I have a b18a1 I was gonna go with turbo and nitrous but its cheaper to go with just straight nitrous being I already have a kit what all would I have to change in the block to run a 125 or a 150 shot on it I know I would have to change the pistons,rods,rod bearings,main bearings,rings would I have to change the crank or sleeve it I was planning on going with the stock bore figure it would probably be stronger that way if anyone has any answers for me that would be great

 

75

 

Everything you said and sleeves and stainless valves stock crank should be ok. Go direct port run race gas and good ignition upgrade.

 

bigger fuel pump and injector and FPR

 

People have run a 125 shot on the stock block, DP. But it was tuned VERY well. If you plan on keeping the stock block, tunning and getting the right fuel and timming map should be at the top of your list.

Good Luck

thanks for the info
