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.


Turbo Tech: Size Matters! - Part 2

by Khiem Dinh

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.

Building the Ultimate Turbo Small Block Chevy Part 2, The Making of 1100 Hp!

by Mike Kojima

When deciding the best way to power Daren McNamara's Formula D S14, Team Falken decided to plow into new territory with not just a turbo, but a turbo V8.  Not your typical Chevy LS V8 either, but a blast from the past old school Small Block Chevy.  In our last edition of building the ultimate Small Bock Chevy, we looked into the developments that had been made to the venerable 60 year old design to update it to modern standards, particularly the bottom end. In short, the improvements were mostly moving the cam upward to allow for more stroke and to shorten the pushrods for less flex, and a general beefing up of the lower end architecture to support today's power levels.


 

Building the Ultimate Turbo Small Block Chevy-Part 1

by Mike Kojima

The Small Block Chevy is a dead outdated hunk of iron that is best left to old guys puttering around restoring muscle cars in their garages, or is it?

The venerable Small Block Chevy was first introduced to the motoring public in 1954 and was installed on the assembly line until 2003 and is still in production as a replacement motor.  This means that the good old small block has been around for 60 years, making it one of the longest lived and most produced engines of all time with over 100,000,000 being built to date.

Dai's super small block is in the process of being built for even greater power and reliability in 2016 but it's worth a look back to see the state of tune just a couple of years ago.


 

Project Toyota Supra MKIV: Part 6 - 800whp build update!

by Pablo Mazlumian

With all the parts needed to move forward, Project Supra is now on pace to get fired up!  Not only are previously featured parts installed, but we continue to add new stuff as well.


 

Project Supra (Extreme Engine Tech): Part 3 - The Cylinder Head

By Pablo Mazlumian

We're taking our 800whp Supra build a step further with a fully built cylinder head, including Titan cams, Ferrea valvetrain, and port matching the head to the Hypertune intake manifold.

 

EXTREME ENGINE TECH: 2JZ-GTE Engine Build; Part 2 - Modified Oil Pump and Crank Damping

by Pablo Mazlumian

While we await our cool turbo components, we tackle the oil pump and crank damper after recently discovering that our previous motor could have seized catastrophically!


 

Extreme Engine Tech: 2JZ-GTE; Part 1 - More Strength, Less Weight

By Pablo Mazlumian

Known as one of the badest blocks that ever left an assembly line, the 2JZ-GTE found in the MKIV Supra is known for its ability to handle horsepower. Unable to contain ourselves, we build one, and make it even stronger.  We start by discussing our piston and rod selection.  The goal? A streetable 800 whp, daily-driven!


 

Rotary madness, motoiq

Rotary Radness, Mazdatrix's 13B REW/MSP Hybrid!

By Mike Kojima

So far we have not focused too much attention on the Mazda Rotary engine on the pages of MotoIQ.  This is not because we haven't wanted to but because no one on our staff has much expertise on the engine except for Eric and he has been pretty busy lately doing other things in the world of internal combustion besides messing on rotaries.
