View Full Version : power from LS1/LS2



A PSYCHO

hey all,

Im looking at putting an LS1 or LS2 into another model commodore. Basically to do what i want, i would need about 600HP at the flywheel. Which out of these two engines would be best for this power figure, and still be reliable? Also what sort of $$$ would it take to reach this power figure?(keep in mind i cant boost it, and cant stroke more than 411ci).

Also can the T56 manual box handle this power from factory? Or would it need a little work?

Bit of a no brainer really. LS2 is bigger so it will get the power easier.

To build a 600FWHP LS2.
Say $4000 for a motor.
$3000 Heads and Cam (a big one)
$1000 for injectors and other associated bits to pull down and put it back together.
$1000 for tuning.

Total $9000 but thats a minimum and only if you do all the work yourself.

Yep a T56 will handle that no worries.

I was told that the LS1 has some advantages the LS2 doesnt, but i still thought the LS2 would be a better option. But this would also depend on the price difference between the two motors.

For example a cheaper LS1 with work may come out cheaper than expensive LS2 with work, and both make the same power. Or do you think the LS2 will still be best bang for buck to make that power figure?

LS1 - 346CI
LS2 - 364CI

Always going to be easier with an LS2

Do you need to build from scatch, or can you use a second hand motor?

The LS1 in my VX is making around 550-600bhp at the fly wheel. Its been stroked to 383 (6.3L) with forged internals, cam, exhaust, MAFless tune etc.

Very street friendly, very even power delivery. Being a stroked engine its making a lot of torque across the rev range.

Of course stroking a LS1 can cost upwards of $10k depending whos doing it, what parts are used etc....

So you might get lucky and be able to purchase one second hand.

Otherwise, any reason you cant go a L98/LS3? With a cam, exhaust, tune you'll be making plenty of power...

Either way we'll need pics of whatever you put it in to :)
Either

A second hand setup is deffinantly an option, in fact id prefer it as that would keep costs down. Mind if i ask who done you LS1 stroker and what it cost? PM me if you like.

Main reason for not going LS3 is because of cost, and availabliltyor lack of i should say.

Do all the LS1/2/3 ect ect all use an alloy block? Main reason, the car will be setup with drag being the main concern, so lighter = better.

yes all alloy blocks, there are also cast iron blocks too which are good for forced induction monster hp setups where weight isnt such a concern.

Oh Matt, what are we going to do with you :p

If you want to go with this route, then i know of a 408ci stroker you can get for about $10k ;)

If it's the same one I'm thinking of, that'd be an iron block. Probably not the best idea if keeping weight down is a priority. :)

^^^ Came out of a GTO coupe???

Yea, i know alloy is lighter, but honestly, he wants it for drag racing, and at the times he is looking to run, i dont think it will make that much of a difference.

What times is he looking to run with a manual box ?

LS3 stroked with the right cam. That would be my pick. Go high comp if you can and if racing E85.

Dont know about with a manual box, but i know when we were talking last night, he was talking about building a car that will run 9's.

What sort of weight different is there?

As said IDEALLY high 9's/low 10's. I would prefer something like a powerglide ect, and was told the factory auto's will not like that kind of power. Any recommendations for a box then?


p.s. 55ZVZ you really dont think ill ever do it do you? :p

wouldnt a stroked ls3 be over 411ci?

Also why cant you boost it or be over 411ci, build a stroker with forged internals then NOS it

I cant boost it or go over 411ci as thats what the laws in QLD state. Same with NOS, not allowed it in any way, shape or form.

this is all to remain registered.

thanks for the links guys.

Can anyone tell me if this powrglide would bolt up to an LS2? Would it need an adapter plate or anything? Is it a decent price?

damn, i cant post links yet not enough posts. Well go onto ebay.com.au and search for:

"v8 powerglide automatic transmission trans-brake"

I'd be looking at an L98 to start with ... cheaper to buy than an LS2 and still a strong engine. Much better heads than an LS1 or LS2.

Then go a GM Motorsports turbo killer cam, pushrods, valve springs. That should get you well over the 500HP mark. You can spend another $2600-2800 and add some Higgins heads ... but the L98 heads are already so good you will only pick up around 20HP from what I have been told.

For serious horsepower look at a GenTT system. I believe they have achieved well over 600hp in the past with this combination in a VE SS.

PM Street Tuna in this forum - he can give you the details.

The first post indicates no boost.

I thought the L98 was an LS2 haha. Or are they just the same dispacement? Also as siad, no boost allowed sadly.

Is there anywhere that sells pre-built crate engines? Or am i going to have to buy a bog stocker and build it somewhere else?

They haven't been that cheap for awhile, but some are still available. L76's are available at Corio Auto Parts (Geelong) for $4100. These will need different lifters and a different valley plate, but other than that they are pretty well the same as L98's. I expect you would be changing these items regardless of the option you choose, so it shouldn't be a big deal.

p.s. 55ZVZ you really dont think ill ever do it do you? :pI never said you wont do it, but for a budget of $25k, i dont think you will run reliable 9's :p

As i said to you, LSx is a easier way to go, if you want big reliable power. Dont worry to much about Nitrous. If you want 9's, i would suggest running Nitrous on the car. It will be easier and cheaper to achieve this with the help of giggle gas ;)

You just connect it up when you go to Willowbank and take it out when you leave.

Oh, and remember what i said about a cage, seat, harness, ect. Unless you want 1 run, and 1 run only, you will need all the proper safety gear, otherwise you will get the boot from the track.

checked them out, and they dont supply any LS2, LS3 or L98 motors. Do Holden still supply brand new motors? I know someone who gets a discount on parts at a dealership, but Holden usually mark up their prices so much, even with a discount someone like Holmart might still be cheaper.

may have found an engine builder, discussing options now but sounding like an LS2 block with other goodies. Will wait and see what he recomends ect.
