[LETHALxLS1]

OK you are saying cause you saw a car with 179,ooo miles then they all should last that long?

[LETHALxLS1]

w/transgo shift kit.

no just saying that the the highest milage car i seen that looks great

[LETHALxLS1]

o my bad. Does your tranny need rebuilt?

[greatwhiteZ28]

noo only have 33,000 on car now, but when something does go bad ill probly beef it up

[LETHALxLS1]

I am probably going to sell my car so I went with a stock rebuild with a transgo shift kit but the guy also builds them heavy duty for 2200. Stock rebuilt w/ shift kit was 1400.

*** Funny thing is now I wish I went with the heavy duty cause my car runs so great now I may just keep it. I just put a new ac compressor, wheels/tires and so much other stuff it wouldnt pay to sell it.

[importssuck]

bought the car at 112K
replaced cats, O2 sensors, window motors, headlight motors, ac compressor and many many many little things that add up...and oh yeah the ENGINE! lol
the oil pump went out and the engine blew!
not many have the luck i have but i've spend atleast 5-6K on maintanance work
from MY experience, i'd just pay the extra money now for a low mileage LS1 car

What year LS1?

[danmaross]

2000 ss bought it with 93k and it has almost 96k now

mods are hot cam straight duel bullet exhaust eibach springs and headers

only problem right now is that my window motor is lagging

trans leek got fixed nothing serious

brand new clutch right after i bought it

running amazingly

i've heard stories of guys having to replace their tranny after 50k. and replace various other expensive parts on a low mileage car. nowadays, i don't think 100k is much. it's almost like 200K is the new "100k"

[LETHALxLS1]

I agree^

266,000 on 4 banger now, but still a quart.5 a week leak

[redfiress08]

I bought my 2000 WS6 Trans Am with 78k and the only thing that was serious that got replaced was the transmission and I had to replace two window motors and a headlight motor which was pretty easy. Lucky the guy that owned the car before had to replace the transmission ....... It now has like 79400k

[346ci]

Mine has 133,000 miles rearend went out at 96,000 mi. but was replaced under GM warranty. Other than that it's been running strong, but i think the window motors are on the way out. Very well built cars.

[RIVERRATT]

Mine Has 86000 And Still Runs Like New

[adham]

What year LS1?

2000
just spent another 1200 for a new starter, alternator and battery...got ripped off with labor prices because i broke down in the middle of nowhere

[greatwhiteZ28]

thats all labor , i hope

[astyles]

but my 68 mustang has 350000 miles on it and is still going strong

[adham]

thats all labor , i hope

well that includes the night i spent in the hotel and towing (twice)
i got stuck 4 hours away from where i live and was taken advantage of..
so all the parts were double and probably close to triple their actual costs!

I recommend that you have a professional mechanic thoroughly inspect the car. If the car passes the review, I'd buy it. LS1 engines, if taken care of, will serve their owners well for many, many years and at least 250,000 miles.

(LT1's, on the other hand, are known for Optispark and other failures around the 65,000 mile range, so I wouldn't necessarily recommend buying a high-milage LT1 car if you don't plan on making some investments in repairs.)

If I were to purchase a high-milage LS1, I'd install a transmission cooler and a shift kit as preventatives against transmission failure. I'd also install subframe connectors and a torque arm to strenghten the chassis, and a heavy-duty rear end cover to reinforce the aged rear axle. Lastly, I'd drive and enjoy my new investment, and begin modifying it further as resources and my accountant (I mean wife) allowed.

i came across a sig on a forum ls1tech i think

it said

Mustang= must use supercharger/turbo against Na GM

and its so true lol

oh ya, i got my car at 96k
its got 98k now
no problems, i think it might need a u-joint or trans mount tho.
