For a GSR Engine, to modify it, what does anyone recomend? i was going for this below… 1. Type R High Compression Pistons 11:1 2. OEM Honda Engine Bearings 3. Type R Intake Manifold/Skunk 2 Intake Manifold (Which Ever is Better) 4. Short Gear S1 Transmission 5. Shot Peened Rods 6. Clutchnet Six Puck Clutch 7. AEM Cam Gears/Type R Cam Gears (Which Ever is Better) any suggestions would be good. if you know any other types of things that would be better for performance/horsepower please let me know:gun: ---

1. I’d recommend getting P30 pistons. They will give slightly higher compression than the jdm itr’s. The jdm itr’s in a b17a yeild 10.72:1 while the p30’s yeild 10.94:1. Plus the p30’s are a bolt on swap. the itr pistons will require that you shave the rods a little bit. not a problem or anything, just one more thing you’ll have to pay the machine shop to do. You can also opt for ctr pistons which will give you 11.36:1, these will also require that you shave the rods. 2. ACL bearings are also good. Dan (G2Guru, myself, and a handful of other members are running them) 3)I believe itr and skunk2 are actually the same. Skunk2 just made a replica…i could be wrong though. 4)🆙 5)🆙 depending on who you ask some will say you need them, some will say its a waste. I had mine shot peened just in case. arp rod bolts aren’t a bad idea either. 6)I’ve never dealt w/ clutchnet, so i can’t give any input on them. 1. definitely aem instead of itr. Itr cam gears are exactly the same as all other b series cam gears. If you’re not getting performance cams then i’d hold off on the cam gears, you probably won’t be able to extract any decent power from the gears w/o cams. Also, some people don’t like the aem gears because they only have 3 bolts holding them in place, compared to 4, 5, or even 6 on some other brands. ---

Call your local machine shop and see what kind of prices they can give you. Also, do some searches, there have been a lot of guys building b17’s recently so there is a lot of info out there…show some initiative, do a search 🆙
