Hey guys - RHD update... I had a very unfortunate issue with my 818... broken rings on cylinder 4! Damn!
So removed engine - relatively easy process after removing under tray and rear bumper, sent engine away for inspection. Ended up replacing all engine bearings (aluminium had scored crank a little), new O/S CP Pistons, rods, full engine clean and gasket set. Then decided to install a Mishimoto oil cooler (with added fans) - this was less expensive than replacing new OEM oil cooler, which likely had gritty deposits inside it? Just last week I completed the assembly and started the car. Whilst apart I opted for some new 1000cc injectors - they standard WRX ones were previously running at 85-90% duty cycle - so increasing the size will allow for more boost and bigger turbo if ever it is needed.
My 818 was tuned on the dyno today, and I'm very pleased with the 239Kw power @ 12-13PSI on standard VF52 turbo. Attached is the graph.
Final break down of engine...
2012 WRX 2.5L
o/s CP forged pistons
ARP heavy-duty bolts and head studs
Forged rods (Cosworth)
Cheap ex china extractors - these don't hang too low.
Standard WRX VF52 turbo
Cusco Engine mounts
New 2 1/2 inch exhaust no CAT single straight through resonator
MOTEC M800 ECU with cam control, wideband O2, DBW
Mishimotor oil cooler
Mishimoto thermostat (lower opening temp)
Mishimoto radiator
Very happy with everything - and very nice power curve (turbo does run out at 6500) but nearly 650NM torque from 3000 RMP
