Simon used for the A12 160hp he used GT2860R (707160-5) ball bearing turbo (stock part from twin-turbo Skyline) on E85. Stock block, stock head gasket, stock and unmodified H89 head

id be using a T28 turbo or larger for the 150kw..

Your injectors will need to be bigger we were running 23psi T28 on e85 with 750cc injectors to make 212rwhp with around 22 degrees of timing with A15 fully built, decent cam all big head work is where the power is made.

We gone to a GTX2871R that will be making the high 200kw range


My other engine is being built currently for the sedan, Fully built will be running 750cc injectors and just 98ron custom cam all head work 30cc chambers 5cc for headgasket 1mm headgasket ect ect ect
But is running a Garrett T25 and be into the 20's should see the 140-150kw mark is running a smaller clutch setup and the W50 not built behind it be happy around the 130-140kw at the wheels with that build
