Bought a Teflon (PTFE) intake spacer for the intake manifold from Thermatec. It will isolate the intake manifold from the warm engine, which will result in lower intake temperatures. The phenolic spacers are identical in function, only the material used is different.
Lowering the Intake Air Temperature (IAT), will result in higher power figures. A simple supporting mod, which is quite inexpensive.
Pro tip: make a small indentation in the top left corner of the spacer where the bolt would go through the spacer/gasket (where the thermostat housing is), this will make the installation a lot easier due to the restricted space in that area.
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
To upgrade the performance on any turbo powered car, you need “breating” upgrades. The car needs to inhale better (intake modifications), but also exhale better (exhaust modifications).
The most important component in the exhale process is the downpipe, the first pipe after the turbo. Upgrading this to a larger diameter, will allow for quicker turbo spool, which helps in scavenging but also in building boost.
As a pleasant side effect, the exhaust note will also be more throaty! The S80 has very limited options on paper, but I was able to buy and fit this with help from J&D Auto Onderdelen, who helped me tremendously in the pre-sales process (making sure that everything would fit). I can highly recommend them!
It’s a quite expensive upgrade, but well worth it.
It’s highly recommended to get some new nuts for securing the downpipe.
Old vs new, look into the differences in the diameter of the neck.
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!
