Im begging to wonder, how developed will the NA route be in the near future? Do you guys think we are gonna achieve high power going all NA?

A great amount of power is achievable NA, but will be very very very costly while requiring very very very costly fuel.

i never really understood why some people (with a lot of money to spend) would rather spend it on NA rather than FI

i used to think that way...but if its def possible to build a safe FI car that will give you way more power than you can get with EVERY na mod

i just dont get it....unless people have a specific reason to stay all motor

How will the mileage change with FI?

I think you'll see lots of NA progress in the near future

I am more worry about what shops has techs that are knowledge enough to tuned the Z NA.

Judging from NSX's experience. there are no one in the US really know how to NA tuned that car, and it's already been out for so many years.

beccause they are so freaking expensive to buy/invest. The average person who had the money to buy a NSX will buy a different car.

Hints?

Now why did you have to that. Lol. Lol. A hint would be nice. We can figure out the rest. Lol.

I'm doing NA mods right now cause they're simple and easy to do.

I need a reliable car since this is my daily driver.

I'm getting a lotus elise in 8 months so I can do more tinkering on that, but NA is probably more consistent as far as reliability vs FI. (I know it isn't always the case, just I don't feel safe going down the FI path without a backup car. That and I can't afford to have somethign go wrong and have my elise money go towards fixing my Z)

That and I've decided that owning a sports car is about having fun driving. Going fast is fun (like as in FI) but I also think having a lightweight clutch/flywheel, lower gears, meaner sounding engine and better suspension is more fun than just FI alone. Since I'm not made of money, I had to decide between just FI by itself or all bolt ons, suspension, ECU etc etc

For some people, power is not everything. If you really look into the Z it is built to have very good weight balance. Putting on a FI system might throw it off. I think NA is good for those who want a little more speed in their ride while retaining balance. It just depends on your application. If you install turbo there are issues like lag while NA you get a smoother powerband etc. There are lots of reasons.

zlex

O yea and if you go FI, you will need to reinforce many other attributes of your car such as suspension, sways, brakes, etc.

kzshin

I already mod FI cars before. So I want to try something different, that's why I want to do NA.

Regardsing, NSX. There are alot of used NSX around now, and you do see people tuned NSX, however, in US, so far I have seen are all FI, not NA. When I went to Japan, most NSX there are tuned NA, and some of NA NSX's HP figure are higher than the FI NSX we have here.

KZshim - even in Japan the NSX is not a car to get if NA power is what you want. NA power on modern cars is a very difficult thing to achieve without big displacement/compression - something neither the Z nor the NXS have.

turbo-maxima

The NSX engine is extremely reliable. They don't even stock NSX parts here in america, everything must be ordered from Japan. I think the S2000 with a V6 would be a equal replacement for the NSX except for body styling. S2000 is like half the size. They have gotten 450+ N/A horsepower from NSx engines without increasing the compression ratio that much. Still able to run on street gas but they have higher octane gas in japan. I think 450 whp is possiable without a stroker kit. I would say using the Vq30 crank and rods making it easier to to rev into the 9000+ range. thats the only way too make big power. And Individual throttle bodies must have to be used. 9000 rpm with close gears would be incrediable.

Going NA has some upsides and downsides. There are three reasons I have stayed NA. In my opinion, both are expensive if you do it right.

1. Reliability - until some really solid fuel management and timing control comes along that is readily available, then FI is not safe enough for me.

2. Driveability - An NA setup is very predictable and much easier to drive out on the road. An FI setup is not as predictable, it takes mad upgrades in all aspects of the suspension, traction and braking to really control the power.

3. Future - when fuel management and timing control are really hammered out and FI is a very safe route, then I will have a very mean setup with cams, exhaust, suspension and so on. Going FI after NA doesn't mean all the NA mods are now worthless.

heres what you need:

Tilton flywheel/clutch
crawford package
Nismo LMGT4 wheels
full CF front end
intake
stillen exhaust
oil, tranny, steering coolers
upgraded radiator
fully customizable suspension


there, sweet NA power, no expensive fuel

axxizzer

oh yes, and AEBS sleeves bored to 100mm

I would add the 3.9 final drive and LSD to the list. But yeah, that list would be a mid 12 second car on slicks.

axxizzer

...dunno about teh 3.9 and the tilton, sounds like it'd hit its peak REALLY quickly

And might have a drastically lower top-end

and forgot to add
NISMO cams to that list
