I was looking for more horsepower for my 1998 2.5 tl and the only things that seem capable are the weapon r intakes or the venom 400 (which looks like a scam). If anyone could tell me the real results or specs given from these, or help me find something else. any suggestions would be great.

welcome to the forum. Yeah,the 2.5's upgrding potential is pretty limiited due to lack of aftermarket support. Used to be a guy on here who had a custom turbo made for his 2.5. Think it was based off a Garret T3/T4. I believe he was running low 14's, high 13's with his setup. Not sure about any other mods that would add significant horsepower. Maybe consider swapping in a 5 speed manual tranny from a Vigor? That would free up some horses and give you an extra cog to work with.

Venom is a scam. Total bullshit. Dont waste your time and money.

you can do the usual, or what i call the usual, upgrades:

plugs, wires, K&N air filter. i stuck with stock plugs/wires, and did the K&N. i don't know if it adds much hp at all, but any little bit can help.

First thing is definately "Stage 0". All the basic maint stuff, make sure that you have a solid platform to start from.

Other than that, dub has most of it covered, some say grounding kits too. Maybe something in the fuel system? I believe someone here has a fuel pressure regulator.

He has a throttle rotor too, quickens throttle response, which won't make you too much faster from a stop I don't think, but would probably help from a roll.

A 5 speed swap would work well too.

Light weight rims? Ditching rotating wieght is always a good thing, though I haven't really seen anything around (haven't looked either).

PDX3.2TL

the 2.5 motor is just the f22 bored out .3 liters right? If that is so all the bolt ons for the f22 should work just fine? i have a 2nd gen... just beating around the bush...

cambo

nope. The 2.5 is a 5 cylinder motor. Only the vigor and the 2.5 tl uses this motor. I believe its a g-series motor?

dubcnea

the G must stand for "Good luck trying to find anything for this motor". or some such

how much of a difference would you say one can feel in the 2.5 and the 3.2 because I heard about how it is not 176 but 190 or whatever, and thats only 10 horses. I'm just getting tired of the lack of power and the realllllllllly rough gear shifts (maybe thats just my car, any info on that would be helpful), and how reviews say the 3.2 is "smooth and silky" compared to the 2.5.

UnsanePyro

I don't know about the difference between the two, but the 2.5 feels pretty quick, especially being only 16-18 years old and probably not haven driven many faster cars. I wouldn't say the 2.5 has a severe lack of power, and my shifts are pretty smooth as long as the RPMs are right, too low and they are a little rough, too high (7000) and they are sorta rough, but there defiantely seems to be a sweet spot.

flipskatemer

Alright well I'll probably just end up trying to get a secret weapon r short ram intake when I have the money and hopefully that'll give me something. But first, time for subs.

i think the venom just advances the timing on the engine from the ECU to make for a quicker response.. some have dynoed and said there were results but im not about to spend all that money for that... for that price i would rather invest in a mild shot of NOS... but i have never driven a 2.5 but my 3.2 is quick.. i was surprised i kept up with some of the new gen maximas... 2000-2003 models... i just wish i could find a damn strut bar...

HQuakers

If you are looking for serious speed, then sell the car and get something else...this car isn't made to be a race car..you could just do everything everyone else said including the nitrous and you might get some decent response.

flipskatemer

Well I didn't buy it as I'm only 16. It was pretty much my choice and I do love it, I've just, however, found it to be lackluster in the power area and wanted some help. I just want to have a car that won't get beat by like my friend's Yukon Denali, my other friend's like old mercury, the mazda 6, or some frigging SUV. But no biggie, it's luxurious and I'll just get a sick sound system or something.

UnsanePyro

Do you know that all of them are faster then you? From a roll? From a stop? My dad's truck is great from a stop (for a truck) but from a roll, forget about it, it isn't going anywhere.

Just think about all the power options, leather, milage and things like that that you have, and reliability. Keep in mind the price you paid too, I know people around here who have spent 10K on cars, and they are faster then me, but for double the price. It's all about perspective.

dubcnea

also remember that the denali is close to 300 hp. it weighs more than our cars, but 100+ hp is just that.....lots more. plus they have more torque, etc. neither vehicle is geared for racing and what not, but most cars aren't. what mercury? that one that looks like an older mustang? cuz i've seen some of those that can fly if set up right. the mazda 6 has like 210 hp. and if it's a stick, could be a bit faster with the right driver. SUV...same as denali. just gotta kinda pick and choose the races. and don't worry, when they are all fixing their busted shits, you can roll by with your car still running smooth. reliability, in the end, conquers all.

flipskatemer

I'm very happy with my car, but the fact that MOST cars could beat mine is kinda unnerving. They supposedly do 0-60 in like 9 seconds and to tell the truth, I was just expecting more. I'm happy that mine is reliable, luxurious, and an incredible deal, and not that that isn't great but you have to understand that getting a good deal isn't as important to a teen as power...However, I've said this several times: I do love my car I just wanted some extra stuff.

vishnus11

i get what your saying. 0-60 in9 seconds aint stellar. A manual tranny swap from a vigor would drop that a second, and make the car more fun to drive. Cold air intake would help. But above all, custom turbo, (which has been done before) would ROCK.

wackjum

I know when you're young, it's all about speed and seeing who's quicker. First of all though, speed kills. Maybe it won't kill you, but you'll lose your car (has happened to me twice).

Secondly, making a 2.5 faster to beat SUVs or a Mazda 6 is such small time. I remember when I drove an NA Supra for a while. I though that thing was the shit.

But the first time you get yourself in a Corvette or some other higher end performance car (a turbo Supra), putting in an exhaust and intake to gain 5 hp suddenly seems completely not worth it.

There will always be somebody faster. At least until you get to multi-millionaire status. Z28 Camaros and such are becoming dirt cheap. Anybody can go out and get one of those for less than 5 grand. There is nothing you can do to your TL to beat one of those monsters. You can laugh at them and say oh I got a nice interior that isn't falling apart, or you can just not care and realize some cars are sports cars and some cars are passenger sedans.

wackjum

Eh I might be taken the wrong way on my previous post.

Modding is fun. It's like over clocking. Getting more out of what you paid for. My TL has a CAI too.

But what I was referring to was spending lots and lots of money/time to make a sedate passenger car becoming some kind of sports car.

Ken1997TL

The 2.5 engine is a G25 motor, its only relative is the G20 motor, you guessed it, a 2.0 liter 5 cylinder that was mostly in Japan and a few export markets.

vishnus11

i THINK what hes trying to say though is that its kinda embarssing when your getting passed up by a freakin Yukon etc. I doubt he has ambitions (at least yet!) to dust Z28s buyt he's just lookin for a lil extra oomph. Nothing wrong with that in my book! Just as long as NO RICE.

wackjum

Ok true that. But like it's been said before, those SUVs have nothing beyond 40. They're all about initial launch torque. The exception would be "SUVs" like the Infiniti FX. But certainly anything domestic.

I'm pretty sure a 2.5 could those on. Don't look at the magazine published numbers.

FastHarry

I belive my car is pretty quick. I raced a supercharged H2 the other night from a roll and he wasnt pullin on me very much or vise versa. You just need to learn how to drive. As for moddin it throw some cold air on and exhaust. The response is much greater and a little more pick up. If you cant find either have a shop do it. Theres a shop in my town that custom makes exhaust and some other stuff.
