Hi.

I have questions about that setup and i hope to get the answers here.

Does this work so far ? Could i take b17 crank and rods in my b16 block ?

What should i go, if i want to create a 11.5 cr ? Which pistons do i have to choose...b16 pistons with 11.5 cr...?


Is there anything else i have to notice going with that setup ?

Thanks in advance !

Greets,

Benny

Mr Hammond

Yes you can. B17 crank and rods w/ CTR pistons will be 11.3:1 w/ stock headgasket and valves and no milling or decking.

I am currently building this right now, however I am doing resleeved to 85mm and 12.6:1 compression pistons.

BennyS

Yeah,

i will also resleeve to 85mm but only going to 11.5 because i heard it's dangerous going further with stock electronic.

So i can get any B-series pistons with any cr and create the cr it they are build for ?


Thanks for fast reply

markdman

so why not just use the stock b16 crankshaft?

Anyhow, a clean B17A crank and B17A rods, plus 85mm pistons in a sleeved B16 block, around 11.5:1 or more would be AWESOME!

That's exactly what i'm going to do

In my case a stock B16 head will be used.


I'm wondering how this combination would work with some stage c cams from toda concerning valve to piston clearance...?

</TD></TR></TABLE> so essentially you can consider the setup a B16 stroked and bored, which would be awesome yes.
piston to valve clearance is not usually an issue as long as you order your pistons correctly... 85mm pistons will not be oem so make sure the piston you choose is okay to use with high lift cams like Toda C, and do NOT use oversize valves!

This is what I am doing right now. RS Machines B16A2 block w/ B17A1 crank, Crower's, Arias 85mm 12.6:1's and a Portflow PR3 head w/ Skunk2 stage 2's and valvetrain.

BennyS

So it depends on how the pistons are designed.

But what im gonna looking for ? Highdome pistons create a higher compression. So...which requests they have to fullfill ?

Thanks,

Benny

thats the exact same setup that i have right now, except for the cams and valve train, but unfortunitly due to some poor workmanship i had to get another block sleeved so it won't be up and running again for another month or so.
MR. Milano, how much longer until your motor is togather and running i would like to know how it works out for you, what you like and don't like about it, just stuff like that.

Mr Hammond

This going to be a winter long project. My only goal is to have the car up and running to par by March (beginning of next season.)

I'm still waiting on my 10-94 header and there will be as an extensive write up as I can on that. (I haven't forgotton)

And I am documenting this build-up so there will be a write up and results.

mr. wu

sounds awesome man!

Screamer

So what is the exact rod ratio 1.62 right??? I am planning on doing the same buildup, but I am woried that the rod ratio of 1.62 is still not worth the whole project. What do you guys think?

Mr Hammond

Are you serious? Who cares? I'd run it right down to 1.5:1.

Drag-On

what is the advantage of having a square motor which he would have with b17 crank and rods and b16 pistons?

I know this thread is way old and all but I need to resurrect it since I found this via searching for this topic and I don't want to waste time by making another thread and have folks tell me to search for the topic. Anyway, over the past month and a half or so I've been looking at doing a poor man Type-R setup on my 99 Si after finally deciding to just go all motor with my little 'ol Honda. I had planned on starting it this winter or so. Engine-wise, I have modified the car with the following items: AEM CAI, DC Sports JDM 4-1 header, Skunk2 IM, stock throttle body bored to 64mm, and a APEX'i N-1 cat back exhaust. At the end of March I am having installed Skunk2 Stage 2 cams, Skunk2 valve springs, Skunk2 Ti retainers, Skunk2 cam gears, and a Hondata s100 that are currently in my garage after scraping together many pennies and alot of extra overtime at work. The original plan was to do this and then this winter hunt for a B18C1 block and have it built with CTR pistons. Next summer I had planned on putting on ITBs (TWM 2000 series) and calling it quits with it. I had hoped to achieve 195-200 whp with this setup.

I had thought about stroker kits but looking at the prices of them (i.e. Toda, Crower) I thought it was a waste of money to go that route so I thought it would be easier to hunt down a GSR block and do that. I didn't really want to get rid of the B16 out of the car but it looked like I didn't have a choice. Then someone told me to look into a B17 crank and rods. That's how I stumbled across this nugget of info. So would this really be a reliable (and cost effective) option for my car? It is a daily driver so reliability is a must. I would like to see around 11.5:1 or 12:1 CR for it and to keep with the same WHP goal I listed above. I'd like to keep the stock bore but if I have to bore it, I wouldn't go higher than 84mm. Even if it makes under 195whp, just to get it in the 190s would be nice on a B16 all motor. Also, what exactly would I need to get to make this work? Can I just go to the local Acura dealer and order up me a B17A crankshaft and set of rods? Is there anything else I would need besides this? If you can give me any sort of help on this, I will name my first born after you. Anyway, thanks for the help ahead of time. Peace.

ironmonkee

Sorry for the fast repost, but here's a diagram I dug up on a Acura dealer's website:



Would all the things I need be item numbers 26 (rodx4), 27(rod bearingx4), 28(crankshaft bearing), and 29(crankshaft)? Am I missing the boat on something? Let me know. Thanks.

What exactly is the advantage of putting a B17 Crank in a B16 block? I know it increases the displacement, but doesnt it just increase the displacement to 1.7l? So you could achieve the same results if you just used a entire B17 block/bottom end? Or am I missing something?

SkRiBLaH

B16A block is IDENTICAL to the B17 block. ONLY differance is stroke.

ironmonkee

Can anyone help me out with this? Thanks.

Yes that is all you need. The blocks are identical so the crank and rods will drop right in. If you read up it was either this one or the other B17A post I posted my set-up and my plans. I am in the process of building this motor now.

Thanks for the dirt, man. Would the factory rods work just fine or should I look into some aftermarket rods? I'd like to just run CTR pistons on this with a stock bore of 81mm just to keep the costs down, but I don't think I would reach my goal of 190-200 whp with that setup unless I added ITBs. If I were to go with a bigger bore piston (84mm) and a higher compression of 11.5:1-12:1, can I still use the factory B17 rods or would an upgrade to aftermarket rods be required? Anyway, thanks for the help and good luck with your setup. I would like to hear more on this since I think this will definitely be the way to go for me. Thanks again.

With a B17A w/ CTR pistons and Skunk2 Stage 2's I don't think you'll hit the 190-200 whp mark. With headwork and good tuning it is possible. To be quite honest I dont' think you'll gain much with ITB's in the peak power department. If you sleeve and go 84-85mm and 12:1 compression, headwork and tuning you should hit the 200whp mark with quality bold-on's of course. Atleast a top name header and equal exhaust. Your stock rods would be fine up to that mark. Just get some ARP rod bolts. Depends if you want to spend the money for extra ins or not. I will be doing a lot of HPDE's and some drag racing. I am doing it for extra insurance. Any other ?'s lemme know.
