Say I wanna throw some parts into a car, but I don't wanna fully tune it up, but reach a certain HP limitation, what are the parts that, aside from raising the HP, raise the torque the most?
Mods that boost the torque?

Torque and Hp are related. Anything that increases Hp, will and should increase torque

Yeah, I'm quite aware of that, but say, if a computer chip part raises the power by 15hp, and the torque by say 20Nm, and let's suppose a sports mufler also raises the power by 15, will it increase the torque by 20Nm also or will different parts give different torque raises? I wanna find out which parts give more torque boost.
I hope I'm making myself clear, english not my main language.

I think it's quite clear what he's asking. He just wants to know, of all the parts, which have the greatest torque gain?

If you are after raising torque as much as possible with raising hp as little as possible, use mods which add power in lower rev regions. That doesn't help very much when racing however, because you will mainly use the upper rev range. Still, you can use mods which boost the torque evenly. From the top of my head:
Use:
ECU tuning
Stage 1 and maybe 2 turbo
Supercharger
Avoid:
Exhaust tuning
Intake tuning
Stage 3 turbo

the part that gives the most Hp gain.
Power = Torque * Angular velocity
even if you use a low rpm turbo, the hp gain will increase torque proportionally.
The drive train mods might increase just torque (as they make the converion of Hp to torque more efficient) but this im not sure about, will have to check

I understand this. I was just making it clear that he wants specific parts which have the largest torque gains. Lol, I knew I'd get this reply back sooner or later.
But, like you said, drivetrain mods may also give some torque as well.

But some mods increase rpm more than others, right? Thus, they gain the HP by increasing rpm, not the torque alone.
I might be wrong, of course, that's why I'm asking.

The three N/A tuning stages usually raise the redline by quite a bit, but they also raise torque, usually also at higher revs. Please don't quote me on that though, I'm not entirely sure. Check the info text of each mod to see what it does. When it says that it increases power at higher revs, avoid it.
...And by using that formula, you are able understand why a low rpm turbo is a good mod. A low rpm turbo will increase the turning moment (torque) of the engine, and due to the multiplier (rpm) being a lower value, it results in a lower overall change to peak power. Essentially, it will increase power over a greater proportion of the rev range than, for example, a racing exhaust.
Some of the drivetrain mods (such as a lightweight flywheel) reduce the forces that the engine needs to overcome in order to transmit drive to the wheels, thereby giving performance gains without any increase in power.

Do the R10 TDi mod
... but seriously, in real life a lighter crank pulley, porting and polishing etc. will give u better low-end TQ/ throttle response. That's probably equal to stage1 or 2 in the game. Also keeping some backpressure on naturally aspirated cars help too... meaning, don't put a full racing exhaust & hi-flow cat and expect low-mid range torque numbers to go up... if anything all the numbers shift to the right of the dyno graph. Turbo cars are the opposite, where you DO want to open up the exhaust path...
If you are running on a course with lots of tight corners and not too many log straights... try getting the custom transmission and loweirng the top speed... essentially shortening the gear ratios... which iincreases the torque multiplier. Carbon drive shaft and lightweight flywheel also help with throttle response. But in the end, you know the saying "there's no replacement for displacement.."

This is untrue, for the reasons pippin4652 already mentioned. As a specific example, the Mazda 787b High-RPM Turbo adds considerably more horsepower than the Middle-RPM Turbo does. However, the car equipped with the Middle-RPM Turbo has a dozen or so more lb-ft than the one with the High-RPM turbo.
the equation for horsepower is actually torque * rpm / 5250. so like everyone said, the lower rpm parts will gain the most torque with the least horsepower.
not to be a dick or anything but your equation has nothing to do with horsepower.
Stage 3 Engine raises the Rev Limiter.

youre not being a dick, you just dont know what youre talking about
Power (HP) = Torque * angular velocity
= Power (HP) = (Torque * RPM)/5252
Why some cars gain more torque than others when modded are their own personal traits. This is also why cars gain different levels of RPM. each is unique. Just like some cars can be max modded more than others.
What you are talking about are the cars own traits. Every model car has its own. On some cars adding the high rpm turbo, will actually decrease or make almost no difference to torque or Hp. Just because their "sweet spot" is in the mid or low rpm range. Their specific engines wernt built for the higher level mods.

I think the point of contention is how people define torque and horsepower. They are basically the same thing.
The problem is, if you're looking to maximize torque, you're looking at it the wrong way... a zillion foot-pounds of torque just off-idle won't help you... but a nice 50-100 ft lb bonus midrange will count for a lot.
It's best to look at things in terms of powerband. Which means: the most torque/hp under the curve at the most useful rpms.
Basically, you'll have to buy and experiment for each car. I've done this for some TTs, but I don't have the time to fiddle with everything. Stage 1 and Stage 2 turbos are generally good for this... and some combinations of exhaust and intake give more torque per hp... but it varies.
One peculiarity noted by some TT'ers is that dirty oil is one of the best power-boosters available if you're trying to meet a power cap. Simply because it takes more power away from the high end than from the low end, leaving you with a fatter powerband.

1800 lb ft off idle will do A LOT actually if you have the right gearing. Look at the citroen concept for example, 1 gear, yet has 1800 lb ft up to 1000 rpm and starts dropping after that. hell drag race someone with that thing in reverse and youll see you can hit almost 180 mph in reverse.

It's things like this that make me want Forza's level of customization in GT5. You could add parts that help increase torque (Displacement, Gear Ratios, Cam values, and even good ol Aspiration and drivetrain conversions). But like Niky said, dirty oil helps a lot. I assume you want torque for rally events, and a Subaru Legacy 2.0 with dirty oil and no mods will beat all of the stage 1 events, and a stage 1 or 2 turbo along with the 20K transmission and all of the drive train upgrades can hold it's own against stage 2 rally.
Not sure if this helps...

That's because it still makes torque after that.
I've driven vehicles with lots of torque. But torque that drops straight off a cliff after around 2500 rpm. They get up and go quick, but gearing can't completely make up for a lack of torque at higher rpms... that's because gearing multiplies torque... and once you've shifted into a higher gear to make up for your lack of high rpm torque, you've lost the benefit of torque multiplication from the lower gear.
So there's something to be said about making power over as wide a spread as possible.
