For years, the 2.7T has been one of the most tunable, capable engine platforms in any vehicle, but limited by turbo choices. The 2.7T is an extremely tightly packaged engine, unlike the 1.8T and others, a very engineered turbo is required to fit the tight confines of the engine compartment. K04's have been the turbo upgrade of choice simply due to availability and cost, however they are a relatively tame upgrade, offering up to about 150HP more than K03's are capable of. While this is a nice jump in power, its hardly enough to sustain the HP hungered maniac.
After years of engineering and testing, the Tial 605 and 770 turbo kits are finally available in a complete package. These are not kits that require headers or new manifolds, this is a bolt in kit for factory turbos, and actually a much easier installation than even K04's. Offering a safe capacity of up to more than double what K03 turbos can do (in 770R form), this turbo kit can easily be pushed to 600+ crank HP in the case of the S605, and more than 750+ crank HP in the 770R. As a bonus, due to the highly efficient dual ball bearing center section (in the case of the 770R) and custom Tial engineered compressor wheels in both, the turbos offer completely reasonable levels of lag, typically coming on hard boost by 3300rpm and 4000rpm respectively. As a side note, to reduce cost, the S605 turbos are journal bearing, the same as the OEM turbos.
These tial kits can be considered an "eliminator" style turbo kit, basically directly replacing the stock turbos. This means things like downpipes, headers (if you have them), etc all bolt up just like factory. Our in shop labor rate for this kit is actually less due to the simpler installation compared to K04 turbos.
034Motorsport has worked closely with Tial engineers on these kits so we have real world installing and tuning experience We even supply an "installation tips" document with the kit outlining some of the more discerning parts of the installation.
Kits are not in stock, but are built to order and will typically ship in 4-6 weeks after ordering. Fits all 2.7T vehicles.
Tial inlet pipe kits are now included with all Tial turbo kit orders.
