I have a s5 std motor it is out of the car wating for a microtech computer and i would like to make 300rwhp or around that just enoth to beet the subarus. however this is a daily drived car so it needs to be 100% reliable
i have been looking at a bosch 910 gas pump and 1000cc secondary injectors. my planes are to waild two s4 intercoolers together and use them up front
what other mods and boost level would i need



A Big Frickin Turbo - Over steer is when the passengers are scared, under steer is when the driver is scared

 

I have (2) 1000cc injectors for sale. They were originally stock S5 injectors, but I sent them to www.RCENG.com to have them bore it out to 1000cc. That means they bolt right up to your S5 with no modification at all! They have never been used. It cost me $175 to bore out EACH injector. That means i paid $350 for both injectors. I'm willing to sell $200 for BOTH. Reason I'm selling is because my hp goals have gone up, and 1000cc is not enough fuel.

BTW, to make 300rwhp, you would need a free-flowing, turbo-back exhaust. Also, you can make 300rwhp off a hybrid turbo (upgrade compressor/stock hotside). A T04B or T04E would be a great choice.
