    LS1 vs LS2

    I am in the market for a Vette. I am not too familiar with the LS2. I am wondering should I save the money and get a pre- 05 vette or should I get the 05 up model. Is the power worth it? What about stock tuning issues etc? I am very familiar with the LS1 so I lean toward that but if the Ls2 is more of a beast... I just don't know. I have never driven an LS2 powered car so I personally dont know. I have seen LS2 powered cars run 13's at the track(what my LS1 ran stock 13.50's). Thoughts and experiences please.

    Money isn't the issue. Why go with the LS2? What is the performance vs the LS1? I know 400hp factory rated etc. I am talking rwhp and 1/4 track times / mph

    Big positive is it (LS2) has more cubes. That goes a long way when modding. Basically though, the LS1 and LS2 are built on the same architecture with only, really, minor differences. But I read an article of just a cam swap on an LS2 and it gave it an extra 90hp at the crank. It was in GMHTP mag.

    If you go with C5 go with a Z06. The C6 is much faster than a base C5. I drove a C6 Z51 and loved it. If I had the money I would have bought it. By far the best car that I have drove. The LS2 is already 50 horse ahead of the LS1 and you can do all the same stuff to it to get more power.

    Get the LS2 vette if you can afford it. it would be much better for you in the long run if you are looking to modify it. check out all the new GM performance parts. you can snag some l92 heads and an l76 intake manifold which my room mate just got in the mail today for under 1500$ and you are talking about a combo that outflows any aftermarket setup on the market for a fraction of the cost. you can spend 2,000$ in parts and have a 500rwhp C6... With the LS1 it is also possible but you are lacking displacement, if you wanted heads that flowed as well as a set of 800$ L92s then you would have to spend 3,000$ on some AFRs.. just an example. GM has just flooded the market with performance options for the LS2

    go with the ls2....everyone is right, more cubes, newer, and hey, its a c6.
    its kind of like deciding whether to go lt1 or ls1 a few years ago (kinda). you like one, but the other is newer, more powerful and seems to make more sense. oh and then theres a little thing called a warranty. and 100,000 cant be beat, unless you want a hyundai.....

    For the simple fact that THERE IS NO SUBSITUTE FOR CUBIC INCHES!!

    In my experiance they (LS2's) are alot more fun to drive on the street. The tq gain through out the power band is AWSOME!!
    Thats with real tires not stock radials.
    I'll say your looking at 3-4 tenths at least.
    I've also found the LS2 likes more bottle also.
    The power curve is alot more steady vs. the 5.7 is more like a spike. Hard to explain in words on the computer.
    I would blow off 10's all day with the LS2 and 11.30's in the LS1 to throw you some #'s.
    Thats my 2 cents..


    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    Ls2tuner, juiced99 thanks for the insight. What do you see the Ls2's lay down in rwhp numbers. Tuner, I know exactly what you mean by the "spike" in an Ls1. Look at my tq. numbers on a 125 shot and simple bolt ons. The best Ls1 numbers on a stock car i ever saw on a chasis dyno was 326 rwhp on a bone stock 2001 T.A. An old guy brought it to my buddy's shop and saw the dy no and wanted to try it out (he knew nothing about cars). I remember he said "IS that pretty good?" All of us were like man whenever you sell that car call us. Anyway, sorry to get off topic.
