Most Popular Questions

Is this a bolt on product?
View Staff Answer 
The turbo bolts directly up to the ALH and uses the same oil feed and return lines, but it requires an adapter for the compressor output to match up with the stock ALH intercooler pipes.
Will this fit on a 2000 VW Golf 1.9l TDI?
View Staff Answer 

The Garrett GT1749V Stage 1 Turbo Upgrade 721021-5006S will fit any of the ALH engines. You'll find the engine code on a sticker attached to the timing belt cover.
