I put plenty of miles on my RB20 when it was running, and I really had no problems.
I went from a 120-130whp sohc ka to my 217whp/206wtq rb20. It felt great I didn't really notice any big issues under steering. When it did understeer, it was worse but if your understeering in a KA, your doing it wrong.
One of my friends that competed regionally had a s13 coupe, rb20 13psi, front mount, 12 pt roll cage, welded diff. And his normal front tires were 215/50/16 BFG taction ta all seasons. He had no problems, and I would have loved to have his car as is.
Tire compound has far far more to do with traction/understeer then engine weight. Even though the engine adds weight to the front of the car, it still gets distributed at all 4 wheels.
At work we have corner weight scales, and if I remember, or get the time I will weigh my car with a KA and RB in it. I would do it in the next couple days but its just a shell and I'm working on the roll cage right now...
