1.8 20v Turbo

Well, it would be silly not to include some information on this site for the 1.8T conversion. So, we shall be adding as much information as we can find to this site to that effect. There are many ways that this can be achieved, from plug and play looms/kits available from a some suppliers through to using a full late loom, engine and dash from the donor.

One of my mate bought the 'Plug and Play' loom, ECU and downpipe from QPeng and had a Seat Cupra 1.8T in and running within a weekend. Talk about a simple conversion! He said the only problem he had was traction! lol

Anyway, watch this space....

Why a DOHC 16 Valve Turbo

It is clear that many of our friends over the pond are very keen to turbocharge their 16v Volkswagens. There seems to be a different school of thought on this side of the pond and the 1.8T Conversion seems to be more desirable in the dub 'scene'. This is however, not necessarily the better option. Maybe it's because the 1.8 20v turbo engine is already force enduced and makes it an easier installation, and therefore is already built for that purpose, but the 16v turbo has so much more capability. If the Americans build a lot of them, maybe they have the right idea?

Big power can be achieved from the lowly 16v, and it has some characteristics that lend itself to the conversion. Firstly the head can flow a very large amount of air, but it's is debatable to whether this is more that the 20v head. Volkswagen opted for the 20v as the third inlet valve improved cylinder filling off boost, but the valves aren't anywhere near s strong as the 16v valves, so it's common to see 20v engines with dropped valves. Furthermore, the 20v has some issues with the block, and it wasn't until the later engines found in TT's (engine code BAM) that they redesigned the block.
