Volvo S80 2.4T Japanifold Exhaust Manifold

When I wanted to mount the TD04HL-16T turbo, I also wanted to couple it with the Japanifold, that should give good performance, but also the distinctive rumble of the 5 cilinder engine. I scored one via internet for a good price. The quality is immaculate, as they can handle a lot of abuse before they even start cracking.

But in the end I sold it, because my 2.4T already had the Japanifold fitted, so happy days 🙂 !

They are made in Japan, hence the name “Japanifold”. Partnr: 9207688

Volvo S80 2.4T ProPerfekt CBV / Diverter / Blowoff Valve

I actually wasn’t planning to upgrade the OEM Compressor Bypass Valve (CBV), but I am glad I decided to do so with this ProPerfekt piston type Diverter Valve (DV).

The rubber rings don’t leak (so much) boost, which means the power output is better (and faster) compared to the stock CBV. The stock CBV has a rubber outer ring (diaphragm) and a plastic ring on the inside (this is the flaw in the design).

The ProPerfekt DV is a known mod with the Renault Megane RS drivers, but I haven’t seen it before on another Volvo forum. The results are clear to me, the boost buildup is quicker, which means the car is faster. I would recommend this mod to anyone who has a TD04 turbo (who is still using the stock CBV). My S80 has the TD04HL-13T turbo, but will also fit the TD04HL-16T. Please note that the CBV I had fitted is quite new, so no ruptured diaphragm or something.
