Added Window Spoilers to the Volvo S80, I like the look but also they lower the wind noise when driving with open windows.
Also if it rains, you are still able to drive around with open windows, without any water ingress. And in the hot summers, you can safely let your windows down a little to stop the heat from building up in the car.
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
I had pretty big plans for the S80, shooting for a 270bhp instead of the 200bhp that the 2.4T has normally. You need an upgrade turbo for this, which I sourced from a T5 model, which has 250bhp bone stock. The swap would involve the TD04HL-13T to TD04HL-16T or 13T to 16T for short.
Fitment is pretty straightforward, but the coolant lines run differently, and this was quite a hassle as information on the internet seems very scarce. I found some, but needed some creativity as the build progressed.
I was also planning to mount the later “R” series manifold, but decided to sell it, as the Japanifold would give much better sound and equal performance.
In the end, I sold the 16T and mounted the 13T, saving the money up for something else. I needed to adjust the car a little bit, and according to the max MAF values, it makes about 240-245bhp, which is awesome.
It’s a totally different car from when I first bought it, that’s for sure!

Rubbing will occur here
When you have an older car, always think about replacing the engine mounts. They are almost always made of rubber, which becomes brittle over time due to aging/drying out.
I replaced all the engine mounts, which tightens up handling and improves performance and reduces strain on components like the exhaust, as the engine swivels way less. Highly recommended!
The old OEM armrest with the phone which I replaced for a new one (without the phone).
It was replaced with a new cream colored vinyl armrest from Aliexpress. Looks like new!
Added 2 diffusers to the rear bumper of the S80. Looks very nice and makes the S80 less of a Old Man car haha 🙂
Repaired / cleaned the PCV circuit as I saw a lot of oil in the pressure circuit (also see my previous post: https://www.ducked.nl/blog-entries/volvo-s80-2-4t-dirty-clean-turbo-coldside/ ).
Did a little research and the PCV system is almost always the culprit for such issues.
Decided to buy a complete system although ended up cleaning the existing system and only replacing the oil seperator. The tubing was quite some work, I will save that for another time.
