Cool Custom Turbo Upgrade Journey! - 04-09-2020, 10:54 AM

Good day all, I am delighted and excited to post this! I have been gathering parts for awhile, now I think I am at the point of dropping the oem turbofold and begin install of my custom kit. The attached pictures show the pre-fab. work I've done thus far. I am awaiting a couple more elbows to compete the last runner then I'll be doing fitment and any needed adjustments ( my car is RHD) and final welding. Once this milestone has been accomplished the rest will be fairly simple.

No one interested enough to post something? Makes me wonder if I should even bother to share!

Based on the much complimented performance of the 8374 as illustrated on many a dyno graph as well as the advertised 22% improvement in flow for the same turbo size I think it will be a great match for the N55! But time will tell.

I am at work for the next 14 days so there’ll be no more updates until then.

Looking forward to seeing more of this.

Stupid question: Is that manifold made for top or bottom mount?

Hi it’s bottom mount, I prefer the stealth OEM look and I don’t care for any heat related issues.

Hi, as of now I am awaiting delivery of the weld elbows I need to compete fabbing the last runner of the manifold then I'll remove the stock turbo and begin final fitment of the manifold. In the mean time I have done an MHD flach+ BMS BEF along with an XHP TCU FLASH in preparation.

Update!....... nobody told me that reliving the stock turbo would be so torturous!!!! But I did succeed! Tried fitting my manifold, but I can’t even get it past the subframe! Guess I’ll be relooking the design..

......So after trying for some days without success I finally accept that a long or medium runner manifold is NOT going to fit in the same space with the steering shaft there, yes my car is a European RHD version. I have decided that in order to fit everything in the space and keep the original motor mount I will have to settle for a simple log style manifold much like the stock turbofold. Presently I'm paused waiting for a couple pipe Ts to arrive before I get be back Into it!

Need validation much!?

Dope setup, looking forward to seeing this completed. I like that you're sticking with the bottom mount, I plan to do the same.

Thanks! Tried to buy the manifold separately from Jeff but he refused to sell it to me, I’m grateful now because it would’ve worked!

Initially for a short period of time I think he was selling the manifold alone, but now I think he want to reserve all his limited stock for the complete kits.

How much power are you aiming for with your setup ?
