Looks like I'm gonna try and put a restriction plate in.....my only question is what is the plate and where can I buy something like this?

 

Funy you bring that up.. I was just asking TTT about them

I was thinking of ordering Jegs part #176-3di03r Thats 3 disks for street use.. Im gonna use 2 sets of those and see how it goes.. Maybe i can just run a 3"tail section without a muffler...

 

Pressurized, you can make one your self. Or get a machine shop to make them. Use the gasket as a template.

I had some made out of 14 gauge stainless steel.

The best thing to do to control creep is to port the wastegate .

How about this part from SummitRacing.com....part FLO-R3025 ....I wonder if that would work.....

SAINT, how exactly do you port a wategate, I would probably have to do it myself, the only rotary shop is 5hours away.

 

No!

Thats totally different to the one im talking about.. check the one im talking about out!

 

Want2Race,

I guess that would work, but it looks pretty permanent if you weld it in place, or rivet it there. What if you eventually port the wastegates?

A restrictor plate is temporary, start with a small ID and go larger.

And much cheaper. You could get a machine shop to make you 10 for the price of the piece from Jegs.

Porting the wastegate is a matter of taking a grinder and grinding the wastegate orifice larger, but not beyond the edge of the flapper door that blocks it off. You can also smooth out a lot of the sharp edges of the turbo housing. It took about 15-20 minutes of grinding to get it done.

I am not doing this for backpressure... I have an oversided wastegate.. I intend to do this because it does not reduce power but it reduces noise!So if i can run quiter I would be happy.. Im not into a loud exhaust @ all...

 

Ah I see. Well it should work then. I installed an XR-1 for noise, but it is quite bit more expensive than the piece from Jegs, and as permanent. My bad.

Let me know if it works.

apex has one! its call a "exhaust valve control" i think. i order one like a two weeks ago, i should be getting it any time now.
it cost me $220.00 it comes with cable so u can open or close it

 

ek9220ps: is there an EVC specifically for the RX7? Where did you order it from?
Do you have to get it welded to a pipe and use it as a flange? Where will you be running the cable?

Let us know how it works. A very interesting idea.

Mike

 

I also saw that product on the apex site...has anyone used it? I'd like to use it for noise reduction when I go mp...concerned if the thing will melt or not...if it will...do you think ceramic coating would help?

 

ek9220ps,

Could you tell us where you found it? I wanted to do this but I couldn't find one for the FD. Or did you just buy one and your trying to make if work with th FD?

Please let us know.

 

the shop is call VIS in the phone # is 626-573-8383. i think its a universal plate. the biggest size apex make is 3"

 

so is this an ECV a kit specifically for the FD?
