Noticed the engine code bottom end for SRI is A16LEL, VXR is A16LER
Looked up the specs
The SRI is restricted at 150bhp
The VXR is deristricted to 192bhp
I am planning on using a good condition SRI bottom end with a VXR top end all to go back into a 08 plate VXR
Will I lose any power or is it all the same engine and is only mapped by the ECU?
Or is the bottom ends different? I.e. Stroke type, making them more/less power
