by Mike Kojima, Photos & Video by Jeff Naeyaert

Way back when the third and final installment of this build was part of our best of 2010 series. It's still a great article presented here for you to check out one more time. Follow the links, read all three parts and enjoy!

When we last left the Technosquare crew, they had completed the stroker 4AG engine's bottom end and assembled the cylinder head.  Now it was time for the engine's final assembly and installation into an AE86 time attack car.

Extreme Engine Tech: Technosquare's Monster Naturally Aspirated Toyota 4AG - Part 2

by Mike Kojima

In our last edition of the building of Technosquare's monster Toyota 4AG, we mainly looked at the details of the bottom end.  Now we will finish our tour of the bottom end and delve into the engine's cylinder head which is the heart of any high performance engine.

The 83mm x 83 mm stroker motor gives 1800cc.  The 200 extra cc's makes a huge difference, fortifying the 4AG's notoriously narrow power band. The engine cranks out over 250 crank hp, more than the most highly developed Formula Atlantic engines of yore and 30 more hp than the previous 1600 cc version of this motor. Here it is, re released again for your reading pleasure!

Technosquare Howard Watanabe 4AG Engine Build

Extreme Engine Tech:  Technosquare's Monster Naturally Aspirated Toyota 4AG - Part I

by Mike Kojima

The Toyota 4AG is a historic engine, one that was essential in launching sport compact car culture in the USA.  In 1985 the 4AG first rocked the automotive world.  It was the standard engine in the Toyota Corolla GTS, the famed Hachi Roku AE86.  The AE86 was the last of the RWD Corollas and Toyota made history by equipping it with the revolutionary 4AG engine.  Not to be forgotten, the AW11 MR2 mid engine sports car was also powered by the 4AG.

Sneak Peek: Bothwell Motorsports Pro Mod Camaro

by Khiem Dinh

The Bothwell Motorsports Pro Mod Camaro plays in the National Muscle Car Association drag racing series where it won the West Division in 2014. The series mandates engines that are either small block or big block V8s with power adders being nitrous, roots blowers, centrifugal blowers, or turbos. You know us at MotoIQ, we like turbos. A pair of turbos is even better.

Saving (Lots) of Weight with a Pegasus Racing Ballistic Battery

by Mike Kojima

"No way is this thing gonna start the car" is the first thing we said when we opened the box containing the Ballistic Battery we had purchased from Pegasus Racing.  Even though the tech guys at Pegasus had assured us that this battery could easily start and run the big 8 liter Chevy engine in one of our race cars, when we hefted it's 6.5 lbs, we knew that there was no way it could!

An Inside Look at mountune's GRC Ford Duratec Engine!

by Mike Kojima

The current engines used in today's GRC Rallycross racers are some of the highest stressed production based engines in all of Motorsports.  Only Import Drag Racing engines see more stress and perhaps no production based race engines not even Time Attack engines are stressed for as long a period of time as Rallycross powerplants.

Breathing through a 45mm restrictor that limits power to "around" 550 hp, the mountune Ford Duratec puts out 625 lb/ft of torque.  Because of the restrictor, the Garrett Turbo pumps in 45 plus psi absolute of boost to make that power, generating an amazing 3200 psi of cylinder pressure.  To put this in perspective, this is more cylinder pressure than the Audi LMP1 Diesel!

The CSF Radiator Challenge!  CSF vs Masiv

by Mike Kojima and Khiem Dinh

During the summer CSF radiator launched a bold ad campaign with MotoIQ: the CSF Summer Challenge.  CSF boldly challenged the entire radiator industry to s shootout to see who makes the most effective radiator with us conducting the test.  CSF's only rule was that a radiator for the challenge had to be an off the shelf part built for a given car available to the general public, not a one off bespoke radiator designed just for the test.

The Fabulous Flog: A Look Inside Dai Yoshihara's Falken Tire Subaru BRZ

by Mike Kojima

What is the Flog?  It is the nickname that the Falken team has given their BRZ drift car.  Driver Dai Yoshihara, commented when he first saw the completed car that it looked like a frog but with his Japanese accent it came out Flog and no one knew what he was talking about.  Dai had to pantomime a sitting frog and say riibit, riibit before anyone could understand that he meant Frog. 

The Falken Tire Subaru BRZ has been featured by a few other media outlets in the recent past but not like this.  Let us take you beyond the pretty pictures for a look inside the car which has been one of the most anticipated builds of a drift car to date.   One of the best looking cars on the Formula Drift circuit, the BRZ was built on a compressed time schedule by SPD Motorsports, the same folks who built Dai's iconic Discount Tire/Falken Nissan S13.

Project SEMA Scion Tuner Challenge FR-S, Getting More Power with a Ganador Exhaust

by Mike Kojima

Our first step in extracting more power from our FR-S's FA20 motor was to add an Unorthodox racing crank pulley which went pretty well.  Now we are going to take another baby step along the path of bolt on modifications by testing out a Ganador Exhaust system from Japan.

Project White 5.0 Liter Mustang - Getting More Easy Power with an AEM Intake!

by Mike Kojima

Our Project Mustang has been doing just fine with its new suspension and tires which have drastically improved the car's handling.  With the chassis doing a lot better and with the car's factory Brembo brakes adequate for now, we decided to do the classic Mustang thing and tackle the engine.  Our first step will be the addition of an AEM air intake.

Project SEMA Scion Tuner Challenge FR-S: Easy Power with an Unorthodox Racing Pulley

by Mike Kojima

In previous installments of Project SEMA Scion Tuner Challenge FR-S, we've worked on improving the suspension, braking and improved the grip with a new set of wheels and tires.  Now we will start focusing on getting more power out of the engine.  We will begin with simple modifications and start to ramp things up in our quest for power.

Our first step is perhaps the most basic, adding a lightweight Unorthodox Racing front pulley. The Unorthodox pulley is not an underdrive pulley but a lightweight pulley that takes several pounds off the engine's reciprocating mass. Spinning up extra mass takes power and a lightweight pulley can free up some of that power to reach the rear wheels.

Project M3: Part 8 - Dealing With The Dreaded EML Light

by Pablo Mazlumian

If you've ever had the yellow EML light come on, it usually has to do with the drive-by-wire system.  In Project E46 M3's case, every time it came on, it would stall the car and render it useless unless you knew what to do to reset it.  Check out what we did to get the car running tip-top again.

Nerd-O-Scope: Keeping the Energy In Turbos Using PTP Turbo Blankets

by Khiem Dinh

Photos and Graphs Taken from “Performance Improvements of Turbocharged Engines with the Use of a PTP Turbo Blanket” by Steffen Bickle, Ronald D. Matthews, The U. of Texas at Austin

Everyone who has been reading MotoIQ has heard me say it time and again, heat = energy. Why is this especially important with turbos? Because the turbine wheel in the turbo takes energy out of the exhaust flow to spin up the compressor. The more energy available for the turbine to grab means there is more energy to spin up the compressor. Here is the proof.

It's All About the Zinc - High Stress Wear Resistance with Penrite Oil!

by Mike Kojima

We get a lot of oils and lubricants to evaluate at the MotoIQ office and for the most part we have had good results with the latest high quality synthetic motorsports oils that come across our desks and into the crankcases of our various race and project cars.  When it comes to quality oils we get pretty uniform results, clean burning, low deposits and good wear of the engine's internal components.
