Looking for naturally aspirated guide

[wozzah1975]

Actually I am not so sure my car have the VT engine or not, can I tell from the spark plugs? I only have two compare with the previous version.

I really don't have patient to save up to $10000 for turbo, I love N/A is because its allow me to change parts bit by bit, I am not trying to do a engine swrap until the engine die, so at the moment I have a K&N cold air intake, what else can I change for next step? Can someone provide a detailed guide please? I really love the way that changing the car little by little and know my car:)

See above post

.. VT, as in the SVT engine?
if your speedo/odo dials are white and fog lights come standard..then yours is the NB8B with the SVT engine

I think you need to rethink how expensive going turbo is. Also be careful when you throw prices around like that (you might get school'd by Dann on how cheap going turbo is).

It also seems that your after some kind of general guide on modifying a car, honestly there is not one specific way to do things with cars. Some people go for aesthetics, suspension or engine and it seems you want to tackle the engine side first.

Generally with Engine modifications people normally put an intake > exhaust ( this includes headers + cat + muffler) and generally about here people just stop because they it gets more expensive as others have pointed out. After performing exhaust modification you will have to change the engine itself in some aspects whether its camshafts, Port n Polish, upgrade valves etc its going to be expensive, real expensive. Also you should take note that kw per dollar is not justified compared to turbo.

To give a idea you may want to look at Yuge's build Here. Yuge pretty much has a maxed out mx5 1.6 (i know its not the same, but the mods he performed are essential the same thing you would go through) and his only making 104rkw. Don't get me wrong N/A is great i'm building my atm, but i'm just warning you now so you dont get dissapointed with the results after you've wacked a tonne of money for minor results.

Yes, the dials are creamy and the fog lights are standard

So should I turbo my car or keep going for N/A? Isn't N/A is cheaper and the engine can last longer because it is not force inductions?

[shuey]

.. well in simple terms, if you calculate kW/dollar spent. the turbo way will be the cheaper option

[koop21]

I can't decide what you should do with your car, that's your choice. I'm just providing you with some examples of what you would have to do with N/A. Going turbo is not a bad thing, it depends if its done correctly. And dont forget these motors originate from a turbo version! As for reliability it depends if your trying to push a crazy amount of boost without supporting the engine to handle it.

N/A is not cheaper when you compare power per dollar. If your thinking only intake and exhaust ONLY then yes its cheaper but compared to turbo.

Once again, this comes down to what you want out of the car and how much you want spend.

But turbo will not let the engine last longer like N/A, isn't it? Also turbo is looking for $10000+ at once but N/A allow me to pay $10000+ separately

Bang for buck? install a 4.1 or lower final drive

Yup, it depends on how deep your pockets are..and whether it's currently full or half-full.
But for the $10k that you're gonna be spending on N/A, it'll still be less than what you'll get if you slap on a turbo.
Personally I'd go N/A unless I've already had an SE base to work on since I typically don't like to tinker all that much with the internals.

u mean SE base is it the one build in 2004? mine is just NB8B, and the reason I go for N/A is i can spend the money bit by bit and after 12 years, maybe also is a good time to put some new parts in.

I'm doing a serious NA at the moment, however it has been in the panning for some time. Wozzah speaks the truth when he said that you need to think about what you are doing as it is easy to go backwards and waste a heap of money.

What is your final budget? You can do things gradually however you need to plan very well. Possibly first is the ECU as all the mods you need will require another ECU then work from there. Have you decided where you want the torque to come on, when do you want the power to come on? Too many questions

Turbo is NO WAY near 10,000. Turbo can be 2000, hell you can drop the car at my place with 3000 dollars and Ill give you a turbo'd car with JUST the basics, around 150whp, and then you can add bigger injectors, blow off valve, clutch, exhaust etc as you go if you want.

Yuge only made 135hp because he had girl cams (No offence intended to any of the forums ladies of course). If he had big compression and 'ManCams' hed have made 170-180whp.

I'm sure Yuge choose what he did because he drives his car on a daily basis and does not what the hassle of a fully worked engine. But yes anythings possible if your throw usability (road use) out the window

[NitroDann]

His cams and compression were FAR smaller than anything that affects driveability.
