          first do a leak down and cp test. it can be done on a stock block but i would atleast get arp rod bolts and head studs and a good tune

          300whp can be done 350 is pushing it

            im tearing the engine completely down and rebuilding replacing all seals and bearings and pistons.. i spun a rod bearing is the reason for the rebuild

                i think your better off to get a b18 block. as far as i know theres no choice in rods for the b17.

                  the piston choices are the same. 81mm bore.

                  if you spun a rod bearing, you're going to be checking the crank yes? i would not use it, but that's just me.

                  the cheapest solution imho, would be to just get some forged pistons, arp rod/main/head bolts/studs, new rings, and new seals/pumps/etc. stock rods are fine IF they aren't damanged by the bearings spinning.

                    I would suggest that you go .25 or .40 over on the block to make sure your bore is stright and round.
                    The b17 rods are great but I wouldn't count on them being reliable at 300-350 whp however, the stock pistons would do just fine at that whp level if you maintain the stock b17 low compresstion ratio.
                    Being that you spun a bearing, you should think about geting the block line bored and the crank checked, ballanced and micro polished.
                    -ronie.

                      Stock pistons will be fine on lower boost, they're 9.6:1 stock CR which is decent for boost, i'd keep it 10 PSI or under though. Thatll save you some money on pistons. A completely stock rebuild, with maybe some GSR cams and a better intake manifold and a decent little turbo setup on 10 psi with a good tune, and youi should easily see 300. My all stock B17 made 241 on 6psi UNTUNED. and it was bone ass stock with 450cc injectors with a VAFC running it a little rich. I took all that crap off the car immediatly since i bought it like that and the guy had JUST put it on the car 1100 miles before i bought it.

                        B17's already come with gsr cams.

                          I meant from a B18C1 or something of that nature, they're not the same are they?

                            b16/17/18 all use 81mm bore, and im sure theres quite a few options for pistons for all these motors, why wouldn't there be for the b17? ...

                                  stock b17 compression ratio is 9.7:1.

                                  stock block turbo honda bseries engines are making 300whp + all over the country. it's not an issue. upgrade the rod bolts.

                                  pistons should be switched to a forged unit, tehy have deeper valve reliefs and would allow for larger and high compression valves with less issue, as well as allow a larger camshaft to be used. woudl also allow for more timing adjustments.

                                  no one has ever checked for sure but it is speculated that b17 and b18c1 camshafts are the same, as power gains when installed into stock b16s are the same. differences may be small enough to compare to the differences between the 97 itr cams and the 01 itr cams.

                                    so basically what i should do is have the crank turned and trued/ balanced and drop in some forged pistons and arp head bolts with a cometic head gasket and boost it to around 10lbs?

                                      im just new to the whole turbo setup and trying something small for now and i dont really have to much knowledge on the b17 in fact didnt even know there was a b17 till i bought this car

                                        don't forget arp rod bolts. and i would ditch the cometic headgasket for a stock one.

                                        i boosted 300whp at 18psi on my stock b18a1 for a little while. so with that done you shouldn't have to many problems.

                                          DO NOT TURN THE CRANKSHAFT! under no circumstances shoudl you let a shop do that. if they can't micropolish out the imperfections, and keep it withing stock honda spec, get a new crank. don't risk it. turning the crank means material is removed form the journals. unless its a shop really familiar with honda cranks, i would not let it happen

                                            i agree 100%. get a new crank oem and get some eagle rods cp pistons arp head studss and golden eagle HG. if you go bigger bore if not just get oem HG. ive made a lil over 400 on stock b17a but your always are pushing your luck. The build i just typed will handle 450 easy with great tuner. Please dont cheap out get new oil pump water pump all gaskets etc.

                                                i must say stock head gaskets hold up pretty well! and stock head gasket being metal, thats awsome! lol

                                                  Yea just swap in a b18c, save the b17, build it and throw it in later, I know you don't want to ruin a b17 block.
