LQ4/LQ9 engines...

is there any reason why you dont want to mod your ls1??

i would understand if you wanted a 402/408 or are going boost down the line and you wanted the iron block BUT i wouldnt want the added weight of the iron block just to do a cam and some head porting.... just something to think about

**98maro** · 06-23-2011, 11:02 AM

The reason why I can't mod my ls1 is because here in Cali. Emissions sux.
I want my ls1 completely stock in Case I need to swap it for smog inspection or something
I don't think I'm goin for stroker kit anymore. Unless I get a cheap kit. Which I don't think that could happen.
I was thinking on getting an ls1 or ls6 and mod it.
But those blocks are more expensive in my are than the 6.0.
Plus I heard people saying that ls1 blocks can crack after high mileage.

How heavier the lq9 are? I mean. Weight difference

Any good advice welcome pls

What block should be good for my goal?
I'm trying to go over 400-450 hp.

you can get 450hp out of a ls1 without a problem

there about 100lbs heavier (i think) cant remember off hand

Damn it. That's a huge difference.

How about the ls2?

I'll keep looking around. And see what I can find.

The iron block weighs 87 lbs more, but you can easily overcome that weight by going with a slightly larger can since the larger cubes will tame down a larger cam. Plus with larger cubes your torque comes in earlier than a smaller engine, so say you can have a win win here.

Plus you might want to think about buying another computer for your car, so you can lol(smog swap ) your engine and computer the weekend before you get it tested and you won't have to get it returned every time.

I kinda want more the 6.0 sounds better than 5.7 lol
87 pounds is lot of weight. But I'm sure is a better motor.
But I'm doin the weight redution anyway so I should be even.

I was thinking on a second PCM.
But I was told the PCM holds the mileage of the odometer right?
That could be a problem.lol

ill take the lighter car over the "bigger cam"

theres not that much of a power diff to make up the weight..... just my take

This is when I get confused.
You got a good point too.

6.0 is heavier but more cubic inches motor and it's a better motor I believe.

Ls1/6 are lighter engines,
But I don't knw if it could mane the same hp as the 6.0s.
I'm confused

5.7 - 6.0

oh yea HUGH diff lol

being better shouldnt matter to you bc you are not pushing the limits of either engine, there are people using LS1 blocks making 700rwhp on boost

Meanig broken piston, bearing or stuff like that

ummm yea, i wouldnt do that lol the block could be fucked up and or need alot of machine work

Just get HPtuners, then save your stock profile, and create a new one for the 6.0... swap tunes with motors.... or just cam and spray the ls1 and save alot of time and effort.

**98maro** · 06-23-2011, 04:09 PM

now im debating on ls1 or 6.0..whatever find first thats what ill get, and for a good price too

juice is on my list for sure... but on my stock motor dont have trust for nitrous lol....

my plan...
ls6 intake
ls2 chain
ported heads (243s i think.not sure yet)
LTs
custom y pipe, or true duals, with highflow cats..
non-california smog legal cam...LOL...
ls6 ported oil pump.

hopefully i can reach more than 400 hp..
im gonna start buying pieces already...

the stock 6.0 can only take about a 150 shot safely.... more can be had but its not worth the chance

both can make that power without question, just the LQ block will be 100lbs more lol for what your wanting to do i dont see no reason in getting a 6.0.... just my .02

good luck

thanks bro.. i pareciate the help..
i think ill just go for a stock ls1 and do the samething..
80-100 pounds make the difference on a 1/4 mile.. if both engines can take me to the same rout i dont see the point on getting a 6.0...
unlees i make up my mind on going for turbo or something..

75 shot is safe on ls1 right?
