Just recently purchased a chaser (1JZ-GTE), and i must say its a better engine than the RB25. Stock vs stock the 1J is deff quicker. Well it feels like it. I have owned a skyline 33 (rb25) for 3 years, and now a chaser. Straight away i could feel the difference.
I would put a rb25 in that 32. Easier, cheaper and it will be less hassles.
