Power level of GT86 CS-R3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

brn12345 · 02-07-2022, 04:26 AM

I have been reading up on the GT86 CS-R3 rally car built by Toyota TMG and looking at the specs it says that the car makes 230-240 hp. The information i am sure of is that these cars use a Motec ECU, Milltek header, TMG intake, Camshafts (couldn't find if they were a brand or TMG's own). If you look at the videos below you will see that they are shifting at 8200rpm and the engine sometimes goes to 8400rpm. Does anyone have more details on how they achieved the 230-240hp? and if so is this something that we can replicate especially the 8200rpm.

What i'd be most interested in most, is how they got that 8400 rpm redline reliably on FA20 without running into oiling problems.

The missing piece that few outside of race teams mess with on our FA20 is the camshaft profiles. There is for sure power to be found there.

As for how they improve reliability at those RPMs

Maybe they strip the motor after every event?

They probably did some front cover porting and larger oil pump gear to get the oil pressure up. Didn't IAG and Element Tuning solve this? I remember Element claiming around the same power from their longblock as well. I doubt one could replicated this engine package for under $15K and then you are half way to a 2ndGen that makes the same NA power stock..

Didn't Element tuning stopped at 7800rpm, due said oiling limitations? Too lazy to search for those threads. But still, that high redline is what impressed me most. Even more so that it's actually (ab)used with race load, that should mean that reliability is there.

No, Element Tuning with their oiling mods went to 9000 rpm.

i 'm tuning a NA guy in italy, with Toda camshaft and titanium spring and retainer and he regularly gets to 8050rpm without problems.. i avoided higher redline though due to oiling reliability

Catless and with bigger cams, and enough octane the timings go up easily there in the high power zone

Do you have any pics of the torque curve?
