92 da8 obdo2 b16a block b18c 96 pr3-4 head

motor's freshly installed, timings good and sounds the part!
problem is now im blowing a sh*t load of black smoke and overheating.
i found black smoke is generally excess fuel not getting burnt/too much fuel in cylinder. (correct me if i am wrong)
the head has had work, new valves seats etc, ported not polished =( acid dipped.
block standerd as.

things i have tryed: nothing. droped the tank(had old gas) and put more in. havnt turned it over yet.

what is causing it? and how can i fix it.

been searching all over for info and havnt found anything usefull

do you have an after-market fuel pressure regulator, or is it stock? sounds like too much fuel delivery to me..

as for the over heating..since its a fresh motor im assuming you performed new water pump timing belt service..any signs of blown headgasket (milky looking oil? coolant smells sweet coming out the exhuast?)

what ecu are you using?

standy xsi

i brought the motor as is. got told had a new headgasket an havnt had it running long enough to bring up the milky looking oil. its still gold. an nah deffintly not a sweet smell, iv'e expirienced that before =/
the block's still stock.
but you would think he would have of used a new if not near new water pump after goin threw the trouble of sending the head to the shop and spending the $$$
yup stock fpr
could i have hooked the vacume lines up wrong? would that efect it?
dirty or clogged injecters would retard the amount of fuel aswell ae?

im sure its not oil. no sign of blue in there and its giving a gas smell from the engine bay.
as for ecu im not sure.
i havent changed it and i use to have a b16a2, so it would be the one that came with the conversion package many moons ago

c'mon ht any advice as how id go about diognosing this situation

DirtyDA9

Buy an aftermarket fuel pressure regulater, a wideband O2, and a tuning device. As for the overheating, maybe are bubbles in the coolant lines due to just putting the motor in.

standy xsi

would a 97 spec itr fuel regulator do the trick? can get fuel rail fpr an fuel line to filter for $50.

wide band 02 sensor? aftermarket aswell?
yea im not sure wat it is, been busy so havnt worked on the car for a few days.
gunna get the black smoke gone then worry about that..
just a thought, i was thinking since im burning so much fuel would that cause it to overheat?

DirtyDA9

I would recommend an aftermarket FPR with a guage, unless you buy a fuel pressure tester, but that would just be a pain. And a wideband is aftermarket, stockers are narrowbands. Widebands are a necessity when tuning, it accurately reads your air/fuel ratio.

And running lean would cause overheating, too much fuel would not.

standy xsi

hey so im going to buy a fpr jus doing research about it.

here it is
