i own a 99 si and have been battling the turbo or supercharger war. either way i would like to make 300 hp safely on only forged rods and pistons. i plan on running hondata s300 for em. for the super charger- would it be a bad idea to run a jackson racing supercharger at the 6-8 psi, but add pistons with the cp ratio of the ctr or leave the stock b16a2 cp @ 10.5-1. i was wondering if high compression and low boost is better than low compression and high boost-was trying to get away from having to sleeve the block and read that cylinders dont start to move around until about 15 psi. I have tons of questions on this topic but this would be a good place to start. thanks guys!

 

you are going to need more than 8psi from a SC to mke 300whp

your going to be better off going turbo

 

turbo all the way

 

stock internals can handle 300whp fine if the engine is still healthy and your tune is up to par

 

the engine has just under 29,000 original miles and the comperession check comes out at 190 across the board, pedal fully pressed-turned over 5 times. i have heard that if i add any thing to the rotating mass, (crank-rods-pistons) other than stock, it will need to be rebalanced, is this ture? the turbo i was thing about was a precision sc-61 or sc-34. what do you guys think. ive been searching for ever and am trying to figure most things out before i go shopping. all said and done, what is a reasable time i can look at for the dyno and tune, so i can budget some money. thanks in advance!

sc61

 

300 whp with a wide powerband. I'd go with a garrett t3/t04e 50 trim .48 a/r or a gt28RS t3 .63a/r.
