There are some cars that will accept either NA or Turbo upgrades. The Lotus Elise comes to mind, as does the Honda S2000.
You can equip it with either/or.
This way you can run it in NA contests or you can put the turbo back on and run in Turbo contests.
When I have gobs of cash I will put every possible option on some cars so that I can run them at HP levels that I choose.
I have also used these options to "even up" the competition between the regular S2000 and the Tuner S2000's.

Just wanted to add to this subject.
You see, I love the NA vs Turbo idea.
The RGT is perfect for this disscussion.
There are some great differences already mentioned and for the sake of speed I will not repeat those points.
However, one thing I think no one mentioned is engine note.
I love a fully NA tuned rgt.
Not another tuned road car in the game like it. 👍
Btw, another important factor in picking between turbo and na is the level of tuning you want to go with.
If you want to hit a certain pwr, or if you just want to keep a car with-in its limits, the NA tuning can be your best bet.
Anyway, good question. 👍

The characteristics of a car in stock tune are identical from car to car when comparing cars of the same make and model. However, cars that are in stock trim, identical, can be reborn with completely different characteristics thanks to different tuning approaches. In the case of the rear wheel drive car, this is an excellent example:
Mechanical tuning doesn't require turbines or compressors. Let's say you have one driver in a non-turbo Lingenfelter Camaro 427. The engine speed directly responds to accelerator imput. This immediate response is a big advantage off of corners. Even after entering corners at maximum speed, mechanical tuning allows delicate control of power to the rear wheels, so the 427 driver can push the car harder. So, compared to a turbo kit, he can perform more agressive turn in. His entry speed is higher. His competetor pilots a Twin-Turbo Lingenfelter 383 Trans-Am. The Trans-Am is a little dull on response in the corner, but the added horsepower can make up for it on the straightaways. The turbo car is better on the exit. Being turbocharged also means a big lag when letting off the accelerator, so once the boost pressure comes down, the pickup is slow. So if the Trans-Am's rear end becomes unstable, the driver will hang on and compensate with countersteer. In contrast, when the Camaro loses rear traction, the driver can let off the accelerator then get back on it once the rear has regained traction. The Trans-Am is better suited for a track with long straightaways. The Camaro is better suited to a complex track with many corners.

Right, I hadn't looked at it that way. There is indeed more to a car's performance than just break horsepowers. Guess it's a fairly good option then to have both installed and use either at the right times considering the track. Thanks a lot guys.
Side question: If I lost, say, 8 HPs because I didn't change the oil in time, is it ever coming back? (guess not huh?)

um...would it be better to add Turbo or N/A on a Toyota Sprinter AE86 Trueno

That'd depend on what you want to do with it. I find that the lvl3 NA tune up is enough for my drifting purposes. But either of them are good. Again it depends on the purpose.

Well, unless I'm mistaken, the boost pressure comes down the instand you let your foot off the gas pedal and the turbo spool loses speed, then the turbo takes about maybe 3/4 of a second to get back up to speed. Boost Lee's turbo (the milkjug avatar) is like that.
Don't the earlier Lancer Evolutions have a 'misfiring system' to cut down on the lag?

I completely forgot that missfiring-system. I don't know have it been in Lancers anyway. I've read an issue about Porsche "Kremer K3" DP 935. It was a 700bhp Porsche and was raced in Lemans by an "civil team", I don't know the right word but it wasn't any car makers race car and it won at Lemans! It had to driven so that boost won't drop and it doesn't have any missfiring-system. You had to brake very early in turn and then push the gas pedal trough the whole turn so the boost wouldn't drop and it worked. It must have been very though car to drive but very good too.

Well this is from an IniD fanatic but Sudo's Evo 3 goes bang-bang every time he lets off the throttle and enters a corner. Plus I've heard a very similar noise coming from WRC cars when I watch them on TV, mainly the STi's, 206's and EVOs. I'm not anywhere near close to 100% positive on that, but I'll bet earlier Evolution GSR's came with the system.

So your saying the RGT sounds better with N/A mods than Turbo? I should check that out, whenever I have a car with the option of turbo, I turbo it. It's not like the turbo'ed RGT doesn't sounds bad right?
It really depends on personal preference.. Turbo conversions make more power, give more torque down low to mid range (straights, hill climbs will be a lot faster), but it is true that it lags b4 the turbo spool up. Misfireing system or "bang-bang" is a system where som gasoline is beeing let into exhaust system after you accele-off and it keeps the turbo at high rpm, so instant response (full boost) is provided whe say exiting a corner.. I dont think any of the lan-evos had a misfireing system stock. The car in the Anime Initial D is probably rally tuned. It would be unexceptable to put bang-bang into a stock car. Two reasons. Fuel consumption increases tripple fold + the authorities wouldnt be exactly keen on seeing a car bursting flames on the streets. Thats how i think..
Back to turbo or NA. I take NA when a car is NA or Turbo kit if it already has a turbo. Overall i preferre NA response, high revving.. its really a matter of certoin car and the track you'll be racing.. for instance in Deep Forest II i couldnt do a faster lap whit a the turbo on my Integra TR, than i could when it was NA, despite turbo providing lik 80 hp more; fully equipped in both cases. This track is very dynamic (corner > corner > corner), thats why hp doesnt matter that much, than response. But for instance in Laguna Seca where you have a straight > corner > straight > corner > straight > corner, hp matters. i have two civics VTi. one turbo and one NA, both fully equipped. The beste lap time whit a turbo eg6 was almost 2 seconds better than i could do with a NA eg6.
So how to decide? Test it! Large turbos (top end power) in FWD cars are im most cases invain, because even with the best LSD setup, you'll still go straight in a corner if you floor it. In RWD cars, when you get more torque from turbo, wheels will be easier to spin, thus gettin more of a jumpy behaviour.. (drift_press) - Thats another big difference in turbo vs. NA. Na gives a more linear increase in torque, unlike turbos. When a turbo spools up it provides instant boost, torque increasses dramatically and it keeps going til the end. If you would look at a dyno chart you can see that turbo cars have the same amount of torque from the spool up (cca 2-3000 rpm for small turbos and 5-6000 for huge turbos) to the end of the torque band. Wherey NA motors have a more linear increase. The torque is incereasing from the start to the end (anywhere from 6 to 10.000 rpm).
So if we take this into a corner, say you have a car with 200 lb-ft torque, you are going.. the second gear is too short, so you go into a corner with 3rd. but when you give it gas you loose rear end.. you need a bit less torque.. but with such a torque band its harder than when you have such a wide range with NA.. you can pinpoint accuratelly provide as much torque as you like.. the difference isnt that big, i cant explain it good , but when youll play alot youll notice all the small things that make your run a bit faster..
Anywho, try both out, try it on different tracks, and decide what most suits you. Its very importaint that you go through this game learning, and not just taking setups from ppl from the net, never knowing why the setups are like so.. its good to take them into consideration, and than try to find what best suits you and your driving style..

NA's sound better when revved.
Although, the blow-off sound is addicting

Na has other sound then Turbo,that's crap.I prefer Turbo,much easier for handling the throttle.
