E87 120D n47 tuning.

Post by E87//120D_Tom » Thu Sep 27, 2018 12:48 pm

I have several questions regarding my 120d and it’s limits etc.
I’ve had the car roughly 6 months and it’s running 220bhp and 460nm.
I’ve serviced it giving it a major, Diff oil change and box oil change too.
I removed the egr and blanked it off using blanking kit. Cut the dpf open and removed intervals and welded back up. Removed and cleaned out intake manifold removing the swirl flaps. Then had it custom tuned by a local company who build race cars.
126k miles covered and original turbo and injectors so the tuner wanted to keep it reliable. He said I need to get injectors and turbo reconditioned or just refurbished. I don’t know what the processs is for either of those. He could’ve pushed it more but he doesn’t tune cars to blow up in 6 months time so that wasn’t appreciated.

What are the standard injectors and turbo capable of power wise? And what’s the cheapest way around getting these refurbished and fresh?

I’ve seen lots of talk about different injectors upgrading etc, so what injectors can I use, Ive seen lots about 535d injectors etc will these just bolt in and need mapping in and go.
What are the turbos good for power wise? Or should I be looking at upgrading.
I’m hoping for roughly 250bhp and 540nm to give you guys an indication of what I’m after.
I’ve seen an hybrid turbo on eBay which has warranty and claimed up to 60% increase on stock power, supposedly capable of 283bhp.
I’m not sure if this is any good or not, I know eBay turbo’s are far superior than they use to be but know there isn’t much of a market for upgrade turbos with the n47 is that correct?
Tuner recommended that I upgrade intercooler, Now what intercooler can fit and what modifications do I need to do to get it too fit? I’ve seen lots about 135i intercoolers fitting, but unsure what I need to do pipework wise to allow these to fit. Is it just couplers I need to adapt between sizes or?

I’m a vehicle tech by trade so majority of work carried about by myself. EGR delete and dpf cost me £50. So fitting of injectors and programming etc would be done by myself.

So main questions. Cheapest way to sort injectors, turbo and intercooler out. Or would I be better of reconditioning the original. Are 535d easiest and what do we think to this eBay turbo? https://rover.ebay.com/rover/0/0/0?mpre ... 2907972972
And is 135i intercooler easiest to use.

I can get hold of injectors and intercooler fairly easy just want to know what’s the easiest and cheapest route.

Hopefully this all makes sense. Many thanks for any help in advance.

Buy a 123d otherwise its just not worth it imo. you can get 340 bhp all day long with standard turbos and the right bolt ons

Insurance was only thing holding me back with 123d, they wouldn’t touch me at all.

But it’s something I can aim towards I guess, I didn’t know the 123d’s were so capable. What do you call the right bolt ons? Thanks

Extremely capable and way more reliable than the petrol version.


Intercooler
HPFP
Downpipe

etc

What injectors fit these? I have fitted upgraded intercooler and want to upgrade the injectors and turbo. what can I do turbo and injectors wise? What injectors fit? I’ve seen a n47 on YouTube make 300bhp with f30 320d 184bhp injectors is that correct? But then seen loads of mentions about 335d or 535d injectors not sure which. Can get a hybrid turbo fairly easily. Just want to make 250bhp and 500nm

With that comment, then I guess you're not declaring your modifications to the insurers. You'll have a right shock if you get into an accident, and the insurer comes out to survey your car and void it on the spot due to the modifications.

You cannot possibly put loads of power through the 120D gearbox and not expect problems. There's a reason BMW used the 3 series gearbox on the 123D.


I personally wouldn't bother "tuning" a 120D. Invest into a better model. You're just ruining the value of the car, I wouldn't buy a 1 series with a decat or remap, its clear with them modifications you're buying a boyracers rallied pile of garbage. You have the N47 engine also, which is a notorious engine for issues with the timing chains, which are at the back of the engine.

Nope you assume wrong. There’s no point not declaring, declaring is far cheaper than buying and insuring a faster car.
Remap etc etc was £50 extra for the year, covered up too 230bhp. a 123d with less horsepower, Was £780 extra for the year. That’s why I have a 120d.

I agree yeah, The cars on 132k, it’s not got much value anymore and didn’t buy it for very much either. I look after my vehicles and always do prevention work before something goes wrong, I’m extremely paranoid like that. Timing chain has been done I think it’s just case of looking after the car in the right respect. It’s a car with a bmw badge so won’t drop below a certain value in my eyes.
I want to keep the car for years as I can’t go too mad with it and can’t spend too much money on it, unlike if I had 330d.

So in my eyes it’s perfect.
Just want a little more power and an LSD haha.

If you know anything about tuning diesels, then you know the BHP figure isn't as important as the torque figures.

The standard 120D has around 340 Nm of torque. The 123D has 400 Nm, 295 ft-lb standard. I'd take a remapped 123D over any 120D. I'd have the 2010 or newer 123D.

Who’s you insurance company as I would ask them again as well as getting it in writing
Most will not allow any more than 20% more power

Your insurance company are saying 30% more is only £50 ?

Quick question. What can a 120d with the supporting mods I’ve done make like pushing it a little? regularly serviced using millers etc.

It depends on who’s dyno it is tested on
My dyno reads 10-15bhp less than most of the others

The best thing would be to bring your car down and test it on our dyno to see what it’s making 1st on our dyno then we can advise you what can be done

I normally see around 220-225bhp with 340-350ft on a standard car with the dpf still fitted
ImageImage

So should be able to get more out of yours
