Pēdējā laikā aktīvi tika vākta info par 1.8t dzinēju un popolārākajiem turbo.
Sakotnējā versija uzinstalēt turbīnu no saab vai volvo tika atmestas pār plecu,jo vienīgā daudz maz sakarīgā versija ir TD04 15T no Aero saab,bet tā nav nemaz īpaši viegi atrodama un par lietotu prasa ap 200eiro,šī turbīna ir derīga līdz 270-280zs
Šis tas ko esmu atradis...

To properly size a turbo, you need to have some idea on what your goals are and how much work you plan on doing. Do you want a fast spooling turbo? Do you want to change rods? ETC.

ATP ELIMINATOR TURBOS
These are modified GT turbos with a ko3/4 style housings. They are a great concept but the problem with these turbos is that the flange is a huge restriction on flow. Also the housing style doesnt flow well enough for a high hp turbo. The GT2X and GT28R will be fine using a upgraded manifold and have reasonable spool. The GTRS and GT71R have a rather large increase in lag and lower power output compared to the T25 manifold and housing. Also it sounds like its a cost savings but in the end, it cost close to the same a whole kit. If money is an issue, a T series kit would be a better option.

AEB HEAD and PORTED HEAD
With the increase in flow from a larger turbo, the head flow in and out will also make a significant increase. The best way to accomplish this is with a AEB (97-99.5 A4/passat) head. It uses a large port design which is considerably larger than the small port in all other US 1.8t models (see pic below). The large port head is larger on both the intake and exhaust size and continues on down the runners. However, the AEB head does not come with SAI and the head will need machined if you choose to keep it. All parts between the 2 heads are interchangeble. Meaning if you have a bare AEB head, you can swap cams, valves and everything else. Also if you have a VVT car, you can swap over the VVT tensioner or use a nonVVT tensioner and have VVT disabled. There is plenty of info on this swap in the 1.8t section on vwvortex.
If you choose, you can also porta small port head toAEB port size. This will increase flow but not as much as a true AEB head unless the runners are increase also. The runners on the AEB head are wider than the small ports and some welding is required to match the runner sizes.
PORT SIZE DIFFERENCE
No šī visa izriet,ka budžeta tūningam vispateicīgākais ir AEB 1.8T dzinējs,kas nāk (97-99.5 A4/passat) ,jo tam ir lielākie stock galvas porti un klaņiem ir 20mm virzuļa pirksts,kas ļauj sasniegt 370zs jaudu. Un kompresijas pakāpe 9.5:1,kas padara dzinēju atsaucīgāku uz maziem RPM
