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.

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.


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.

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.


 

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.


 

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.
