Actually the R34 GT-t does not have the traditional RB engine. It has the NEO 6 engine, which has proven to be more powerful than the RB25 but at the expense of reliability, i have seen NEO 6 engines easily pulling out 350kw with no dramas. The 1JZ GTE engine is by far the more reliable engine but im most familiar with it sitting inside a supra, not a chaser...
