What year is ALH TDI?
Volkswagen 1.9L ALH TDI Diesel While Volkswagen has produced many very good diesel engines over the years, the “ALH” engine used between 1998 and 2006 is regarded as one of the best. These engines were only used in cars, with 1.9 litres litres of displacement over 4 cylinders; direct injected and turbocharged.
How much power can a stock ALH handle?
200whp is about the limit of the ALH, also anything over 30psi like stated above and the head will tend to lift. Nothing a set of upgraded head bolts won’t fix however.
How many miles can you get out of a Jetta TDI?
