I imagine torque ratio would be horrid without FI. At least with FI and a boost controller you would at least get the amount of power that's warranted for the amount of fuel used.
So let's say after boring it out, you decide to FI to level things out some. You are looking at 12k minimum to the 8kAt 20k+ you can get a factory GTR motor that will give you less problems overall. Then other supporting mods... that will be a 30k engine to make it run well.

Not worth it imho but that's just me though. I guess thinking like someone who just likes experimenting with shyt? It might be a fun thing to do for some?
