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.
Thinking about going racing this weekend? Karla Pestotnik and Rob Choo use the GTChannel S2000 to show you step-by-step how to change your differential oil, motor oil and transmission oil, as well as how to bleed your brakes and clutch fluid.
In Part 1 of Size Matters, we went over the basic concept of sizing the turbo for the application and desired torque curve shape to match the intended use of the vehicle. You know, because a couple million people a year ask what size turbo they should get for their _______ (insert application here, i.e. car, motorcycle, boat, scooter, lawn mower, etc). Once everyone gets a bit more turbo savvy, they learn of the concept of boost from a small turbo does not equal boost of a big turbo. Well, we’re going to explain why.
We decided to be different and tackle the Subaru WRX as our latest Project Car because it's big sister, the STI has been always getting all the attention. More people can afford the WRX which we consider to be a performance bargain and more enthusiasts drive them. We will be working with ARK Design to get this car going and make it more fun to drive.
One of the first things we did as is typical on most of our project cars is to work on the suspension first. Since we are still deciding on what to do for dampers on our project, we decided to start with changing the soft rubber suspension bushings with some polyurethane parts by Superpro.
If you have been following Project Tundra, you know we have been struggling with excessive activation of our truck's stability and traction control systems. The improved power of our supercharged engine and additional traction of our larger tires have been driving the electronic nannys of the truck's OEM systems crazy. We were hopeful that a new adjustable rear antisway bar from Hellwig would help.
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.
One of my tasks for this winter was to ensure that all of the vacuum lines on the SR20DET were accurately connected. Small stuff but I have not been positive that it was completed properly. I have put off an accurate setup for too long. While I read tons about this on SR20-forum, I went to my buddy Will at PZ Tuning for the expert's touch. After all, if you miss the small stuff it may damage your car.
Take a look as we enhance our E46 M3's appearance with a new carbon fiber splitter, carbon fiber rear diffuser, and a plethora of underside neon lights! (think about what day it is before you flame us).
The guys at Motovicity have been singing the praises of HKS's new Max IV coilover systems to us for a while. While we have generally always been impressed with HKS's tidy OEM like engineering, it was a while since we had experienced their coilovers. In the early 2000's we had tried some of the original Hipermax suspensions on a few of our cars and although we found them to be of high quality and smooth riding, they did not have enough spring rate and damping for serious performance with big sticky tires and especially track use. We sort of regulated the brand as nice for street use only and looked toward other places for suspension for our projects.
Fast forward 10 years and 4 generations of Hipermax suspension later, plus Motovicity's raving about them made us eager to get our hands on the Hipermax or Max 4 suspension system for another review.
Our government connection West Virginia Legislator Delegate Gary Howell sent us these pictures today. Apparently Gary was eating at a Chick-Fil-A and noticed that a disguised vehicle was sitting in the parking lot. He managed to snap a few pictures before the car's driver sped off in it. If you look close you can see his reflection in the glass! We think that the heavily disguised vehicle is the new 2016 Camaro. In fact, we're just about sure it is.

With winter finally departing, for most of us car guys, that means racing season is back! F1 and Moto GP will soon get back on track and local time-attack and racing series kick-off their season as well.
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.
We test out Auto Meter’s incredibly advanced Elite gauges and examine the technology that makes some gauges better than others.
