Quotehe said it would run forged pistons h rods tommi cams thanks again rod
Lol, how much money do you have to spend that is sounding VERY expensive.
IMHO anyone talking about running any kind of RB20/25/30 motor N/A is nuts. The beauty of the RB motors has always been the copious amount of power you can get out of them reliably with boost.
How much $$$ do you have to spend on this conversion?
I think the RB swap and the V8 can cost about the same, it all depends on how you source your parts, how knowledgeable you are, and how much work you can do yourself. A conversion that costs under $10K for someone can cost $20K+ for someone else.
But as a general rule of thumb that has been told to me, and I have found true almost every time, whatever you think a project is going to cost double it and you will have a reasonable estimate. :) No kidding!
But may I ask what you want from this conversion?, do you just want a reliable and fun driver, if this is the case I would just go V6, plenty of torque from 3.8l, the conversion has been done plenty of times and parts are so easy to get. A V6 can easily make more power than a tired old badly tuned 253/308.
