I also collected info about the Opel injectors:

-E85 capable
-working up to 350 bar
-around ~1400cc flow @ 100 bar
-can support 500+ hp with pump gas (depending if the hpfp flows enough)
-Can be used for minis and vw tfsi engines as upgrade
-part number: 0 261 500 112

I have finished the downpipe, the exhaust and fitted all the other missing stuff. I also fitted two catch cans. Here's a picture of the engine bay.

I let the car run for 20 minutes with various revs and did an oil change. Then I took it for a drive. The engine runs good with a few hiccups.

The logs showed that the engine runs to a lamda of 0.60-0.50 which is extremely rich. The bigger injectors have to be the cause of that.

Otherwise the car doesn't feel different except for the turbo. It surprisingly spools as fast or faster then the jcw turbo even with it's way bigger turbine and compressor. That thing took me by surprise as it spooled like there was no tomorrow.

Now it's time to get the ecu programmed.

Great work and mods on the car.

Are you using the OEM ECU or standalone and who is reprogramming the ECU for you?

Will you be putting the car on a dyno to see what power it makes when you're finished?

Are the injectors direct plug & play replacements or do they need modifying to make them work?

Iam using the oem ECU, a Delta ecu would cost a huge amount of money and is (in my opinion) not necessary for my power levels and modifications.

Fotis from revlimit is going to setup my mapping for the ecu.

They rail has to be modified to fit them because they have a plastik Pin to keep them in position.

The mapping has to be adjusted, because the injectors have way bigger flow then the stock ones.

The engine runs, but very rich lamdas up to 0.55 at load.

Yes Dyno numbers will soon follow when the mapping is ready!

hello, very nice project

i'm looking for information for my project so i have some questions

this in the PSA prince engine ? ( ep6 series)

for a simple stage 1 + e85, do the hpfp need to be swap ?

the modification on the rail for fitting the new injectors is simple ?

Very thx

It's the psa engine.

The railmod is quite easy.

I have no experience with e85, but the hpfp probably won't flow enough fuel.

very thx for informations,
do you know any model that will swap easily for the hpfp ?

 

[arke]

No unfortunately there isn't one.

Any news ?

I had some problems with the ecu and had to send it to Greece. It arrived again today, so I can start logging and get it done tuned.

What's in Greece and the ECU ?

My ecu software developer. The mapping is done by revlimit.

First Logs with the base map. The diagram below is a fourth gear pull from 1500 to 6700 rpm.

Full boost is at only 2300 rpm. What's really noticable is that the fuel pressure drops as soon as the boost comes at low rpm.

Looks like the stock pump already reached it's limits. The pump isn't spun fast enough at low rpm to keep up with the fuel demand.

The new pump solution has to come soon.

The development of the final software does last a bit longer then I thought.

Especially because the battery died on me and i had to replace it. Instead of an 55aAH i went to an 80AH battery.

The oil has to be replaced again. I found an oil I wanted to try, especially because it is sn+ specified.

There is an event next week on the GP part of the Nürburgring, so I thought i would be great opportunity to fit my suspension upgrades.

So the development of the mapping last more then I like it...

Mainly because of a few issues that needed to be sorted out.

The problem is that I get the P1947 code. I checked everything for leaks and my valve cover is new.

I can't find any leaks.

The only "leak" would be the blow off valve, which vents to the Atmosphere.

Any idea what the culprit could be?

I haven't posted anything in a long time as nearly no progress has been made.

I had to change the maf and modified the catch Tank system.

The biggest problem was that we couldnt flash the ecu. Well we could flash it but the manic map was always present.

I had to get it to my old tuner to Reset it to stock.

After that we started with the logs and tuning.

One problem was the closing throttle body because the ecu didn't want the higher boost.
Revlimit fixed this issue. Now the thing can boost till 2 bar.

After that appeared the next issue. The diverter valve starts opening up when the engine exceeds a certain boost pressure.

I wanted to use the stock Peugeot diverter Valve and body.

Now it looks like I have to ditch the system and install a mechanical one. My tuner has to delete afterwards the electrical solenoid from the system.

Well if I had knew this beforehand I would have had less work .


As for the engine, it runs good and the bigger injectors don't make any issues. The fuel consumption is normal as well.

A new update will follow as soon I find a solution for a new blow off system.

So I found a solution for my blowoff problem.

I wanted to keep the Peugeot blowoff, so I didn't have may options..

I bought another GFB DV valve, but this time the n18 version which is being controlled remotely.

But connecting it to the intake manifold isn't going to make it work, because I can't change the spring rate to set it up to my boost pressure.

Andy Redz recommend a special forge valve which utilizes the pressure difference between the turbo outlet and the manifold during lift off.

Thanks for that Andy!

The blow off valve can be controlled like the GFB DV with the electronic actuator.

It can be installed even without any spring at all

On the n18 GFB are two connectors. The one in the center is controlling the piston and it's going to be connected on the single port of the forge valve.

The outer one is just a boost tap and it's going to be connected on the lower port of the Valve.

With the Valve came a few metal t-pieces. iam going to connect this to my existing Hose which is mounted on the intake manifold for the final connection on the forge valve.

With this we will be able to deactivate the electronic actuator.

Unfortunately my hpfp died on the way to my workshop. I managed to get there but the pump only delivered 800 kPa.

Iam going to look more into the pump tommorow. Maybe there is some life left to her. If not I will have to buy a new pump.

I will also adapt my jcw kit airbox and modify it a bit for more flow.

I will dyno the car and compare directly the m7 super ags open airbox with the modded jcw kit airbox to see if there is any difference.

If the difference is below 5 hp I will ditch the m7 one, as it is illegal in Germany.

Alright the new blow off system with the modified GFB valve and the forge intake pressure compensation valve works!

It holds 29psi without any issues and without the ecu opening the dump valve.

I also did tidy up the engine bay and made it more stock looking.

I will also modify the airbox by 3d printing some bigger intakes. More will follow soon.

The repaired fuel pump worked until my new pump arrived today. I think it's not that hard to repair them but I would still consider a new one.

The forge valve can be seen next to the catch Tank in the engine bay.

I didnt like the idea of having nearly 30psi in the Valve cover because of the crankcase ventilation so I blocked it with the Peugeot covers of.
