This is a good article on using a VG33E block with your VG30 heads. http://www.motoiq.com/MagazineArticles/ID/1298/categoryId/80/Project-Pathfinder-Part-10-How-to-Build-the-Nissan-VG30E.aspx Red at Accurate Machine shop here in Vegas http://www.lvmachineshop.com says he can easily get around 300hp out of a stock VG30. Pre 96/OBDII dont have all the crazy emission crap you get with an 98 Xterra or 96 Pathy (I have a craigslist addiction and own a WD21, WD22 and R50!) I just replaced the motor in my sons WD22 Xterra with a 53k mi JDM in March- I had to strip off the alternator, AC comp & brackets, oil filter adapter, and oil pan and plenum. I also replaced the rear main, timing belt, water pump and thermostat. Its basically a long block that you have to take all the crap off of to use for whatever vehicle you intend. Its a good little motor that was used on Pathys, Xterras, Quest's, and Mercury Voyagers. I plan on taking the old block and heads to Red and have him see what he can do with it.
