Product Description
We are extremely proud to announce our final step in offering the normal DIY/Garage Built Honda J-Series Enthusiast the ability to build their own 400-800hp J-Series motor from home. The final piece to this puzzle is our brand new HalferLand Performance 800hp J32/J35 89mm Hypereutectic Pistons. We spent many days and nights developing our pistons and coming to the final design you see now. We wanted to offer a robust, sturdy piston, but also one that would not break the bank and still allow our customer to achieve there horsepower goals and stay within their budget....AND WE DID IT!
 Hypereutectic pistons (High Silicone Content and Heat Treated for added resiliency) are not new to this industry, with the majority of the large automotive manufacturers utilizing "hyper" pistons on their factory forced induction vehicles.  Here is a brief link if you want to read up more on the material and piston.
"Hyper" pistons are capable of withstanding the higher heat and loads caused from forced induction and Nitrous, along with great resiliency to heat soak which can lead to detonation and ultimate engine damage. To add another layer of protection all of our HalferLand Pistons will come standard with an Anodized Dome to withstand higher cylinder temps, while also hardening the dome for greater cylinder pressures. Along with the anodized dome our pistons will also come standard with the anodized top piston ring land grove, to help with preventing piston ring sticking and also helping keep all oil drain ports clear from clogging. Lastly, our pistons also come standard with our Moly "Glide" Side Skirt Treatment (Not Standard Moly treatment, our "Glide" treatment is a hybrid ceramic and moly treatment which promotes greater lifespan) to ensure smooth operation for the pistons within the cylinders.
Our "Hyper" Pistons will come in the standard 89mm bore (Standard J32/J35 Bore) so no over boring of your cylinders required as other Over Bore/ Oversized aftermarket pistons (You can still safely re-hone the cylinders if needed). The pistons are also based off the Honda J35a3-a4 pistons, bringing the compression to a safe Boost capable compression of 10:1 for J35 engines and 9:1 for J32 engines (Head milling can be performed to fine tune compression if needed. We will come out with other compression ratio pistons down the road). 

Some Confusion
HERE is a GREAT video that will help explain the benefits of our Pistons over normal cast aluminum alloy and even forged pistons!
We wanted to address some confusion and concerns. As always, there are some characters that are spreading the word our pistons are simply stock aftermarket pistons with a logo added to it.  So to address this, we wanted to address some outright difference between our pistons and stock aftermarket pistons. 
Many with no knowledge of molding or manufacturing will point out similar looks between the pistons....YES, they after all are J-Series pistons, with the same bore and specs....not sure how different they should look. Why do they look similar?? Well Instead of producing a $15,000 brand new mold, to save money for our customers we opted to use our partner factories J35 STDmSTD which happened to be the exact specs we wanted (10:1 compression on J35's). Outside of using the same mold, that's where all similarities end with our pistons to stock cast pistons. Our Pistons are not made of the standard Aluminum alloy that stock aftermarket cast pistons are made of, but instead we implemented the use of Hypereutectic alloy which is much better at withstand heat and absorbing higher loads. To add another layer of protection we also added our anodized dome and top ring land. Both of which add additional strength and heat dissipating properties. Lastly, we took it one step further and decided to try our partners new Moly/Ceramic hybrid side skirt treatment, which no aftermarket pistons offers on the market.

These Piston are A1 quality. Went ahead and took the piston to wall clearance and they fell perfectly in spec , on the tighter side which I wanted to see so it can wear in. Highly recommend these to anyone.

Group Buy
Purchased on their group buy and man so glad I did. Quality is superb, everything they said it would be, fit perfectly like a glove and the motor spins over smooth. My 05' TL on 12psi 62mm Holest Turbo should be right around 400whp and is running perfect with the pistons in there. Thank you will be back for more parts

I was slightly hesitant to try these (just being honest) but have ran them for the last 4 months at 750whp in my Teggy swap J35a4 and they are performing flawlessly. Very impressed with the performance, look, fitment, everything. Best of all is the price!

These are a no brainier. Guaranteed to 800hp (I'm running at 650whp EK Hatch with no issues) and quality is amazing. Coming from a Automotive painting background, I can tell you the Anodized to the dome of the piston is very high quality.

Extremely Happy!!
I can honestly say you get what you pay for, but in this case you get WAY MORE!! I priced out forged pistons at over $1000-$1400, and after much research learned of the ill effects forged pistons could have on a daily driven high HP engine. I then found Halferlands pistons and after more research found many benefits to their "Hyper" pistons over forged (less wear on cylinders, better thermal expansion rates, comes standard with anodizing in multiple area's). Anyways. I've been runnng Halferland hyper pistons in my boosted TL (Dynoed 607whp at 18psi but run daily around 500ish) and have had ZERO ISSUES. I have even taken a bore scope to the cylinder to find the pistons looking almost brand new, with the Logo still present....that's quality folks at a great price!
