Just have a few ?'s to ask about turboing the stang. What size maf to run between 10-15psi? What size injectors? Do we need a bigger fuel pump? I know we need an fmu and fpr but do we need a 10:1 or 12:1? Will a king cobra clutch handle it? Also will a garret t25 work or do we need a garret gt40? If we need a gt40 what cars did they come on stock? And I guess thats it.

1) I don't know about the maf... ask the tech or bs section on www.turbomustangs.com or call Dalton at Pro Turbo Kits and see what his ideas are.

2) 42 lbs

3) Yes, the 03 cobra pump works, but its not the only option.

4) king cobra clutch will not handle it

5) the gt25 is a smaller turbo than the gt40... honestly, you are better off choosing a hp/tq goal rather than a boost/psi goal.

6) I don't think the GT40 turbo is used on any stock cars... maybe a truck that I don't know of... maybe a semi or something, but not that I know of.

MAF is depended on the fuel system and how much power you can make.
10-15psi is too much from a turbo on a stock car unless the turbo is really tiny.
42 injectors or bigger depending how much power you want
Yes you will need a bigger fuel pump
10:1 or 12:1 compression is way to high for a street car with forced induction. You will want want around 8.5:1 or 9:1 on pump gas
a t25 is a small turbo, you will probably over boost it.
Not sure what cars come with a GT40 but I would try to find something in the 60 trim area.

I didnt mean 10:1 or 12:1 compression, I meant the fmu. And the bottom end will be built before the turbo. Compression will be about 9:1, and we will only be runnin about 10 psi.

With the right fuel system you would dump the FMU which is a good idea anyway. It is a bandaid for too small injector size.

Hava you thought about going DFI?
