Looking to buy the s63tu eu5 injectors and swap them into my 2014 335i pure stage 2 turbo on tuned to e50 that's making around 530whp. Its currently on the stock eu6 injectors and those keep failing on me. Will s63tu eu5 injectors fit into the n55? Do i need to code them? Do i need to get a new tune? Are they rated for more than 550whp on e85? A lot of questions lol. If you have any information on them let me know!

Note: I've tried looking for information on other forums but had no luck!

You need to talk to a tuner as you will need more than coding.

Better off looking into the nostrum injectors

Install and code to dme is the same as replacing stock ones. Norstum stage 1 injectors are the same as those.

You'll need an upgraded LPFP + HPFP for this injectors. Need a custom tune. Just coding them to the dme isnt enough. Appears you'll need a stage 3 HPFP upgrade or the overdrive HPFP offerings.

On n55 it appears s63tu injectors are limited to 700 whp for full e85. The bottle necks will be your HPFP and LPFP

You'll want to see this thread.

I guess I should have said the nostrum stg2 injectors.. not the stg1s. But yeah, hpfp and lpfp are obvious..

Ah. I had no idea the stage 2s were out. 1600 for stage 2 injectors though. Yikes !

Im currently the fx-180 HPFP and Spool Performance S2 LPFP so i should be good with s63tu injectors right? Plus do you have a part number or link where i can buy the s63tu injectors? Dont wanna purchase the wrong ones ))))
