Most Economical Way to add Low End Torque?
 

Hi, I just got my 8 a couple months ago and was wondering if there was a cheap way to add a little more low end torque w/out doing f.i.

a new flux capacitor should help.
Aftermarket ones look like this: http://i21.ebayimg.com/02/i/001/10/f8/7a01_3.JPG

Sell it and buy a GTO

An 8 year old mustang GT would be cheaper than a GTO. By to the OP there is no further reason to keep this thread open, you should delete your post and make this go away. There are no cheap ways to add power to this car. Your question has been asked since 2002 and the answer is the same FI or Nitrous

Remove your VFAD (free) and add a K&N flat filter (~$50) and it will feel like you have more low end torque. ;)

dude no way of add torque other than buy a accesport for a leaner tune and increase hp

This is usually how I add low end torque to small displacement motors...

drive downhill?

all the bolt on NA mods in the world still won't give you jack squat for torque.

Get a turbo if you want torque, it won't be cheap, but you can double (or more) the stock toque fairly easily with it.

If the car is on the road and not on a dyno machine, I think final drive can help a bit. Else, down grade the rim/tire size :)

If calculate HP/$ , then Kane's idea is a so true :)

assholes lol

depends on the torque u want to achieve vs investment

example:

option 1: $4600 = maybe 40-60 hp
cobb ap - $700
bhr ignition-$500
act clutch kit- $400
prolite flywheel- $250
pwr radiator- $400
good coilover suspension kit- $1000
front & rear sway bars- $400
pulley kit - $300
add the labor cost to install all the above $1000

Option 2 = $3500 depends tuning + 100hp
turbo $2800
cobb ap- $700

conclusion if u bought a Rx8 thinking you can modify like a cheap car, spend big or go home

oh boy, here we go...

while noturd here is on the right track, take any of those numbers for a grain of salt.

from option one - 1)its possible to see 20hp from tuning but very unlikely unless you've already spent the money getting rid of the cat converter 2)its possible to regain horsepower lost through shitty coils, but extremely unlikely to add any actual measurable power 3)between the clutch and flywheel, IF you choose the right ones(not what you see in that list) you can remove enough mass to see 5-8whp improvement via efficiency 4)pulleys have been questionably assigned 1-2hp gains... So, as you can see the couple of bolt on power adders listed arent really adding up to much. You also have headers, extensive exhaust customization etc etc that you can play with. You have the option of extensive intake customization but guarantee whatever you can gain at a given rpm, you will loose elsewhere and then some. To date the best reputable dyno result from an NA car is about 220WHP. thats roughly 40whp improvement over stock with extremely good tuning. most people are lucky to see 200WHP

from option two - $3500 is not even a place to start. double it and you being more realistic. the truth is your looking at 2800 minimum for the cheapest kit availible. you still need gauges and the associated equipment, boost control, installation, dozens of minor things that do add very quickly, Oh - and unless you plan to be rebuilding the turbo/motor very quickly - you'll be replacing half the parts that come with such a low cost kit(including having the turbo itself upgraded)....
-i know this may seem a bit harsh to some, but dozens of others here can vouch for the expense. you cannot count the times new guys have come here, boosted their motor, not spent the due time and diligence researching nor the due cost doing it properly, then 3 months later blowing a motor and selling all their parts to pay for a rebuild - then selling the car. I personally was inches from being boosted - I had in possesion most of the parts to go ahead with the install, i was looking at a total cost of no less than $7K. I sold everything I had - I decided I was NOT gong to be one of those guys who boosts a motor I cannot afford to loose. I will be back to the turbo route one day, but it's flat out irresponsible financially to boost a motor that you cannot afford to loose.

the plus side - the FI route can easily put you to the 250-350+whp range.

in conclusion your options are:
1) bolt ons - 20(realistic) to 40(max) horsepower gain at a cost of hundreds to thousands
2) forced induction - 70-100+ horsepower gain at a cost of $5K+(minimum!) and hopefully in doing so, being in a financial/logistical position where you can afford to loose the motor and not have it turn your day to day life upside down

Paul you always come back at the worst times :lol:

^+1

Yeah seriously. What are the Chances?!

what can i say?:D:

someone has to keep a leash on all the poor information being thrown around the forum these days

btw edited my post :)

I love how Pauls avatar seems like its actually looking at the person he quoted. So awesome.

P.S. Love the Sig, Love the Avatar.

You bought a car with a small engine yet you want low end power and don't want forced induction. Here's the problem. Torque is directly proportional to displacement and hence horsepower is also affected. It is a force applied over an area. Having small displacement means that you don't have much area. That means you need more force which is only going to happen with forced induction. If you don't want forced induction then you need more area which means a bigger engine. What you are asking quite frankly isn't going to happen. You have 3 options. 1: sell the car and buy something with a bigger engine. 2: live with what you've got. 3: forced induction. Not an asshole response. Just an honest one. What you ask is impossible.

FI or Die.

LOL it's so true tho. Good job, Paul :ylsuper:

If anyone thinks they can turbo an 8 on a tight budget, they are neglecting the biggest expense- they engine they will eventually blow.

So then they will become another one of the countless people on here that boost this car on a shoestring budget, blow the motor, cry about it, then sell all the parts and eventually sell the car and buy their Evo.

You can't turbo this car very cheaply. I think I got a GREAT deal on my used GReddy kit, but the turbo was trashed, I could have gotten it rebuilt (No BNR upgrade then tho) and I decided to not half ass it and upgrade the snail and other stuff. I think I've dropped over $6k on my turbo including parts, multiple dyno trips, trying different parts, etc.

Forget the engine, you might blow a Transmission. Hows that comin BTW Wafer?

I got it fixed- I'm sweet like that haha

T-400 with a ratchet shifter????? HAHAHHA

Low end grunt for about 10K

Those vids sucked, Kane! It would have been infinitely more entertaining if you took that Jeep off some sweet jumps or something.

It's funny because my DD in the winter is a '93 Ford F-350 with a 460 big block. It will spin it's 36" all terrain rubber (whole lot of tire) easy in 2nd gear from 1800 rpm, gotta love low-end torque
