Rb25det Half Cuts

[fr0st]

It depends how far you take it, You could put in forgies, use a RB26 head, new turbo, manifold, ECU etc. and get the bill into the 10k area

If you were to build an RB30 with all the standard gear on your RB25 you can run it off your stock management. Alot of people do this to break the engine in. After that you can just keep adding to the beasty to get it where you want.

If you manage to find a good condition RB30 bottom end you might not have to rebuild it. Otherwise you'll have to go through Nissan/Holden to get new pistons, bearings and head studs. Get the rods shot peaned and the crank cleaned up. New timing belt aswell (forgot about that).

You'd be doing that for an RB25 rebuild anyway so I doubt it would cost any more (probably less). I'd get reading, you'll learn a lot from that thread

About the torque, 300kw RB30 torque > blown LS1 torque. There evil

Or you could just buy a built RB30DETT.. fully built bottom end, 2x GT2540s, complete engine with all the fruit currently making 494rwhp @ 21psi (graphs available), I think he's asking 10k. PM me if anyone is interested

Oh and it was tuned by Ant @ Xspeed but sale doesn't include the ECU.
