What are some negative effects of stroking a 1.6L B16b to 1.8L

 

side load on the cylinder walls. not as "stable" at higher rpms.

IMO go with a 87.2 crank instead of the 89 ls crank.

unless you plan on building the head and revving the **** out of it all day long, just stroke it out y0!

or get a final drive and increase engine cycles per minute

Im thinking the spoon stroker kit...onlt not the kit and piecing it together that ways its all OEM parts. Now will side load on the cylinder walls kill my logevity of the motor. For instance will it only last 3 years instead of 5. I only drive my car about 10-20 miles a day but they are a spirated 10-20 miles.

 

the spoon kit is nothing but a balanced gsr crank.

Think about it like this. If you have the same block as a b18c5, and then convert it to b18c5 spec. That's OEM. that's comes out to like a 1.58 r/s ratio or some ****.

d15's are 1.59, d17's are like 1.45, h22's are like 1.57 or something, d16's are 1.52
ls engines are 1.54

if it were an issue, you'd hear of gsr and itr owners having to rebuild their engine frequently.

IMO, a final drive would give you more "virtual" torque and be easier to install

 

I am actually awaiting the final drive from infinitude...but the strking was going to be my winter project.

 

the benefit of strokin would give u better torque at lower rpms, but in the end you wont rev as high. A spoon kit is fine tho, its "balanced" after all.

So i wanted to rev then i could build the head. Bigger cams new valve train correct?

yes but im sayin in the end the rod/stroke ratio wont be like the small stroke on the bottom end, still limiting the rev factor. I mean if you wanna stroke this thing to 1.8, you can still rev ur b16b to 8500 depending on the kit.. like the spoon kit.

 

Cool...im really just interested in making my motor more streetable. Right now its fun from 5k on in every gear but below that its nothing special. However getting on freeways is a lot of fun. Just want a little mor umpf off the line without going FI

 

Id keep that short stroke. Its nice bein able too rev in the 9-10k range. Get yourself some good cams that will help you carry torque into the higher rpms, a good header, port the intake manifold, maybe nitrous for that little ripper.

 

I thought about spray...but wasnt sure. I dont know much about it...suppose i could always read through the archives

The limiting factor isn't the bottom end on the B16b or B18c. It is the head. Better valvetrain and cams and you can rev a stock block to 9k without problems.

 

Oh yeah no doubt about that, its been done thousands of times. Im just saying i like the high rod-stroke ratio of the b16b motor. Its just a personal thing. Its damn good engine geometry.
