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

Why the goal of 500?

Just never had anything that fast
Had 400whp rb25
Just want to feel something a little more
But still not insane like 800-1000

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.

well also depends on the turbo on the RB, it looks like it probably didnt start spooling til pretty late

but i also see your point
