I have a B18C5 stock block with built head. Crower dual valve springs, ti retainers, manley valves & bronze guides. Now I want to upgrade my fuel delivery but not sure what route to go. Walbro 190? should i get bigger fuel injectors? I would like to go 10K here and there. LMK THANKS!

stock injectors are good for ~190whp. a little more if you bump the pressure. but this is not a good way of doing it. base you injector size off hp you plan to make.

So you have a stock motor with springs and retainers? No more compression? No big cams?

If so, then what you have is fine because you are still making stock power. If you rev that to 10k, you are just making a lot of noise. It will stop making power at about 8200 or so most likely.

I see, what would you guys recommend that I look into next?

Cams would be my next step along with a nice header and exhaust. That will pick it up a good bit.

10k RPM?????????????? lol

youre going to be back later and post why you have spun rod bearings.

310 or 370 injectors would be good all motor. Make sure you have a system to tune those into. Like crome or hondata and a chipped ecu. You will need one anyway to adjust for cams.

I plan on running s2pro1's but don't know where rev limit will be set to until I get on the dyno and see where the power falls off.
