LS3 Swapped E36 M3: On the ground and running!

Published: 12-23-20 17:00:00

Our LS3 powered E36 M3 project is finally on the ground, running, and ready for some more paint!We are using an LS1 PCM with a customized engine harness to run the LS3. This requires swapping some sensors, and using the 24x tooth LS1 crankshaft pickup, but allows us to retain the simplicity of the LS1 operating system/emissions, and retain cable driven throttle.This car will be receiving a custom widebody using OEM fender flares, for a clean look and much more tire capacity than factory. 😉Ult...

E36 318Ti Build: Suspension

Published: 12-17-20 14:00:00

There are many ways to make a car fun to drive, but in my opinion, a proper suspension setup is the most important thing to focus on before anything else. If you want a car that feels legendary to drive, the suspension needs to respond exactly how you desire under aggressive driving conditions. That means using the proper components and adjustments for your power level, driving style, tire compound, budget, etc. Quite a few vehicles are out there with heavily modified power-trains, but stoc...

350Whp N52 and how we got there!

Published: 01-12-21 14:00:00

Recently, we had a 2007 328i dropped off, featuring a centrifugal supercharger setup. After coordinating with the owner, we came up with a plan to spice things up a bit for this non-M underdog. A bit of back ground on the car:ESS supercharged 5.5psi3-stage IntakeF30 Sport BBKM3 brake boosterKoni nonadjustable struts Modified Akrapovic exhaustWe took the car and immediately baselined it. The mighty N52 managed 271 Whp and 237 wtq. A relatively respectable number on paper considering these...

22RPD Fuel Pump Hangar Design

Published: 12-04-20 08:00:00

In 2019 we started using AEM's 400LPh fuel pump. This is an upgraded version of the legendary Bosch 044 pump. We have liked them so much we decided to design a plug and play solution for the e36 platform. In this article we will discuss what makes this pump exceptional and we will detail our new solution for the pump in our e36.Let's start with the E36's fuel demands:Now obviously all of these figures are hugely dependent on the turbo, cams, displacement, and so fourth. Regardless they are ...

E36 318Ti Build: Turbo-Back Exhaust System

Published: 10-21-20 18:00:00

Now that the turbo is located where it needs to be, it's time to begin fabricating an exhaust system for the 318ti! Exhausts come in all shapes and sizes, ranging from an obnoxious hood or fender-exit, to a subtle OEM style system.Factors including personal preference and performance goals ultimately narrow down the design to its final form, these are a few of the most significant influences:Exhaust volume - (Track requirements, neighbors, wife & kids, etc.)Desired power level - (D...

What is the "Supercase" Diff and Why is it a good choice?

Published: 10-14-20 19:00:00

The super 8.8 is the latest advancement of the classic 8.8" differential from ford. It was released on the S550, 2015+ mustang. The original design was released in the 1980's as a solid axle and revised over the years with the same generic setup evolving into the popular 8.8-IRS in the late 1990's. While the late 90's 8.8-irs is a popular (easier) swap it is becoming more difficult to find. More importantly the latest revision is significantly stronger. The super case diff was initially rep...

E36 318Ti Build: Turbo Mounting

Published: 09-14-20 17:30:39

When it comes to turbocharger setups, the possibilities are nearly limitless, but some choices can make the endeavor more or less of a challenge. One of the first questions that must be answered is whether the turbo will be a 'top mount' or 'bottom mount'. Let's begin by discussing some of the benefits and drawbacks of each option:Top Mount     Pros:Flex-Factor, the turbo and downpipe will be very visible which can be a heavy influence for show oriented buildsEase of access to tur...

LS3 Swapped E36 M3: Intro

Published: 09-03-20 13:20:00

We love our BMW engines, of course, but in some cases a V8 power-plant may be exactly what the E36 chassis needs. A 1995 M3 arrived at our shop as a bare shell, along with an array of parts including an LS3 crate motor with a Vorshlag swap kit, T56 Magnum transmission, and Moton Clubsport suspension!The goal for this build is to create a dual-duty streetable track toy. In addition to maximizing the limits and performance of the car, we will be retaining comforts such as air conditioning, and a r...

E36 318Ti Build: Microsquirt Standalone ECU

Published: 08-20-20 16:04:00

Many 4cyl owners choose to swap their cars with the 6cyl engine because the conversion is essentially “drop in” when using the correct wiring harness, ecu, and hardware. It’s an easy way to boost the performance to essentially M3 level, but my goals are slightly different. I am concerned with balance, and more specifically, keeping the weight as low as possible. The M42 engine is a whopping 90lb lighter than an S52 engine, and this fact alone is why I am choosing to retain the 4cyl configu...

E36 318Ti Build: Intro

Published: 08-04-20 11:01:32

Let me roll into this series with a small intro: I'm a sleeper BMW enthusiast, G-force addict, and engineer at 22RPD. I will be using this blog to provide updates to projects, technical information, and hopefully some inspiration. My goal is to update this 318ti series at least once every two weeks with a healthy dose of substantial and aesthetic progress. I was looking for a fun and cheap daily to keep miles off of my E46 M3, when I stumbled upon this listing for an E36 318ti. Until now, I had ...

What is AFR and what should my AFR be?

Published: 11-10-20 08:00:00

We get asked this almost every day, so we thought we would outline what afr is and what you should be seeing!Internal combustion engines use fuel and air (oxygen) to produce energy through combustion. To optimize the combustion process, certain quantities of fuel and air need to be supplied in the combustion chamber.Air-Fuel ratio or AFR is the ratio between the mass of air and mass fuel used by the engine when running. We measure this with an exhaust probe called an O2 sensor. This sensor measu...

Welcome to the new Blog!

Published: 07-24-20 21:00:06

Congratulations! You have found your way to our new blog!This blog is something we are really excited about. It's no secret that in recent years, automotive forums and other places where we used to share what we have been working on have really dissolved. The replacing mediums leave us in a bit of a position where we don't feel like we can share some of the really exciting things we are working on, or show you the process it takes to really get to that finish line. Sure, we post some pictures to...
