Attacking Time with the LYFE Motorsports Nissan R35 GT-R

by Mike Kojima, action Photos by GTA and Snap Studios

When Cole Powelson set out to build an R35 GT-R he initially didn't have the ambitious plans to build one of the world's fastest time attack cars. The 2012 GT-R originally was built as a modified but streetable time attack car which was run for fun.  Then the car was repurposed and underwent a metamorphosis, eventually being rebuilt into the sophisticated machine that appears on our site here.

Lessons in Turbo Technology with Garrett - Burst Containment

by Mike Kojima

What is burst containment for a turbocharger and why is it important?  A turbocharger is a system that has a lot of potential to cause a lot of bad stuff to happen to drivers, spectators, and surrounding equipment.  Why might you ask? Well, a typical turbocharger can spin at up to an unfathomable 200,000 rpm for a small frame turbo and a still amazing 90,000 rpm for a large frame turbo!  That is a ton of potentially ass-kicking force. We will show you how much later and it's enough to make you cringe.

Building a NASA NP01 Prototype the Right Way with Stoptech! Part 2

by Mike Kojima

Ever since we laid eyes on the conceptual drawings and parts of the NASA/Elan NP01 at the PRI Show 2 years ago, we have been enamored by it.  Since we have loved the exotic cars in the various Prototype classes throughout history, we saw the NP01 as the affordable Prototype.  The fact that it looks like a contemporary P class car seals the deal!

Building the Naturally Aspirated Honda K Engine!  Part 1

by Mike Kojima

The Honda K series of engines is one of our favorites and one of the top production inline 4 engines ever produced in our opinion.  Last year we built a turbo K24 Z7 for a giveaway by Motovicity.   With the turbo project being put to bed we got another opportunity to build a K motor in the form of a naturally aspirated K24 Z7.

Project G20 Race Car: Building a More Bulletproof SR20DE!

by Mike Kojima

The good old stock SR20DE in our Project G20 Racecar has been doing yeoman duty, reliably lasting for the last few years racing in the MotoIQ Pacific Tuner Car Championship and doing many for-fun track days.  The stock SR20DE in our Project G20 Racecar came from a Japanese engine importer and has never been opened up, other than to add big cams back when we used to run the car in N/A trim.  For the past three years the engine has been turbocharged which has greatly increased the strain it's experienced.

Fixing Fuel Starvation with the Holley Hydromat

by Mike Kojma

Fuel Starvation is almost always an issue when a high performance car is driven on the track, especially on production cars modified for racing.  Factory type fuel pickups are woefully inadequate for a car with modified suspension and sticky tires when driven on the track.  Just about all of us have been victims of a sudden loss of power due to fuel starvation when cornering hard.  A lot of us have had close calls because of this.

5 Performance Car Engines That Suck!

by Mike Kojima

We are going to go out on a limb and make a lot of fanboi's angry. They will call BS and burn us in effigy.  However we are still gonna express our opinions which were developed over the years in the school of hard knocks and talk about real issues we have seen when racing and developing many of our industries' favorite and even legendary engines. Now don't get us wrong, these engines can be turned into successful racing platforms when some major engineering and big dollars are applied but a lot of it is beyond the easy to figure out, easy buy and bolt on stage that most street tuners dream about.

PE Engineering's Racing Pedal Box: The Easy To Install Pedal Box

by Mike Kojima

When building a race car, the only way to get true brake proportioning is to install twin master cylinders and a balance bar. If you are not familiar with this sort of setup, we're talking about having a master cylinder for the front brakes with a separate master cylinder for the rear brakes.  The brake pedal activates both master cylinders at once through a threaded rod or balance bar.  As the balance bar is turned, the brake pedal's fulcrum point moves right or left which gives the brake pedal more leverage on the front or rear master cylinder thus adjusting the proportioning.

Project IS-F: Evaluating the Nitto Motivo Tire

by Mike Kojima

Our Project IS-F is still around, it has been quietly and reliably racking up the miles doing daily driving duties in and around Orange County.  Our car is driven at about 70% street driving and 30% highway driving. One thing we have noticed is that the car has a healthy appetite for tires even though the car is used mostly for family transportation duty. For instance, the factory Michelin Pilot Sports were gone after only 11,000 miles.

