Engine management / E36 dme "ecu"

« on: April 03, 2012, 03:13:24 PM »

Great idea!

Is the gasket in the second pic from between the head and lower intake on the
M42?

It would be ideal to use a map sensor based system to do away with the airflow meter. You may be able to maximize flow that way.

Do you have any of the Toyota ITB's available for purchase and do you have any plans to make up several adapter plates for sale?

Lastly, will the ITB's bolt up to any other Toyota engine?

Thanks, and best of luck. You are certainly on the right track!

Bump for update! Did you locate a turbo?

Can you please tell us specifically what the Toyota ITB's are from and what you have to do to mount them? I believe there would be a great deal of interest in these.

Thanks, Lee

Engine management / e36 M42 test engine

« on: April 01, 2012, 05:44:53 PM »

Thanks!

I think we might keep this one and make a one-off project. Running it on the chain is relatively easy and I will use this method to perform basic test runs for various mods such as single row timing chain, intake, turbo and ignition. Fabrication on most items will be a breeze while working at a proper height.

It is so much easier working on the engine when you can reach every part w/o bending over and having poor lighting in an engine bay.

BTW: looking to swap oil pans to covert for e30 use (need upper and lower); even trade if someone needs the e36 pan. E-mail is best: lee.johnson@rustdepot.com.

Swaps, Turbos, Buildups / Help M42 Turbo Fuel problem

« on: April 01, 2012, 05:18:33 PM »

1992 Saab turbo injectors are 22.64 lb/hr and work well for 5psi w/ no other mods. They provide approx. 12.5:1 air/fuel ratio @ WOT. These may get you close, then add other mods such as an intercooler and/or RRFPR for higher boost. Perhaps 7-8 psi.

Don't do anything unless you first have an accurate AFR meter. It is of UTMOST IMPORTANCE and will make it much easier to tune with less risk.

Swaps, Turbos, Buildups / m42 Turbo Flange

« on: April 01, 2012, 05:07:47 PM »

You can get turbo inlet flanges from most exhaust tube suppliers in either mild steel or stainless. For the head flange, I think there is someone here that makes them or may know where to get one. Anyone?

If you are on a budget, use the stock header, turn it upside down and mount the turbo to the chassis. For details, go to 'Stock header turbo build'

What turbo do you plan on using?

Swaps, Turbos, Buildups / M42 Intake port spacing

« on: April 01, 2012, 03:51:59 PM »

Does the M10 or any other engine (yes, even a six cyl.) share the same intake port spacing as the M42?

Thanks

Swaps, Turbos, Buildups / Stock Header Turbo Build

« on: March 08, 2012, 07:54:54 PM »

I've been away for a while.

Don't cut anything! We used a taller engine mount on the pass side and a lower mount on the driver's side to rotate the engine (clockwise looking @ the front) w/o the engine interfering w/ the hood. I will try to find out which mounts we used and post; I think a early 635 mount is taller. The driver's side may possibly be left stock, but I am not certain.

The most important part is making a mount plate for the pass side mount so it prevents stretching the mount. We have not done this yet. My son's car is in Daytona Fl. We will when he comes home for the summer.

There may be slight differences in the e30 and e36 headers, so keep that in mind. Perhaps others can provide pertinent info.

You should be able to run the t3 ok. It is a bit larger and will have a bit more lag; however they are easier to find and they have the same flanges. You will easily keep the t3 within a very efficient area of the map. Later on if you significantly increase boost you will most likely remain efficient.

T3 equipped cars may have had slightly different injectors. I am not certain.

Swaps, Turbos, Buildups / Stock Header Turbo Build

« on: February 07, 2012, 07:25:56 AM »

To help ensure success, I would invest in a AFX Powerdex air fuel ratio meter made by NGK, and weld in two bungs on the turbo inlet piping for the stock O2 and the wideband of the AFR meter.

If you want to learn more about turbocharging, read 'Maximum Boost' by Corky Bell.

Swaps, Turbos, Buildups / Stock Header Turbo Build

« on: February 07, 2012, 07:16:27 AM »

I can't locate any list on or off the forum. Here is a list of all that went into it.

1992 Saab Turbo: te05-12b turbo, fuel injectors, blow-off valve (cost: free, I own donor car; locally a turbo is $75.00, injectors and BOV about $20.00). The teo5-12b is not very common, but seems to be ideally suited.

Stock header: free, everybody has one, and it will outflow anything out there.

Stainless steel support for turbo: free, a friend fabricated it. A piece of mild steel channel will work fine for approx. 10.00

All header to turbo stainless piping, flex coupling, flanges: Approx. $125.00

Complete straight through 2.5 inch stainless exhaust from turbo to muffler incl. mild steel muffler, resonator: Approx. $200.00.

All turbo to AFM aluminum pipe, flange: free from leftover parts in shop, approx. expected cost, $35.00

K&N Apollo air filter kit: $100.00

RH motor mount from 635i to raise engine on that side to provide clearance for header. (NOTE: additional plate on crossmember should be fabricated to align motor mount properly otherwise it is stretched horizontally). Cost $15.00

Electric cooling fan: $25.00-$75.00 depending on supplier.

Boost gauge: (VDO) $35.00

Misc. hose, stainless hardware, gaskets: $40.00

Total approx. $705.00.  The previous estimate of $757.00 included stainless exhaust clamps and misc hardware that was not used.

I will be happy to provide more detail including possible sources, fabrication tips, etc. just let me know. We also have tons of pics if you need any specific views. Some can be seen on the first post in the Photobucket link.

Engine management / e36 M42 test engine

Simply a service for testing components to prove their viability. For someone who may not be able to verify a particular part works dynamically; especially ecu's.

Engine management / m42 tuning

« on: February 06, 2012, 04:29:56 PM »

We get 5psi @ approx. 2500RPM and typically don't shift at less than 2500. I am well aware of when open loop occurs. Plugs are clean, never a start failure in 20k mi. of driving including winter 2010-2011 in Upstate NY.

We understand the consequenses. In 20k mi. with this set-up there are none; and that's acceptable to us.

« on: February 06, 2012, 03:14:12 PM »

I have discovered the essential wires needed to run an M42 out of a 1993 e36 automatic while hanging on an engine hoist. It's not much, but may be of some help. What year is your M42 and do you have all sensors, ecu, etc?

Engine management / m42 tuning

« on: February 06, 2012, 03:05:58 PM »

WOT AFR is consistently 11.5:1 to 12.0:1 at 5psi,  2500 to 6000 RPM; verified by my son during the track sessions.

Is there any other open loop mode that we really care about other than WOT?
