ok I have had this B17 bottom 1/2 for a while. was wondering wtf should I do with it. I was thinking about stripping the crank and build my B16 with it. or just parting it out. what do you guys think? or on building my B16 with B17 parts?

 

any insight to how well B17 parts will do in a B16 will be great appreciated.

 

how much u want 4 it???

 

Honestly no Idea. I sold my GS-R shell like 2 months ago. the motor still ran. sold the head to a friend who wanted to get LS/V. so the bottom end been sitting my my garage. I was thinking about swapping parts between it and my B16. Don't know how much of a difference it will make.

 

well i really dont think it will make a diffrence. so if u find out let me know.

B17A = stroked B16A.

for just saying this so you can get the bottom end.

If you use just the b17 crank in your b16 I think you'll be okay and have increased displacement --&gt; more torque

It all, however, depends on the setup. My old setup was gonna be a b17 crank with some oversized CTR's and a milled GSR head. I would have had a high compression, high revving motor.

You can PM chad, as he had this setup ^^ and described it "fun as hell" if my memory serves me right.

There's a good article on it above.

Finally, I hate e-dyno's because so many different factors contribute to the dyno and it's results but here you go.

I found my complete B17 shortblock with a fresh rebuild (0 miles) for $600 locally. After a few parts were swapped (CTR pistons) and it was assembled and broken in, it laid down 166whp and 119wtq. More then a stock ITR. So no, I don't think that in all cases the B18 makes more power. Anyways, point taken. Not trying to start a huge fight.</TD></TR></TABLE>

Good price for a freshly built motor. Wow that's a decent amount of power. What head and cams? It's true to a certain point, BUT if the two motors are identical the B18 will surpass.

P.S. I have three friends with ITR's.

1997 - 168whp stock
2000- 170whp stock
2000 - 171whp stock. </TD></TR></TABLE>


Just hang out in the all-motor forum for a little bit and do some reading

 

thx man. I kinda had the sme idea about the crank. but was thinking a turbo application with it.

 

i guess i might as well try... wonder how it will hold up.

 

maybe I dont understand but why not put the b16 head on the b17 bottom end?

Yea...but maybe use the B16 pistons in the B17.

 

The B17A is basically the exact same thing as a B16A, but stroked to 1.7L. North america is the only market to get the B17A so its considered very rare among the B series engines. The bottom end is sought after by people wanting to put them in CRV blocks to achieve a really good rod/stroke ratio and make high revving CRVtecs too, so they usually demand a higher price compared to B16A parts.

you can use the B17A crank/rods/pistons in any B16A block to stroke it to 1.7L. the B17A is a "square" motor in that the bore and stroke are about the same (81mm). more torque than a B16A, but with as good rev-ability. its a win/win situation. Although I'd use a B16A piston instead of the B17A piston for more compression.

A really cool setup would be to sleave your B16A block to 84.5mm, and throw in some custom pistons along with your B17A crank and rods, and some nice aftermarket cams/valvetrain. that would get you a nice ~1.9L engine.

 

never really thought of it that way. 1.9 liter B16a. i wonder what the numbers would be like. I might try that.

 

lol the more i think about it... 1.9L B16a. wouldn't it be around the same price as buying a B18C..........

the only advantage i could see... was 7mm in clearance.

Good info, save for the "win/win" comment. It's best to remember that engine building is all about trade-offs. B16s are high revving but low displacement/torque. B18s are low revving but high displacement/torque. The B17 is less of a win/win and more of a compromise, but a good compromise nonetheless.

I examined the merits of this engine fairly indepth recently while deciding whether to buy a 92 GSR or not. For a build motor, the crank is really the only thing of great value. The rods (specifically rod bolts) are fairly weak, and the pistons are low comp. The best application would be a B17 crank, forged rods, and high comp. pistons in a sleeved large bore B18/20 block for a race application. It works out to a great little screamin N/A engine package.

 

sorta off topic but cant you use and LS crank in a b16 block, and B16 rods pistons? I think it must be bored 1mm over thus stroking it to a 1.9?? Whats the kit they were selling on HT a while back for like 600 ?
