Struggling with the decision between upgraded twins + inlets vs. top mount single (VM TM w/6465 1.0AR) for a daily driver 335xi that will never see a track or airstrip.
I think with either option, most FBO people will still likely need:
Fueling (stage 2 or stage 3 LPFP + PI or VTT HPFP)
Charge pipe (some FBO, including myself, haven't had issues with stock CP + DVs)
Labor is nearly identical, though you don't need to hassle with shipping your old turbos back w/Single
Upgraded twins
RB or Stage2 = $3000 + cores (hexon are a cheaper option)
TFT inlets = $1500 (includes CP)
BOV = $250
= $4750
I agree there are cheaper options (including MM inlets or VTT inlets) but the TFT seem like the most potential for power out of those 3 options. You could go with Hexon, or VTT Stage 1, but you're not saving much money and leaving lots of power on the table for a LOT of labor.
VM Top mount
$6400 + CP $250 (BMS using stock DVs)
= $6650
This is less than $2000 more (yes, $2000 isn't exactly chump change), this gap gets even smaller if you're comparing VTT 2+ or RB "super" turbos.
The advantages, that I can tell:
- Minimizes regret factor and allows easy swaps of bigger or smaller turbos
- Happier engine with less octane required
- You could return your car to stock without the hassle of needing new or used stock turbos
Seems to me, that for all the labor involved, and potentially being a longer lasting solution, $2000 really isn't all that much more to spend.
