main parts i got so far:
- Motiv Reflex+
- Pure Stage2 Hi-Flow Turbos
- BMP 650cc port injection (for meth)
- Precision Raceworks Ignition Coils
- VAC Stage2 cyl. head (ferrea valves)
- AEM meth pump
- CSF Radiator
- Mishimoto Oil cooler
- BMS Trans cooler
- RB PCV / Mishimoto catch can
- HKS BOV
- VRSF Chargepipe
- VRSF 7.5" Intercooler
- VRSF Catless DP
- VRSF Outlets
- MMP Inlets
- Walbro 450 fuel pump
- 6 new OEM Index12 injectors
- ECS stage3 Suspension refresh kit (will upgrade some bushings and arms before install)
- ST Coilovers
- Stoptech rotors + EBC red pads
- ZF Trans solenoids
- 2x OEM Vanos
- all internal engine seals/gaskets/bearings/rings
- bunch of new sensors
- CIC unit/controller
- STI-R+ radar detector
- ALP laser jammers

teardown starts

[PS2N54]

wire harness off

[PS2N54]

front suspension, exhaust & driveshaft removed. under carriage stripped.

(going to drop engine, subframe + trans as 1 piece)

[PS2N54]

engine & trans are out!

PS2N54 -
This is insane!
"Some assembly required"....(and disassembly).
This is an entire car rebuild - such an undertaking, for sure.
An impressive list of upgrades and replacements - wow.
Was the underside of the hood taped over the holes in the structural elements to prevent any debris from potentially falling into an "open" on the engine?
Is this a 7 speed DCT transmission?
Tell us about the solenoids you are replacing on the transmission.
Definitely interested in your project and really want to tune-in and watch this incredibe "refresh/rebuild"....

UPDATE:
Just did a search and read about the turbos and cyl head....this is incredible!
This is going to be a rocket-car.

it took me about a year to collect all the parts, many thanks to people on here.

the tape on the hood is to prevent scratches from my magnetic flashlights that i kept moving around.

the trans is ZF 6speed, next phase of build iam hoping to switch to DCT - for now iam changing all the shift solenoids and main oil pressure seals inside and flashing trans with XHP to get slightly more aggressive shifts.


i got engine on a stand and trans put away for now, next few days is just going to cleaning the frame and engine of the car before further disassembly. iam trying to buy a kid's swimming pool in middle of winter to use as a catch for washing the frame/engine inside my garage

Thanks for the update - love the kid's pool idea - brilliant as it is formable and large enough to catch the cleaning process.

My 13 335is E93 has 38K miles and will have the 7 speed DCT refreshed at 40K miles; love how incredibly fast the DCT shifts - its really incredible.
-I am considering this upgrade https://burgertuning.com/collections...ke-for-n54-bmw
-It appears you have these type air filters on your car.
-I always thought under-hood air was hot which detracts from engine air filter inlet performance of the engine.
-Is this type of twin filter successful b/c the stock filter box and filter box silencer, etc is so restrictive that by removing the stock filter box and utilizing twin filters under-hood that it provides the HP and TRQ increases?

Thank you for answering such an elemental question -

at idle and very low speed is really when it will pull in hotter air, the front air scoop+cowl brings good amount of cool air when car is in motion.

without the box for sure less restrictive, not sure about hp/trq increase on its own, but along with other mods that would demand for increase air supply, it's necessary.


iam likely going to create a custom scoop, heat shield and possibly try divert air from the brake cooler duct or add ducting where foglights go for increased cold air flow.

The proper way to remove an engine, with the entire front end removed!

Thanks so much -
I ordered the https://www.turnermotorsport.com/p-5...ir-filter-kit/

The Burger Motorsport site has a link to a zillion discussions re under-hood hot air vs performance gains of the dual cone inlet air filter system - your perspective is valued.

Brilliant idea to utilize an existing cold air duct (front brake air duct) - perhaps you can post these mods as your build continues.

[PS2N54]

almost finished removing accessories etc..

[PS2N54]

figured a cheap and effective way to plug the holes on the block before doing preliminary wash down of the engine before further disassembly.

i stuffed papertowel/gloves into the hole, then filled top with hot glue. tested and works good. comes out nicely as 1 piece too.

CRC brake/parts cleaner caps are also perfect size for covering exhaust ports (i further sealed with hot glue).

[PS2N54]

wash setup

[racerbruce]

YAY!
The kiddie pool idea was perfect!

[Hollandazedd]

Looking good

[racerbruce]

What's the latest - hopeful for pics and progress.

[PS2N54]

mostly just been breaking my back cleaning years of oil/vapor residue off the chassis/wiring/hoses, got a bit busy with work too.

here are some pics of the front chassis cleaning progress.

[E93Seattle (Racerbruce)]

Ummmm....lemony fresh!
looks great; such a great place to start with - such an enormous project.
