Porting and polishing

It has been said by many that the head design of the E15ET is flawed and unsatisfactory. Basically the E-series head is a poor design on account of its restrictive flow properties. So what do you do? Porting and polishing is a general term describing the process in which the engine’s cylinder head can be …

Camshaft

Alternative camshaft profiles are available for the E15ET through a number of channels. A standard E15ET cam can be reground to a point to alter valve lift and duration. For more extreme cam modifications a grind on a new unground cam billet can also be performed. Both of these above options can be dealt with …

Manifold – Exhaust

In the power game a custom-designed and tuned exhaust manifold  to facilitate smooth and unrestricted exhaust flow will clearly be beneficial. The standard E15ET exhaust manifold is a well know restrictive area and is always most often than not replaced when chasing big HP out of the E15ET engine. A common problem with the exhaust …

Exhaust System

A volatile fuel/air mixture can be a very useful thing.  But after you burn it down to carbon monoxide and a collection of other lesser gasses it becomes little more than a liability.  What do you do with this liability?  Get rid of it.  Fast. Such is the principle of a performance exhaust system. A …

Manifold – Inlet

Inlet Manifold A Japanese-spec E15ET inlet manifold is an easy bold-on modification for Australian-delivery E15ET’s. This manifold features longer runners and theoretically has marginally better flow properties over Australian E15ET manifolds. Noteworthy is the fact that the design of these manifolds is such that the installation of one on an E15ET will realign the orientation …
