Never. It really needs to have a fluid flush, though. He said when he checked the level the fluid was chunky??????? That really scared me. I don't know how old fluid would slow his car down, though. I'm positive it wasn't slipping.
And another thing, the Series II N/A have way more low end than anyone gives them credit for. Here'* the torque curve for the Series III N/A 3800, which is almost identical to the Series II torque curve.

By 3500 rpm, the L36 is making 150 hp and should be kicking the crap out of your LN9. At about 1500 rpm, it'* making 215 lb-ft. of torque, which is ALMOST equivalant to the LN9.
The L36 is like an LN9 that holds on to the powerband for about 1000 more rpm.
And I did notice how it seemed 50-70 was quick considering how slow his car was to 25 mph. I really can't figure that one out. If you were in his car, you'd realize just how slow a launch is. He was in my driveway once and I didn't believe that he couldn't spin his tires with the e-brake on, so he got into his car, put the e-brake on all the way, and floored his car. It just moved foreward a few feet, dragging the rear tires. It didn't even squeek a little. I had to admit at that point his car was slow.

I was thinking that a new O2 sensor might wake up his car (he says he gets bad fuel economy, too). I'd like for him to put a new one on, because I'm almost positive that his old one is original, but he can't afford a new one and I'm not going to buy one for him, so his car will remain with the original sensor. His birthday is coming up soon, though.
I just don't want to have him buy an O2 sensor and then have it make no difference.

I have said it a million times... 2.84 is some heavy gearing for the L36 or an 3800 if you ask me... I have an L36 and do respect it... I love the way it will run to the red happily... But its going to be a bit slow off the line... with the 2.84 gears it will pull as the 3800 gets up into the rev band...
And his car may just be sick... The 94-96 O2'* seem to be good for 50,000-70,000 miles... after that they do seem to get lazy, and the PCM won't see this as an issue untill the sensor is almost dead..
also does he have the Stock cat?

No, he got a new cat because he had no power, and he has an aftermarket exhaust pipe, but i'm not sure what brand it is. They're both welded in the stock location using the stock pipes, so it'* not like there'* not enough restriction on the car.

As an update:
He previously had the E-Bay Special CAI on his car. I figured it wasn't helping his speed any, so we came up with a plan to block out all hot air. His tube was 3 inches, then there was a blue silicone 3" to 3 1/2" adaptor, so the steel tube fit through the stock air box hole. Well, I gutted his stick air box (including opening up the computer side of the front and removing some of the computer insulation.) After, we put his CAI and filter inside the stock air box, so it would suck cool air from inside the box. It took a little bit of facny work to get everything settled properly, but it really helped.
Low end pull (0-25 mph) is about as much a high end pull (50-70 mph). I knew his intake was slowing him down, I just didn't think that it would make that much of a differance. It feels like he has a new car.
Lesson learned. Hot air means slow car. Really slow car.
I just flushed his trans, too, so now it'* shifting smooth as silk. All that needs to be done now is an O2 sensor and Seafoam cleaning.
