Just wondering some LT1 guy's say that an iron block is as strong as the LS1 Motor.I did not know the LS1's were aluminum engine's.Im going to be looking for a LS1 Camaro pretty soon and would like to Mod it to around 420 RWHP plus add a little shot like 75 or a 100 shot of Nitrous.I have heard from some that the LS1's don't live to long on the bottle but I don't know if that mean's the cast stock engine or Block??? Im going to be looking for a 98-02 LS1 Camaro with the M6 and probably add 4.10 Gear's after the mods.Im not going to launch the car from a stand still so the rear end should be safe.This is only going to be a street car so I won't be attempting to many Hole shots.

the rearend wont hold that well. i have an m6 lt1 and i broke 2 stock rearends in a month at the track. also yes all ls motors are aluminum and they love nitrous. my bro has a 99 ta and has sparyed it from the first month after he bought it and it still runs fine.

OLD 69

Im not really going to take it to the track when I get one.I just want a fast street car that runs great,handle's good and gets over 20 MPG.

LaredoZ28

Oh. as long as its street driven i'm sure you will be fine then. The 6 speed tranny's help gas mileage alot. I was getting 26+mpg on my LT with 170k on the motor.

... And I'm guessing you heard that from people who had problems due to an improper setup?

An LS1 can handle a basic nitrous shot (50-150) without any problems when it is properly tuned. There are many people who have run significant amounts of nitrous (6-10 bottle fills a season) on motors that have considerable wear n' tear (100k+).

OLD 69

I thought it was probably due to improper set up like you stated.As far as a power adder I know the LS1's run well with nitrous.I think nitrous is far more popular with the LS1's then running a Turbo kit.At least alot less expensive.

The weak point isn't the block, it is keeping the heads down.

I installed a dry kit on my bro's car and he ran a bottle a month @ 100 shot and when we pulled the motor apart it still looked new even with 151k on the motor.

I may upgrade the head's when I get a Cam swap.Im hoping and looking to find a near stock LS1 Camaro that hasn't been abused to badly and is in good condition.I definately will want the M6 Transmission though.I probably will get a F13 or F14 Cam.I don't care about lack of off idle power as long as its a good reliable car on the street and runs hard starting around 2500 to 3000 RPM'S.

Well the stock aluminum blocks tend to give up around 1000hp, and as the other guy said if you run a lot of boost or nitrous and make a lot of power the heads have a tendency to want to lift. Some people try to fix this buy putting in 1/2 head studs but that gets expensive. The new GM LSX blocks have 6 bolt's per cylinder to fix the problem but you have to find a head that is setup for that combination. But basically you can run heads/cam and a 100shot and probably never have a problem if the tuner isn't a retard.

i'd spray more on an ls1 than an lt1 any day of the week.

ls1's have 6 bolt mains, as opposed to lt1's that only have 2.

The actualy block? yes I'd say the lt1 is stronger. the short block (i'm assuming you are inquiring about the short block) the ls1 is stronger.

Almost any cam will get you 400+ hp with bolt-ons.... I have a small 224/236 cam and I put out over 400 rwhp.

OLD 69

I thought of using Turbo Boost instead of Nitrous when I get an LS1 car.The thing about Turbo's is that the LS1 can't run as much boost as safe as a lower compression 5.0 Turbo Mustang.I know if its tuned perfectly maybe Im wrong.Also it seems that as far as power adders for the LS1, Nitrous is by far more popular.I think I would rather have a non Boosted car because I have 1 already.

You can safely run 5-6 PSI on a bone stock LS1 with tuning and fuel system upgrades which doesn't sound like much when purpose built turbo set ups run 20 or more but 6 PSI can put you into the low 11s at 130mph with a stout rear and a drag tire. I know this for a fact.

Yep. Although unless you just want a turbo to say you have a turbo; it would be much more cost effective to do a head/cam setup and hit it with a 150 shot. Mid 10s should be no problem, and still be cheaper then a 6k turbo setup. IMO

I personally wouldn't mess with a Turbo/Blower unless I wanted 600+ rwhp; but by that point you'll need a built shortblock to handle it anyhow. Not to mention a built rear/tranny/fuel system/etc...

OLD 69

Well if thats true I would rather do Heads, Cam,Header's,4.10's and a Nitrous set up.As long as I can still get 20 MPG with the bigger cam whether bit be a F13 or F14 Cam.This will be an all street car.
