They didn't on those BMW motors. If you watch the video, they even pissed on them. In F1 they have a set amount of motors per season to use and if they go over they get grid drop penalties.
Apologies for reviving an old thread, but with a few of the weaker 1.5T engines beginning to experience rod failures under higher boost levels, I have been feeling nervous about my 2017 SI with 23 psi basemap. Were you ever able to definitively determine what items had been beefed up in the SI block, and by how much?The part numbers are different, but there isn't much information out there about any differences. The Si block has been rumored to be stronger, but we cannot confirm this yet. From a monetary standpoint, though, the Si block is actually cheaper than the base 1.5T block!
Apparently I don't know right from left!Oops haha
That is a possiblity... We will see!
I read somewhere that si rods were forged but don't quote me on that
I do recall reading that. Are the rods on the EX-T not forged?
If you have seen Caraddicts new YouTube video, he stated that he might purchase both rods and do a comparison video to end this debate. They are different part numbers but that doesn’t mean they are superior. Although it would make sense in my opinion to make them stronger for the Si trim.
I agree that it would make sense, but somehow, I have my doubts that Honda made any significant changes to the SI's engine durability this time around. I would very much like to be proven wrong though.
Soooo.... i have to trade in my cvt EX-T for a SI if I really wanna get serious with power. Hmmm. I love my car but I will undoubtedly love an SI but i has this car for a year already. I don’t mind paying extra but I don’t wanna be one of those people that trade in cars excessively. Idk what to do.We figured that it's only a matter of time before somebody pushes the 1.5T platform to the max and know that we will eventually need an engine with forged internals. We decided to follow suit with the rest of the platforms we're involved in and develop a motor program for the 1.5 Turbo.
We will be using brand new OEM Honda Si cylinder blocks, crankshafts oil jets/squirters, gaskets and hardware.
2017+ Civic Si block
Notice the coolant passages at the tops of where the sleeves intersect. Also notice the aluminum cast around the top layer of the iron sleeve.
Main caps; no main girdle here. Honda's past K-Series motors featured a factory girdle system.
Awe look how cute! 73mm Si 10.3:1 compression piston.
The factory piston features a narrow piston skirt with a unique "spotted" friction coating.
These pistons also have quite a bit of material between the rings; A rather beafy design.
Such a cute little factory connecting rod!
M6 rod bolts
The rotating assembly can ALMOST fit an a USPS Large Flat Rate Box!
The left side is a 2.0L Type-R connecting rod, right is a 1.5T Si connecting rod.

Our goal is to offer a short block capable of holding ~500 whp. The build will most-likely consist of forged H-beam rods and forged pistons. We will be working to develop a drop-in piston set designed to mimic Honda's factory piston design. This will be extremely important for fuel atomization and combustion with the direct injection system. A ~10.3:1 compression ratio is a rather comfortable number for us as well, as it's high enough to keep turbo spool and response there, but not high enough that we are worried about detonation/knock issues.
We are also sourcing/developing a proper head stud and other components to be able to hold the power as well. Please stay tuned!
Stay tuned!
Fucking A. You're putting so many worries to sleep.Rods and pistons are in the works!
This is great news! Would you happen to have any perspective on whether the Si Rods and Pistons are any different that the EX-T ones? Wondering if an internals upgrade should be top priority for anyone looking to increase power significantly.Rods and pistons are in the works!
