Stroking the B16b


yes stock cam and is 91 octane fine for 11.5?

i have a p28 w/s200 laying around that i can get tuned.

the little extra bump in compression is nice.

are you using stock cams?

As others have mentioned, it would be best to have the car tuned via a programmable ecu.

Do you recommend the 0.5 buddy club head gasket? :nerv:
 
I don't see a problem with it, if you know the current deck height of your head and know that the gasket is going to bump the compression to a value you are aiming for.

Otherwise, and I have only done this for myself and close friends, I modify the stock gasket by removing the top layer and then using a light mist of copper spray, I bond the two remaining layers together. I DO NOT spray the surfaces that will touch the head/block.

It has held up remarkably well, and I have all the confidence in it to do it over and over again.

DO NOT remove the center layer of the gasket as it is the one that is responsible for diverting coolant properly.
 
If the b16b is in good working order, sell it, buy an ITR. Over here the price diff form CTR to ITR is less than $1000US, you'll spend way more than that converting the CTR into a Type R. Unless you can literally do all the machine work and assembly yourself it's going to cost more, and there's always the reliablity issue. The longer stroke LS crank leads to extreme speed and piston loading even beyond ITR crank. I wouldn't use an unbalanced GSR to spin above 8k. Why gut a perfectly good CTR.

We're not talking LS cranks though, TBH you are right the 89mm cranks are too long for a short block and really not meant to rev, which seems against the whole point of a Honda.

The Spoon kit is as close having blueprinted engine internals though, and this will be better than dropping in a used B18C of unknown history.
 
Sorry if the question can be trivial ... so the ITR crankshaft can fit also in a B16A2 block without having to make changes? tnx!

No as the B18C/B16B rods have narrower big ends and so B16A rods won't fit on a B16B/B18C crank, and you can't get B18C/B16B rods in the B16A block as the deck height is lower.
 
Thank you Kozy, my crazy idea was to put ITR crankshaft, rods and pistons in the block B16A2.... :angry2:
 
Yes, not possible I'm afraid, not easily anyway. You can weld on a deck plate to increase the deck height or get custom pistons with reduced compression height, both are considerable work and cost and it would just be easier to get a B18C.
 
thats deadly info but what are the prices for a stroker kit? would it not be cheaper to just swap for a b18c?
 
Usually yes, but then you are sticking in a second hand engine of unknown origin.

Stroking is obviously more, but you essentially end up with a fresh engine (if you do it properly)

unless you rebuild it with new bearings and rings.
 
For some reason I got LS crank in my head. You can't stroke the b16A for the above reasons. What you can do is get a GSR short block (same crank geometry as ITR), put the b16a head on, upgrade the valve train, get ITR rods/pistons, have the whole rotating assembly balanced and you have the "poor man's" ITR. I just hate the idea of sacrificing a perfectly good b16b. I'd much rather see a GSR and 16a sacrificed to achieve the same end.
 
Hi Guys,

i have a question to be ask, if follow my spec as below can anyone culculate the ratio i can get from the conditions as below?

- B16B engine
- stock head gasket:
- LS crank and LS rods with cp pistons CR12.5: =>result ?
- LS crank and LS rods with cp pistons CR11.5: =>result ?

Thank You.
 
What do you mean 'calculate the ratio', looks like you've already got it?
 
What i mean is if im not so sure on the ratio out me. like if used on B18B engine the with cp pistons CR12.5 so the ratio is 12.5 but if i used on LS crank and LS rods with cp pistons CR12.5 for B16B engine will i get the same ratio as 12.5 ?

Thanks
