  • Welcome to Forever Pontiac

    We are a community of Pontiac enthusiasts. The purpose of our community is to keep alive the Pontiac spirit by sharing (or showing off) our cars, discussing Pontiac, helping each other work on our cars and find information, plus attend various meets/shows/etc... To aid discussion, sharing, event planning and selling of parts/cars/anything, we have various parts of the website to aid this from Forums to an online Garage to Classifieds to even a Document Download Repository. You can find links to these in our navigation above based on what each section helps with (discussion, local events, learning, etc...).

    We invite you to contribute, find help or just view some of our member's amazing cars! Don't forget, we also have great contests from time to time (like our Pontiac of the Month and yearly calendar contest) and our Pontiac This OR That, a fun game where you choose the best of two randomly selected Pontiacs from our online garage.

    We look forward to seeing you around!

I put new headlamp assmebleys on, i went with "stock" replacements because i believe they still look hot.

I also have new adjustable fog lamp assembleys to put on just havent had the time.



I put in a CAI and have noticed quite a bit of difference in power and less fuel consumption.

I just had my car in the shop, some of you may remember my topic on blue smoke, we found the problem, the valve guides are bad, so as soon as i can get my hands on another pontiac she will be put in my garage and i will either swap the engines or do a complete rebuild. Not sure yet.

Valve guides are common in these 60*V6 pushrod engines, but considering its age, replacing the engine altogether may be a better option.

The L82 isn't exactly modern, but you can swap in either an LA1 or LX9 engine. I would consider replacing the transmission as well, the trans from a GAGT, the 4T45E would probably work best because of the more aggressive gearing.

LA1:

175HP

205TQ

LX9:

200HP

215TQ

The LX9 is a better engine, better LIM design and makes more power, as well as being more responsive to bolt on mods and tuning.

Either way, you'd need to save up a decent amount, I'd plan on saving at least $3.5K for the swap.

I'm not 100% sure with the 4th gens, you may be able to reflash the existing PCM with the needed fuel mapping and such. In essence, the LX9 is not that drastically different than the L82 and LA1 it replaced.

1) Not a cold air intake, it's just filter and would be considered a warm air intake, if anything

2) No horsepower gains will be had with that. You MIGHT experience a microscopic improvement in throttle response at best. But it's all in your mind, you think it's helping, but in reality it isn't

3) Fuel economy hasn't improved at all. Maybe you just haven't hit any additional hills than usual. But just like the horsepower, all in your mind.

This car does kind of bring back memories from 10 years ago when I had my 97. Man time flies.

Sam, I still remember it like it was yesterday when you had your 97 coupe.

Good times with that car. It was such a riced out pile of crap, but man I learned a lot about cars from it.

I got that hood for free. When you are 18 and someone gives you free stuff for a grand am, you don't say no! Haha
