I had a BGC stretch and it stuck out of the bottom way to far and I had less than 3" ground clearance. You also got to ask if it will allow you to run your front sway bar or not, And my BGC also would hit the oil filter because it was to wide. I had to get rid of it because of these problems but it did make my car run alot better. Especially on pump gas. I was able to run about 4 more pounds of boost on pump gas with it d/t it cooling down the charged air so much better.
I also had a PTE front mount on my GN and had to deal with all its associated probs. So when I went looking for a IC for my TTA I was determined not to go FMIC. So I went with the BGC stretch and that was a failed experiment ( but would highly recommend a strecth for a GN with its extra ground clearance). So now Iam going to the ATR TTA liquid intercooler set up with the front mount heat exchanger. I believe Iam going to add a custom water/ice tank to this set up for at the track. ..wish me luck! because Iam tired of buying IC's.
