I have recently acquired badly knocking (sounded like diesel on idle) APY engined S3.
After taking engine off from car and opening oil sump, the oil pan was filled with copper/aluminium looking pieces.
3rd conrod end had turned to black and engine did not turn easily, not very big surprise because crankshaft and block were both twisted 5mm.
Parts so far:
H-profile rods
Wössner 8.5:1 pistons with new rings (pistons were on old engine, dont know why some owner had them replaced but they seem to be in great condition)
BAM engine block which I hone myself
SMF&SRE pressure plate and organic clutch disk
3" DP with 200cel catalysator
Adjustable FPR with bigger return line (straight fit to old fuel rail)
Parts to get IF turbo is a good choice:
cast iron T25 exhaust manifold
GTX2860RS GEN 2 with .64/internal wastegate turbine
1 bar actuator
EV14-630cc@3bar long spray tip injector
FMIC 600*300*76 3"
APR 265 LPH pump that should fit intank link here
I have been trying to find info about 2860 GEN 2 on S3:s but no such luck.
That turbo should be big enough and with somewhat good spool to achieve 400hp
Is the turbo really worth it? It cost 1450€ with full actuator kit and 5 bolt outlet. GT2871 would be 800€ approx full kit
apy has ME7 engine management, is this any problem for tuning/mapping it? What kind of job it is to change it to ME7.5 or any aftermarket ecu that fits right in?
