Seems like my friend Tupac already made my introduction
My 1.9JTD 16V had a turbo-upgrade one month ago. As my stock turbocarger was taking its last breaths, I decides to think BIG
, so I changed my VNT 18 stock turbo with a hibrid one: VNT 20 with a 22 compressor. Still Garrett, still bolt on, I didn't have to do any mods to it as it fits perfectly. The results are impresive, the car has transformed into mean lean road-eating machine.
The problem with a bigger turbo is of course turbo lag. Because your new, bigger compressor unit has to work with the same amount of exhaust gass, it will begin spinning at a higher RPM. BUT if you have a skilled tuner who can program your ECU, you should be fine. Currently my tubo kicks in at about 2000rpm and hits maximum boost at about 2600rpms. With this mild soft I work with 1,2 bar in boost, in a few weeks time I should reach 1,5-1,6.
I recomend this upgrade to all my JTD brothers, over the years I've had the novitec power-box, an agresive remap and now this turbo-upgrade. The future looks bright
