Does anybody know why this motor is much stronger this a b18c.. ... cuz im thinkin of swaping that but just wanna know more... an does anybody know why a lot of people say the b17 tranny feels better then any other

 

I don't think a B17 is stronger then a B18C. The tranny is shorter geared then the B16/ITR. They are just rare.

 

I'm not sure that the B17A1 is more powerful the the B18C. I'm interested to find out the answer though. I just had my B17A1 completely rebuilt and its running great so far. Expensive rebuild though.. everything on a b17 seems to cost more from what i found out. I had to pay a mint to Acura to get a head gasket for it. I have not hit the track though because I'm still breaking in the engine.

93' GSR B17A1

 

well, the b17 has a better rod/stroke ratio, making it more reliable at high rpm's

r/s isnt important.
its not stronger.
one of the best cable trannys though.

 

most of the parts are interchangeable between the B16, B17 and B18C motors.
i'm referring to the different gaskets, seals, bearings, rings etc. but some of the main internals are able to be swapped as well. for instance the B16A OEM HG is the same as the B17A HG, since they use the same head (PR3).

the stock B17A puts out the same HP as the stock B16A (160), but it does have a bit more TQ due to the displacement. but the C/R on the B17A is one of the lowest of all the DOHC VTEC motors, 9.6-9.7:1. whereas the B18C1 is 10:1 and B16A (USDM) is 10.2:1.

as was already mentioned the B17A is normally harder to find since it was only made 2 years. hence the parts may cost quite a bit.

as for the tranny, the spec sheet i have says that it has some of the closest gears of all the B series motors. but it is a cable like hybridvteceg stated.

 

the head gasket thing doesn't make any sense. it is the exact same thing as any other DOHC VTEC b series engine. you could order it for a 94 GSR or for a 2000 SI and it will be the same gasket. it is a good engine but definitely not better than the B18C.

 

Trust me I don't understand it either.. but there is a difference. I went to Honda and they told me i could not get it and refered me to the Acura dealership. I even checked aftermarket places and the only place that could come through with it was Acura.

 

that's brutal, they are just making money for nothing. next time you need a gasket ask for the 94 GSR. seriously, it is exactly the same.

 

i have gone to Honda a couple times to get parts for a B18C motor and they tell me that they can't even look it up in the computer let alone order or sell it.
they told me "you have to go to Acura to get parts for an Acura motor".

i'm like yeah it's the same thing but that didn't make a difference.

so now i normally order everything from Acura cause the guys there are much cooler (older bunch). if i need a HG for a B16A, i just go to Acura and order it cause it's the same thing. not only that but through a friend i get a discount as well which definantly helps. i only go to Honda if i know the part will be available sooner or may be cheaper. but normally the prices are the same or very close between interchangeable items.

so you can go to either Honda or Acura for most of the parts you need, whatever is more convenient or cheaper.

 

yeah, what sweet said...........

 

as a b17 owner, i would personally rather have a b18c. the extra torque is a way better building block not to mention the b17 is basically a b16 but with horrible c/r. hopefully within the next year some p30 slugs will see how the b17 reacts to some REAL compression...along with every other part ive used in my setup...

i guess i've had the wrong impression. i thought that the b17a1 was NON-vtec. am i mistaken? also, the b17a1 still uses the pr3 head casting, but in a non-vtec head setup? [given some info could prove that last remark false]

 

Huh? B17A is DOHC VTEC. Period.

hmm. i really thought the first dohc vtec motors [usdm]were the b18c1 and del sol spec b16a's. thanks for the clarification. i'll sleep tonight.

 

B17A/1
also known as the blacksheep of honda b series motors. I own a b17 and i love my motor, yet it has low compression for a vtec motor. I still feel this motor has good potential. But what this motor really needs is more cr and more displacement, but then it wouldn't be a b17 anymore. .

 

agreed...lets just say if it wasn't so rare, id probobly sell it for a b18c, or go lsvtec, but i just cant let go of her

 

it definantly is a good motor, just not as good as the B18C1 in a stock to stock comparison.

but with a few mods just like the B18C1, it can really shine.
i think the main reason why people sometimes covet the B17A is due to it being much harder to find when compared to the B16A and B18C1.

even before we had the B16A, B17A or B18C over here in the US, the B16A1 was available as one of the first JDM DOHC VTEC motors. i believe the NSX motor was also available around the same time period, possibly earlier. i can't recall at the moment.

What kind of Mods have you done to your b17?

 

Integra XSi had first introduced VTEC by Honda evne though they had been expieriementing with it years before. 92 USA saw VTEC in the form of DOHC and SOHC.

With CTR pistons and Cams the B17 makes some pretty impressive numbers.

 

you asked for it.

b17a: 3" intake, 64mm TB, itr intake mani, skunk2 stage1 cams, itr vavlesprings and retainers, jun header, test pipe/carsound cat, greddy mx exhaust, re mapped ecu (vtec 5400 rev limit 8500), no a/c, no p/s.

planning on either pr3, p30, or ctr pistons with mugen headgasket--possibly a bigger TB and ported intake mani next, must research first b/c the 1.7 is a little small for anything over 64mm. needed to install clutch, and get a 8.8 flywheel and shaved crank pulley...the list goes on and on.

 

i guess some of u guys actually know what u are talkin about and some of u guys just talking out of ur ****... well i just founded out that the b17a has good racing gear ratio and that most of the dc2 gsr parts can fit into the b17a.... .

yes the 92-93 GSR gearing is excellent, which i believe was mentioned above somewhere. also there are quite a few parts that can be interchanged between the DOHC VTEC motors, but remember that the B16A/B17A have the same deck height which is shorter than the B18C1/5.

They ARE exactly the same. ANY part for a B16 will interchange with the B17 except the rods and crank. The bearings, water pump, head gasket, head, tb, dist, oil squirters, flywheel, oil pump, rear main, etc, etc will all interchange. The gasket and timing belt are also identical. It IS nothing more then a stroked B16 afterall.

i concurr with everything that is stated here.
