grand turismo question

i got a civic type R and i wanted to know if its possible to do the NA tune up then add the stage 3 turbo on to the car with horsepower gains
cause i know that once you have a turbo and then do the tune up, your horsepower will go down

ok you either do n/a or turbo
they both dont work together and you get all those basically so you can do different types of races which have the requirement of a turbo or n/a...... GT is very realistic after all you are going to put a stage 3 n/a in a car that has the compression at 11:1 then put a stage 3 turbo on the car, it doesnt matter how much you have that car build up with that much pressure it will blow up

exactly. The reason you noticed the HP go down because Gran Turismo is taking the turbo off the car and doing the N/A build for the motor.

On an unrelated note, I wish they left the BOV sound in the game for GT3 and 4 like they had it in GT2. I know you can hear it in the "in car" camera angle, but once you go to an out of car angle you can't hear it anymore...

I had to quit playing GT3...I ran out of controllers to break.

Have you guys ever played Forza Motorsport (I'm an Xbox dude myself)? Its an excellent racing game and beat GT4 by a 1/10 of a point in ratings. Its unbelievably realistic and fun. Check out this vid, it shows you how much work they put into the game!

Bad quality though:(

I've never played it, but I've heard nothing but good about it.
