B48B20A tuning

Halmes · 02-12-2024, 03:59 AM

So i got this 330e and was wondering about tuning it. How much should i tune it withing safe limits. They promise 360bhp/540nm with stage 1 and never anyone have called about broken pistons. Ofc 98R ja 15k oil change helps.

How much have you tuned 20A motor and still working?

I have seen broken B48B20A engines (usually cracked piston heads) on this and other forums but always over 280-300hp of the ICE (so 388-408 total for the 330e), and sometimes in countries with bad gas or 91 gas. I think 360hp (252hp on the ICE) should be safe, but I would use 93 (98 ron) gas to be on the safer side. Most stage1 tunes I’ve seen for the A engine are around 240hp but those usually are for 91 (95ron) gas.
