Important Auto Division Docs

(last updated Tues, Oct 13, 2026)


BIG Picture Perspective

We plan to build & sell 250 OEM+ 2006 E90 Restomods.

Our strategy is centered-on acquiring pristine, single-owner Automatics & converting them to Manuals.

We plan to list each of our Restomods for $50K+ USD.

Each will roll off the line with our Stage 1 tune.

After we list our 250th Restomod, we plan to offer a "Perf Kit" to the General Public.

For clarity, we picked 250 to honor America's 250th anniversary.

Also for clarity, we will do our best to obtain a CARB EO for our Stage 2 setup.

Our Prioritized List of what we're currently working on:

1.) Custom ML-based Alusil cylinder wall Reconditioning Service.

We plan to offer this to the General Public as soon as it is ready.

We're pricing it at $4,999 USD.

ALL we need is the customer's (~45 lb) bare Crankcase.

2.) Custom single-stage intake manifold.

📌 340 mm progressively-tapered Aluminum runners +
2.7L 3D-printed MJF PA12-GB plenum

● Total Length = 340 + 75 (head) + 15 (Bellmouth end effect) = 430 mm

● Raised, Full Radius 50 mm dia. Bellmouth

3.) Custom Stage 1-3 "Performant Daily Driver" tunes:

📌 Stage 1: 230 hp at 6200 & 200 lb-ft at 3250

📌 Stage 2: 250 hp at 6200 & 220 lb-ft at 3250

📌 Stage 3: 260 hp at 6300 & 230 lb-ft at 3500

● Stage 1 & 2 assume the stock exhaust.

● Stage 2 & 3 require MILVs.

● Stage 3 requires Catless Headers.

● For our Stage 1 & 2 tunes we recommend shifting at 6200-6300 RPM.

Due to backpressure, the stock Exhaust chokes past that point !

 ● For our Stage 3 tune we recommend shifting at 6700-6800 RPM.

● ALL three of our custom tunes have a built-in 3% safety margin.

On a cold morning along the coast,
you'll experience 206.0, 226.6, 236.9, lb-ft respectively.

 ● The design mimics a small naturally aspirated V8:

i.) ALL 3 Tunes have a compressed powerband.

i.e., they produce peak-Torque alittle higher, RPM-wise, than stock,
& peak-HP alittle lower, RPM-wise, than stock.

ii.) ALL 3 Tunes undercut the N54 manifold swap, RPM-wise.

4.) Custom forged 17x8.5 ET33 wheels for non-M E90s.

📌 Requires the M3 front control arms.

5.) Custom weatherproof Cowl (delete) solution.

5.) MSV70 Deep Copy Service.

The Timmy E/P Benchmark

Simply put, it's Efficiency divided by Perf.

We believe it has the potential to become a De Facto Standard.

Timmy E/P = (Range in miles at 85 mph) / (0-60 time + 1/4-mile time)

See the Coastal Cold Morning Performance table for reference
