Well, for one, the pipe doesn't go around...And two, the stock 87 plenum is so big that the turbo won't have room to fit on top of the motor...The plenum I used is one that I custom fabricated so that the turbo would still fit in the stock hotair location...The 87 lower intake isn't modified at all, except for two extra holes drilled into the lifter valley cover plate, it is still as stock as when I bought it new from GM...
Let me just say this...If you are thinking of doing what I have done with an 87 lower intake, STOP, and don't go any farther if you don't want to put a lot of time and money into doing this type of mod...It is not quick and it is not easy...It was an experiment by ME to see if it would work...It takes a lot of fabrication and if you don't have access to a machine shop, where you could do stuff for free or cost next to nothing, then try something else...This ain't cheap and it ain't easy...I'm a machinist, so I had access to a very well equipped machine shop, so if I needed something modified, I did it... I have since come to the conclusion that this setup has NO advantage over the stock 86/7 setup and still has at least two MAJOR disadvantages from the 86/7 setup, those two being the DP setup(The BIGGEST disadvantage) and the turbo is size limited on top of the motor(the turbo actually sits up slightly higher on my setup than on a stock 84/5 setup)...Combine that with the throttle body relocation that I had done, and IT JUST AIN'T WORTH THE HASSLE ...As time permits, I will be slowly swapping over to the 86/7 engine configuration completely, but that is still in the future...
BTW, the pics of the setup are in the links at the top of this thread...Those are the only pics out there, except for a few that got sent out to some people 1-2 years ago when I started this project...I no longer have those pics...
