An inside look at the Feal 441 Suspension for the B13 Sentra SE-R!

by Mike Kojima

The original B13 Sentra SE-R has always held a dear spot in many of our hearts. Produced from 1991 to 1994, the SE-R combined the lightweight shell of the Sentra coupe with the sparkling performance of the beloved SR20DE engine. For its time, the SE-R offered a great performance bang for the buck, and to this day, it has scores of hardcore devotees who treasure them.

How To Wrap Your Car with Skyprint Media, 3M and Lamin-x

by Mike Kojima

Paint used to be the preferred and just about the only method of refinishing a race car.  Paint looks nice but it takes a long time to apply and costs a lot to do. In the sometimes rough and tumble world of Motorsports cars end up having to be refinished frequently. 

A lot of guys don't care about how their track car looks and just bang her out so the wheels clear fenders when things get bent. However, sanctioning bodies like NASA and SCCA have appearance rules and if you are sponsored, sponsors expect your car to be presentable so the beat ass race car look wont fly.

Since painting can be a significant expense, any means available to reduce the time and money spent keeping a car looking good is a godsend. One of the ways to keep your car looking its best relatively inexpensively is through a wrap. Wraps used to be pretty hard to apply with mixed results but with new technology, they're becoming easier and easier.

Check out how we wrapped the Dog Car giving it a fresh look with the help of 3M and Skyprint media.

Project Infiniti G20 Transmission upgrades case cover

Project Infiniti G20 Racecar: Transmission Upgrades

By Steve Rockwood

It seems that every time we try to do something to make Project G20 faster, we find a faster way to break something.  This time around, we were certain that while the stock Nissan RS5F32V transmission in our G20 was made of sugar glass, that our modest turbo power levels, stock clutch, and not-so-abusive driving habits should make it last through a season.  After three race laps, we were greeted with the all too familiar sound of a fork in a garbage disposal coming from the transmission.  Someday, we'll learn a lesson the easy way.

SE-R Turbo

Project Nissan Sentra SE-R- $6,000 (video inside)

This folks is about as cheap as speed gets. The old saying goes “Speed is money, how fast do you want to go?” Over the years I’ve spent plenty of money and had lots of fun with the car. But, even the best chapters in life come to an end and the time has come to sell the “Classic.”

Nissan Sentra SE-R- Turbo SR20 Final Build Items

Project  Nissan Sentra SE-R- Turbo SR20 Final Build Items

By Aaron LaBeau

Without a doubt the stage of adding all the little components to a major modification is the part where you can really blow your project over budget. It's also one of the most frustrating aspects because every unique piece must work in conjunction and be reliable. We did our homework and researched what we thought the best parts for the value were while noting our strict requirements for this project.  We'll try not to make this article a boring parts list.

How to Build a Stainless Exhaust with Vibrant Performance

How to Build a Stainless Exhaust with Vibrant Performance

By Mike Kojima

A lot of times a pre made exhaust just wont do it.  You might have a car that no one makes an exhaust for.  You might want to make a big diameter turbo exhaust for a car that never came turbocharged.  You might want to make a special exhaust for your own special requirements.

By Mike Kojima

Fastbrakes is an Arizona company whose claim to fame is making affordable brake upgrade kits for many cars and having applications for niche models like the Nissan Sentra SE-R.  Since some of us race SE-Rs as they are a cheap and sturdy platform, we have a lot of experience with Fastbrakes' upgrade kits for the car.

Project Nissan Sentra Spec-V Part 7: Installing a Turbo System

Project Nissan Sentra Spec-V Part 7: Installing a Turbo System

By Mike Kojima

Since the long stroke QR25DE does not like high rpm, we have chosen to limit its maximum revs to 7000 rpm and make power by adding turbo boost.  Jim Wolf Technology designed our turbo system to produce power over the widest possible range of RPM rather than peak power.  The JWT system was also designed for simplicity, lightness and reliability over maximum power.

Stainless tubular manifold

Project Nissan Sentra SE-R: Fmax Manifold

By Aaron LaBeau

In this third part of our series, we travel down to F-Max Fabrication in San Diego, CA for our turbo manifold buildup. Jhame Peters, owner and fabricator, was ready to take the SR20DE to a new level. His turbo manifolds for Toyota, Honda, Lexus and Nissan engines have proven to make high hp numbers and give incredible reliability. Still, we wanted something better than what was currently available and, at the time, we were willing to sacrifice durability to get better flow from an exhaust manifold. As it turned out, we got a lot more than we were asking for.

When we last left off on our QR25DE project, Jim Wolf Technology was well on the development path for our motor with new rods, pistons and the removal of the balance shafts.  JWT still had a few more tricks up their sleeves to help the motor make more power and to improve its reliability that we will get into in this installment.

Keep Testing Fun: Mike's Day Off!

By Mike Kojima

Bringing you MotoIQ is a pretty tough job, we generally work as much as 80 hours per week which involves writing, layout, photography and wrenching.  On top of that, I am a suspension consultant which keeps me busy traveling and working when I am not here.  We don't get much time off but we love our job and that helps.  We really like driving but we hardly every get a chance to actually drive!

Other stuff we do for fun!

Project 200SX - Track Ready?

By Wes Dumalski

It's no secret that driving your car at speed on a road course will bring to light all of the car's weaknesses. After sorting the motor and suspension we decided to take Project 200SX to a few track day events to put the car through its paces. While the car has proven dead reliable we certainly found its shortcomings.

Project 200SX - Overhauling the suspension...

By Wes Dumalski

We're not going to lie, our old Ground Control and KYB AGX combo might have been good back in the day, but after too much autocross and track time it was showing its years. The time has come to replace it with something worthwhile, the big question we had was what do we replace it with?

Oil Pump Blueprinting

By Martin Gonzales and Mike Kojima

What is as important to your engine's health as your heart is to your own body?  If you guessed the oil pump then you are absolutely correct!  Like your heart, your oil pump circulates the engine's life blood, oil, around to critical components like your engine's bearings and valvetrain.  These parts like parts of your own body would only last seconds without a continual supply of pressurized oil.

Keep Racing Fun, a Fake Blog Road Trip Adventure

By Mike Kojima and Jeff Naeyaert

Warning!  We are not hipsters, we don't wear cool clothes, girl pants, expensive cheap sneakers, fancy hats or carry vintage cameras around.  We are kinda boring so this story might not be too interesting, but if you still want to read on, have fun!  We have been working really hard at the palatial MotoIQ corporate headquarters.  We have been out covering events and working on project cars nearly every day.  Too much work and no play makes for even duller nerds so we decided to hit the road to enter Redline Time Attack's round 3 in Las Vegas.

MotoIQ Project Sentra Spec V

Project Nissan Sentra Spec-V part 5; Lessons in Geometry

By Mike Kojima

Although Nissan hyped up the Sentra Spec-V as a performance sedan in its marketing campaign, in truth the car was a little more than a piece of basic transportation with a few performance enhancing bells and whistles.  The car was cursed with a crude beam axle rear suspension and a McPherson strut front suspension whose geometry was designed around efficient packaging and relentless understeer rather than performance.  Because of this, the Sentra is at a significant disadvantage in the handling department when compared to its FWD rivals, mainly Hondas, the Scion TC and even the Infiniti G20.  Despite of all this, we at MotoIQ are always up to an engineering challenge and we set about to rework the SE-R's suspension to attempt to make it a little more competitive.
