sup guys, i need some help figuring out what size belts i will need for this build i have. this motor was thrown together by the spare stuff i had laying around the garage so bare with me. the main info on the setup...
-b16 head type r valevetrain
-ls block
-gsr crank

any ideas? this is my first actual build from the ground up, so im still learning. i tried to search but i couldnt find much with a ls block and gsr crank.

ls block, should mean ls belt, but if i remember, that is depicted by that water pump. i would do an ls pump and an ls belt.

rmcdaniels

GSR belts, assuming a VTEC water pump. LS block is the same height as any other B18 block.

bnut510

yes its with a gsr waterpump. ok so is it ls or gsr hahaha. i need help! thanks for the replies

rmcdaniels

GSR pump = GSR belt


LS pump = LS belt

That said, use the GSR pump if you're using the GSR crank, the LS pump is meant for lower RPM applications.

nothing odd bout this build... its been done a million times

agrn93ls

use matching water pump and timing belt. ls pump=ls belt gsr pump=gsr belt

crank makes no difference. the gear on the crank is the same for ls and vtec

alright cool, thanks for the help!

i might as well ask about this now.. i put on the gsr oil pan last night on the ls block. i took the gsr pick up off, but it had this big piece of metal it was bolted on to, and that piece was bolted with the botom connecting crank piece (excuse my lame termage, as i dont know what that piece is called lol).. anyways i took that off and put it on the ls block but i had to take those bolts off the connecting crank piece. u guys know the torque specs those should be at?

added to favs. i did not know about lower rpm applications.
great info. thanks for the clarification.

The GSR has a main bearing cap bridge, that's the big metal piece that bolts on top of the middle three main bearing caps. The LS doesn't have one, so you need to use an LS oil pickup, or I think that a B16 pickup will also work.

ls - b16 pick up so far i have seen are all the same... i might put them 2 side by side for a through analysis thou

ok so the ls didnt have the bearing cap bridge, but i put the gsr one on there. along with a gsr oil pan with the gsr pick up. are u saying i need to run a ls pick up? sorry with my confusion. and still wtk about the torque specs.

rmcdaniels

To do that you'd have to use the GSR main caps. Main caps are not interchangeable, you need to use the ones that came with the block, Unless you get them cut and get the main journals bored/honed, but I'd advise against that, too much opportunity to get the main journals a little off and cause all kinds of problems.

rmcdaniels

Using the wrong main caps will result in main bearing clearances being off. Just a few thousandths in either direction will cause your motor to self-destruct.

yea if your terms and my understandings are the same, then thats what i did. i used the gsr main caps. i was scared i was going to get dirt into the bearings to..i highly doubt it but im just trying to be as safe as possible. thanks for the helpful infos

dont think you can just put the GSR caps on the LS block and be ok. i wouldnt do that. but i dont know exactly what you have to do to put a GSR crank in a LS block has anyone said anything about that fact yet?

bigbadboy

why don't you use a LS crank?? unless u don't have one. with the GSR crank all you are doing is destroking it some. the GSR crank will just drop it. just use the LS main caps and such

rmcdaniels

Exactly, use GSR rods and it should be fine.

reason y i didnt use a ls crank was because i didnt have one laying around. this motor is my first actual build from the ground up and im using scrap parts i have laying around the garage. with that said... im about to slap the head on thursday most likely and i was wondering if i can use the gsr head studs on the ls block? thanks for all the helpful replies btw

Smoke_em

YEs GSR head bolts are the ones that will work . I would'nt recommend using them if you have used ones "laying around".
