K20c2 e85

[_jdavidfc4]

Which other tuning solutions are using? K tuner does ?

Maxx ecu is the only new tuning solution method to go e85 and boost for the 2.0 N/A. Ktuner and Hondata do not support the c2 route for boost or e85.

No point in going e85 unless you upgrade internals.

Such as rods pistons? First time hearing about this. I did not know about upgrading internals to go e85

The rod journals and piston pins are smaller on c2 vs c1/c4. upgrade to c1 crank and rods, and 8th gen pistons.

are there any other mods to be done to build the motor? Or is the list you mentioned enough to handle e85? (for future reference) .

Question. What are the capabilities of the c2 unopened? Like the reliable threshold of an unopened c2.

Probably 250-300hp 200-250 tq. Not sure u til someone tries.

4P racing head studs for type r
4P racing Ferrea valve springs
4P racing Ferrea valves (I know intake will work, I’m pretty sure the exhaust may fit)
4P racing type r oil pump may work
Iron sleeve
Port and polish
Cams? Ehh .. just up the boost lol

Incase anyone is interested in reading. I have been tuned on to run on 3 gallons of e85. No check engine light. No stalling. Car runs normal albeit with higher injector duty cycle. Injector duty cycle is at 80-82% which is impressive with 3 gallons of e85 on the stock c2 fuel system. No flex fuel available yet for the k20c2. Car is running very strong. No knocks. Fuel was 7-10% lean during WOT before the tune revision. No longer running lean with latest revision. Ignition looks very good running strong dead on. Adjustments to maf curve on high cam were made. Just need to get it on the dyno or ask my tuner to put in on a virtual dyno as it is also fairly accurate depending on how I do a pull. My car does pull harder forsure with the new revision.
I will be using fuel system cleaner and a dedicated fuel injector cleaner after every oil change to keep the stock fuel system reliable.

in my opinion this would be a safer route to get some more power than going full e85 and all its cons that come with it. Will report back once I get dyno numbers to prove gains made.
