Wtf is with my car?!

[Phillyb]

Ok this is the second rb20 my car has had put in. 89' gtst type m. Ever since the new engine was put in its been blowing some smoke under boost. i assumed it was the turbo so i replaced it. there was oil in the hardpipes and intercooler (drained and cleaned all that). Now the other day i started my car and it has ZERO POWER, hardly makes it uphill in second gear (it would normally be spinning out under full throttle.) I know it isnt an ignition problem because i just installed yellow jackets and new spark plugs gapped to 0.8. Really not sure what to do here and i dont wanna drive it the way it is. ill post a vid of me revving it up. It revs SUPER slow compared to normal and feels like it has AT LEAST half power. thanks in advance

Fuel pump/injectors?

That would be my second guess. I'll take it to the shop to make sure

Could be coilpacks if misses throughout powerband, especially when engine runs on 5 cylinders that makes engine feel like it has lost power. I hear some have been having problem with those coilpacks failing on higher hp R34GTR's (might be coilpack setting related).

Other is injector (as mentioned above), intake manifold leak.

Make sure your Cas is plugged in Fully, simple stuff just go over what the guys mentioned above. Buddy of mine every time the engine flexed the Cas plug would not have full connection.

My Guess is Cam angle sensor tho.

Yea i checked all the plugs on everything, I didnt take the CAS off to look at it though, maybe it broke? but it honestly feels like its running on 2 cylinders. Sounds like a Harley. Perhaps i blew the welds on the intake
