Like the the title states my SCAT rods wont slide inside the cylinder bore. They will go in buts its really tight and I don't want to scratch the bore. Its a d16Z6 stock bore with just honing done.

Would it be ok to sand down the edges of the rods just enough to get them to freely slide down the bore?


Thanks for any info.

it shouldn't weaken your ----, sand it and throw some clear packing tape with some wd40 to lube it down the hole

I don't think it would hurt anything. I'm only taking off a microscopic amount off each side. Good idea on the tape.

I don't think i'd do it. Will they actually touch the cylinder walls?

can't you notch the block? wouldn't that be a better solution?

b18a/b rod?

same lenght (137mm) but bore is bigger
same journal size
pin is 21 for b vs 19mm for d

sometime company like to take shortcut but they forget small detail

That sucks I'm going to measure the pin right now.


EDIT: just measured the pin holes and there 19MM.

just sell (i assume) the stock bore vitara

and buy overbore.

Setup quality will be better in the end with a better p2w

I ended up ordering SRP forged pistons. No big deal right now I'm going to work on it some more tomorrow and see what I can do.

You do not have to shave anything off the rods. I had the same issue when I was building my engine a few years ago. If you try installing them at different angles, you will notice that there is one point where they will slide in with very very little resistance. Once in the block you can rotate them to line-up properly with the crankshaft. Just lube the side of the rods, and the cylinder walls before you try installing them.

I'll give it a shot thanks.
