16V and Silvertop engines all use a rubber dampener in between the middle Section of the primary crank pulley and both equally of two outer pulley rows. The Blacktop on the other hand only has dampening over the pulley row that is over the aspect closer into the engine, as a result the outwards facing row around the pulley that is the one which likely drives the power steering pump in addition to a/C compressor will not be dampened.
To allow for the real difference in cam belt tensioners the oil pump castings are different amongst the engines. They are interchangeable if all another belt tensioning sections and cam belt are altered simultaneously.
– Conversion notes: The spung tensioning method is often swapped on to a Blacktop but Furthermore, it calls for the swap of various other elements. In overall the parts necessary from the Silvertop would be the oil pump, cam belt, cam belt stress pulley, tensioning spring, the steel write-up fitted into the block for your spring to loop above and lastly that The underside and Center plastic belt addresses possibly be tailored or changed to that as employed with a Silvertop.
This engine was the first during the sequence to work with Toyota's twin camshaft method often known as Superior-Mecha Twin Cam, where by the timing belt drives the exhaust camshaft and also the exhaust camshaft then drives the inlet camshaft by way of scissor gears.[eighteen][19][20] The inlet camshaft acts as a slave camshaft on the exhaust camshaft (the latter acting as being a learn camshaft for that engine), which led for the system remaining unofficially generally known as the "slave-cam program".
The Obviously aspirated engine’s opportunity continues to be identified at 280 horsepower at 12,000 RPMs, but including pressured induction raises the bar appreciably, combining that top rev capacity with alternatively considerable quantities of boost could be the formulation for massive amounts of energy.
Your stock of Japanese motors is certainly the most effective I’ve Employed in a long time, and I’ve been working on Establish and swaps for just a little around a decade.
Yamaha designed the engine for overall performance; the valve angle was a relatively wide fifty levels, which at enough time was thought to get ideal for large electrical power manufacturing.[25] Today, many modern superior-revving engines have lessened the valve angle to twenty to 25 degrees, allowing for a far more more compact and compact cylinder head and is also now believed to generally read more be perfect for large-revving engines with higher specific ability outputs.
The still left flywheel pictured is the earlier Silvertop design while the right is the lightened Blacktop.

Respiratory has to be optimized with impartial throttle bodies, and larger valves and valve seating.
The Silvertop Velocity stacks / trumpets are shaped from a hard plastic whilst the Blacktop utilizes a firm rubber instead for his or her development.
There's extremely minimal head preparing wanted, Except for match porting and sharpening the runners. Porting the heads on this 16 valve Twin Cam more normally decreases the air velocity- leading to poorer throttle response.
So this minor 11,000 rpm Starlet is in the same ability-to-pounds ratio class from the GTR. The only real variance could it be’s a hell of a great deal lighter and being significant RPM NA, it possesses unparalleled response levels.
The flexibility in the 4AGE engine is one of its most appealing features. It's been fitted into a variety of motor vehicles, showcasing its adaptability throughout various platforms. Here’s a evaluate many of the most notable purposes:
