Help ME understand Third Gen LS Vs. 4th Gen LS
I know my ls1's but know very little 4th gen ls . I want to build up my ls but sometimes i think of purchasing a newer ls crate engine or is it even worth it??
|
Meaning a GENIV, an LS3/L72...
A heads and cam, or even a cam only package LS1 can run really well... |
to switch to a gen4 (ls2, ls3, etc) you will either need to have a shop change the reluctor wheel on the crank, or use the wiring harness adapter to make it work. there is a TON of info on ls1tech regarding gen4 motor swaps, and i believe njspeeder has been researching them as well

but is it worth it? the swap should i work the ls1 or swap then work
|
What are you looking for power wise?
|
well i dont want any restrictions lol thats why i never did anything yet to my car cuz i will get addicted like i did with my lt1 camaro so i want something that i can go crazy on. I know it sounds ridiculous but i would like to have a twin turbo set up. and then a a nx express twin kit set up .
|
In that case... get a GMPP LSX block, some nice forged internals and good heads and your set....
|
if your planning a boosted+nitrous setup you might want to consider building up a forged iron block 6.0 from a truck.....

If you want no restrictions you want a built bottom end. If i personally had an ls1 f body, i would look for an ls2 short block, l92 heads, l76 intake, research my cam choice, and full bolt ons. It would be a couple grand but youd end up with an easy 500 hp with no power adders. As far as worth it? The 4 inch bore affords you a little bit more potential. If your going to swap a motor i would think a genIII compatible ls2 would be your best dolar/power potential ratio |

If you want to upgrade by dropping a GM crate motor in your car you can get a signal adapter for make the 58X signal work with the 24X computer Link here and like someone else mentioned you may need to lengthen a harness wire |
I think your putting the cart before the horse,being that your cars stock I was just start modding. The LS1 has plenty of power potential. If you get to the heads/cam part and feel that isnt enough then I would look into other options.
|
Don't forget that if you want to go twin turbo and Nx you're not only going to need a stronger motor setup, you're looking at the trans, rear, suspension, etc. that will all need upgrading very quickly. At that point the car is going to be so built up it won't be close to a stock 4th gen. You'd probably be better off looking for a car that already has a bunch of stuff changed and leave your car close to stock or sell it.
|
I would invest heavily into making the car better first. Full suspension redo, trans rebuild, everything. Then work on your engine building.

You should set a goal power wise or time wise at the drag strip and determine where you need to be from there. What you've got now can run great. If your serious about boost you're going to have to concentrate on a lot more than your long block.

Op- all the info you need to know can be found here: http://www.ls1tech.com/forums/genera...02-f-body.html There is a company out there that makes all the necessary adapters for the swap found here: http://www.lingenfelter.com/mm5/merc...gory_Code=C162 |

Having done it, it's not that much different from the gen III other than the displacement. It's mostly the same engine. |
