I know that.....So if you where to put an N/A motor with the higher 2.93 gears then technically you should be able to increase the mileage but would this lug the engine and cause worse mileage?

No. The 2.93 is going to have lower rpms in overdrive.

Yes I know that's why I was asking if it is going to lug the engine.......

It's not going to "lug" the engine.

2.93 to 3.29 isn't a huge difference. You probably wouldn't even feel it, but for the cost, the swap isn't worth it. You can get hpt and write a more fuel efficient tune and save the trouble and money.

My trans is missing 4th and has close to 200K so I was planning on getting a tranny from the junkyard and rebuilding it so if I can get one with a little higher gear ratio I may as well

You'll have to tune for the ratio change anyway, so don't forget to add that into your cost.

I think 2.93's on top of the na with a tune would get you the best gas mileage you could get from a grand prix unless you put a 2.86 in it but that would be a very minimal change from the 2.93's

Yeah I would tune for the mileage and the gear change at the same time. What will be effected without tuning for the gear change beside the speedometer.

it won't shift right

VSS would be off and it would go into limp mode.

Is tuning something easily done by yourself if I where to buy HP tuners or would i be better off going to a shop to get a tune or paying a member on here to do it?

I could do it. I'm about 2.5-3 hours from Indy. $50 is all it'll take

For a mileage tune & for the gear ratio change? That would be great. Would i be able to send you my PCM since i can't drive it with the HD gears until it's changed?

I'd have to have the car here. You'd be able to drive it it just wouldn't shift right

Alright. I'll PM you once I have the tranny in so we can figure out a date and time. Probably will be some time in the spring.

Ah. So you want the CEO's of GM/Ford/Whatever to pull the money out of states themselves? Because that's what's been happening for a long while now. None of those American corporations really give a **** about America.

And it annoys the hell out of me when people like you think it's more important for a handful of CEOs and higher up sales/marketing/management people to make 6+ digit incomes for American car companies as opposed to import companies giving assembly/manufacturing/etc jobs to thousands upon thousands of average Americans instead. You'd rather see filthy rich people who have all sorts of ways to "write off" taxes keep the "profits" in the US as opposed to employing tons of blue collared workers like those "no good" import companies do?

I'd rather see the cars built here because at least the money is going to workers. It's the jobs that matter to me, not who the corporation is really. Once those profits go in their pockets, it stays there, it doesn't really matter what country they're from.
