bigger turbo - 1997 vauxuall astra 1.7 tds

hi, what turbo upgrade could I use to replace the original turbo, also any other parts that will ad more power before an ecu remap, thanks Ash

if this is the isuzu engine, you likely do not remap, as it likely has a mechanical fuel pump.
Upgrading the turbo would not be a priority. You could turn up the boost on current turbo, but first modify the fuel pump (max fuel, grind boost pin, governor modification etc.)

assuming its the isuzu engine, here's 67 pages to read

Not sure you can or would want to tune the GM engines found in some 1.7td

I was going to buy them, but sold my Isuzu engine.
