Coming Soon: Technique Tuning E46 non-M Turbo Kit
 

Let me introduce everybody to the upcoming Technique Tuning E46 non-M Turbo Kit. This kit has been in the making for a long time, and is in the final stages of development and testing. Our test vehicle is a 2001 330ci 5-speed. In stock configuration, the car dynoed at 196rwhp and 198rw ft-lbs. After design, installation, and initial tuning of the turbo kit, the power numbers are now 318rwhp and 299rw ft-lb with 8.5psi of boost. The 8.5psi of boost was achieved using an electronic boost controller (not included with the kit). Running only off of the wastegate's 6psi internal spring, the power numbers were 289rwhp and 267rw ft-lbs.

The kit will be a total bolt-on package. No exhaust welding will be required; no bumper cutting will be needed. There is no ground clearance lost with the installation of the kit. The factory splash shield and brace are retained under the engine. The air filter is mounted high and away from possible low-level standing water. A Garrett designed T3/T4 turbo is used to provide reliable boost, while an external wastegate expels unneeded exhaust gasses to regulate that boost. The large front mount intercooler mounts behind the factory bumper using a laser cut and CNC bent bracket. Our proven blow-through mass air system is retained, which also allows use of a blow-off valve (included with the kit).

Of course, tuning is done via reflashing of the factory ECU and larger fuel injectors. The vehicle's original smoothness is kept. Driveability is just like stock. Until the throttle pedal is pressed that is, as that's when the fun really begins :) Full boost is achieved by ~2600rpm on the street. Part throttle boost is virtually instantaneous too, giving the car a V8-type of feel (as can be seen by the torque curve's shape).

Below are several dyno graphs of the results thus far. Here are the details for the runs:

We will be making minor tweaks to some of the components, and doing some more tuning to see if more power can be extracted. Pricing has not yet been finalized, but will definately be competitive (just like our E36 turbo kits). If there are any questions regarding the kit, feel free to contact me at nick@techniquetuning.com

this may be a stupid question, i have really never been that knowledgeable about turbos, but is a blow off valve like a replacement for a wastegate? is that why on cars that are stock turbos(such as audi's 2.0T engine) do not have a whistle when the throttle is released?

A blowoff valve is completely different than a wastegate.

A wastegate is used on the exhaust side and regulates the speed of the turbo by bypassing exhaust gasses.

A blowoff valve is used on the intake side and releases excessive boost pressure when the throttle plate is suddenly closed.

so a wastegate is like a boost controller? then do all turboed cars have blow off valves except some are louder than others?

will a steptronic take this kit?

xsperf, turbo audi's/vw's have diverter valves which are routed back to something so they arent blowing off to the atmosphere like a blow off valve so I think that's why they arent that loud?

Are there kits out for an e36 325i with the M50 motor. I know you have kits for the e36 m3's.

IF you ever want to steal my car and do that to and return it... I'd be more than happy, :lol

A boost controller can be used in conjunction with a wastegate, to run MORE boost. No boost controller means you'll running whatever boost level the wastegate spring calls for. Installing a boost controller will allow you to run more boost than the wastegate spring (but not less).

A turbo car will either have a blow-off valve (whooosh sound) or a bypass valve (virtually silent whiskkkk).

Eventually, yes. The kit needs some minor changes to fit the Steptronic platform.

No, we don't offer any non-M E36 turbo kits, sorry.

I'll keep that in mind :thumbup

What 3 series models do you think this will be available for?

you got an idea of price?

nvm i read the entire thing this time.

That would be so awesome on your car Rooz and yours too Numark.
