Fiid's Project Progress Thead., The Legend of Narparu Options

I am considering a variation on this engine - probably from a single turbo WRX. I have a Haltech E6K which will have no problem running the engine - I have even downloaded a WRX base map for it. Talking with guys over at NASIOC forums they recommend either the 2.0 or 2.2 turbo engines.

MegaSquirt can certainly handle the fuel side of the engine. I'm not sure about the ignition side of it. The problem is driving all the coils. Currently, it is working with 1 coil driver and 1 coil with sparkplug wires or, with the Ford EDIS system which is wasted spark and uses coil packs and sparkplug wires. To run the coil on plug systems you will need 4 coil drivers and a cam sensor to determine which cylinder is to fire. Unless you can figure out how to tap the stock ignition system prior to the cam position sensor you will probably have to give up the coil on plug system. That's way more than I'm capable of.

I've been trying to figure a way to put COP on my car but I can"t get past the cam timing issue. I've got 8 Ford coils from a Crown Vic siting on my bench and they'll probably sit there for a while until someone with some intelligence figures out how to use Mega------- to run COP.

I am leaning more and more towards abandoning Coil-On-Plug and doing the EDIS thing. There is a clear path to getting that to actually work, which is very entising. I did wonder if you could put the two coil on plug coils in parallel and run them wasted spark - is that possible? Or unwise?

The Tomtek controller claims to do coil on plug, but it's not very developed yet. That is another possibility. If i get boards made - is there any other interest in messing with that?

EDIS is looking pretty nice right about now.

What not just get the MAF sensor you need and run it in stock configuration at least until you make sure everything works?

If it has coil on plug stock then it should have all the sensors it needs to make coil on plug work with aftermarket parts too. (?)

Firstly, I don't know which MAF sensor. I could track one down, but this vehicle is rather obscure, so it may be easy or tricky. I have a feeling I need a specific type which may not be available in the US, since there have only been a few Subaru Turbos here to date, and Subaru switched from MAF to MAP before the new ones came out.

Next up, I have the ECU. I have the gred box with about 80 wires hanging out of it. Most of therm are different colors. They are different thicknesses. Some of them are bundled in groups of 3 or so. Others are not. I do actually have a wiring diagram now. It is 66 pages.

The wiring diagram makes this possible, instead of impossible. Having said that, wiring up a tomtek or a megasquirt is a breeze, plus you can dial it into a PC to figure out what the problems are. None of these things are possible with the stock system., Plus I will have different exhausts/intakes, etc, which might freak out the stock computer.

The Haltech is attractive, but not cheap by any means. Not sure if I want to go that way or not yet.

Fid,
I would lean towards getting the stock configuration running as it came from the factory. Leave the cat in place to restrict flow to the turbo. Keep the stock computers for fuel and spark. You know it will work and get you the 275 you expect. Rengineering so many aspects at a time will be tough to tune. MAFs aren't all that special. Talk to your scooby friends and see what they suggest.

You're right about the wastegate and BOV BTW. But, you knew that... (IMG:style_emoticons/default/agree.gif)

Why is it so hard for people to remove wiring harnesses correctly? That sucks. I feel your pain. (IMG:style_emoticons/default/sad.gif) It is a shame because stock ECU would be pretty much plug and play.

A friend of mine bought a whole 93 Firebird because he wanted the LT1 AND the computer AND the wiring harness, and it was easier to take them off himself than deal with whoever chopped up the wiring on most of the used engines around.

"I have the gred box with about 80 wires hanging out of it. Most of therm are different colors..."

Ooops I missed that part.
Nevermind... (in a high annoying voice.)

I actually don't have the cats - or even the flanges for the turbos.

Here is the engine computer as I have it. The wiring harness for the engine looks about the same (i.e - chopped before the plug).

The IMI starter arrived today. It works nicely, and fits in the gap next to the turbo.

Good call Brad! (IMG:style_emoticons/default/smilie_pokal.gif)

I am looking at an engine computer called "tomtek" that will handle coil on plug ignition and is also capable of driving stepper motor idle controls (like the subaru has). It will work in conjuction with the megasquirt. The megasquirt also has some auxialliary outputs (like the idle solenoid) that I will be able to use for boost control and turbo sequencing.

You might say I know my ass from a whole in the ground... just suck at shipping.

For a nasty street car this is appealing with the single turbo 2.0 liter...
Has any one looked to see how hard using their transmission would be and or if it measures up. Just saw a sportsracer(sakermotorsports.com) using a wrx motor amidships.

[fiid]

This will be a nastry street car too :-).

Today's winnings from Pic-N-Pull include 2 Ford EDIS Modules, a coilpack, and a harmonic balancer with a 36-1 trigger wheel :-).

This should take car of the ignition side of it.

I have ordered another megasquirt to go with it, so I will be doing the Megasquirt-n-Edis project shortly.

More details to follow.

I'm sure it is but I was going for a "simpiler" conversion for the more handicaped fabricators among us, ME.

The single turbo with its wire harness and computer or aftermarket computers , the exhaust doesnt look too bad , water cooled been done, adapter plate been done,
torque doesnt look too bad for the 901, heating and air does'nt even look too bad and the engine and or entire drivetrain looks very reasonable.....Back to the original question, Has anyone looked at the subaru tranny as a fit??? Custom mounts and axles .??? I saw a midengine subaru race car and the layout is very simular to our cars. Advantages to a modern gear box. The whole thing can be purchased for $4k..

My goal is the daily driver with 225 plus with heat/air and could drive anywere...

Pulled the 1.7 engine out today.....
