Do you mean S54?

No, I figured the S52 would be cheaper and easier to find.

To the people that say no to an LS engine "cause everybody has done it". There is a reason. Great motor, small package, bang for the buck.

Let's get a list of all motors suggested, with Price (including wiring/ECU) Hp/Tq ratings and if you can find it, weight fully dressed with accessories. Let the numbers decide. So far this is just the Chevy V8 guys VS. the "NO Chevy bad" guys putting up arguments that I haven't seen backed by facts for both sides (in the same argument). And I'm just as guilty as anyone. To me this is the smart way. Make a list comparing all the important features. Maybe we should inlude aftermarket support and power potential as well? But those can be slightly subjective. Also tunning! GM's can be flashed easy. Some of the older stuff is going to depend on other more expensive solutions.

The 2JZ is very heavy. You put in alum V8s that weigh less. If you want to do it on the cheap, then do an earlier 2JZGE, instead of the GTE. But I think one of your main concerns should be what affordable tranny with bolt up easy to whichever motor you go with. There are a few tranny options for the 2JZ, but non are close to cheap. It depends if you are looking for 300hp or 1000hp though.

[4g63tcrazy]

1000hp or bust! :guns:

[Shane@DBPerformance]

Will his Z chassis even handle any power.

[JET]

I think 700whp is pretty rediculous if you want it to handle also. I have the LQ4 (325hp) in our Denali XL. It is pretty amazing how well it hauls around over 5,000 lbs, it scoots pretty good. I think if you got an LS2 with bolt ons and put out 500+whp, you would be happy in a light car. NA would be good for the twisty tracks too. If you decide that isn't enough you can always turbo it later.

Here is a good option:

[turbotalon1g]

^That is pretty much the plan sir.
I thought that by adding boost I wouldn't lose the NA power that would be perfect for Auto-x type stuff.
I do plan to boost it later on.
I think JET, RYAN, FLOPPY have said it perfectly and right now the major choice is between the LQ9 and LS1/2.
The Z chassis will need some work to hold this power, but the aftermarket for handling is sweet.

I dont know about that jet my man, thats a ton of money. I know someone with an LS6 pull out from a C5 Zo6 might see how much he wants for that.

The iron can handle power without being built, but the aluminum not so much. It would be tapped with heads/cam and maybe 50-100shot.

The yellow Z with an LQ4 formerly owned by titanium a local on MNSC sold to a guy 4 hours away in WI, I am talking to him now and might go get a ride in it.
I started a thread over there and an admin/shop owner said its up to you and what you feel and locked it right away so yeah.

I thank everyone for the helpful input. Remember I am not baller, I usually end up sacrificing food and clothes to work/fund my car.

The LS1 blocks were much weaker than the LS2 blocks. LS2 blocks are taking 300hp shots of nitrous and have made over 900whp. I wouldn't do the LS6, the LS2 is much better. Look for a later model GTO or that vette place by us on 65.

I was pretty much the only one who said it blatantly, so you can call me out on it. :D

It's just personal preference; opinion as some would say. I don't deny it is a good package and bang for the buck, but he did mention that he wanted something a little different.
