The last time I put my RB20det on the dyno it was doing 216 HP @ 118 kph. Since the have rebuilt top end ( found 3 sheared off studs on exhaust manifold, screws missing from valves on carburetta, and leaks everywere...), installed large intercooler, put on a rollerbearing turbo from R32 and replaced dodgy old exhuast.
Still yet to re dyno but am expecting for around 245 HP. will let you know how it goes.
