B48B20A 260/420
B48B20B 310/470
B48B20D GPF 220/370 tai ~300/370 vääntöjä rajattu , ettei ongelmia tulisi
jos oikein ymmärtänyt niin alkupaan koneista osa ollut tuolla B20B koneella eli 330i koneella, niin on saanut hyvin lisävoimaa ohjelmalla.
Nimeltämainitsemattoman Suomi pajan vinkistä tätä GPF versiota on riski yleensäkkin ohjelmoida. Ja mietin tässä, kestääkö edes noita jo rajattuja vääntöjä 370nm?
lisätietoa / kokemusta asiasta arvostaisin.
Realoem näytti VIN koodilla B48D eli kaipa sitten se versio...B48B20D

Bimmercat:
"there seem to be two variants of the 320i. Bimmercat calls them B48C and B48D. B48C appears to have the B48B20A engine"
"B48D, however, appears to feature the B48B20B engine"
By comparing 320iX (B48C) and 330i (B48D) on RealOEM I found differences:
- engine block
- different turbo
- intake manifold system
The rest like heat management, cooling system, lubrication system, timing chain, belt drive etc. seems to be exactly the same.
I guess the biggest difference is the turbo boost pressure. From these pictures it looks like the biggest difference is not the turbo size but the outlet pipe diameter. The one in 330i has 4 separate chambers while one in 320i has 2 parallel ones. The diameter of these pipes are much bigger in 330i allowing for higher air flow and pressure.
So 320i (B48C) is not just de-tuned 330i (B48D). But 320i (not xDrive) manufactured before June 2019 had engine B48D (I tested one) with the same turbo as 330i today and that's why it looks like only de-tuned.
......
I don't think automobile-catalog is 99% accurate.
I found this analogy:
B48B20A = B48C (320iX and since 06/2019 320i)
B48B20B = B48D (320i until 06/2019, 330i and 330iX in EU)
B46B20B = B46B (330i and 330iX in NA and until 09/2018 also in EU)
I trust realoem and bimmercat more.
