Difference between MP3 and MP5

[chuyler1]

I'm curious,

Aside from the obvious, what are the differences between the two cars? eg: what gives the MP3 the extra 10hp?

 

[MP3skaterNC]

the mp3 has a better suspension, sound system, and advanced timing gives us the extra 10hp along with a better exhaust.

Personally I can do without the kenwood sound system. Thanks.

I'm assuming the exhaust is available, but is it possible to time an MP5 to get the 10HP gain?

Switch ECU's.

 

[JrTekSilverP5]

and thats all u gotta do.... switch ecu's??? im sure theres more then that

 

[alexlitov]

No.
You just switch CPUs, but you also have to get some suspension parts from MP3 to have all of it. You need a sqeak to have that 10 HP

Just get an intake and a full catback 2.25" exhuast and your already ahead of the MP3. Also the MP3 does not have some sensors tat the P5 does so the ECus aren't an exact swap but it can be down.

THe MP3 has a better suspension but you don't want the clunk and squeeks so stick to some good struts and lowing springs

 

[chuyler1]

Well I was considering an exhaust/intake upgrade but the consensus seems to be that I won't gain much more than 7-8HP. Plus I don't want my car to sound ricy, if you know what I mean.

I hear you on the suspension though, my MP5 is tight enough for me.

You won't sound ricey if you get the right exhaust. I have a Thermal and it sounds good. It has a lower tone than what I've heard before. The intake has a pretty cool sound to it to but it doesn't draw too much attention to itself. Your right, you probably will only see a 10HP increase but this figure is probably at the wheels. Basically, an MP5 with a good 2.25 exhaust and a CAI will be ahead of an MP3.

i think the mp3 ecu is pretty expensive too!

Difference?

The only differences between my car and an MP3 is 10hp (which is made up by intake and exhaust) and I have a 5th door on the back. I lucked out I guess. Dealer show cars cost more but they are worth it.

 

[chuyler1]

So you don't get an extra drone from your exhaust on the highway? I don't mind a little noise during acceleration, but I can't stand cars that have this drone coming from the tail pipe at 75mph.

There is no need to buy an MP3 ECu but it would be around $1200 if you did. Its the same computer just a different program.

And the specially tuned suspension (sway bars, struts, springs), the diffrent ecu, built in MP3 player, shorter shifter.....

BTW, the 10 HP is from the ECU and the exhaust. You'd be luvky to get 10 from intake and exhaust.

 

[1sty]

most of the the 10 HP is the retuned computer which is simply 3 degrees of advanced timing. See if a dealer can flash your ECU with the MP3s program.

 

[chuyler1]

Thanks, i don't need the suspension, mp3 player, or short shift kit...

I just want a gauranteed 10hp gain if I am going to spend money on mods. Because it seems that just an intake and exhaust won't do it.

Does the MP3 take higher octane gas then?

 

[KYREDP5]

Yes it requires higher octane. You'd be better off going with intake, exhaust, then cams if you want gaureneed 10 hp. That'd end up being a little more than 10 hp.

 

[sundevilMP5]

switching out the ecu is definitely not worth it...it costs too much and the performance gain isn't even near 10hp...flyin miata did some tests with this...they tested a stock mp3 then switched to the P5 ecu...check out the minimal loss between the two

The thing is it's crank-shaft hp, not at the wheels. So if an exhaust and intake dyno shows a gain of 10hp thats probably 15-17hp at the crank.
