hey i am looking to turbocharge my mustang... its a 96 and has very high miles. i no i will have to rebuild the car and plan to do so before the turbo goes on.. Problem is im new to the 4.6 and there are alot of ppl that have the 5.0 but they dont have any parts and are not very familiar with my 4.6. i need some input on where i can find some resonable PI heads. what would be a good cam to run.

i want to run 10 to 12 pounds of boost and keep the car a weekend warrior/run the track a few times. Will the block be ok for this kind of abuse? and what are some good pistons and rods?

Just with the turbo,heads,and cams will it be possible to hit 4oo horse?
any help will be greatly appreciated

At 400, your block, crank, pistons, and rods should be strong enough, as should your transmission. Every car can benefit from some stiffening, but even that's not critical yet.

And yes, 400 is definitely achievable with that setup, and 10 to 12 pounds should get you there. At that boost level, I presume you'll intercool?

The issue you'll hit is that a post-PI car just doesn't have a low enough compression to support that boost level. While the pistons can take 400hp, you'll end up having to swap them out for a much deeper dish to handle that much boost without detonation, so keep that in mind. I'm not even sure if 18cc dish pistons will get you there. 23cc would get you in the 8.X:1 range. Manley makes a set. I'm assuming you also know that you'll need fuel system upgrades.

I found my PI heads on craigslist. They were $150 and low-ish (~30k) mileage. They were just take-offs. You can probably find an entire PI motor in a junkyard for $500-$1k.

I am aware of the fuel system upgrades.. most turbo kits come with the stuff to do those upgrades.Next ? what if i want to run NOS to get rid of turbo lag.. And would you recomend just getting a PI motor or just doing the swap.. With 400 hp would i have to do any major suspension mods. i plan to lower the car just a bit only and inch or 2. and i would like to get a set of 18 in. wheels for it.. What will 400 horse get me at the track
