Nissan L20-28 Engine (Hitachi Flat Top Carburator Intake and Manifold)

Due to some problems with my 3D Max, I've lost my last backup. I've been working on S30 Z chassis and interrior recently, and I want to convert it to GTA IV. So now I'm going to finish this L engine as quickly as possible, because I want to install it in my Z. At the moment, I've done new intake and manifold.
