jassi Posted April 9, 2013 Report Share Posted April 9, 2013 (edited) Hi guys as some of you may know I'm breaking a 330d 204 bhp and am putting the drive train into my saloon before I place it in I want to do all the mods I require prior to a remap to get some serious power. On the list to do: Swirl flaps - blank them or simply remove them as some specialists are doing New dmf with a 5 paddle clutch Turbo - confused on this one between hybrid and roller bearing Fmic 535d injector nozzles - possibly mixed reviews Decat all the cats Edited April 30, 2013 by Daz 330 Cs Edited topic title due to typo Rob_ 1 Link to comment Share on other sites More sharing options...
Paul TVR Posted April 10, 2013 Report Share Posted April 10, 2013 How much power are you looking to end up with? Link to comment Share on other sites More sharing options...
jassi Posted April 10, 2013 Author Report Share Posted April 10, 2013 Just over 300bhp with loads of torque. Link to comment Share on other sites More sharing options...
e46rob Posted April 10, 2013 Report Share Posted April 10, 2013 I may be mistaken here, but I'm sure ive seen on here that you lose torque in the midrange (smack on where a good diesel is best) by removing all of the cats, hence why most just lose the rearmost one. Yeah, you'll get more bhp but as you surely know, peak figures aren't as relevant on the road as a good spread of power and torque throughout the rev range.

momo Posted April 10, 2013 Report Share Posted April 10, 2013 Swirl flaps - blank them or simply remove them as some specialists are doing - Blank them out New dmf with a 5 paddle clutch - I suspect you may need to go custom. I think even the Sachs racing clutch is rated up to a certain lb/ft level Turbo - confused on this one between hybrid and roller bearing - Not sure but i've found the biggest one you can find is always the best! Fmic - Allard or custom 535d injector nozzles - possibly mixed reviews - Not sure about the mixed reviews but these are the main limiting factor on the M57N. Upgrading these to get more power is a MUST. Decat all the cats - Yep! Speak to L33JSA and the exhaust he got. Sounds like that one is the best for performance.

jassi Posted April 10, 2013 Author Report Share Posted April 10, 2013 A couple of tunning companies are assuring that the injectors are not the limiting factor, but i have seen on BMWLand forum that a guy had his e90 330d 231bhp mapped with 335d injectors are achieved 350bhp i can only assume a hybrid was used..

momo Posted April 10, 2013 Report Share Posted April 10, 2013 How many 330d's have these companies tuned? Can they get a hold of them so you can have a look over them? Doesn't make sense to me.. Surely you need to up the fuelling to get more power (reliable) hence the injectors. Link to comment Share on other sites More sharing options...
bungers Posted April 10, 2013 Report Share Posted April 10, 2013 I've done a lot of digging around ref injectors, I ended up getting very confused as the part numbers for the x35d injectors show that they are used across the x35d, x30d & x20d engines. I believe you need the earlier 535d injectors to be a straight swap into the e46 330d's though. I too have read conflicting reports ref the need to upgrade the injectors, obviously more fuel flow is better but when a 335d can be mapped to circa 350bhp & has the same injector part number as a 330d then I start to wonder.

L333JSA Posted April 10, 2013 Report Share Posted April 10, 2013 E46 330d Injector Part Number - 13537794334 E90 330d Injector Part Number - 13537809193 E90 335d Injector Part Number - 13537808094 All different part numbers. Yes its the very early 535d injectors that are needed. On most remaps its just the injection time that increased for it squirt in more fuel. You can also increase the fuel rail pressure which will in turn push more fuel in per injection which could be what is done to get the higher figures - this obviously puts more strain on the pumps etc aswell. So do you spend more money on injectors or do you cross your fingers and hope that your pumps hold out if they are ran at a higher pressure - swings and roundabouts really.

