The basic setup is a sleeved b20vtec, pistons, rods, built head, Tial wg and bov, Fabwork mani, 3"dp, 3" straight out exhaust, 60mm master power turbo tuned to 11 psi on 93 octane on Neptune by a very reputable tuner.
The car has always smoked a little, but nothing worrying, just the normal little puff here and there that a turbo car will do. I have been driving it in the current state for a couple years now with no problems, but lately it has started to smoke more. After boosted pulls it always puffs a bunch of smoke that smells rich (smells more oily than gas). Smells a little richer at idle too (has no cat and barely a muffler). It doesnt seem to be consuming any noticeable amount of oil when i check it though.
Today i pulled the plugs and did a compression test. It was perfect... 188, 182, 185, 185 on my Snapon gauge, cold motor. The plugs were very black, not oily, more sooty...
Im going to put some new plugs in once i find my gapper . I guess im looking for theories on why it has started smoking more? Think it was just the plugs fouling up over time? They are old, several thousand miles, and they are NGK non resistor cold plugs (what my tuner recommends). What im more worried about is thta maybe my turbo is the source of the smoke. There is some shaft play, but there always has been and it didnt used to smoke this much...
