Pretty much my thoughts. I'm content with where my Si is as a DD with FBO+TSP Stage 2... Once the market for our engine matures I'll upgrade the internals and stick a big boy turbo in there.
I went with a custom tune instead of stage 2 because my fuel trims and af ratios are dialed in better
The high TQ at the initial is what kills the motor. Instead of having a spike the 27w Has a linear curve. Just dial the TQ at higher revs.Oh for sure. I know with the 27won turbo it seems more safe to hit the 300 range since you're making more power up top than down low and I think Derek said that's what kills the rods is all the power down low, which makes sense. I ran 10 psi on my old D series with a t3/t4 turbo and was pushing the 300 range on a stock block before eventually the rods gave out, and they took a good year of beating before that happened. Eventually I built the motor and went with 16 psi and some head work and managed 350whp.
These little Honda motors can take a beating. But, it's so scary to think about blowing a motor on such a new of a car
Thanks man. Its nice to be driving in second gear at 20 mph and then floor it and have my tires spinning haha
Thank you! For the time being, I am happy with the power. Eventually i will go 27Won upgrade. Gave a Challenger 392 Scatpack a good run
Just to let you know, he threw a rod last year, around October. His "new" engine is currently stock, other than that he may be running TSP's Stage 1 tune
Considering their dyno is infamous for reading around 12-15% higher than most dynos, he blew likely only making 240-250whp. Might be an important tidbit for people looking to push the limits of their stock blocks.