The Alley: Enrique Perez's LS-1 powered TE72 Toyota Corolla

by Mike Kojima

In keeping with our new tradition of using our secret photoshoot location behind the palatal MotoIQ Mega Shop, our next Alley feature is a very special car. Enrique Perez's 1980 TE72 Toyota Corolla. The TE70 series Corolla produced from 1978 to 1983, is one of our favorites as it is a classical Corolla with a front engine and rear wheel drive.  Much of our youth was spend modding these cars.  With their near bulletproof 3TC engine they could take a lot of hard use and we spent a lot of time boring them to 2 liters, strapping on dual sidedraft carburetors and hosing them with Nitrous Oxide.

Evaluating HKS Hipermax SP coilovers on the Mazda ND MX-5

by Mike Kojima

The Mazda ND MX-5 is the latest evolution of the Miata chassis.  We have found it to be an excellent handling car, one of the best and most well balanced cars we have driven.  We have, however, found the car to be too soft in completely stock form to really be fun.

Lessons in Turbo Technology with Garrett!  Lesson 1 - The Compressor Wheel

by Mike Kojima

Recently we were privileged to be able to take a look behind the walls of Garrett Turbochargers' research and development facilities.  We were able to get an insider view of the intensive engineering inside a Garrett Turbo and viewed first hand what differentiates it from your typical aftermarket fare.  We were very impressed by what we saw and we would like to share it with you by breaking some of what a World Class OEM supplier puts into the performance turbos any consumer can buy into easily digestible lessons that we will be presenting to you periodically. Perhaps the key part of any turbo is the compressor wheel.  Let's look at what Garrett does to bring you one of the best compressor wheels on the market.

Building the Subaru VA WRX clutch and Flywheel with ACT!

by Mike Kojima

All wheel drive cars are traditionally hard on clutches. With tons of traction, launches involve a lot of clutch slippage. Fast shifting and even downshifting are all harder on the clutch due to the increased traction of 4 wheels.  With this in mind building a daily driver heavy duty clutch for a street car is always a challenge. 

It just so happened that our friends at ACT were wrapping up development of a clutch and flywheel combination for the late model VA WRX when we were at their office and we thought it might be a good opportunity to show what is deep inside ACT's WRX clutch which shares many design features with all ACT clutches.

Happy 4th of July Weekend!  From the Staff of MotoIQ

Remember when we were in Peru visiting Machu Picchu? We're still showing our support for the greatest fucking country in the universe.  Instead of being "Ugly Americans" we thought we would pretty up this historical site a little... 

Happy 4th of July!

Nerd's Eye View: The Dyson Mazda ALMS P1 Prototype

By Mike Kojima

I am old enough to have been around during what I consider to be the golden era of American road racing in the 80's.  In this time we saw the rise of IMSA with the outrageous GTP prototypes and the exotic sort of production based GTO and GTU cars.  SCCA had Trans Am and even CART Open wheelers were sporting awesome technology rivaling Formula One but with closer more exciting racing.  I was lucky enough to have been a fan during this time and later on in the decade a participant.

Building a NASA NP01 Prototype the Right Way with StopTech!  Part 1

by Mike Kojima

Last November we had the chance to drive and evaluate NASA's NP01 Prototype built by Elan. We loved the car and eagerly awaited its availability. Fast forward a few months and our friends at StopTech were able to get one of the first NP01 kits.  Since StopTech's facility was undergoing expansion it was agreed that the car would get built at the palatial MotoIQ mega shop and that we could do a series of articles on what it takes to build a winning NP01.

Improving Towing Capability with Hellwig and Bilstein Part Two

by Mike Kojima

In part one, we had installed Hellwig air springs, rear anti sway bar and Bilstein 5100 series shocks on our workhorse 2014 Chevy Silverado truck.  We were super impressed with what the rear suspension did to make our towing experience more pleasant and much safer. However, due to time constraints we did not have time to do the front suspension.

Mucking Off with Muck Daddy, Green Style

by Mike Kojima

There is always plenty going on at the palatial MotoIQ HQ.  A lot of that involves race cars and high mileage street cars.  This means that we're constantly dealing with dirty and grimy hands of the worst order.
