Hi guys ,

I have had my ls1 for 2 years now and a lt1 camaro before that for 10years .
so I am no newbie to camaros but I am to the ls1 motor it self .
usually I find all info by searching . could not find this one . really appreciate your help .

My ls1 has 60K miles on it and I wanna do a preventive bottom end refresh .
I read some horror stories about the stock con rods bolts etc . ohh I live on a island with no acces to a decent machine shop . I have a lot of experience with building race motorcycle engines .

what do you guys recommend for rebuilding the bottom end ?
I would not mind buying forged rods but I have no way to balance my crank .
are there rods out there I can use on the stock crank .

please help me out guys

appreciate it

thx

what are your plans? ls1 stock bottom ends are pretty strong.

kawaking

I wanna keep it stock . but I just want to make sure it is fresh with new bearings etc .
put a new oil pump etc so I can keep on beating on it . hahaha

kawaking

the car has what I think is good oil pressure around 50 on start up
40 when really hot WOT 60 if oil is really hot .
engine sounds good but I wanna keep it that way .

if its fine and no mods are planned id leave it aLONE but none of us ever do.

I wanna use a 100shot of nitrous maybe . i really wanna fresh it up

If this is of any help to you man, with 60k, there is no point in refreshing anything right now if there is nothing wrong with your bottom end. There are people on here with 100k+ on their stock bottom end that race/beat on their car regularly and they have no major issues. Also, with a good tune, the right spark plugs and proper fueling, a 100 shot of nitrous is completely safe for your stock bottom end, some people even run 150, hell some push it even farther and still do fine.

Ok ok thats comforting news . guess I am a wee bit paranoid i change my oil regularly with synthetic oil so i think i should be fine !

You should be fine even with a 100 shot. If your going to be turning high RPM's and its a early LS1 maybe consider some ARP rod bolts. Just do a tune up with good stuff and rock and roll

from stock to 100 shot lol.


but yes a 100 shot is safe but you might need to upgrade some stuff if you want traction ect. i wouldnt trust a stock clutch or a4 running spray.

kawaking

I have ls7 clutch thats fresh i put in there like 6 months ago , ticks mastercylinder ,flowtech longtube headers, 3inch cutout ,gm hotcam, lid,hardend pushrods. mail order tune from pcm4less
i think thats it . is the rebuild making more sense now ? Lol gahaha

Now we're getting more details on what has all been done but still IMO your
completely wasting time and money by messing with the lower end. As some
have stated perhaps rod bolt change which many argue requires rehoning the
big end for oversized(.002") bearings and others state just remove one at a
time, oil on the threads, extreme pressure lube under the head, retorque, and
move on. Guess that could require some research and ultimately flippin a coin.
Plenty magazines have taken junkyard (unknown miles) LS engines and made
600 plus horsepower with power adders and no lower end issues at all.
I've spoken to people who had a new engine ready to go and literally tried
killing their stock LS with 200-250 shots of NOS and couldn't. Just trying to
save ya some time and money.

Imo its not worth to rebuild a ls1 with all the other great options out there, imo roll what ya got and build a motor on the side

^ I agree run the LS1 and build a 402 for when it goes.

kawaking

Thats sounds like a great idea . so i gotto start looking at the lq9 's ?
Whats the right combo for that ? Stock bottom with better heads and a cam ?

Or find an LS3 and do cam only......done

depends on your budget and what you want.

im very happy with my ls2 setup.

I would go ls3 and do a cam and call it a day as someone else suggested, tsp also has some pretty good deal on motors, it just depends on what ya want n budget

kawaking

The island I live on is very small. the ls1 has more then enough power .
I just want to keep it going strong it dynoed at 350hp at the wheels

Thats why i want to keep a stock bottom end

youll get 350rw on a dyno jet without even touching your internals. but youll want more.
