I'm getting ready to buy a rebuilt stock port 13BT, and will be putting it in my FB. Since I'm doing the swap, I figured I'd really make it something. The engine comes with everything to make it run like a stock S5 TII, down to the transmission, harnesses, and ECU. So it's more a question of what else?

I'll also be getting 800cc and 1600cc injectors.

From there, it's all on me. I have a $5,000 budget for a new turbo, manifold, fuel delivery system, fuel management, FMIC, ignition and everything else.

With that money, is 330 HP too much to ask of a stock block?

 

I'd say definitely do-able givin it's in good condition, or do you plan on rebuilding it, but just stock?

 

He said it is already rebuilt.

And yes i think 300+hp is doable with a $5000 budget. The block will hold up to 400hp without studding and all that $$$. You will need to run higher boost and get meth and a big IC to get those numbers without a port job but it can be done.

 

they do 330ish on hybrid turbos in japan all the time
