I got a civic hb, i got an ls motor for it,was wondering how much pounds it could handle if i build the bottom end with eagle rods,cp low comp pistons for turbo,block guard,and the head just do valves springs and retainder and vlaves maybe supertech and ferrea, so how much can the block handle?

 

i can give you a guesstimate but thats a really broad answer...it all depends on your turbo setup and how much boost you want to run....i wouls say with the guards probably 25-30lbs....it all depends on your tune also...how much hp you lookin to shoot for? i would get turbo cams as well

 

hahahahaha 25-30 pounds? funny. ls with pistons and rods and a block guard all depends on the size of ur turbo but saying u used an average size turbo maybe 14 pounds sayely mayb 16 with a good tune. ide say even 18 pounds but inot the 20's nah get some sleeeves and build it up a lil then u can see into the 20's

 

and turbo cams... waste of money. i know ur running an ls but ive seen gsr's running stock cams making over 600whp. if ur doing a simple build do ur pistons, rods, rod bolts, block guard and get a good turbo setup. wats the point of doing the valves and springs and retainers r u planning on bringing the head to higher rpms? ide put the money into the turbo setup rather than the head. just me though. get a walbro fuel pump and definatly get a good tune.

 

i would want some quick spooling turbo, maybe t3/t4 ,what u guys think,looking to pull out 400 hp

 

I think a gt30r (.82ar for the top end if you mod you head) would be a good 400hp turbo, just shop around.

 

T3 60-1 would fit your needs.
