Hey guys! :)

I've have tried to search around the web to find answer to my question, but haven't had much luck, so I hope this forum can help me.

I'm currently running stage 3 on my Ibiza cupra with IHI IS38 and supporting mods such as HJS 200 cells downpipe with milltek non-res catback, HG motorsport carbon intake, wagner competetion intercooler etc.
So my question is, if I upgrade the HPFP and LPFP and get a LM440 IS38, would the car drive vastly different? I don't wanna lose the daily driveability, but the car has driven 350.000 km now and over 200.000 km have been with stage 3 and 360 HP, so it's beginning to feel a bit slow and i wanna push it a bit more

Does anyone on this forum drive an Ibiza cupra with an LM440 turbo?

Yes with the HPFP alone and with the Golf R oem IHI IS38 you should easily achieve between 380-400BHP. With the LM440 IS38 and HPFP in the mix you will easily achieve upwards of 460BHP with the right tune if that's how far you wanted to push it (engine failure is highly likely above 450bhp). I don't think the LPFP is necessary unless you're planning on running meth/E85. Again this will all depend on your tune and the health of your engine as you wouldn't want to be pushing a 350,000km engine to the limits without knowing it is 100% healthy. I have driven in a 470bhp Ibiza Cupra 1.8 before and they are insane haha.

As above, just the mk7R HPFP is needed to run the LM440... But, no harm in replacing the LPFP as that is also already 350K old... Better to have it fresh and capable of flowing the fuel, then to ruin your engine due to fuel starvation because the LPFP couldn't keep up the demand...

He's completely right as the lpfp is only really designed to last between 100,000 - 200,000 miles. Although any fueling issues you might run into will always be uncovered based on how the car responds when mapping so it isn't a bad idea to run this by your tuner and get their input.
