what might the hp rating be on an 87 turbo that has 3 in exhaust, intake, maxima alternator (not sure if this helps with hp?) ? also the guy said he has a manual turbo controller, what does that mean ?? that he can up the boost?
Yeah depending on if it's a full 3 inch exhuast, meaing from the turbo back vs just a cat back, with intake he probably gained 20-30hp over stock. With the boost controller it depends on what boost he is running. Chances are if he doesn't have an intercooler it's probably set to around 10psi. Assuming that he probably has something like 250-275 depending on how well tunned the car is and stuff like that.
