i have an SI head and a LS block but am thinking if its ok to stick with the LS block. what block might u suggest i use,hmmmmmmmmmmm???

 

b20 vtec turbo ftmfw

 

Doesn't matter, once you build the block it'll all be the same.

 

ls vtec boosted!

 

sounds good sounds good but i think i'll just go with the SI setup

use your ls block with a gsr crank and custom rods for a slightly better rod/stroke ratio. also, use 15:1 pistons and a 1 layer headgasket and 20 psi low setting/30 psi high setting with some jet fuel and octane booster and water injection.

youre gonna spend a fortune building a custom engine for boost, so you might as well do it right.

 

 

holy shit iskate... you better do something caude building motors sure better not be one of em.... you need an ibrain to go along with that icraziness....free bump. oh yeah, ls vtec turbo period. a lil more torque is nice just make sure you do it right the first time or you will fuck it up faster then you would ever imagine, and get it tuned!
