I've just converted over from Honda's and a couple of month's ago I got a Nitrous Works wet kit (25 to 75 shot) never installed it and wanted to put it on my PR5. So i guess my question is can this be done safely and will it make good HP for this car and how much can these types of motors hold?

Up to 50 for short intervals should be fine.

But if you go to RACING STORIES section, you can read a story of one individual who messed up his engine by spraying too frequently without giving it a break to cool down. He was using a 50 shot I think.

my 2 cents: Keep your car clean. Don't get it hooked on crack. If your car is new, the warranty lasts for 3 years. If you save up $150/month for three years, you'll save up enough to buy a turbo kit from Tripoint Engineering ($3800) and have money to get it installed at a shop ($1000).

sell your kit and instead of filling up N2O, save up money for a turbo kit like dynamho said

But people run 55 shots with no problems

my thing is with the turbo is it really worth spending 4k on something when i've spent $250 on the nos and its the same HP and the turbo is putting strain on the motor all the time.

atticus: what you are saying makes some sense about the turbo putting constant strain on you motor but, from ive been told about from many people is that a good rule for nitrous is that every time you use your nitrous the strain is like adding and additional 50-100 miles of wear to your engine depending on what size jets you are using. im kinda in the same situation you are in i think. i cant really decide on a turbo kit or awr headers and a ZEX kit. ohh also if you dont know much about your engine and are planning on installing your nitrous your self. before you spray it take it to a shop and have them double check your work for any problems. id hate to see/hear about another mazda blown up due to improper install.

Those are wise words Vibrantvivid.

Regarding turbo's full-time motor strain concern: When you decide to go turbo, I believe you can also get a boost controller to manage wastegate settings. Turbomeisters, please correct me if I'm wrong on the previous point.

By controlling the wastegate, I think you can vary the amount of boost you want with max boost being what your turbo is set up for.

Furthermore, saving up for a turbo has indirect benefits. As time passes, more aftermarket support will be given to the Protege platform. Protege's, because of MP3's success and the sporty buyer demographic of Protege 5's, are getting more glances from aftermarket companies. This means that more likely than not, we'll see performance parts coming down the line for us.

Who knows, THEN, you may decide that the money you're saving for a turbo is better used for other performance parts.

2003 Mazdaspeed Protege is supposed to have 170HP.
Tripoint turbo on an MP3 dynoed at around 210HP. That's a 40HP difference, almost a bottle of 50 shot crack.

I believe the Mazdaspeed Protege will surely exceed 20 grand in price. You can get a Protege ES nowadays for about 14 grand. Adding the tripoint turbo will bring it up to 19 grand and you still have more than a grand left over to buy handling parts to give Mazdaspeed Protege a hard time.

I think saving up for a turbo is a smart thing to do. The Protege's better powerband with the tripoint will make even Civic type-R's sweat!

PS: Also, once you pay off your car (if you got financing), you can use your car as collateral and borrow money to buy the turbo!

well i thought about the turbo but not alot of people know about them from what i hear the tripoint isnt very good but im new to this.

Sal's "J"

I'm not boosting yet, however I've got two buddies w/ Civic turbo's one @ 5.5pounds and the other @ 15pounds of boost. Just riding w/ them you are not always at boost which was my misconception about turbo's. With just regular driving neither one of them will boost at all and that's shifting at 3500-4000 RPM's. Then on the highway, even going 70MPH, they are not boosting, but if they put a load(i.e. speeding up to pass) w/o even downshifting, just depressing the accelator-then they start to boost, but as soon as they revert back to normal driving-No boost.
So I have changed my thoughts regarding turbo's and their practicallity w/ daily driving. So unless you are boost happy, you can drive all day long w/o boosting at all.
Now of course it all depends on how you set your turbo up will depend on how soon you boost and how much, but I think that turbo is a good, reliable way to get extra HP out of our 4cyl and still have good gas mileage.

dynamho

That's real good info Sal. Real life experiences are the best.

So it is true when they say, "there's no replacement for displacement."

Based on your story, it seems like unless you're at WOT (wide-open throttle), the car's horspower will actually decrease because most people retard ignition timing when boosting for fear of detonation. Perhaps the Honda you were talking about was set up to spool at a high RPM? I should think that small turbos with 5.5 psi boost will spool up relatively quickly, probably starting from 2000RPM?


BTW, Atticus, I'd like to read some negative comments, if you can direct me to them, about the Tripoint turbo because I haven't come across one yet. That would make all of us wiser before commiting.

everyone is just saying that the begi is better i dont know cuase i really dont know the diff between the two
