You should be able to hit your 300whp goal. But those injectors are going to have a really high duty cycle. I would go ahead and get bigger injectors.

 

yea definetly get bigger injectors. but as far as number you should be able to surpass 300whp pretty easily. I made 343whp on a stock bottom end and a mild built head. also had 550cc dsm injectors.

Honestly if i had your setup i would aim for 400whp. just replace the injectors. U taking it to cft for tuning?

 

BOSCH 750's talk to Tony palo about ordering some. and get ur self a walbro 255hp
