RB30-ZED Posted September 15, 2004 Share Posted September 15, 2004 Thought this might be of interest. The two pics are G-Tec screen shots, the first one is a horse power comparison and the second is a 1/4 mile run. The RB30DE is a naturaly asperated engine with 10.5:1 comp RB30 block and RB25NA head with standard cams Kalmaker engine managment. The RB25DET is a standard R33 Skyline turbo. Note: G-Tec shows a lower HP than dynos as it taked all drive losses and aero losses in to account. The RB25DET is good for 180kw(241HP) at the flywheel and the RB30DE a bit more.

Guest Mateo Posted September 16, 2004 Share Posted September 16, 2004 How much did your RB30DE set up cost you total? Very nice BTW by looking at the curves. Im looking at doing a RB swap but have always liked a strong NA engine than a turbo because Im crazy or sane from deciding from which your into. Your swap just urges more towards that route.

RB30-ZED Posted September 16, 2004 Author Share Posted September 16, 2004 It didnt cost me much at all. I picked up the new block and crank for next to nothing (long story). The complete top end was off a RB25DE which i got for $400AU or about $300US. The guy i bought the head off through the RB25 pistons in for free. The engine managment was $1000AU($700US) Lots of people ask me when im going to turbo it, the answer is never. ITs got so much bottom end grunt it will pull 4th from a 1000rpm. I had a guy with a 230kw(308HP) amazed as the zed out ran him out of each corner and on to the straight each lap. The flexability of the engine is its strong point.

Tony D Posted September 18, 2004 Share Posted September 18, 2004 Two things I can say: 1)OY! Looks like it's time to upgrade my G-Tech to the new generation! 2)Egads, forget the graphs, that R33 subframe swap is beaut! Thanks for that link, M8!
