Is there a specific way to time a motor that has vitaras? or can I just time it as if it was the regular pistons on there? I can hear the valves pretty loud and it gets quieter at certain rpms. What do you suggest? When I first checked before start up, I put everything tdc but somehow it wa way off, I fixed it to tdc but now Im afraid Im still getting loud valves but at a cettain RPM range.

And I saw a bunch of vitara builds and I wanted to be sure that mine is not too loud. How loud is too loud??? I will try to get a vid later on.

Yup OEM timing...

When you did the install, did you re-set your valve lash?

I installed them toward the belt as I saw in many forums since last year. I did not redo my valve lash. Should I???

They are supposed to be installed towards the flywheel side.
You're offset is on the wrong side with the pistons facing the Tbelt side.
One of the reasons they made the offset is to create a gradual transition from major thrust to minor thrust.
major thrust being applied towards the cylinder wall on the downward stroke on the combustion stroke and minor thrust being applied on the opposite side of the cylinder wall on the compression stroke.
That transition of force from wall to wall that the piston does creates a ticking sound.
Having a piston offset allows that transition to be graduate instead of forceful which aids in decreaseing the tick sound aka piston slap.
my .2

although a too large of PTW can cause piston slap even with pistons facing the right way.

I agree with DRFT you are most likely hearing piston slap due to installing the pistons with arrow facing timing belt

the piston slap may also be accentuated if you used standard bore pistons

Well, I think Im gonna put the pistons' arrow towards the flywheel and change my piston rings, cuz I think a ring broke during install. ( breather has some oil smelling smoke coming out of it.) Do I need to change the main bearings again? Do I need to do a valve lash? Thanks for your help guys.

Yes, the arrows point to the flywheel!!!
you could check your valve lash, and or re-adjust it, wouldnt hurt... and bearings yes if you are going to re-micropolish your crank... otherwise no it pointless unless they are bad, just put them in same place

Guys, Does anybody know if STD size vitaras use plain regular honda piston rings or do they make rings specific ones for vitaras? Im stuck in my build because FJ's website is down right now. Thanks.

Well can I just buy any rings that say they're for vitaras? because I dunno what year they come off of. Do you know? I need specifications just to know Im getting the right stuff.

Back from the dead with this thread, but updates: I went 75.5mm vitaras and engine sounds close to stock. I have the same question about timing though.

My idle sits at 1.2K to 1.5 K, but will rarely go down to the 900 it was setup at. Do you guys think its a timing issue? I timed the motor OEM. thanks for input.

BTW, I'm running it for break-in on my old tune, as I dont have the funds to get it tuned yet.

Waiting for answers. Thanx
