It's a cosmo 13B-RE with a pretty nice street port on it. The motor was built by Andre from Mazda Specialist here in Miaimi Fl.

Stock RE intake.

Yes, with a custom made intake. The RB intake does not fit onto the RE block.

Nice! Looks like I need ~100hp to catch up to you! I wish I dynoed with my 13psi spring in... I'd still be 60hp short though I'd guess.
You can see how the your port job helps out the flow in a big way when comparing your dyno sheet and mine. Your power just keeps going and going while I'm done at ~7k.
Do you have a link to some underhood shots?

Nice work !

Thanks Cam, but I can't really take any credit for it. It has been all Chris. - He's been trying to make sense of my mess. I was wondering where you have been hiding!

I have a new fan, new catch can, and other things since these pics.

I see you still have the stock cosmo TPS, how's it been working for you? Mine didn't work for ****. I suppose it's not a big issue if you're not running a BAC valve. Up here in MN it's nice to be able to reach in on a 30 deg day and fire the car off and let it run ~1200rpm till it get's warm.

The IC plumbing looks like it was fun to do! I still like how your turbo is a bit higher up, makes for a nice sloping turbo drain. Also, you can point the outlet of compressor housing down for a cleaner look.

How do you like those MSD coils? Oh wait.. you were troubleshooting a ign breakup problem. I'll ask that question later when you get it figured out. For some reason with my stock FC leading coil I'll wear a #1 plug out faster than the #2. I should swap plug wires and see if it follows.

Are you to the point yet where you can run closed loop? I find I get ~18-19mpg with mine working going to work and back (some stop and go with a little wheel spin here and there ).

[QUOTE=setzep]I see you still have the stock cosmo TPS, how's it been working for you?
It's working perfect.

The BAC valve is hooked up.

How do you like those MSD coils? Oh wait.. you were troubleshooting a ign breakup problem. I'll ask that question later when you get it figured out.
It was a combination of two things. The first time we went to the dyno the datalog was showing rpm scatter due to a weak reluctor in the CAS. The second time was due to the rpm pickup for the dyno being too close to the lead and trail ign wires which resulted in crossfiring. Even with the shift light disconnected the noise would activate the light at low rpms and was causing the ignition/spark to blow out.

Are you to the point yet where you can run closed loop?
No closed loop. The car is always set for kill so the lead in the C-16 destroys the O2's quite easily.
