ive bought a full stock LHD AE86 with an 1600 16v (125bhp)

what modifications can I do to have aprox. 150 to 160 bhp

want to stay NA

Before we begin... lets make sure all the numbers are correct.... the AE86 powered by the 4AGE came in 2 different mechanical configurations 9.4 to 1 (112-115hp), and the 10 to 1 (I've never seen an "official" hp listing for this engine, but I'll assume it is 125) ALL of these numbers are measured @ the crankshaft... not @ the wheels.

Assuming you have the 125bhp engine(10 to 1 compression pistons)...

A properly ported head, with shaved, deshrouded chamber volume of 34.5cc, radius back cut valves, with a proper 3 angle valve job, Web 294 grind (their equivalent to 256 type)camshafts, adjustable timing pulleys, and a decent 4/2/1 header.

The above modifications should get you comfortably into the 145-155 crank hp, or 120-130 wheel hp, running stock engine management.

how can u now u have a high comp version
