Man I've been selling stuff in my garage to afford stuff(old parts from my M3,integra, various other Honda's) and it still taking time. It'll all be worth it in the end though.
I originally was going to drop in a Rb25det/RbZ32TT tranny. I had the tranny already but no engine. Then I started researching and found that it would be easier to get to my whp goal(550-650) with a LS1. Plus parts are not as easy to come by or as cheap when compared to a LS engine. I was trying to sell the 4.8 I'm using now(got from my dad) to get rb parts but after my the research I that both engines weigh roughly the same(a slightly heavier on the V8), So I convinced myself but now I need a t56(roughly the same amount for a RB engine). Rather then try and save up for a tranny I spent on suspension, drivetrain, brakes and fuel system(fuel cell, pump, braided lines, fittings). So its been a year now since the purchase of my 74' 260z($450)! Recycling plastic, cans, bottles has helped out too.
Goodluck !
