I did a search on this forum and I read some people talking about making a bridge port on top of the actuator ports that open up at 3800 rpm. Seems like a good idea as your idle and low end torque would still be decent as that big port would be closed before 3800 rpm. Anyone try this or have experience with this setup?

 

That port is simply way too big. Your power band will be to high to be usable.

 

What's your estimate on where the peak HP lies? Higher then the 10500 rpms? Heres the link on it, I don't quite understand when the guy says don't port the bridge all the way to the floor?

It sounds like a good idea though since you can still keep it streetable if your ports don't open up until 3,800 rpms.

Try it and tell us!

Oh all right... I'll try it this summer...

 

Heh I'll think I'll try it, maybe not a full bridge port, but a half bridge combined with your mild/extended street ports. I'm planning to try to transplant the 13b N/A into a Corolla GTS (Ae86)
