Has anyone on here gotten 300-400hp with a boosted LS motor with stock head and sleeves?
I plan to build the bottom end... rods, bearings, pistons, clips, head gasket, arp head studs...
Do you think with the stock sleeves and stock head 350+ hp can be reached on a good tune, and still be reliable?

 

buy cams

 

Xenocron hit the 300 mark on his stock block b18a1 I think it was. A built B should take even more abuse, but like he said^^^...cams.

 

very possible. with a good tune and turbo you can get to 300.

 

its an LS
350 whp is easy with an LS with rods/pistons/head studs/cams/and a good sized t3/t4, or maybe an sc61, or even a gt35R if your a baller....

 

hell yeah, thanks for all the info.

Im going to shoot for 350-400 on stock sleeves.

 

he said vtec killer cams not killer vtec cams lol.

 

You can do 400 on stock head (and cams) and sleeves with forgings, but it's going to require race gas. I recommend getting Delta regrinds for silly cheap, they really do help spool and powerband and peak power.

The dirty secret of xenocron's LS engine is he got it used and suspects it might have cams already since it had a lot of high dollar ---- bolted to it and to the car it was salvaged out of.
