Pat, I think you'll be more then satisfied with new motor/blower/nitrous combo... it is what stopped me from giving up on my setup for now. I only sprayed a 50 shot on the dyno and that netted me 70 rwhp gain.. I've since sprayed 75 shot at the track only adding almost 10mph on the big end and shaving 7 tenths in the 8th! I can't imagine what a much stronger platform to begin with like yours would do, and you won't lose any fun factor of the pd blower on the street... if u need any help let me know. This is my third nitrous system I've done and I'm getting very knowledgeable on setting it up....

 

My T4 is an 80/87. It is a great all around setup in my eyes. It is making decent power and is fun to drive on the street too!
