Is their any of these running in the usa yet

sure a lot of thought about it but nobody built one yet ?

 

2.6l ???

 

i think the biggest is 2.4l

 

hasn't slowboy racing done a 2.5L?

 

wouldnt that make no since b/c of such a long stroke couldnt you not rev it at all?

 

Yup. SBR sells a 2.5L

Haven't heard much about it though.

 

wouldnt 7000 rpm be enough when you would get power really really early ?

so i guess no ones done it yet - im surprised because usa boys are normally first in with everything

 

Brian Crower sells a 2.6L kit. I have not heard anything good about his stroker kits though.

Going from a 2.0 to a 2.3 or 2.4 the most people see is around 500-800rpms spool faster.

It all depends on what you want i guess. If you want some big turbo that can keep power up top i wuold rather give the 500rpm spool and gain the 2000-2500rpms redline.

If you want a smaller turbo then ya a stroker is the way to go.

well , for autox or simular is great. But road race or drag where you do benefit from higher rpm , i take the higher rpm engine .
i dont want to comment the second part...

 

SBR is working on a 2.6L variant of the 4G64 (which is what their 2.5L is based of of as well)

 

What would be the hypothetical redline of a 2.6L 4G63? I think it is pretty silly idea, but still curious.

probably the same as a 2.4-2.5 motor. max 8k, safe 7500 maybe?

 

SBR says 8k for their 2.4 and 2.5. I'm not sure how they get to 2.6, but I'd bet the redline is similar.
