no doubt the increased displacement makes a difference. But fact is, I'm not a fan of V-engines, I like 'em straight...unless it's a biturbo V12
The tuning potential is well-proven for the RB26. Virtually any desired power output can be achieved with, if you look at it honestly, mere pennies compared with most other (non-Japanese) cars. How much does it cost to build a 1000bhp RB26? A lot, but it can be done with a click of the mouse and a very large paypal account. How much does it cost to build a 1000bhp Lamborghini? Hundreds of thousands of dollars of custom work, and no guarantee the thing won't blow up on its first dyno run. You could probably order up a 1000bhp BMW M6, but it'd be at least double or triple the cost of a 1000bhp RB26.
But I'd take the transmission. The word on the street is that its the fastest semi-auto available.
So how about adopting the R35 transaxle to my R32

Then I'll be happy.
