Build Thread...Project M4 GTS: Alpine White

[RSXDC5]

This looks like the 4N Motorsport kit. This is the ideal single turbo kit at the moment.

You got it...this is the latest 4N Motorsports kit. Best on the market at the moment. All other vendors have the shorty manifold which is mehhhh.

One item to note with the 4N kit. Their standard heat shield should work ok, but if you really want to manage heat under-hood in a Motorsports environment, you would want the manifold/hot side turbo, and maybe the DP wrapped by Headershield (US based vs Good Fabrications which is UK based…although you can do Inconel shielding w/ Goodfabs!)

Check out these companies on Instagram for their work, you will be pleased!

I have all that covered. Their new kit has a better heat shield for the manifold which was designed for the track day enthusiast in mind. The turbo will have a carbon fiber blanket and the both the manifold and DPs will be coated to reduce heat.

A Funk Motorsport turbo blanket?

On 2nd thought...my tuner is insisting I go PI especially for track use. The MHD and Reflex+ would control the external wastegate, PI, and ethanol mix with all safety measures in place.

The setup would consist of the following:
- BMP PI Kit w/ 750cc injectors
- PR HPFP Stage 3 Brushless w/ fuel line
- Reflex+ w/ data cable
- Ethanol Sensor w/ 0-10 bar pressure sensor, sensor harness which will be directly connected to reflex+
- NGK 2 step colder plugs for e85 12120042724

[Wanted_M]

Sick build bro, I may pay 4N a visit to check out their shop in Placerville which is about 2hrs from me. I think you meant PR LPFP, from what I hear Reflex is bad arse.
Who's tuning it?

[JustAnothaM4]

Yeah I would definitely check them out. They have a pretty good product with the latest revision of their single turbo kit.

PR Low Pressure Fuel Pump. Yes, Reflex+ is good!

Did you get the 4N turbo kit installed?
I'm eyeing the 8474 kit.

No, im still waiting on my EFR 8474 kit to finish getting built and shipped. I opted for aluminum CHRA and its taking a bit longer vs more readily available iron CHRA. I'm also doing a custom single titanium exhaust.

[JustAnothaM4]

Welp...I'm a slacker and haven't updated the build in a while.

I did a ton of suspension upgrades over this past winter. I replaced all rubber bushings with SPL arms and spherical bearings. The biggest improvement was switching over to Ohlins TTX dampers w/ Swift springs. I also added another set of BBS E88 wheels for street duty.














Track Day Prep for May 2022 Event:

New Helmet!!






Removed stack height spacers on Ohlins TTX:

. . . switch to Alcon or AP Racing BBK

If you are going to switch to an Alcon BBK then run 11x18 wheels and 305/35R18 tires. This will give you a rotatable set of wheels and tires.

Bimmerworld is releasing their TA16 forged wheel in 11x18 ET36. You will need a 12 - 15mm spacer up front. A lot less money than the overpriced BBS wheels.

Best GTS in the country!

Great looking build! I'd love to hear your thoughts on the 4n kit once you receive and get it installed! Particularily what all is included, and what (if anything) you had to fab up to integrate it into your car.

Updates coming soon…I've been slacking again.

The turbo kit has been here and I'm just getting all the supporting pieces together for install.

Looking good! And thanks for documenting your build, I know it's a lot of extra time on top of doing the actual work, so I really appreciate it. Great for the community!

[Owo-Nikoko]

Damn this is really impressive

[JustAnothaM4]

I haven't updated this thread in a while...but I did a crap ton of upgrades...

My BBS obsession continues..S/O to Brett aka Slicer on the Gold E88s and Gold RIAs!








Also picked up a couple of cool carbon fiber pieces from SLON!

- Upper Tie Bar
- Front Bumper Support Brace




Paint matched Flossman Carbon Fiber Fenders:
