Exhaust Manifold.

Ive rush readed that...but did notice a post regarding not upgrading nozzles..

Tbh, i honestly cant believe that not upgrading them is a good idea....the nozzles and turbo is nie on the most important two things of any DI derv motor, the stock ones a f*cking TINY.... who cares about 10 million bar injection, we dont need that much pressure, i can make mine clean on boost at 200hp with just 200bar injection and nozzles the size of hose pipes...

Yes you can make 200 hp on a stock hdi, but i bet to god it would make it easier with bigger nozzles / better turbo...id have thought the rail pressure / hp pumps would be raping making 200+ on stock parts...it just makes no sence to me....why try to tune a derv with such limited components just because it "can" work...to be it should be chronic nozzles, big vnt / compound setup, basic exhaust / inlet work and a chronic remap....sadly its always the latter which seems to be the issue..

Once aftermarket diesel management systems start getting more and more affordable, i think we will see a huge change in HDI tuning, as finally the TUNERS will be able to TUNE there diesel.....
