Question ACV block off plate - searched

Is the block off plate for the TII the same as for the N/A? I need to bypass my ACV to clean up my CO at idle, and want to do it right.

I want to say both the flange and bolt holes are different. Been awhile since I messed with an NA one though.

k2rd has an acv plate for turbos, and egr plate for all 13b's. The egr and acv are different components. I'm sure you know that, liquid. What is different about the acv on the turbo vs the n/a.

*posted the last part too soon.* lesson, be a little more patient.

I'm very aware of that fact. My engine is out of my car, dissassembled, and getting work done to it; the work is being done by myself. I'm no slouch when it comes to N/A RX-7's.

He asked if they were the same, not WHY they arn't the same. Simple question, simple answer. No, they're not the same. Block-off plates for both can be purchased thru www.k2rd.com

Thank you, drive thru.

Sorry to have offended you. I said I was sure you know that because of your very knowledgeable posts in the past.

Actually, I asked if they were the same. Then, when you said no, I asked what was different. Both questions were mine.

I'll look again at k2rd.com, but I could only find the turbo plate. Do I need to tell them in some note section that I need the N/A plate?

First, you had me fooled. I've always regarded your posts as informative. Now, enough *** kissing.

Second, I guess I clicked every link but one. It's always in the las place you look cuz you always stop looking when you find it. Thanks, it's on order.

Make your own. A drill, a hacksaw, a drill bit. I made one out of the bottom of a old vcr cover plate. Not more than .030 thick. Add some rtv for a gasket and your done. Cost? Squat. Time. Thrity minutes. Theres no real pressure behind the acv. Just make sure it has no air leaks. Leave the check valve in place. Put some vaseline on the top of it so the rtv does not stick to it in case you want to use it again someday.


Bolt patterns are different and the shape is different. Don't waste your time and money buying one. Make one and be thru today.

The part in the original question about bypassing the acv to clean up your CO's somehow does not ring true. Whatever.

The catalytic converter on every car ever built uses retained exhaust heat to ignite and burn unburnt fuel and fuel bi-products. This only happens when there is sufficient oxygen for these to react with. When an acv ages, the diaphram tends to harden. This can reduce the amount of air flowing to the cat from the air pump, which in turn prevents the cat from doing its job properly. It does ring true. By ensuring that air is being pumped to the cat at idle, I should see a reduction in CO emissions because there will be plenty of oxygen for the unburned fuel to react with. For those who might say I am prone to melt my cat, this will only happen if I am running way, way, way to rich at engine speeds above idle. It requires a great deal of unburned fuel to increase temperatures in a cat to the point of melting it. My emissions are clean as whistle above idle, so I know I'm not running rich.

FYI the ACV pumps air to the cat ONLY in 5th gear crusing. under 4000rpm or so in other gears it goes to the exhuast manifold. over that gets dumped into the air.

if you are planing on putting a line straight from the airpump to the cat. it'll melt in no time.
