I'm putting a list together of what I'm going to need for my new car. I cannot decide whether to use my JP Modded Mugen X12 or get a new engine.

How does the JP Mod X12 compare to the newer engines out today? I've been looking at the Max power XXL or a Murnan Modified RBM3. I know those two are very high end and offer way more power than I might need, but I figure why not Anyhow, I was wondering if the X12 was worth using in a new car or if newer motors outclass it and I should leave my current car as is while starting with new.

if your on a budget look at this,best bang for the buck...

if money is no object look at the maxpower xxl3,

i have both above plus a couple of jp fx black engines, nova plus 12-3ct's and a few JL picco's so i speak from experience

So how does the Maxpower XXL3 compare to a Murnan Modified RBM3? It's based off an RB t9. Also looking at the Murnan RBT10RC which is quite a bit more money than the Maxpower.
