How much moding would be needed to fit an LS3 into my 2002 SS?

 

It will bolt right in, but you need an LS3 ECU, wire harness and a dyno tune. It would be cheaper and you will get more HP by just doing a headsw, cam, intake on your current LS1.

 

the ls3 is a modified ls2 isnt it? or is the cid different? i just know they changed from the ls2 to ls3 in the new vettes recently, but not sure what the difference was other than like 30hp or something

 

Do some initial homework first...

so its a bored out ls2 in effect. bageezus u could have just typed that. not all of us exist on this forum for the sole purposeof posting 3 links a day from whatever random net surfing we happen to be doing.

u would have saved urself energy to just say "its a 6.2L"

 

may i ask why you want to do such a thing? for the cost of that swap you could have a wicked LS1.

 

[align=left]Ok... I've done some homework... I've picked out a few beyond bolt-on parts for my LS1. I don't have a garage to work in or the "know how" to do some of the mods that i would like to do. So I had to call around for some prices of shops and-what-not. and I added it all up to be over 12G's!!!
Is that price right?

Mods picked out + Prices;

Fast LSX 78mm intake manifold: 809.99
Fast LSX 78mm Throttle body: 464.99
LSX Fuel Rails (looks): 232.99
SLP Air induction Kit: 312.99
SLP 85mm MAS: 196.99
SLP Under Drive Pully: 252.99
MSD Tune-up kit: 827.99
MSD Ignition 6+: 319.99
ECT.

I don't mind paying, just as long as it is done right and the motor is still reliable. thats why i didnt go to big with the cam, intake, ect that i picked out.

i wouldnt pay that much for those parts.................. holy crap. ur talking about 3/4 cost is just install thats not right.

 

Notice the ECT. at the end of the list? That means the list is incompleted.

 

If you like I could have put EVERYTHING that i am going to to to my car on here. I just didn't want to take up to much space so i paraphrased the list.
