I agree with MJtru I think I'll re build the bottom do the basics good head gasket arp studs and bigger oil pump and bigger sump, new timing belt water pump. Just leave it standard too begin with and upgrade turbo and comp :-)

No point in spending big bucks to rebuild rb25 back to standard - don't waste your money... Either throw in a rb30 bottom end or just get a second hand motor and throw it in your car.

I would like to follow this and see what he does. Drifting you will need to rebuild that old RB30 in no time. If it's not already shot. Well one good leason I've learned if any is. The most expensive idea I ever got was a free one much less a free engine. The 30 could work, all in saying is you will never know the health of the components in that rb30 block. Please keep us posted mate. I would like to know what you did. Both options can work, just work with new parts in them that's all I'm saying. Me personally I would go back with rb25.

If the ringlands are gone then chances as the bore a scratched so it depends if the damage can be bore out or not, on the other hand if the cheap or free RB30 block just needs a hone and rings and bearing then RB30>RBless capacity any day of the week and twice on Sunday

And the RB30 is an easier fit in to a R33 GTS-t then any GTR and plenty of GTR owners ( me included ) haven't gone to the trouble of fitting them for no reason

I have a "drifter" and everytime I look at it and how it was treated and look at how much his previous owners poured into him and I think WHY!!! I'm hoping to bring "Bashful" back to his former glory!!! Love my car even tho secretly I think he wants to kill me

Toys are not just for boys!!!
