My vg30 had about 180k on it and alot of pulling a trialer around for motocross racing, that vg30 was waisted and needed a serious rebuild. But I wanted to do the vg33 upgrade. I picked up a 0 mile vg33 from Felton's all Nissan auto wrecking for $1700 in 2005. No one had done that swap yet but I figured it out. With the lack of time I had to work on it and putting my cash in to a S13/Skyline build, it took about four years. It has about 10k on it now and runs very well. It has stainless headers, 2 1/2 exhaust, adjustable cam gears, puller fans, MSD 6a, Stillen intake. Now I'm gathering all the parts to do the factory supercharger. I have almost everything, and only three more parts to buy. The lower crank shaft pully, the ac compressor clutch, and the supercharger it self. I'll be useing a Vi-pec computer and get it tuned.
