What psi can i go!

[Crazyk20201]

so far my MSP is completely stock, i was thinking of getting a BOV and IC pipes first. how much better is a 2.5" turbo back aftermarket than the stock MSP package exhaust?

Also b4 i do anything i am getting the boost guage and MBC, what is the factory boost setting and how much can i squeeze out of the stock system. the T-25 is also the same turbo the 2g eclipse has and i know those guys set their boost to 15-17 psi!

honestly, i would suggest doing other mods before uppin' your boost. Although with colder spark plugs you could probably "safely" run 8-9 with no problems. But then again, I can't promise anything

btw, i think the stock boost level is 6.5 (psi)

well is there a guide anywhere on what mods to do and in what order? that would be extremely helpful!

BOV and IC pipes are basically no net gain. Why do those first? Largest gains for the money would be going catless with a 2.5 or 3 inch exhaust. It all depends on your goals though so good luck. I would also agree with building the car with bolt ons first (if that's your plan) before the mbc.

you can run 15 psi.... Blow up the engine and that would be 1 less car on the market and raise my car's value.... but really get midpipe and exhaust first..

It really depends upon your goals, there is no "one right way" really. There are better ways than others but each modification should make sense with your goals IMO.

If you think the value of a protege is ever going to go up you are crazy. It's an econobox not a rare handcrafted italian sports car or something.

You can forget about running 15-17 PSI unless youare DiscreetSpeed and have a whack of supporting mods.
Stock boost is 6.9 PSI.
Adding the boost gauge is fine, the MBC should come later.
Look at exhaust or at least midpipe. The stocker is restrictive with 2 cats.
You can get hardpipes that come with a CAI.
Colder plugs, and then up the boost to about 10-12 psi max.
You will probably need a fuel cut defender as well becuase you're going to hit cut for sure.

Most exhaust systems will yield 5 hp at best. But they look better and flow better than stock. I like the Greddy SP2 system.

The stock boost is 6.9 psi. You will not be able to run 15-17 psi in stock trim. The t25 could handle, but the PCM will not allow it due to its tuning.

Get your guage installed and see what you are boosting. Then you can start to tinker with your boost. Caution goes a long way. Our cars are just not set up to run 15 psi of boost in stock or near stock trim. It runs 100% better at 10 psi of boost.

get the colder plugs, fmic, exhaust and then get an Ebc. you really don't want to spike that badly. if you're looking for a list of mods (in an order) to do to your car do a search within the MSP performance section and the general performance section (you'll prolly get the best info in the general section).

btw, boosting to match the 2g eclipses will generally surpass the efficiency of the turbo and you'd be much better off trying to find that point or upgrading the turbo. IMO.

What? Maybe a catback but anything that's 2.5 or bigger that removes the cats is more like 13whp or better. Sorry, I'm being difficult today.

Discreet is running 15 psi daily and his engine is ok so.... (screwy)

don't take this as an insult, but it sounds like you're pretty new to the car scene. this being the case, i suggest you stay away from a boost controller, because unlike the DSM's the MSP's can't handle a lot of boost stock.

start with bolt-ons such as: intake, exhaust, fmic and then start thinking about boosting higher. Catless DP > 10psi on an otherwise stock MSP.

yea sorry i am very new to Mazda's, i am just going off what my friend knows about his DSM, he knew they were the same turbo and wasn't sure about mazda speed packages, he thought the exhaust was a full 2.5", so basically the MSP package is worthless if you start modding, you have to rip it all off anyway! ok thanks guys, i was just curious as to how different the DSM and MSP were, i will search frantically to expand my mazda knowledge!

i hear ya, 2 of my friends have 2nd gen DSM's and run 15psi daily w/ just an intake and BOV. my one friend ran 17psi for a while and in december he blew his turbo.

unlike the DSM's the MSP's T25R is ball bearing, thus the R. The stock MSP piping is quite restrictive with 2 cats and various small diameters. You can go custom if you want and get a turboback exhaust that uses the stock muffler though. the MSP's and DSM's both come with that crappy lil sidemount IC, so I'm sure you're aware of the heatsoak problem this creates on both cars.

the tuning is what holds you back from upping the boost like a DSM. once you've got the bolt-ons covered, you'll be amazed with how much power you can pull out of your little turbo with proper fuel/spark control.

goodluck on the searching

It's not worthless at all. Not many cars handle like it. And with bolt-ons it becomes so fun to drive it's impossible to beat for the price IMO

 

[TooleBox]

each MSP is completely different... some can boost 12+ psi on stock fuel and be fine... others (like mine) run perfectly stoich at 7-7.5 psi...

the only way to know what you can do on YOUR car is to take it to a dyno and run your boost changes on a wideband A/F meter

you can see my dyno and A/F map here:

23psi of boost on 87 octane.. Works for me.


Dude for the love of god, read the god damn forums and do 5 seconds of searching before you make a new thread.

kthx

its stickied at the top of the MSP forum, and i linked it in one of your other threads. :mad:

DSM's also have 450cc injectors stock, and blocks that handle 500hp with upgraded head bolts..
Totally different engine.
TOTALLY.
