So the 24# kinugawa w.g. actuator didn't make much difference, do I actually need the eBay header? Head has stock valve sizes, ipd turbo cam.
Sorry, but I didn't follow, what engine?
If you are hoping to run 24psi on a small turbine wheel, you might be asking too much.
That's very high boost with most redblock/whiteblock with a TD04 turbo!
