I put a stock GZE in my ke70 for about $3500 doing all the work myself. Add another $500 for a 55 for custom mounts and tailshaft. Thats 4k for something not even built. Then theres my cams $600, SC14, $350, FMIC $100, 2.5" piping $100, 7mgte injectors $100, thats another $1300. Over $5k without opening the engine.
Just an idea on prices.
