Hi Bybath. I looked into this a while back after a dyno run showed the car had 322bhp and not circa 350.
After a lot of red herrings from the factory I found out on my own that the K24 3.5Rs run a lower boost, around 8psi, not the 11psi of the K20s. Tom eventually said that they found the inlet temps would go out of range if the boost was increased. I don't really see that given the very large charge cooler radiator in the side pod?
I looked at having a larger crank pulley in order to increase the boost, then a remap.
The ecu in our cars are not mapable. You would need to invest in the Hondata route. I looked at having the ECUTEK ecu installed as a slightly cheaper way of being able to remap, plus it gave a lot more features than the Hondata.
However, our ecu is everso slightly different to the 3.5, it would need an intermidiate loom made in order to go the ECUTEK route. This alone would cost around £1,000. So I abandoned the project.
It will be interesting if you find a way!
