Thanks for all your help guys. On the High Performance Imports video Vol 3. (currently being borrowed by me off a friend ), they show a S13 Silvia with a VG30DETT in it. Pretty PHAT I reckon!
And I'm not going to spend the money on my current ca because it is non-turbo. Spending 2k on my current engine, would that bring it up to scratch with a rb20det (serious question)? And I definantly won't be putting a rb25det into it because of the cost.
Also, boostmeister, what has to be fabricated/welded/altered to put the rb20 in the S13? I've heard that the heater hoses have to be altered and besides everything in the halfcut, you'll need a rb tailshaft and a bigger fuel pump in the tank. Is that it?
