Besides not working with a stock ecu, those intakes are really all high rpm anyways.

That intake manifold has huge runners and is really only good for top end power so I believe it.

I've been running only synthetic since the late 90's and I have never removed the OMP or premixed. I've owned 5 RX-7's and have never had a single engine go out.

Have you tested this or are you guessing based on what you are seeing in regards to chamber volume decreasing while the ports are still partly open? The reason that I ask is because when those ports...

The S4 na diff will be a direct fit. The S5 TII limited slip is a viscous style which I don't personally like. They are harder to find and as mentioned would need the axles and a new driveshaft as...

I think the idea certainly holds merit. It's awesome that you decided to think out of the box. It's a creative solution. I'm not sure that the patent will be granted but it would be really cool if it...

I would generally say no as it's going to be the electrical generator for an electric motor but it still needs to meet emissions standards. I have no idea what rpm they intend to run it at, or if...

Only if you can find a 100% bone stock TII. Good luck with that. Literally every single TII that has been modded in any way should be avoided like the plague. Sad to say but the average rotary owner...

I'm a little late to the party but when I had an S4 for all those years, all I wanted was an S5. Now that I've got an S5, I wish I had the S4 again. The intake is certainly simpler. For the mild...

The exhaust size actually isn't a restriction. It's a misconception that the exhaust needs to be large. A larger exhaust port does affect power a bit but what it really does is move the max usable...

Your power curve is beautiful. Nice and smooth with flat torque. 203 seems a bit low for a bridgeport but I don't know how large your bridge is so maybe it is, maybe it isn't. For a street car it...

Do you still have the double throttle plates on the throttle body? When they stop working, they default closed. I had this issue about 20 years ago and just about lost my mind trying to figure it out.
