Hey guys, I need a rear sway bar, either the MSP, MP3, or an aftermarket unit, for my MSP. Need brackets and possibly endlinks too, everything to hook it up. Thanks! -Matt

Simple question: are the pistons that MAM was selling about a year ago 8:1 CR or 8.5:1 CR? Thanks! -Matt

Hey yall, would somone mind measuring the resistance across a hot O2 sensor's sensor element (not the heater)? I'm trying to get my car to like me, and figure out how to do so. I would greatly appreciate it. Just disconnect the plug, and measure the resistance btwn the two wires that aren't...

FS: Yellow MSP 45k , $12.2k OBO (price dropped! ) Ladies and gents, today is a sad day. I have decided to sell my MSP. The car is absolutely wonderful, and has served me very, very well. It is simply time to move on to something I can drive in the snow. Thus, the entry of a WRX. The Car...

That's what I need. it obviously has to function. I would really appreciate the harness as well. Show me what you've got and I'll make you an offer! Later. -Mateo

Hello again, I have another problem as usual. To start out, if you don't know me, I'm not an idiot, I'm attempting to get my MSP back to stock with motor #3. It's running pretty well, all considering, but I have a single CEL: bank one too rich. it doesn't warm up properly, but cruises fine...

I've seen a few things recently involving confusion about FPR's, so I thought I'd share what I've picked up from working as a mechanic for a few years now. There are 5 main types of regulators. 1)non-adjustable static: does not see intake pressure, can't be adjusted by the user...

Ok, I have a CEL for O2 sensor #1 heater ciruit too high, meaning (from the service manual, protege5.ugly.net), that the PCM isn't seeing -12V at terminal it grounds to turn on the heater. that means the heater doesn't turn on, and I think it's causing my car to run like crap when it's cold...

ok, I have good reason to believe i fried by MSP ECU. now, my question is, are the msp and regular protege ECU's the same thing, just with different maps? If so, I can get one reflashed at mazda for 75 bucks. that'd be cool. Also, does anyone know for sure if the same fuel rail and...

Alright, I'm going to purchase a cruise control from a '98lx and attempt to make it work on the MSP. Has anyone tried to make this work yet, and what have their results been? Would it be worth it to get the cruise control from an '01-newer instead of a '98? -Mateo

Hey, I'm pretty sure other people have had this idea before, and I've heard of it being done before. I think it might be cool to put a rotart motor in an M1 miata. I have a Spec Miata, and am obviously used to driving it, and absolutely love it. Correct me if I'm wrong, but mazda made 2 RWD...

Hey, I'm going to attempt a cruise control install on my MSP. Does anyone have a cruise control system available from a P5 or sedan? I'd need everything. Thanks! -Mateo

Alright, i have good reason to believe my MAF isn't reading correctly. I'd like to buy someone's MAF, preferably an MSP, but realistically any one off of a 2.0L protege. Thanks! -Mateo

Ok, I've got a CEL for "P0090 Fuel Pressure Reg 1 Control Circuit". I had suspected something like this, but I wasn't sure. Now, what in the world does the car have to control fuel pressure? Is the regulator controlled by something electronic? Does anyone have any ideas on how to figure out...

Hi, I'm trying to work out some issues with my MSP, and I think they may be due to the MAF(maybe the MSP really did have a different MAF). Can anyone give me some readings on MAF output voltage at a few convenient RPM points? That would be very helpful. Muchas gracias! -Mateo

Alright, now I've got a CEL for too rich on sensor 1. I was pretty sure this was the case, but I wasn't sure. I'm wondering if the 255 lph fuel pump could be causing it?? I have the stock pump at home, but I don't see how this would really make a difference. -Mateo

Did the MSP come with a different MAF than the regular protege? I can't seem to find any info on it. -mateo

Alright, the megasquirt's out, since the protege will be used as a street car from now on. I'll put in in a miata (with an FS motor), so no worries, it'll be put to good use. However, in my quest to make the t3 setup run on stock management (shouldn't be hard), I've run into a snag. The car runs...

Hey yall, I've got an opportunity to go racing that I just can't pass up, and I need an SCCA racing license to do so. Plus I'll need one eventually anyways. I contacted the regional licensing representative, and here's what he told me: Now, I've heard from several people that the directors...

Ok, I'm noticing higher temperature readings than I expected after installing the temp gauge in the MSP. I'm getting around 210 when I'm cruising around and it's 70-80 degrees out. The fans doesn't even come on until around then either. The right fan only comes on if the A/C is on. My stock...
