MotoIQ Wrench Tip - How to Gap Piston Rings

by Mike Kojima

Setting the gap on your piston rings is an important step to building an engine that performs at its best.  Getting your piston rings to have the optimal seal is perhaps the most critical aspect of good engine building.  Of course you want to spend time assuring that your machine work and cylinder wall finish is correct for the type of rings used but a lot of people neglect blueprinting the ring gap.

The Spoon Sports Center Seat Civic at Super Lap Battle!

by Mike Kojima

We hope you've been following our progress in updating the Spoon Sports USA Time Attack FWD Unlimited Civic here on MotoIQ.  The idea behind this round of modifications was to mildly update the car, improve its safety and reliability, clean up the aerodynamics, and to try some new ideas that will be incorporated into a possible new build by Spoon Sports with the Type R Civic due next year.

Project 5.0 Mustang (The White One) Building the Bottom End

by Mike Kojima

In the last segment covering the engine build on our 5.0 liter Mustang, we addressed the top end with CNC ported heads and camshafts from Ford Motorsports. Now it's time to fortify the engine's bottom end so we can have a screaming high-revving naturally aspirated Coyote engine that is still reliable. 

Our target for this build is to have a safe 8000 rpm redline, wheel horsepower in the high 400 range and run on 91 octane California pump gas with reliability and track car endurance. We feel that this stuff is all pretty easily done.

Tested: KW Suspensions BMW F30 DDC Remote Adjustable Suspension

by Mike Kojima

A few years ago we got to test a sample of KW Suspensions' electronically adjustable DDC coilovers while visiting them at their German global headquarters. We sampled a 3 series BMW coupe on twisty German back roads and on the Autobahn and came away favorably impressed. We were able to easily, and quickly, adjust the suspension from comfortable to firm to match our current driving modd and/or road conditions.

Update: Spoon Sports USA Time Attack Civic!

by Mike Kojima

If you are a Honda fan or a follower of Time Attack then you are probably familiar with the Spoon Sports USA Civic, the little Honda that could. Last year the Spoon Civic with Formula Drift Champion Dai Yoshihara at the wheel, set the Time Attack world on its ear by surpassing the previously thought unbeatable FWD Unlimited lap record for Buttonwillow 13 CW.

Project 5.0 Mustang (The White One) Making it Stop with Essex Parts AP Radi-CAL Brake System

by Mike Kojima

Our Project Mustang came stock with pretty decent brakes. From the factory our Ford features 4 piston Brembo calipers with 355x32mm one piece rotors. However, we still wanted to upgrade our brakes as our much wider tires, 20" wheels, upgraded suspension and engine would stress the brakes a lot more. Our Mustang also weighs a punishing 3700lbs with really cooks the brakes. The Ford factory has put larger brakes on some of the higher end SN197 Mustangs so we figured we should follow suit as well.

Driving Impressions: The CXC Simulator! 

by Mike Kojima

I am not a gamer, I have never liked video games and never gotten good at them.  I have always felt that I don't have the time for them.  I mean, I own a driving simulator chair with force feedback that my daughter plays with when she does Grand Turismo on our home big screen TV but I never got into it and when I have played it, I have always felt that it feels nothing like a car, not enough anyway where I could jump in and drive it.

Building the FR-S FA20 Engine with Stay Crushing!

by Mike Kojima

Our friend Robert Kochis doesn't seem like a typical MotoIQ reader. He is a cool guy, not a nerd. He is into show cars. His daily is a stanced out 350Z that is slammed to the ground and has a ton of negative camber. His other car is a show FR-S with a Rocket Bunny type 2 aero kit. He vapes and has sleeve tats.  He is even super insta famous as Stay Crushing.

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.

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.
