Thread: how long should a 99 gt last?

if i were to change from regular oil to amsoil and change the oil every 7k miles and keep up with all the maintenance with no more mods than a pcm and gutted airbox what is the life expectancy?

I have 112K on my bone stock GT and it's running strong.

I am sure that 'grandprixfamily' on the other forum (and he might be over here too) has close to 300k on his GT. Should be no problem for the engine, but the tranny is the largest issue I see.

as long as you take care of it, practically forever.

I have a 98 GTP
Have 322224.8 on the same motor and tranny
Just put headers SLP on it this month,
But have been running a 3.4 DHP. well see mods below
for the last 6 mos now and the car is
driving and acting like it just came off the lot...
My car is not a garage queen and is driven every chance
i get this is the first year not driven in the snow...
I have done some body work on it and it will need a new
gas tank and lines sometime this year.
I will be also redoing the top end gaskets just to make sure
everything stays this way.
So i guess bottom line is you look after it it will be there 4 you...

I have 155K on my GT right now....and shes still running strong

They should last for a good while if you maintain them.

It will last a LONG time

My little 3100 has 160,000 miles on it right now and still go'n strong. So yours of you take good care of it should last as long as you own it. The two big things that takes a car down is the trans and rust.

you might wana mention thats KM

I have a 155,000 on my 99 GTP, its been modded since 55,000 (before people scanned and gave a damn about KR at that). It hasn't let me down yet and if it did I could only blame myself. I ran the hell out of it the first few years. I always properly maintained it though. I'd put a 3800 up against any motor as far as realibilty.

I think the 4T65-HDs are damn good as well. Considering the abuse most people here give them, they hold up damn well. I'm still on my original and I think thats due to proper maintance (pan drop every 30,000 miles)...

I have 149K on my 99 GT, it is damn near stock. driven everyday and origonal engine, trans, gaskets, fuel pump, waterpump, alternator, ect. I do think anything has been replaced except the tires, brakes, struts, battery, sparkplugs, wires, and oil.

Holy old therad batman llol
