Wiseco Forged Pistons


Wiseco Sport Compact Forged Pistons

Our Sport Compact pistons are made from dedicated forgings produced in-house to give you a light weight piston with superior strength and optimal design. Being the multivalve piston technology leader, the line features specially designed valve pockets, complex dome and crown shapes, the steel nitride/napier xx rings and optimized skirt profiles. The pistons come standard with our ArmorGlide® coating material for reduced friction and noise, freeing up horsepower.

Piston Engineering / ArmorGlide™ Coating

Wiseco’s detailed skirt shapes and profiles are very specific to each application. Variable cam programming software developed in house allows Wiseco to produce high-performance shapes unique to only Wiseco. The skirt shape (barrel/cam) is one of the most functional areas on the piston, and provides stability and smooth operation in the cylinder bore. Stability is important for proper ring seal, reduced friction, and quiet operation. Each skirt shape is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy. Some forging alloys expand more than casting alloys, but each Wiseco piston is designed with the proper installed clearance to produce the most power, least wear, and best seal at running temperature, for each application. Comparing installed clearances on cast vs forged parts is not indicative of the running clearance at temperature. Wiseco engineers have a strong background in all forms of racing applications, and produce the best shapes and designs in the industry.

Some of our forged pistons offer our new ArmorGlide™ skirt coating, which is the result of testing, development, and benchmarking through Wiseco’s rigorous in-house dyno program. The outcome is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance. Not only is ArmorGlide™ a high-tech lubricant that reduces friction, but it also allows the piston to be fitted tighter within the bore allowing a better ring seal and reduced noise from piston rock.





Wiseco Forged Pistons price is almost identical to CP Pistons price but somehow Wiseco gives you a feeling of quality and precision over their products after going through their website and their product lineup. It just feels like you're getting a bigger bang for your buck so I would highly recommend Wiseco for those who want a cheaper option than HKS, Tomei or etc. For more info go to http://www.wiseco.com/Catalogs/Automobile.aspx

Little Updates on my car. Just gotten a used Trust Oil Cooler Kit. Its just been installed behind the intercooler.
If you look properly, you can see the Trust word engraved but I guess Blogger lowers the quality of the pictures a lot so some of you might not see it


Finally my mech changed the driver side headlamp motor and the headlamp now is able to open again. No more One eye blind! The thing that caused the old motor to malfunction is because of a simple thing, guess what? The plastic cover. It didn't have one so sometimes when it rains heavily and the water splashes and on it goes into the motor. I can confirm that because my mech told me that when he took out the old one, all the water came splashing out. LOL

It's Down, Polished and Everything Nice


Has been a long time since my last post because I have been pretty busy with work and my car as well. So far the modifications has just started. My 1994 SR20DET Blacktop is being rebuilt at the moment with some goodies going in of course. Well this in kinds a big project for me as everything from the head till the tail is almost all changed to make this car a reliable and a mean piece of machinery.


Engine's out!!!


Engine Head That's Fresh From Skimming and Polishing

Stock Pistons

If you look carefully at the top of the piston on the right, it is actually damaged caused by detonation in the engine therefore you can see some of its metal has chipped off and it left a black burn mark.

Crankshaft

Polished Valves

Valve Springs and etc

On Monday, I received a call from me friend Jerome(S15 owner) at midnight saying that he found a Nismo Super Coppermix Single Clutch that he thought it was for the S15 6 Speed and but after consultation by his mechanic, it is actually for the S13 and S14 5 Speed. So he offered to me whether if I would wanna buy it for a very very good price. After close inspection by my mechanic, he said that the Coppermix Disc is still quite thick and for the price, it is very worth it as it is indeed a rare item. So without hesitating, I bought it. Enjoy this rare piece of Beauty in RED!




After much thoughts, I decided that might as well change the worn pistons into forged ones since the engine is disassembled. So i got this!

Wiseco Forged Coated Pistons

It is 87mm bore which literally strokes the engine up a little bit from 1998cc to 2045cc. So basically my engine's gonna be a SR20.5DET when its done hahaha

Till the next update. Have a nice weekend ahead guys!
