ok that was weired

 

Right now... just that, the S4 header and no cats.

After breaking in the engine, I'll go with a fully custom exhaust.

2" OD primaries, collected, and 3" from the collector to the back.

 

Wow what a different build! a exhaust might be a good idea, no emissions made my n/a would shoot flames sometimes. bad news if it shoots it under your car.
I like how rare our cars are getting. I never see them anymore.

 

heh Initial D fan?
I think i stayed up three days straight watching the whole series.

Now every time I look at my FC I wish i was downhill racing. heh,
But awesome build
Keep up the good work.

 

Some updates!

My precious.

Going wing-less!





Some more detailed pics of the DLIDFIS setup



2x MSD Blaster 2 coils for Leading



1x OEM coil for Trailing



3x GM HEI ignition modules, with a big heat sink

 

With only a couple of kilometers since the Rebuild it still runs terrible, hehehe -- idleing at about 1400rpm

I'm in love, hehehe

Glowing exhaust section...



Bye bye old fat HID kit



Hi new, slim one



... and new gunmetal shift-****



Oil catch can installed, where the ABS pump and and Cruise Control used to be





... and that's it for now

 

Oops, disregard.

 

IS it running right yet? I've never had a rebuild sound like that when I started it....

 

Check out the videos I posted, it is running.

 

Sorry, but it sounds awful. Your exhaust should NOT be glowing. Something is VERY wrong.

 

Seriously, how would you expect it to sound?

It's a just rebuilt, NA 13B with a huge exhaust port, and bits and pieces of other rotary cars... DLIDFIS ignition, an archaic ECU, thermal reactor/heat exchanger exhaust with a S4 NA header... no cats...

That exhaust section glowing is basically because the "tune" is **** at the moment

 

Something is very wrong. It shouldn't be making the exhaust glow.

You deleted the exhaust diffusers, right? Doing that kills the flow through the exhaust port which may be partially why it sounds so bad, but I still think something else is wrong. It sounds very bad.

 

Timing is more than likely way off which is a ez fix. If it we're my car woulda kept stock coils and tossed a msd box on the leading.

 

When you say the stock coils, you refer to the FC coils? Remember... my car didn't even come out of the factory with those coils, not even a CAS. This car came with an electronic distributor and "those" coils... FB-style ignition.

DLIDFIS sounded like the best way to go, before getting a standalone EMS.

Regarding timing... the thing is that setting it right isn't easy with the car idleing at about 1400rpm... we can get it down to about 1000rpm but it isn't very stable at the moment.

Pineapple Racing's Rob Golden recommended to set Leading to 0° with this type of intake/exhaust porting.

I'm also open to any other tips or feedback you guys might want to share

 

Set the motor at tdc, zero out ur distributor and go from there. Had same problem when I stabbed my cas a tooth or 2 off.

 

I'm looking forward to seeing this thing in full operation. Great build, dude! Keep it up.

 

Thanks a lot for the tip. I'll look into that as soon as possible!

 

Yeah, it is running like it is 180degress out of time or something.

My point was I have rebuilt motors and they don't run that poorly when started, It was limping around and seems that it must be detonating in the exhaust for it to be that red hot.

 

Having been around rotaries for the past 8 years, hearing dozens upon dozens of engines, some stock, some heavily modified and everything in between, I never heard one that sounded like yours. I've done the "walk of shame" driving home with a blown motor, it didn't sound as bad. I am sorry you felt insulted, but your engine sounds terrible. Something is wrong.

 

Timing WAY off can cause the exhaust to get that hot and glow. You said you were playing with the "lean/rich pot" are you referring to the screw adjustment of the vaf or does your car also have a standard s4 variable resistor? I ask because i have no idea what is standard to that ecu.

 

No one knows what is standard on this ECU

Yes, I am talking about the variable resistor.

-- btw, if you guys can help me out with this I would be impossibly happy

 

Have you checked compression since the rebuild? My very large street port(intake/exhaust) idles like stock. Your car should absolutely NOT run the way it does, it sounds terrible.

 

checking timing is key, but also make sure your coils are firing, especially in order. Don't want any backwards or upside down.

 

What kind of numbers should I expect from a freshly rebuilt engine with less than 40 miles?

 

By the way... let's not forget this engine came with a thermal reactor... this means that stock, it ran even richer than a S4 NA engine.
