Hey Guys! I have seen a few people come on here and talk about modding their C300's and making 400whp or something crazy and unrealistic. I have been building the M274 on my 2016 C300 4matic Luxury for about 2 years now. All videos, pictures, modlist, etc. are posted on my tiktok page (PM me for tiktok). Essentially a basic build compared to everyone else who modded their C300, being intake, downpipes, spark plugs, coil packs, WMI, internals, and turbo upgrade. I will say the big difference between mine and a few others I've seen is the JE Heads and Pauter Rods, along with the upgraded bigger turbo as opposed to a hybrid turbo. My biggest issue I've ran into is my fuel pump. My tuner says he feels the turbo and block can handle more boost, fuel, and power/torque overall, yet were not getting the fuel we need from the HPFP. I was wondering if anybody had any idea where to find a HPFP upgrade for the M274, because I can only find the LPFP upgrade, which I already have just not installed. I was also hoping if any of the geniuses know if I could use the HPFP from the M133 or the M139, seeing as how the blocks are almost the same, and most of the specs are the same down to a tee compared to the M274. Obviously they have bigger stock turbos, and their hpfps are pushing more fuel to compensate more boost. I also can and will post dyno sheets, REAL progress, draggys, ETC. In terms of performance numbers, the HPFP limited the car to about 275 WHP (4Matic), the cars fastest 0-60 it ran was a low 3s, and on the street I have ran a 12.5 1/4th time, but I was spinning all 4 pretty hard through 1st and 2nd. If anybody knows if the M133/M139 HPFP or HPFP upgrades could fit on the M274, or know anywhere to get a custom HPFP, please let me know!
