our car dialed in.

Project 350z: Testing the MotorDyne Engineering MREV 2 Intake Manifold

by Mike Kojima

We are reaching the limit of easy bolt on performance gains with Project 350Z.  In looking over the offerings from MotorDyne Engineering, the folks that bought us the intake manifold spacer which made such an awesome difference. we noticed that they had a lower intake manifold plenum available for the VQ35DE that would work for both the Rev-Up and original intake cam only variable cam timing engines.

Project 350Z- Testing the AEM Induction Cold Air Intake

by Mike Kojima

In our last trip to the dyno, we tested  AEM's Short Ram intake on our 350Z.  We were surprised to find a small but definite power increase over another leading intake that was already on the car.  Since AEM makes a long runner Cold Air Intake as well as the Short Ram, we decided to test that as well as an interesting contrast between the two vastly different intake designs.

Project 350Z- Increasing Oil Capacity with Jim Wolf Technology

by Mike Kojima

We have been working on getting more power out of Project 350Z's VQ35DE engine in our latest series of articles.  With success coming bit by bit, we decided that we had to give the oiling system a little help.  Some 350Z's with highly modified suspension and sticky tires have suffered from engine oiling issues when driven on the track hard.  The oil had simply sloshed away from the pickup under hard cornering allowing the oil pump to suck air.  Since engine bearings are made of soft metal and depend on a hydrodynamic layer of pressurized oil to prevent damage, any interruption of oil pressure caused damage very quickly.

Project 350Z - Testing AEM's Short Ram Air Intake

by Mike Kojima

When we first got Project 350Z as a well used and beat up car, one of the mods the car came with was an Injen Cold Air Intake.  Since Injen intakes have a pretty decent rep we simply left in on the car.  However, when we installed the intake manifold spacer, we noted that the manifold was full of dirt and that our engine was a little low on compression for the amount of miles that it had.

Project 350Z - Finding More Power with MotorDyne Engineering

by Mike Kojima

In looking for more low hanging horsepower fruit for Project 350Z, we decided to try an intake manifold plenum spacer from MotorDyne Engineering.  The 350Z's VQ35DE engine has a very thin intake manifold plenum that slopes toward the front of the engine to clear the low hood line.  Although this is good for styling, the engine would prefer more plenum volume and the flow to the front most cylinders is somewhat choked off due to the low overhanging plenum wall.

350Z - Boosting Power With DC Sports and Berk Technology

by Mike Kojima

In the past installments of Project 350Z, we took a look at getting the car's suspension and brakes up to snuff.  With the car handling and stopping well, we turned our focus to freeing up some more power.  Since the car is mostly a budget track day beater, we decided against forced induction options for now because making a high power forced induction motor reliable under continual hot lapping conditions is a somewhat expensive proposition.

To keep a decent budget balance, we decided to focus on some good bolt on's to see what we could get from our 350Z.  For our first step we decided to free up the exhaust side of things with headers and an exhaust from DC Sports and free flow cats from Berk Technology.

Project Nissan 350Z- Making the Chassis fully Adjustable and Getting Rid of Flex with SPL and Whiteline

Project Nissan 350Z- Making the Chassis fully Adjustable and Getting Rid of Flex with SPL and Whiteline

By Mike Kojima

We had last left our Project 350Z with much improved braking at the track with a big brake kit and other parts from Stoptech.  After her last on track foray at Buttonwillow, Sera reported to us that her 350Z was having trouble laying down power out of the turns.  On the gas her car wanted to drift immediately which was limiting how hard she could apply the throttle on corner exit.  The corner exit drift was not smooth but twitchy as well.  When drifting with stock tires, her car was not so bad but with the forces generated by big sticky NT01’s the suspension’s bushings were getting overworked causing toe changes, hurting the car's stability.

Project 350Z- Improving the Brakes with Stoptech

By Mike Kojima

In our last edition of Project 350Z, we upgraded our Wheels and Tires to Motegi TrakLitesand Nitto NT01’s.  When Sera went back to the track she reported much more grip and good basic balance, which complemented the Whiteline Swaybars and KW Clubsports we had previously installed. Now it was time for a Stoptech big brake upgrade.

Project Nissan 350Z: The Birth of our Motegi Trak Lite Wheels with Nitto NT01 Tires

Project Nissan 350Z: The Birth of our Motegi TrakLite Wheels with Nitto NT01 Tires

By Mike Kojima

Our Project Nissan 350Z needs some new shoes.  The stock Nissan alloy wheels had developed a crack rendering them unsafe and the worn generic tires that the car came with were on their last legs.  It was time for an upgrade.  Since we wanted a specific offset and width for this medium powered car we called upon Motegi Racing to provide us with a set of their TrakLite wheels.

Project Nissan 350Z Part 2 - Installing KW Clubsport Suspension and Whiteline Sway Bars

 By Mike Kojima

When we last left off with our Project 350Z we had installed a WPC treated Nismo LSD, an ACT clutch and lightweight flywheel.  Since the purpose of our build is to create an all around fun and practice car for our friend Sera who is a professional stunt driver our next focus is going to be on the suspension.  Sera uses her Z to practice her stunt driving which includes everything from drifting to NASA HPDE’s.  Thus her car has to be adjustable and not too specialized for either drift or grip driving.

Project Nissan 350Z Part One: Installing an ACT Clutch and a Nismo LSD

By Mike Kojima

Our friend Sera is a stuntwoman by trade who does a lot of driving for movies, commercials and TV.  If you see a woman driving in a car commercial, chances are it's Sera. She also does track days with NASA and is into drifting.  She had bought a Nissan 350Z to use as a car to do some track days and also for her to practice her stunt driving and drifting.  The trouble is as soon as she hit the track, she encountered some problems.