bungers Posted April 10, 2013 Report Share Posted April 10, 2013 I'm bookmarking this! This was the part number that confused me: 13537809194, used on both the single & twin turbo engines: Part 13537809194 (Rmfd Injector) was found on the following vehicles: E60N 530d Sedan, M57N2, Europe (NX71) : High pressure accumulator/injector/line E60N 530d Sedan, M57N2, Europe, RHD (NX72) : High pressure accumulator/injector/line E60N 530xd Sedan, M57N2, Europe (NY71) : High pressure accumulator/injector/line E60N 535d Sedan, M57N2, Europe (NX91) : High pressure accumulator/injector/line E60N 535d Sedan, M57N2, Europe, RHD (NX92) : High pressure accumulator/injector/line E61N 530d Touring, M57N2, Europe (PX71) : High pressure accumulator/injector/line E61N 530d Touring, M57N2, Europe, RHD (PX72) : High pressure accumulator/injector/line E61N 530xd Touring, M57N2, Europe (PY71) : High pressure accumulator/injector/line E61N 535d Touring, M57N2, Europe (PX91) : High pressure accumulator/injector/line E61N 535d Touring, M57N2, Europe, RHD (PX92) : High pressure accumulator/injector/line E63N 635d Coupe, M57N2, Europe (EA71) : High pressure accumulator/injector/line E63N 635d Coupe, M57N2, Europe, RHD (EA72) : High pressure accumulator/injector/line E64N 635d Convertible, M57N2, Europe (EB71) : High pressure accumulator/injector/line E64N 635d Convertible, M57N2, Europe, RHD (EB72) : High pressure accumulator/injector/line Link to comment Share on other sites More sharing options...
L333JSA Posted April 10, 2013 Report Share Posted April 10, 2013 Yeh I believe they are all referring to the later 5 & 6 series arent they - the later E60 and E90 cars run different ECUs apparently hence having different injectors to the E46 with the same sized engine.

bungers Posted April 10, 2013 Report Share Posted April 10, 2013 Ahh right, that'll explain it. It would seem that the single turbo injector would be more than comfortable with remapped twin turbo power? Wonder if the nozzles are interchangeable?

L333JSA Posted April 10, 2013 Report Share Posted April 10, 2013 No idea - easier and safer just to get early 535d injectors/nozzles I reckon Link to comment Share on other sites More sharing options...
n0v0s Posted April 10, 2013 Report Share Posted April 10, 2013 (edited) If you are going for ~300, i'd stick with standard turbo/injectors and accept a lower bhp figure (say 290bhp) to maintain reliability and save money. if you are chasing bigger figures, then - bigger compressor and turbine on the gt2260v. Get the housings machined. Larger nozzles - 535d. If you understand anything about direct injection diesels, you'll understand that getting the fuel in within a certain injection window becomes increasing difficult when pushing on. I would rather run 535d nozzles on a properly calibrated map vs stock nozzles on a 300bhp m57, if given the choice, excl cost. The stock nozzles probably could be extrusion honed to effectively widen them, but it would be pointless seeing as we have 535d nozzles ready to go. I'm assuming the 535d engine utilises similar piston dish form... And so spray angles? Rail pressures can be increased as mentioned, the new cp3 pumps run 1800bar easy vs our 1600 iirc. Find yourself a gd tuner. Someone who understands properly about diesel tuning principles and go from there. Also, don't forget the newer gen3 common rail m57n runs a much newer style vnt gt2260vk. Supporting better flow. They also have the piezo controlled injectors - no idea with regards to nozzle differences compared to e46 m57n. However, if the same - then maybe the fact they can readily hit over 300bhp lies with the faster response time of the injectors getting the fuel in that bit quicker, or higher rail pressures which I think would effectively do the same..?

TriggerFish Posted April 15, 2013 Report Share Posted April 15, 2013 (edited) To clarify, you're swapping a 184 with a 204? Or is it another 204 going in? Interesting read regardless though! Edited April 15, 2013 by TriggerFish Link to comment Share on other sites More sharing options...

jassi Posted April 24, 2013 Author Report Share Posted April 24, 2013 Ok my turbo has been sent off to be hybrid converted, spoke to a couple of live mappers who have advised against 535d injectors, they stated that the 330d injectors are more than capable of doubling their flow.

bungers Posted April 24, 2013 Report Share Posted April 24, 2013 Good news, what do they think is the limiting factor for huge gains, turbo? Link to comment Share on other sites More sharing options...
jassi Posted April 25, 2013 Author Report Share Posted April 25, 2013 They said the turbo and the clutch is a limiting factor plus by putting unnecessary 535d injectors in you stand more chance of over fuelling the engine at the same time they did say that not saying they cant work but not really beneficial as the standard ones are more than adequate. Clutch upgrade is a must though as otherwise you will get pure clutch slip every time the torque builds up. Link to comment Share on other sites More sharing options...
Mick.H Posted April 25, 2013 Report Share Posted April 25, 2013 Looking to get rid of my 530D and get a 330d touring. So going to keep an eye on this thread, as its the route Im likely to go down. Any recommendations on tuners? Ive seen MSD mentioned elsewhere. Link to comment Share on other sites More sharing options...
