any one have a list of engines that would work with the xb2? ether bolt up or some slight motor mount mods? i saw someone tried a v6 tc but lost intrest. just not sure if toyota has any bigger inline 4s than our 2az-fe. ill post info as i find it myself. if you have any info this would a great place to post it so we can all know!! also is there any heads that bolt to our 2az-fe that would help boost power? please dont bother posting " if you have money anything can happan" bull crap. i would like real info as i think the other members would too. thanks for any info!!
