I am starting my RB25DET swap soon. I can't wait! Hoping to have it running by the woodward dream cruise.

Well I finished the rb swap long ago and decided it was about time for an update. A full tutorial of my problems and obstacles can be found at Z31Performance.com
I did finally find some new shoes.
They are mustang bullitt replicas. Fronts are 18x9 offset 24, Rears are 18x10 offset 22. I installed 245/40R18 cooper 2XS's up front, and 275/35R18 yokohama AVS sports in the rear. The wheels are a direct fit for non turbo Z31's. However with the tall profile of the front tires and the turbo front strut tubes there was a clearance issue. I installed a 8mm spacer so the tire clears the strut tube by about 2 mm.
Before I set the vehicle on the ground I installed a new set of Race springs with a 1" drop in the front and .5" in the rear. During the suspension upgrades I also installed some poly stuff to stiffen up the 20 year old worn out rubber pieces.
After a short drive to a local exhaust shop I noticed a huge power delivery difference. I had them make me a new 3" downpipe and full 3" exhaust with a magnaflow stainless steel muffler out back.
I also had the shop bend me some new intercooler piping from 2.5" stainless steel and mounted a new treadstone FMIC discreetly tucked behind the bumper. Show Less
