87 IROC with 3 inch cross over..
so this is the plan, 355 with S475 turbo, jgs WG and BOV and CSU 750...now the problem is...
im using the ebay headers, modding the back tube so it clears the steering shaft and cutting the flanges up front and doing vbands on them...car still has ps and alt and water pump....also has a griffin rad
now i was under the hood yesterday for a few mins and noticed that there is not much room to run a 3 inch cross over pipe to the turbo that is going to be mounted on the pass side where the batt used to be...sway bar and wonder bar take up a lot of room right where the pipe would like to go....
and the sterring box is might close to the ps pump but i might be going with a small circle track ps setup which mounts on the drivers head very small...
basically i wanted to see if anyone has any pics of how they routed a crossover pipe to the turbo with the sway bar and wonder bar in the way....
any help would be appreciated so i dont start cutting up the car and makin room....thanx guys...

I used a 2-1/2" crossover and have plenty of clearance from pulley, ps, fan, sway bar, and wonderbar. Not the best pic, but it's the only one I have at the moment:

Re: 87 IROC with 3 inch cross over..
Thanks, I can't remember if I did or not since it was a few years ago. I do remember asking for carb tuning advice there b/c I could never get it to run well at part throttle.
Also, for the OP, to visually see if the crossover will fit, get a short peice of 3" tubing and move it along the front of the engine to make sure it clears everthing. All the accesories looked really close when I was building mine, but after I did that little test, it was easy to see that I had enough room.
