this 240s got an intake and exhaust....so he's probably pushing around 170hp........

my car is also complete stock and its pushing about 175rwhp...and about 264lbs of rear wheel torque.....


the 240 dude says I would win but his car is pretty quick for what it is....

its also a 5spd manual vs. an automatic tranny

 

What makes you say that?

 

um...every site I have been to and the dyno.............

 

well no comment

 

Those numbers are for the motor, not the vehicle. You do have one advantage thou. You have an automatic.

 

How is an auto an advantage? Less chance of error?

 

well considering everyone complains about the 240's 2.4 which they say is an overworked truck motor it still has about 150hp stock and with his mods he might have upwards of 165 to 170hp and you only have 170 being stock. and also the 240 is quite a bit lighter than our f bodys. and then there is the drive train loss which will be more for you being an auto to his stick. i hate to say it but im gonna put my money on the 240. im a die hard f-body lover but the 240 will turn a corner like its riding on rails and its a quick little car

 

I got the following stats from this website --->http://www.albeedigital.com/supercou...0-60times.html

1995 Nissan 240SX SE 8.3 16.1
1995 Nissan 240SX SE-R 8.0 15.8

Those numbers would be for a new, stock 240 back in '95. I think your race would be pretty close.

 

Stock auto LO3 cars dyno around 150 at the wheels. They make 170hp and 255tq at the crank.

Based on the times that Mike-In-Orange posted I would say this would be a drivers race.

 

I dont get it.....I have talked to other people saying they push around 170rwhp with their LO3s, and just the other day I asked what a stock 98' Trans Am holds at the wheels and sure enough I saw a whopping 305hp at the wheels response. Just to makes ure I wasn't bsing myself I looked at msnautos site and they side 305hp.......


I always thought it was 170hp at the wheels....a few people have told me the LO3s have about 190-200hp at the crank....

 

L03 = 170hp at the crank, anywhere from 140 to 150 at the rear wheels, depending on tune.

Yes, LS1 cars do put down between 290 and 310rwhp depending on auto/6spd, etc. LS1s are grossly under-rated from the factory. They didn't do a whole lot of under-rating with the thirdgens...especially the TBI ones.

 

Thats freaking sad......why does this car seem so much faster....I have to do something about this.

 

It has a wide power curve which gives you that solid acceleration feel. As mentioned, the 3rd gens where never underrated. The Gen II and Gen III motors are horribly underrated. All HP ratings are at the crank with accessories. The reason you see chassis numbers as high as advertised crank numbers are because of this extreme underating. An LS1 will make 400hp on an engine dyno and produce GM's advertised crank ratings (305 to 325) on a chassis dyno. GM does this for various reasons. Ford did the same thing with the last two years of the Cobra.

 

I really wanna make my car atleast 205hp at the wheels, I mean is that even possible...

I want it to be as fast as I can make it but in all reality I dont want to spend alot of money on it.

That makes me kinda sad, but I mean I still like the car for what it looks like, and it handles very well...

 

with TBI mods, advanced timing, full exhaust, headers, intake, and gears, you could easily break into the 14's in an LO3.

then look at heads, rocker arms, cam, and a good chip tune and you'll really be lookin good. well, for an LO3 anyway.

 

The good news is that it's not very hard to make these cars respectable on the street. These cars' engines are very restrictive from the factory so just doing "simple" mods can add a relatively large amount of horsepower. Putting headers, an intake, a decent cam and better heads on the engine will have you very close to 300 bhp. However, since your car is fuel injected, you will have to learn to burn PROMs or have someone else tune it for you to make it as effecient as possible. And, depending on the parts you choose, it can be completely emissions legal as well, if you have to deal with that sort of thing.

EDIT: I forgot to mention that the rest of the car will need to be prepped for the additional horsepower. A higher stall torque convertor will be needed (if yours is an auto), and better rear end gear with a posi would help, too. Most of these cars came with lame gears like 2.73s or 3.08.

 

I am actually looking online on Ebay for some new gears and I can get some 3.42 gears for less than 150 bucks which isnt bad at all...I dunno how much it is to install but I know a few shops around town that might be able to do it for less than 200 bucks maybe...we'll see

that 300bhp sounds nice....I know that these engines are very restrictive from the factory....so if I pull 300bhp I might be chruning out 275-280 at the wheels

 

Or more like 240 at the wheels. That's a lot of power out of a TBI car though. Like said, you'll need heads/cam to get that much for sure.

 

50-100 shot of nitrous gets you to the 200whp number really fast. Motor torque qould probably be up near 400 too.

 

My friend used to have a 240sx. He had intake and exhaust, ran a 16.9. They suck.

 

You need to face the facts man, the L03 is not a performance engine in any form. It is a reliable V8 that gets good gas mileage. It will take a little trial and error to realize that modding this engine is not worth the time and money involved just to make it a mediocre player. Spruce it up and make it nice, but don't expect it to be fast. You will always get killed by Mustangs and LT1/LS1 Camaros, Trans Ams, and Firebirds. Not to mention most of the modern little ricers we all hate. I hate to bum you out, but this is just the truth, and I'll say it again, it takes a lot of $ to make this engine a mediocre player. They are beautiful cars, and that's why I love my RS. Its my daily driver and it serves its purpose well.

 

well I guess I am not really that pissed off about it. The only thing that will make me happy is being able to chirp my tires. I am gonna be getting an aftermarket exhaust system put on (see my thread in exhaust section for more info) and then I am gonna be installing an open element air filter into it to give it some nice added power.

Its a good car, I love the way it drives and yes its not fast but it atleast has decent acceleration. The good thing about this car though is its manueverability, I can easily outhandle my friend's Trans Am in it, I dont know about that 240 though as it seems like it drifts and handles like a train on rails.

I wont dump all my money into it expecting a 300hp monster, but I would like atleast 205hp at the wheels with this thing...
