What a journey ๐Ÿ˜…๐Ÿ˜‚ Lets not talk about the past!

My 2016 RS 15,000 miles now has the 2.5L engine from SP3 and if you want to learn about that engine, you can read about it here. Nishan, Jorge and everyone at the company has been great! 5 Stars. I was originally going to get the 2.3L engine but as I browsed the site I found the 2.5 and then I ended up upgrading to that. Also the folks at XDI have been great too.

What sucks is that I do not have E85 around here. It is not as easily accessible as in the United States so my power level will be lower that what i would otherwise be able to achieve. I am limited by pump gas 91 and WMI. So the engine may be considered overkill but oh well it runs and runs nicely.

XDI EVO pump : At 200bar of pressure, the EVO pump flows 12% more than the XDI35 and 41% more at 240bar pressure.

XDI injectors : 50% more flow than OEM XDI-i010-50-4

Fuel Injector Technical Data:
  • 50% more flow than OEM
  • OEM 122lb/hr @ 100bar

  • 2000cc/min at 100bar, 2880cc/min at 200bar
  • 179lb/hr at 100bar, 253lb/hr at 200bar
  • Stable at 200bar even with OEM driver settings, completely linear flow

Quality Control:
  • Every injector flow tested on XDI proprietary DI test bench at
  • 0.8msec/20bar for idle stability
  • 10msec/100bar for static flow reference
  • 6msec/200bar for WOT performance
  • Every set high pressure matched within 1%
  • Every injector type validated for identical SOI and EOI via XDI proprietary injection rate measurement

Other Parts installed:

The install went smooth,

I ran into the issue with the turbo manifold not mating well to the due to a bolt that was disturbing and found a thread about it and did the same and now it is happily seated. The thread is over here. Got some pictures added to it. Came out well.

I then installed the transmission and realized i did not see the centering guides on the block and also realized it was missing for the starter too so i had some fabricated. So i removed the transmission and sorted that out and installed the guides.

Engine was then dropped in with PTU and transmission bolted to it. I also put on the PTP turbo blanket and wrapped the downpipe with titanium wrap from autozone. Now that the car runs and no weird noises like the Esslinger Engineering engine, it is noticeably cooler under the hood too. I was impressed with heat reduction and more impressed as that means less hot air gets sucked in to the engine.

I then added the Wire harness and connected everything. Oh, first i wrapped the wire harness with tesla tape 51036. That was some awesome tape made for wire harnesses. Awesome stuff. then I bled the brakes and clutch using the pressure pump and used MOTUL RBF 700 fluid. Used the Orion Motor Tech Brake Pressure Bleeder, they also sell a cap with a 90 degree bend as it would otherwise not fit unless you remove wiper etc. It was super easy to use...

I then had to install the XDI pump and the issue here is the hard tube. I had updated another thread and added pictures their. It turned out great, just need to be patient. I used a new tube and practiced on the old one first lol. Here is the thread.

While at it i also added the radium catch can drain so i don't have to remove the can every time like before as it is in a tight spot between the battery and the hpfp. Cleaned and oiled air filter, changed the radium fuel filter, added 21oz of AC refrigerant. Also all bolts I torqued to spec and marked them for visual check later if needed.

In February i will need to get a new set of Michelin PS4 tires. Mine have good thread but having been out of service so long and little use they have cracks in rubber but not sidewall. Either way, deserves new tires and i will feel safer when we start tuning.

Also ordered Mishimoto MMODP-12175BBK magnetic oil plug just because i felt like it ๐Ÿ˜‚ and waiting for the dsc controller that a member here sold me and shipped it. Entered customs oops. Was hoping it does not but oh well, we will see what they tell me.

I put the 10-40 Motul Break in oil and had to have it imported as they do not sell it down here I searched and even emailed MOTUL in Mexico and no go. I ran the cams for around 25 minutes between 2,200 rpm to 3,000 rpm to break them in. Now i am in the process of doing the engine break in. Every builder has their way, speed performance have it 1500 miles before tuning and WOT so I will get the miles as fast as i can lol. The first 50 miles i guess are the most important so i did my best accelerating up the gears to 3500 rpm and then engine braking and repeating the process.

Runs good, and i cant wait to red line it when it is time just to hear the sound lol.
