Rebuilt 4g63 problems

[XevileagleX]

I just rebuilt my 4g63, it starts white smoke comes out of the exhaust, which may be caused from putting gear oil in the cylinders to create a seal between the piston rings and wall. However the issue I have is every time I shift I have to either shift really fast not letting the RPMs drop cause if I shift normally I have to go all the way back down to about 1000 RPMs then back up and that's in every gear. What would cause that? But if I shift fast enough its super fast. Second, it seems like it floods itself. What would cause that? I used a Nippon Racing rebuild master kit. I have heard that some new rebuilt motors may smoke, due to burning residue oils. Third, when I go over 7000 RPMs it cuts out, shuts off and won't start for a while again. What would cause this? I am new to the 4g63. I had a 97 talon ESi which has a 420A. I now own a 95 awd TSi. And its seems everything is backwards. So any help info and suggestions would be so greatly appreciated!!!!

Well first and foremost I have to ask why you are revving out to 7000rpm on a rebuilt engine. The proper method ( in my opinion and that of many others ) is The Motoman Break In Method.

Secondly, did you properly measure your clearances and set the proper gaps for your rings?

Third, What modifications have been done to the vehicle? It doesn't look like you have anything updated in your mods list.
