horsepower???????

[LAZERBLU2003.5]

Hey, maybe some of you guys, or girls can help me out....... what is the maximum horsepower can we get out of or engines with out changing the internals and what is the maximum boost you can run with stock internals before shit goes wrong????

the rods will hold 230-250 well tuned hp with no issues. Beyond that, its a toss up, and comes down to tuning...

Reliably for a decent time frame, I'd wage 220 crank horse power. As for raising the boost, I'd stay at 9 PSI or less.

is it just that our engines can't handle the boost like the sti (14.5) and the evo (19.5), so I've heard???

Kind of. Let me do this in bullit form

- The MSP engine was NEVER intended to be turboed. It was not designed for it.
- The MSP went through so rather qucik and dirty computer setup that doesn't account for raised boost at all.
- The MSP, if properly tuned, can handle 12 PSI day in and day out but that tuning comes via engine management systems and not a simple or inexpensive solution.
- The factory computer must be removed form controlling the MAF, fuel injectors and the spark plugs otherwise the car will run as if it was never altered and it will try to compensate for the weird data it logs. This is a big hole in the engine.
- The EVO and STi have had there problems of late too. Too many of there buyers assumed they could just modify the car with exhuasts and bigger turbos, larger injectors, ect and it would be fine. However todays cars are to stricky programmed and although my STI in stock form can handle 14 pSI no problem, if it got 18 PSi for to long with nothing to compensate for it, the car would be just as broken. Same for the evo.
- All 3 cars where programmed to operate to a certain boost level and no higher. Any tampering with one sstem must be matched by tuning ofr it in the rest. As a good example of this, as STI owners are learning we can't eve install a turbo back exhuast without risking the motors. Our wastegates are too small and the car will over boost and nuke itslef.

I wonder why Mazda did not follow suit, i.e. SRT-4, STI, EVO etc... and use stronger parts and kick boost way up like all the other guys? (this is just a question, from a MSP-newbie , who's doesnt know anything about cars). It seems they got the speed and we got the handling (from what I am assuming).

I wish there was a sticky for MSP-newbies that explained what the limits of our engines are and what are all the differnt modifications, along with a build map i.e. you choose a mod and it shows what other mods will work or will be needed and what other mods will not work. Then provide links for purchase along with a price list.

And yes, let me guess this has been discussed a billion times already. Sorry, I don't feel like spending 3 yr's of reading to find out what I need (and still not understand what I just read). I apologize in advance for any repost of an old question and thank those in advance for any positive comments.

Simple, becuase the EVO, STi adn SRT/4 have been being designed for years. The evo engine is a japanese one and is nothing new. The STi although useing a new engine has been on the drawing boards for some time and in all case these cars were specificly designed to sustain boost. The MSP on the other hand was a quick attemp to answer the complaint that all reviews had of the MP3 that it lacked power. It was ment to run with the focus SVT and Sentra V-spec, not an SRT/4. The MSp had one year to get into port and that didn't leave time for a radical engine overhual and Mazda did not have a boost friendly engine that would bolt into the currect protege.

The problem is no mod is concrete in its results. Some MSPs have boosted to only 9 PSi and met there death, others go daily at 12 PSi and are fine. Teh climate, altidude, available gas, and even the specific MSP itself play a huge part.

Thank you very much for the post MP3/NH, do you have any suggestions for a mod or series of mods that are pocket book & non-mechanic, newbie friendly (does that even exist (dunno) ) . For example, my real life brother is Yashooa on this board and he has a MSP with a booste guage & MBC, but it seems other than those 2 items there are really no other easy & cheap mod out there.( there I go wishing again (drunk) )

any advice would be helpful, thank you in advance for you're assistance...

Thanks 1st. That summary helped me understand a lot of the info I've been reading here over the last weeks. Been hoping someone would do that.
