Ok then--nice. I am glad you decided to try and increase flow this way.
I may be really stupid but i still think those liners help kept the exhaust port as hot as they are. The water jackets cant touch them because of that dang secondary air pump space. IDK what do you think?
Are you doing to try and improve the lim also?

Nope - nothing planed for that . Going to try keep all other changes to a minimum so we can better judge the effectiveness of the modification I'm doing.

the rotors have to be milled to accept the deeper seals SLidin8. There are pics out there somewhere after this had been done.
Bret, you are probably right, without the liner the exhaust would get that area too hot.
If I ever convert to a map type system I would run the secondary air pump all the time
Hmmmm going for more port matching between header and exhaust port?

one example, there are a number of builders who provide this service as well

Picked up a RX8 5 speed transmission . Now I have 3 transmissions LOL .
My old one , a near new 6 speed plus a 5 speed with 90000kms on it .
Thinking I'll fit the 5 speed because the ratios are much taller 4th = 5th and 5th is taller than 6th so I think it will be more suitable with the extra power.
+ i'm told it has the same internals as the FD trans which is ,supposedly, stronger than the 6 speed.

Why coat the outside of the sleeve or even the port? There shouldn't be that much exhaust passing between the two, and I doubt the ceramic coating will have that much effect on metal to metal contact. Why not just coat the inside? Get all three sleeves and hopefully reduce the temps of the iron/coolant system. Don't know if it would hold up well, or provide much of a benefit, but after I hit the rotors I'm gonna use what's left for the ports.

That stuff could fall off and damage the turbo .
