L92 vs Turbo L33 Ok so still thinking of ideas for my FD
at first it was between turbo l33 and ls2
l33 won for power goals for the price, plus if i didnt want to turbo it right away
i could still have a little fun with a cam etc
but now looking at L92's and how its pretty much an ls3 with a few differences
I was wondering if it could match that similar budget turbo build of the l33
If im aiming for around 500whp
assuming i can get a full L33 for $1000
and an L92 Long Block for $2000 (Id need different intake, oil pan and stuff anyway)
Also would want to look at the weight difference
I couldnt find anything on how much a full L92 Weighs

Even a 5.3 at 400 WHP is going to feel faster because of the flatter torque curve.
Peak numbers don't dictate whether or not a car is going to be or feel faster than another. For example, this is a 405 WHP dyno chart I pulled from a Google search looking at RB25 dynos:
Here is a 414 WHP dyno chart for a LS1:
While the peak numbers are only within 9 HP of each other, look at the curves and the torque numbers under that curve. At 3,000 RPMs, the RB25 is making about 140 ft/lbs of torque, whereas the LS1 is making about 330 ft/lbs. That is a huge difference, especially when you are putting that motor in something light like a RX-7.
