well the plot thickens and my lips are still savoring the QR as my daily
but now seen the PR head, by chance found a bottom end that is based on
the QR engine yet is stronger cast iron with the usual 89mm bores.
"The engine shares much of its architecture with the QR petrol engine. "
This is likely where the fully counterweight post 2007 QR crankshaft and supercharged QR rods
were sourced from the same engine to save in costs.
BEEF!!!
This is theoretically a better option than sleeving the qr25 for 2500usd as offered in the US
No need for sleeving and likely able to withstand the power levels of 4g63 but with much better
flow than any four cylinder ever made. No complicated mechanism cam over bucket win win.
6 speed manuals also available for FWD, 4WD and RWD presents prob the last Nissan beast L4 ever
Even Nissan 1.2 liter HF has massive ports LOL
