N/A or Turbo

[Concept P5]

The long debate....... now i know CHDESIGNS has pretty much most of the N/A mods u can get.
and there are a few boosted members with different setups.
which is the one that you would choose? cuz i am still in the air about all this.... so help me out guys: any HP estimates.

Route to choose for N/A:
10.7:1 comp pistons
port polsih engine( whole dam thing.... since pistons going in)
Camshafts
S-AFC
bore throttle body
Headers
hi flow cat
muffler (piping)
tripoint camgears
fuel regs and injectors
Injen CAI
AEM engine management
(NOTE I HAVE SOEM OF THESE.. such as camshafts CAI muffler and cat)

TURBO:
Spoolin Manifold
16g turbo
intercooler (spearco:if it fits.... if not starion)
HKS BOV
HKS TT
HKS BC
HKS WG
VORTECH 10:1 FMU
and of course exahsut......

also any benefits of each...... turbo is BOv.... lol love it.... and teh kcik it gives when it spools

If you want good power without spending a fortune go turbo. I spent over 5K in my engine and didn't see s*** in power. If I had spent that in a turbo I would have a 12 second car by now. You can go NA, build the hell out of the engine, and run 100-150 shot of N2O, but it sucks having to fill the bottle.

Go turbo.

lets talk decibels....what are the cops like where you live?

n/a could turn out pretty loud if you're looking for serious grunt.

turbo...nice an quiet

A good turbo kit can get very costly as well. I've got about 1200 in my motor now and I will have the cams pistons and cam gears in. along with a CAI and custom mandrel not crush but mandrel bent cat-back with enlarged flanges. With the correct tuning you can have a 180 hp NA protege fairly easily....you have to remember in this whoel thing its more fun to drive a slow car fast than it is a fast car slow. I mean where in the US are you responably going to be able to run a turbo car to its potential without being in chance of getting in trouble with the law. A NA car can get you in trouble also but not as easily trust me I know from experince here. Once you have teh turbo on your car you are too involved in who hears your BOV and making sure everyone around you knows you have a turbo in your car this alone can cause problems. NA you aren't as involved in it as you open your hood and all they see is the typical header CAI and maybe some cam gears but you can hide those. But its all in personal tastes everyone on this board is goign to tell you to go turbo and yes turbo is fun but it isn't all that.

I smell a good ol' N/A - F/I debate about to spark up.

Tastes Great....... oh sorry wrong thread.

personally im going N/A i have a 5 year warranty and want to keep it. probably Travlers header, and intake. the mazdaspeed cams. dont know if i want to pay the shop to put in the high compression pistions. and maybe the AFC to tune like people said.

LOL! good call...

personally if i do anything with the car, it'll be N/A. too much power in a FWD car is ridiculous....IMO.

if i want a turbo, i'll buy a car that comes with one from the factory....i.e., WRX.

LESS FILLING.

RIght, now that that's out of the way.
N/A tune ups are no less likely to void the warranty than turbos. OF course, it sounds like you're gonna have the dealer put it on, so maybe that's better. Wanna know an old excuse?......
"Just 'cause we put it on for you doesnt mean it's covered by warranty." This holds true even for mazdaspeed parts. Get it in writing. And if they can "prove" you've been racing, your warranty is immediately voided.
I'm dead serious. You get caught Auto-xing or dragging, you're warrantyless.

"Too much power?" WTF is that?

LESS FILLING

 

[Concept P5]

see this isnt really a debate.. just trying to figure out every tuner's problem..... N/A or Turbo.
i know what u mean CHDesigns..... i love teh fact that i got so much hp with no F/I of any kind..... meaning its my motor..... nothing else..... but i cannot deny the fact that a turbo is great to have

CH- is there anyway to reach 200hp by N/A on the 2.0L?
i mean u have yet to port polish and bore right?
if i follow my n/A tuning as per above..... do u think the 200hp will be reached? cheaper than a turbo

 

[peter]

"Too much power?" WTF is that?

heh, right on... an LSD would seriously be needed . . . hell, it's needed on the stock P5...

i get your point, though. funny, though, how subaru gives you an SCCA membership when you buy a WRX, but if you actually use it, heh, guess what?
:bs:

SOA is a bunch of idiots anyway.

let's hope MOA is better.

Amen to that. My family was always fortunate enough to have cars built up just for SCCA, we never used our streeters.

And with regards to the LSD (god YES we need one), I'm actually looking into that. As mods go, it's easy to do (minus taking out the engine). It's pretty much a one part swap (just the diff), and of course there's no adjusting, just selection of clutch point.
This site is great:

LSD is explained on like page 7 or so.

TASTES GREAT

your right, if i did have them do anything i would get it in writing, but luckly they told me about that, i didnt have to ask them. and your right about the racing though. just cant let them see me. luckly there is two or three blue MP3s in the Kansas city area so they would have to prove its me. Which is easy just go to SCCA and get the form i signed. and you can never have to much power

TASTES GREAT

 

[blynzoo]

TASTES LESS, GREAT FILLING ("that's what she told me last night when I took her home!")
Wait, wasn't there a topic for this thread?

 

[Concept P5]

hey hey come on guys get back on topic! lol its serious to me.... i have to decide that way i can start now

 

[promp3]

whats the chdesigns address?

sorry, homeskillet.

I fear asking this question is going to start flames every time. N/A is N/A, F/I is F/I. Keep in mind, that in competition racing, the only time racers dont use F/I is when they're mandated not to. Superdrags could be making well over 10,000 horsepower if they'd let 'em use turbo. Turbo is cheaper, and does not necessarily shorten engine life. HOWEVER, some folks just love a custom N/A, as you said earlier...

i love teh fact that i got so much hp with no F/I of any kind..... meaning its my motor

Overall, turbo is cheaper and offers greater power gains. N/A keeps it "your car," and is a lot cooler from the build aspect, as there's so much more cool stuff to do (also read: "more work"). Also, with N/A the mods are never done, you can keep adding little things ad nauseum.

Why not combine the best of both? Take away a lot of the N/A mods. Get a turbo, (FI) intercooler (FI), and all accompanying parts, then change cam gears, rods and pistons, valves as you would on a NA car. the cost would be comparable.

I guess I dont understand where the hesitation is coming from, other than wanting to keep "your motor." Anyway you do it, it's still "yours."

 

[NYCZMP3]

CAMS on F/I cars

HOLD ON...i thought a higher lift and duration are bad for the turbo cars....this isnt true?...so if i go turbo i should get a more aggressive grinded....what intake or exhaust cam....i would think exhaust no????/....anyone know bout this

 

[chdesign]

The JDM cams would probably be good for turbo as tehy are matched lifts and pretty much the same duration so there isn't any overlap unless you use cam gears. As for the 200 hp NA mark yes it can be done. Roger Foo's protege makes in excess of 230 hp and thats with the stock heads due to Speed World Challenge rules along with the Tripoint Protege that makes about the same power but remember both these cars use Stand Alone engine managment and we aren't talking Haltech here we are talking MoTec.

 

[Antoine]

Even with what seems like most running F/I setups in the import world...there is a very dedicated group who run awesome all motor setups...comes down to preference.

Also there are several advantages and disadvantages for each setup in terms of everyday drivability. A mild F/I setup seems like it would be the better choice in terms of everyday drivability.

What do you guys think?

 

[chdesign]

Here is another view on it from me used to be that the rare fast cars were the ones with turbos and most cars were NA but now pretty much every import in the US that wants to go fast is turbo or S/C so I figured why not go against the mainstream and go N/A sounds kida weird doesn't it.
