Three questions thanks

1. how much power does stock N12 E15ET have.
2. I've got a 85 EXA,i wounder if it's EFI or not, and how many valves per cylinder are there.
3. Previously i had a yellow sticker for black smoking, and i take advices to rebuild and high flowed my stock turbo, how many psi would it have. they said it's gonna be around 20% more power, so how much psi would a stock turbo have. I did ask the mechanics if i can put a larger turbo on, and they said it can't be done, they show me a large turbo and ther are five nails kind of stuff on it while my stock turbo only have 4, so what's this T25 is all about, how can i put it into my car and how much does a T25 cost.
thanks

1. 77kw
2. yes, multi point efi with 2 valves per cyl total 8v
3. black smoke is fuel smoke, indicating there is too much fuel going into your motor and its not all getting burned. Fix the problem, its not stuffed turbo or motor, oil burning is blue.
stock boost is around 6.5psi
all garrett turbo chargers have the 4 stud design, so the turbo you were shown was not garrett.
the t25 will bolt to the stock manafold, expect to pay around the 350 mark for a second hand good nick turbo.
If your mechanic says its not possible, find another mechanic.
basically the t25 is more efficient than the stock t2, can handle more boost and most importantly can flow more exhaust gas.

depending on what was done to the engine and turbo 1200 is pretty good i reckon.

as for not being able to upgrade the turbo, shove the t2 in his face and ask him how thats supposed to crack any reasonable power and show him the e15et top 10 link.
