Pm'd about after market smic.

I found a cheap and easy way to reduce exhaust noise if you have a silencer. You take the silencer out and wrap the small end (the end that goes further into the exhaust) with home insulation. Once that is done you wrap some flexible metal wire around the insulation to keep it in place and you...

The previous owner of my mazdaspeed protege installed the MFactory 4.687 Final Drive Ring and Pinion gears. I know that because I used the mfactory transmission calculator along with my observations from driving the car and the values match up with stock transmission ratios mated to a 4.687...

Yeah i paid a bit extra for the part, but i am OK with that because my car is working just fine again.

I just found it on Callaways website. http://shop.callawaycars.com/O-Ring-Turbo-Oil-Drain-Fitting-MSP10015002.htm I think ill order it from there instead.

I found a leak between the turbo and oil return pipe, so i am going to change the o ring in there and see if that fixes it.

When I boost with my car lately it will perform just fine, but i can smell something burning. When i stop and open the hood i find that there is smoke coming off of the turbo. Anyone have any thoughts?

Mine came installed on the car when i bought it.

Is the CUSTOMMSP side mount intercooler still for sale?

What about replacing the muffler with a twin loop style muffler? I hear those are supposed to be quieter.

Do you have a suggestion as to a good quieter muffler to use?

So I have the Vibrant exhaust system on my mazdaspeed protege and it is fine in the city, but its too loud on the highway even with the silencer in. What can i do to fix this?

So i haven't tested this myself, but there seems to be dyno proof that using a catback can yeild gains. http://www.importtuner.com/powerpages/impp_1006_2003_mazdaspeed_protege_power_pages/

So i stumbled upon this performance chip that touts gains from just plugging it in, but i'm rather dubious as to the validity of these claims. So i am asking you guys what you think / have heard about it or things like it. If its not a lie then it would be a very cost effective power boost...

I got mine in july of 2011 with 45k miles and it just hit 52k recently.

Does anyone know how many MazdaSpeed Proteges are left on the the roads of the origional 5K or so? If not is there a way to find out?

I was under the impression that the t25 was small enough that it has trouble keeping up with the demand created by higher rpms. Is this incorrect? Also i may have done a bad job of explaining my question. I believe what most people call it is a spike in boost that you get when you first go...

Anyone?

When people say they boost 10 psi does that mean that it peaks at 10 psi and then tapers off as the revs get higher, or do they mean 10 psi at close to redline say 5500 or so?

I was actually just thinking about this today and i'm totally interested.
