Dyno'd my Nistune turbo VE today
WOW 
I sell mine in 2002 and finally take a peak back in here and see a bunch of boosted 3rd gens!
Love it! Congrats James!
currently I'm driving a '92 Q45 (soon to be boosted V8)...rear mount turbo build, should be a lot of fun. I just can't seem to get out of the 90's with cars.
Not a month goes by I don't miss my '89. Hard if not impossible to find clean ones anymore.
sorry for the threadjack!

Any boosted engine will get some oil in the manifold which will equal some loss in power and not over not good.
After doing a lot of reading on the subject, Im going with a Sikomichi duel catch can set up. 1 for front valve cover and 1 for rear Valve cover. Front Vcover will vent to catch can to catch any oil then go back into charge pipe line before SC inlet so its all metered air. The rear valve cover will come out of PCV into catch can then back into manifold. I think this is the best set up for a clean engine and proper tuning so you don't have any unmetered air going into the engine.
Going back to my original post, gapping my BRK6E plugs down to a .32 gapped got rid of some of the exhaust sputtering but not all. Im sure gap as well as proper AFR played a roll in the sputtering. Unfortunately I had blown pistons rings in my 3.0 and Im going with a 3.5 swap swap on 3.0 timing full 3.5 engine build. Gonna be running 560cc injectors with a return style fuel setup. I also switched from EMU to Nistune.
I'll be getting my car back sometime Late March early April and getting a tune will a Legit tuner.. probably Evans Tuning in PA. He's one of the best tuners in the East Coast, so hopefully this time Im in good hands.

Well, part of my issue is that my MAF is on the charged side. Pull-through setups seem to be solved a little bit easier as far as the PCV stuff. I absolutely just do not want to route any potential oil back through my setup and potentially through my MAF.
Of course the intercooler would likely act as a large catch-can, so oil going to my MAF is unlikely, but then again I don't want a bunch of oil in my intercooler either.
I have dual catch cans but never installed the second one on my VC vent. My second catch can will now go in between my VC vent and my vacuum pump. Can't have any oil going through the vacuum pump and causing premature failure on it.
My AFR's always were very good and consistent. Even at that though, I've still been somewhat leery of my tune due to my very random and sporadic spark blow-out type symptoms. And again, since I've never experienced
My tuner blamed some of the symptoms on coil packs. He is very familiar with Z32's and said they have the same issues. I know all my coil packs themselves are good, but I have Aaron's phenolic spacers on my car, which causes the rear coil packs to sit a good 1/2" higher on the spark plugs. I suspect this may make the coil packs susceptible to poor spark conditions. I tried to lengthen those little springs on the coil packs to make up for the increased distance but who knows how much it helped. I won't be installing Aaron's spacers on my new engine

Well keep in mind this is just my personal speculation/conspiracy theory. May be a non-issue in reality, but the rear coil packs sure don't fit very snug over the plugs with the spacers in place. I just want to rule out one more variable
