Has anyone hear of what all need to be done to fit a 1.8 crank in a 1.6?What pistions can I use,rods, ect. ? I have been looking for a straight answer for two weeks and have not gotten one.

 

Are you referring to a B16a block? And using a b18c or B18b crank? If so then I would assume you would need a deck plate to accomodate the longer stroke on a shorter deck. If you're referring to a b16b which is a b18c block that has been destroked, then a b18c crank will pop right in.

 

by stroking it out... will the b16 block with the 1.8 displacement have as much torque as the b18's ? will it have more HP too? is stroking it to a 1.8 better overall or just get a b18 block?

 

putting a B18 crank in a B16B would pretty much just make it a B18 bottom end. the displacement would still be the same

 

dude i asked a simalar questions about 2 days ago. It should still be with in the first 5 pages.
If you wanna get a stroker kit for the B16 then go with toda or JUN. Don't half-*** it for your block will end up to be a big heavy paper weight!

 

Don't waste your money on aftermarket stroker kits. If you really want to stroke your b16 then turn it into a b17 w/ OEM honda parts for a fraction of the cost of the aftermarket strokers. All you need is the B17 crank and rods.

 

so performance wise it'll still be the same? cause i plan on stroking it out and then going tubo afterwards, boosting at 12psi.

 

I would think a LS/Vtec would be easier, cheaper and make more power.

Considering you can get a B18 bottom end for about the same price as the crank you need to stroke your B16 and I'm sure you were planning on good rods/pistons anyways right.

BTW the rod/stroke ratio would be about the same on either motor anyway

 

Sure get yourself a $200 b18a block from the bargain bin and just paste your b16 head on there...you'll make lotsa gobs o' power. Least until it needs to be rebuilt in a few thousand miles, if it lasts that long.

I found a b17 crank & b17 rods for $182. If you're patient they're out there. Now even if you paid $500 for these parts, I'd personally much rather have that then build a frankenmotor. The b16 is a good motor, it just has a very conservative 77mm stroke. With the b17 crank you're increasing this to 81.7 while keeping a superior Vtec crank and not making a huge sacrifice in engine geometry. The result is an engine that revs nearly as freely as a b16 but has a torque infusion.

A b17 has an r/s ratio of 1.62 while the frankenmotor has an r/s of 1.54.

 

yea, I'm still looking for a b17 crank myself.

How you like it anyway? I'm curious as to how much power it can put down.

 

i was thinking of sending it to IB for their b16 sleeved package with the CR at 8:4:1.... dont really want to get an LS block or anything like that..dont like frankenstein ****.

 

Sounds interesting. Are these B17's from the 93 GSR? Drop right into a B16A block? B17 crank and rods, which pistons? Any dyno numbers?

 

'92-'93 GSR yeah. Yes. Whichever pistons you like. Since it's a B17 motor when you're done power will be the same as a '92-'93 GSR assuming the same compression. I believe the cams are roughly the same lift & duration. There's a great article on this topic located here:

ditto to that bro. Infact i was just taking to jeff about this. In November he's installing my motor for me. It'll be a "package 1"-B16a1 rebuilt
but to my spec of having it bore & sleeved to 85mm= making it a 1.8 and getting 11.1:5 CR. According to jeff, the 85mm should bump up my torque to about 130ish to the wheels and with that piston 8 size with STOCK cams i should see about 175ish whp.


I'll be happy for a long time. After about 2 years i'll add in the TODA stroker kit and and get my sleeves honed to 85.5 for my new pistions. ........ all i can say is
"CAN YOU SAY hello 2.1 liter dohc vtec?
with the stroker kit it should see about 150-155ish torque and 200whp (with STOCK cams)

throw in PortFlow head, JunIII, hondata some other goodies and you should see well over 220whp.


BUT it's really expensive. Not worth it to some people but for me it's a longterm goal (atleast 4-5 years to complete) You could just Do B16a turbo at 6psi and make about the same, but it's up to you.

 

Sounds good bro. I'd probably scratch the Toda stroker and go w/ b17 parts or an engine swap at that point though. The $$$ they want for an aftermarket stroker kit would go a long way toward an engine swap. You could probably get a pretty penny for your worked b16 and switch to a b18c and have more potential.

 

Yup the toda kit is about $2,400 oooch
yeah i though about that too:

B18c1= 1.8
toda kit = 2.0
bore to 85mm= 2.2 dohc vtec with a nicer r/s ratio than the H22

I'm thinking it should carry the tq longer than the H22.

I'd go w/ 86mm if you want more displacement than a 2l b18c. The cost to go to 86mm would be $100 more w/ GE and won't increase piston speeds or lower your r/s ratio. It wouldn't be a 2.2l, but I'd "settle" for a 2.026l for a couple thousand less. I guess I just dislike long stroke Honda motors. Plus then if you still wanted more you could drop the compression a bit and supercharge it for little more than the bored & stroked motor.

 

So a B16b is a 1.8 that is destroked, but the b16a and the b17 have the same deck hight. Is there any thign else that you can do to stroke the 1.6 out using honda parts or is it only the 1.7 crank

Well the difference in cams if there is one is tiny. If you're replacing your b16 cams w/ OEM Honda then get CTR/CTR or CTR/ITR intake/exhaust respectively. The main benefits of the b17 crank & rods are +4.7mm stroke & +.5 to static compression w/ b16 pistons. It's a good deal, plus there's nothing stopping you from sleeving and boring the b16 later. 86mm stroked b16 anyone?
