I have a 2002 Jetta TDI and was thinking of adding a second turbo. What other upgrades should I make before so my engine can handle the extra boost?
what would you recommend to upgrade?You don't want/need that. With just one turbo, and a few thousand dollars, you can easily build an engine that will overwhelm the chassis, the clutch, the transmission, and make it a chore to drive. If you just want to make more power, a dual (parallel or series) turbo setup would be so far down the list that I'd not even bother thinking about it.
That would depend on your budget and your goals. How much power are you looking for?what would you recommend to upgrade?
So many threads here on just this topic. Literally the next one down is basically the same. Bigger nozzles, bigger turbo, bigger fuel pump, bigger exhaust diameter, and a tune, and you will make a little 1.9 liter beast that will try to escape your engine bay. Not necessarily in that order, but do all that and you will turn your clutch into a puddle. Then do a clutch and you will be able to spin the tires in second with just the accelerator. Not a very technical description of power, but still. But just a note of caution, it's a slippery slope once you start.what would you recommend to upgrade?
