Hi guys, after some advice.

Ive got an E92 335D with MTC Downpipe and intercooler, back box delete and stage 2 map, currently running ~365bhp.

Ive just ordered a pair of hybrid turbos, but unfortunately due to Corona, my business is on hold so cant do any more. Does anyone know the power potential with these mods but no R90 HPFP? The hybrid turbo will have a 76mm compressor wheel with a newer turbine with clipped blades.

Ive had wildly varying estimates from 450bhp on stock pump to not being able to get over 400bhp without an R90. Does anyone have any experience with this or know of any examples?

Cheers guys!

Ive actually changed the build now, speaking to a tuner who has worked on a 500bhp+ 335D, he said an R90 with stock turbos can produce 400bhp+ as they can provide much more fuel. The fuel pumps are a fraction of the cost, I picked one up for £160, compared with ~£1000 for hybrids.

Im going to couple that with a meth injection kit, hes hoping to get about 420-430bhp out of it. I then might look at hybrids.

You found an R90 pump for that cheap? Can you find another? Guys over here selling them for 10 times the price.

Yup!

So the thing is, tuning companies charge like £500 for an R90 because they know there is a demand, but a few older cars have them as standard, such as a 2006 - 525D. So I just went on Ebay and found one from a 525D that was being broken. Cars to look for are: e46 330d.. Or 530d 525d pre lci e60 for example. Or search for M57N High pressure fuel pump. Dont search specifically for an R90.

There were a few on Ebay, heres some one Europe for about $220

Wow this is gold info. It’s direct plug and play like the actual one tuners sell?
