hello all, I am brand new to this forum but not new to the auto world. A little background, I live on a farm have done all mechanical work to all tractors implements trucks so on so forth. Graduated auto school three years ago and went right into ford. Am certified through ford, Volkswagen, and ase so I am somewhat inclined. Now to the question. I have a little over 22k in my 96 4.6 gt and am currently hiding wire/welding in panels. The engine is being dropped in soon. I do a lot of side jobs so I have 2 02 Subaru wrx turbos that id like to fabricate onto the mustang. I see kits everywhere with 76mm turbo or two 60mm turbos but I wanted to know if the two (I believe 42mm) turbos would add much to the car? I initially built it to 5.1 heads cams etc. the whole nine yards and actually took the motor out and sold it to a close friend and in return he gave me his 02 gt pi block that runs perfect. I do not want to stick really any more money in the car so that is why im using the Subaru turbos. If anyone has any insight on the twin 42mm turbos like how much boost I can make how many lbs of air they could produce before I waste my time mounting everything and tuning the dam thing. Any help is greatly appreciated just don't tell me to buy a kit or to buy a bigger turbo I have a lot of other stuff to spend that money on and don't want to keep adding to the cost of the car at this point in time.
