Which LS do you suggest

Im new to the LS world but have been building motors for a while now, Im going to be starting a project soon and was thinking of dropping an LS1 between the fenders and figured I would sign up here because might as well go to the experts. Im slowly reading up on these and have it down to either an LS1 or LS2. I know I could put an LQ9 in but to me that would just be putting a V8 in a car that never came with it, literally I want to say it has an LS1

. My plan is to get a motor/trans(auto) put a cam and supporting parts in it then drop it in. My question is which motor would be better for an occasional driver with track time. So what motor would be best for this, I know Im not giving a lot of info but it will be one of a kind Ill say that much...It will be custom fuel setup and also an aftermarket computer too.

I was also considering boosting it because I will have room for it but dont want to fully build the motor just yet (cant afford that much). Could I get away with puting a turbo/blower on for now and running low boost just to have some fun and when i can afford build the motor or do H/C now and the pull the motor and build/boost it all at once.

Finally are their any good books out their on rebuilding these motors that include torque specs and sizeing of parts. Found a couple on Amazon but if their is a "Holy Grail" of LS motors then Ill get that and read up.

Thanks for any input.

a lq4 is a good motor for boost ,it has lower compression the a lq9. SA design has a good book on rebuilding a ls motor .you can get 5.3 cheap.a ls2 is better then a ls1,except for the intake.
