$1599 is not bad for what your getting.... Concider a supercharger that can make the same power is $2000-$3000 just for the blower itself. For the same price you can get the same turbo I run in my cobra thats good for 1200 hp at the crank. Thats the Precision 7675 billet wheel but, it won't spool quite as fast as the 7175. Now your power goal is 700 crank or wheel hp?

I could prob cut you a great deal on a used precision 6152e turbo I have sitting on the bench.. It's the 5 bolt 63 AR discharge.. It has some chips on the hot side wheel, so I do recommend you ship it out to precision for a rebuild which is less then $200.. It supports up to 650 hp as is, and is smaller then the one fangs spec'd, yet bigger then the STS kit turbo. It should get you spooling with minimal lag due to it's smaller size, and it will build boost quicker... I've also got air to air and air to water intercooler setups to throw in on a deal. I've got these parts lingering from when I was going to turbo my 5.4 3v, but then I found the whipple..

Keep in mind you will need a remote oil pump to get oil to the turbo and High flow cats are a must. The reason why the exhaust wheel on mine is chipped is due to cat converter shooting pieces of material through it when it blew apart.. It still works with the chips on the wheel, but for the cheap money it takes to fix it I wouldn't leave it as is..

I can get you pics of the turbo and parts if you'd like.. H

.63 AR will choke the engine up top..... My little 4.6 spools its 7675 almost instantly with a .96 AR....... That turbo would be good for a twin setup... But the OP needs a T4 flange setup to allow the engine to breath through the whole rpm range. It's not good to maxout a turbo or run it above it's efficiency range. 700 crank hp is around 500 rwhp and the 7175 will be good for over 700rwhp. OP, the turbo I spec'd has 2 exhaust A/R housings and they are only about $100 each so you could order it with the larger .96 AR and if you want a faster spool order the .81 AR housing

How will the smaller affect the top end of the motor and I am thinking of running long tube headers without cats is this a good idea
