> In my opinion, 500whp for a daily driver sounds really stupid. Do you have a diff as well as really good tires that will allow you to hook up? 500whp in a 240 is way overkill in my opinion. Not sure how responsive it will be with that turbo but since it’s a higher displacement motor, it might be be… I don’t know much about RB’s.

Fabwall, bud come one!!! Why 500whp as a daily driver dumb? If you have money to build a RB I think he will be able to afford some drag radials to lay the traction down.

I donot know why most of you guys think you will have no traction with any horse power over 400whp!!!.

It all comes down to your setup.

Born2beaskyline if you want 500whp do it!!! just do your research, I think the oil pump is the weak point. Not sure so do not quote me. We have a RB26 in the crew and the oil pump has to be upgraded when pushing does numbers.

Dan from U2NDYNO is the man.
