Hello everyone

here is my engine preparation 2.1 td 12 v
- reshaped camshaft + mechanical pusher passage
- turbo gtb2565vk (in preparation at turbo-upgrad)
-pump diesel injection prepared dieselmeken 12 mm 300 a 320 hp
forged big section
-balanced balance (aluminum dumper + lightened engine vollant 4 .6 kilo
-kit water / methanol
-disque 4 pation mechanism reinforced sachs

- ARP rod and cylinder head
- evans coolant 
the ratio of xud 2.1 td is 21.5 / 1
does the power of more than 300 hp need to lower the volumetric ratio to 20/1 or 19/1?
