Hello All!

I have a 2liter HDi RCZ in Hungary, and I want to tune it for at least 250 hp.
We already did an ecu remap to 180hp, but the turbocharger and the ECU of the car did not liked the remap so I removed it.

It is believed that the stock fuel pump is good for 200hp, but not more, so I would need a new, bigger fuel pump. Which one would fit the car?
Also, I would need a bigger turbo, a bigger intercooler as well. Could you recommend some?
Would I need new CR Nozzles or not?
If some of you did a 250hp build from the HDi, please let me know!
Many thanks!

Hi and welcome, I haven’t heard of anyone taking a HDI to 250bhp there are a few petrol cars doing that and more.
Good luck with it keep us informed of how your getting on :thumbup:

Yes I knew that. removing the FAP, a big cooler and a good ECU remap and you are already at 200hp
Anyways I did spoke with some PSA Tuners and they say I need a big intercooler, a custom ECU remap with a hybrid turbo and the FAP removed to get around 230hp and 450nm of torque.
I do afraid from Hybrid turbochargers since they are not too reliable.

I read that reputable brands (BorgWarner, Garrett and Valeo) have hybrid solutions.
I think the turbo on the HDi is from Garrett so maybe their solution gives you the best reliability?

What was wrong with remap, I have 192 HP on my HDI, engine runs fine, if you remove fap filter you gain another 7-10 HP
There are some HDI 2.0 tuned to more HP with intercooler and nozzles changed, but I dont know if they last
Stage 1 is way to go, I dont know if pistons, camshaft, clutch etc can handle 250 HP

so you took 36hp by replacing the plastic pipes with alouminium, the air filter and the intercooler?
can you please tune my car too?

Stage3 is engine modified for race, so extreme mod, I doubt you know what this is, and that you have 260 hp on your engine
Stage1 with dpf 190 hp, without 197
If you remove dpf engine could be remaped to 200hp/207 without dpf
If you change intercooler + full custom exaust you get 10 hp more so around 217hp
Diesel engine needs special air filter, look at Peugeot/sport store
If you put k&N type filter or if you have other open air flow on diesel engines you could loose 20HP
And lastly with 260 hp this engine wouldn last, look how much effort has sport division put in R engine, and then you read horror stories even with stage2

Don't mean to revive an old thread but I found it an interesting read, mainly because I am looking to get my 2.0 HDi remapped.

Couple of questions, firstly the air filter if you put a K&N or a piper cross on the HDi it can effect BHP? I always though air filters didn't really add or take away much in the way of any BHP for an image and mainly made it sound nicer.

Next, what kind of BHP could I expect from a remap + a DPF pass-though/delete? and will that be safe for a stock clutch?

Would be happy if I could get to the 200 BHP mark with some nice torque... safely lol!

You can get to 200bhp with the HDI, I don’t think you need to delete the dpf either a good remap should do the trick 👍

I was told by a company that remap via the port can give extra 30bhp no problem without deleting dpf... Cost was £150 and that is all they do and have a good reputation for there work on performance cars

Remove the DPF system & boost BHP = Carbon build up at twice the rate of normal Engine operation plus extra servicing schedules to perform at lower Klms ?

Yes that is dead right when new oil is put into the engine it will run cooler & at a more efficient rate of performance due to the fact that the new oil is Lubricating at a higher viscosity due to its strength older oil left in a diesel or petrol engine for a long time will just make the components wet & deteriorates the lifespan of the running gear etc

Hi Again - well I was getting a couple of error codes P1447 and P1490 turns out my DPF is clogged, tried changing out the differential pressure sensor (sits behind the battery) before taking it to a specialist. So I am booked in to get the DPF removed and the ECU remapped :) hoping to get between 190 to 200 bhp but wont know till I get it on a dyno.

Will do Pedro although I don't think I do enough miles tbh I've seen on avg about 57mpg after remap and dpf delete. Hello I'll let you know about the black smoke allot of people think deleting the dpf automatically equates to black smoke the map has allot to do with it and how much fuel is being injected into the system. Clutch should beable to handel another 45 more hp, why should it not be driven below 1500 rpm and what do you mean by dmf?
