I am with you on the rods being a weak point (and needing to be mindful re: when you request torque with the stock turbo), but even the MHI stage 2 you referenced (which is, to my knowledge, the smallest aftermarket option for this platform) won't start to spool until between 3.5k and 4k rpm (assuming a stock head), which is generally considered safe for higher torque requests on this motor. So, you shouldn't need to tune in "fake lag" to avoid a low rpm torque hit with it.No not at all. I dont go there anymore.
I see the advantage of having better mid and better top end. At the cost of a little lag. The k20c1 can’t take too much tq in the lower rpm’s without the rods un-rodding themselves
think stage 2 turbo(or even the stock unit). The one that’s slightly larger than the stock one. Add fuel upgrades. Delete the cat or go high flow cat. E85 tune. That kind of tq down low is something the stock rods can’t take. Sadly
would’ve been nice to have either forged rods. Or even stronger rods that aren’t forged but can take a greater amount of tq and (modded)abuse.
I stand by what I said. Respectfully of course cuz I’m not trying to be a bitch. The ea888 gen 3 and 4 are truly the modern day k engine. Hell, the 5th gen is literally going to have a variable geometry turbo. I have a vgt on my 2025 s5. It’s fucking outstanding. If you’re near Denver we can meet at a parking lot and U can drive the s5 so U can feel it. It is freaking amazing
never tuned a k20c1 but have seen pics of the tables. It seems like it’s tq based (fucking finally) instead of boost based. Reminds me of how the Germans do it
A turbo swap on this platform generally helps to solve -- actually it doesn't solve it, more so it works around it -- the weak rod problem, as opposed to creating or emphasizing it, which is how I had interpreted your earlier comment.
VGTs are awesome!
