[Nupe03]

Hey can anybody please tell me how I can improve the speed and horse power of my 96 automatic Ti without doing a whole lot and putting alot of money into the engine I have change the airfilter and put in a (KN) air filter but I want more power and I want to keep the engine stock as much as I can so I need some advise in what direction I should go. thanks

+2hp? for 250 bucks? geez, i'd rather make a hole in the floor and help the car with my feet.

I'll post about my cam work soon. It's free I suppose, but it's gonna cost me a bit to get the dyno test to actually see the results. It'll be in the next month. Stay tuned...get it...tuned? lol.

I'm holding off on the chip till I do a bit more tuning/intake/exhaust work. Then I'll get them to tune my chip in a bit better to take advantage of those mods.

take out the a/c whoel system, replace the cat wiht a straight pipe. will cost u like $500 at least 20-30 hp

Which one is the expensive one? and which one gives the most horsepower?Taking out the cat is illegal right?

Removing the cat just lets exhaust flow more freely. It's not illegal as far as I know, but you'll probably fail an emissions test. Removing the A/c will reduce paracitic drag on the motor (fewer accessories for the motor to spin means more of the available power gets to go to the wheels).

it's 100% illegal in all 50 states... i know any shop that removes one is fined like $25-50k... something like that... it's not worth the chance. if you put a high flow cat on, you're not going to lose power.

I found this on the EPA website.

I thought so I went to an exhaust shop and asked about the cat question and they said I would have to buy thier shop for them to do that.So I guess it is a big penalty!

Take off the ac wheel.... The california 110 degree valley weather isn't as bad as its made out to be lol

Just remove the belt on the ac. As for the cat we don't have emissions here, but the penalties still apply. However, I just took my car to a local exhaust shop and paid 50 dollars cash with no recepit.

Has anyone ever tried the air conditioning delete mod? Does it really make a difference?

[tEso]

I know a friend who did that in the Hyndai tibron and he removed the AC and everything related to it and gained about 15hp he said the car was lighter and her also removed the cat.. ! both at once and he said he felt a gr8 difference...
I never tried the AC delete mode.. ?
does actually work.. ? because i think it wont make a difference at all...!

[barische]

of course it will improve the hp, u see that belt that turns the ac, the more pressure it puts on the crank the more hp u lose, so just cut the belt, u ll feel the power. take the ac assemly out, u save weight so u go faster, its simple.

[AlaskaBlue]

I was told the a/c was clutched so that the belt really wasn't turning much. I kind of hope that is wrong because it would be nice to remove it and get more power. There is another mod called a fan delete. I am not to sure about that one though.

[stormos]

on my friends 200sx (240sx there) keeping the a/c off saves at least 15% HP.

The cat removal will be the expensive part, cause the fine is huge :eek:
