I heard that you cant rev the ls/vtec high, because the bottem end cant handle it, but my question is, how can I make it handle a higher rev point?

 

internal build up, pistons, rods, cams, cam gears everything

 

do you mean, turbo pistons, and rods like JE Pistons? what type of cams? and gears?

 

get your crank/rods/pistons balanced, then get a block girdle...arp rod bolts...aftermarket valvesprings/cams combo that can take the amount of rpm that you want...basically, you have to build a motor that will be able to take the beating of higher revs and compression.

 

push on the gas pedal harder

 

buy a chipped ecu with no rev limiter and blow your engine sky high or build it with good parts head work also work on the bottom. Always remember cheap parts aren't good and good part aren't cheap.

 

better rob bolts is the best way when ur strapped for coin, because thats one of the main things that screw up, the bolt streches and ur done....

 

Rod bolts for stock rods (or a good set of rods), gsr main girdle ( or z10 ), block guard ( or get it sleeved ), and thats just a start with the block.

Then you probably already know what to do with the head.
