ej25t_BLITZEN

Hi there all im new here, I have been getting a EJ25T build from ground full forged internals, blue printed, balanced (0.5g), ported polished etc this is a semi closed deck 2.5L engine capable of exces of 700hp. Just wanting to see your guys views on what turbo, extractors, wastegate and intercooler selection. Still dont know if want it front mount or top also am aiming for 500hp so correct turbo is going to be a biggy. Dont want to go overkill but still want to make at least 500 horses. I appreciate anyone that can be of help Cheers
