I used LS bearnings on my LsVtec and I can't sleep at night, because aparently the VTEC ones are different (different as in better) does anyone know what the exact difference's are and what mods I need to make to my Ls rods to accept GsR bearings?

 

u need to have your LS rods notched out to accomadate the gsr bearings which are way better good luck

 

way better how?

 

you should specify what you mean, cuz i didnt know if you meant main or rod bearings...

You are safe by using ls bearings for an ls block/crank, etc. as long as the oil clearances are within specs.

 

the gsr rod bearings are better than the ls rod bearings that have a special coating on them.

and u need to take your rods to a machine shop to get renoched to accept gsr rod bearings

You should not post information like this unless you know it to be true.

so rod bearings for a b17 are a good bet when going LsVtec?

 

if you are havin this much worries...just get an ACL set.

 

well said...

 

We are talking about putting GSR bearing into a LS motor mister.

 

GSR and LS main bearings are the same, GSR and LS rod bearings can not be interchanged, LS and PR-3 bearings have the same dimensions (can be interchanged) except there is no oiling hole ( for the cyl wall) in the PR-3 have seen no problems using them.

 

The subject is rod bearings and yes the rod bearings can be interchanged with minor machine work

yes you can use gsr rod bearings on ls rods
i myself am in the process of building my lsvtec and i had my ls rods renoched by rs machines to accept gsr rod bearings with the special coating on them

 

Thank you very much. Some people just dont knoe what there talking about.

 

Why would I buy a set of ACL's?
I'm personally a fan of OEM honda. I like the ability to chose my clearances. Do the PR3 bearings have this special coating? Can I use the P61 bearings? Are they the same as PR3's?

 

Look despite of what some people say just run a honda bearing and even better on your ls/vtec run a gsr bearing like i said just have the machine shop notch out the rod and youll be fine. I knoe because I do it all the time. As far as acl common guys this is your motor your talking about dont be cheap on the most crucial part of the engine mainly the daily drivers.

 

Thats my thoughts exactly, and I get OEM at cost (air guitar). Although the short block is together now with Ls rod bearings - This better not be a problem, or else them blame will fall squarly on Honda Tech's shoulders for not messaging me sooner!
A friend of mine is building his LsVtec over the winter though, you think I should tell him to get P61 bearings?

 

Well as long as you are running Honda bearings in your motor and it was put together rite then you shouldnt have a problem as far as your friend just use the pr3 mains and gsr rods for the ls block if you cant find a machine shop that can make the gsr bearing fit then give Rs a call I go there for all machining needs

 

Well I ran LS bearings and the motor now has 31K on it and gets spun 9300 rpm on a weekly basis . If you have the oil clearance right then there should be no problem .

 

thats what I like to hear!

 

i think that the reason for the coating on the b18c rod bearings is to help with the smaller surface area of the thinner b18c rods; to strengthen the b18c crank for higher rpm use and higher output, honda made the pin journals on the crank thinner, which necesitated thinner rods. this means that more force is distributed across a smaller area, so without the special coating which helps retain oil, more oil would be squeezed out at higher rpm, making it more likely for bearings to 'stick' to the crank and spin.

 

if you motor is already build with the ls rod bearings i wouldent worry about it
but if the motor is already apart and being build i would definatly get the rods renotched to accept gsr rod bearings

actually, hes right. you must renotch ls/b16a rods if you want the gsr/type r bearing to sit properly, in the center. if you dropped the gsr/type r bearing without machining, the bearing would sit way off to the side, uncentered, not good for oil contorl.

 

thank you very much Earl isgetting really upset and still arguing with me about this post.earl (3:03 AM 12/24/2003): If you never have used an ACL bearing, how can you say they suck? ACL's suck because you have never had a problem with Honda bearings. Great logic.
Well I have never had a problem with ACL so that proves hondas suck You amaze me.
spin2win (3:20 AM 12/24/2003): well reason that i say that they suck is from seeing from others and also at rockwell a few years ago we had a test with cams (jun) at the same time i wanted to have the two bearing differrent bearing tested along with the cams and the engineer told us that the acl bearing consisted of cheap material compared to the honda thats whyy i told you i would never buy a acl bearing
spin2win (3:29 AM 12/24/2003): look Earl you gotta look at it this way we are both engine builders with the same concept you wanna go fast turbo i wanna go fast aspirated maybe the setups that you use acl bearings would work great but for me most of the motors i deal with see the street everyday and after testing of two different bearings im not gonna be cheap and let a guy drive away with a cheap bearing you gotta remember these are Hondas not v8 these imports are very sensitive machines. but like i said there will always be critics like I would prefer JE but then other cheap people will say they like wiseco because it works for them and they get it for cheap or for free but deep down inside if the the other person is educated but refuses to believ the truth because again they just wanna save money or just dont have a budget to run the best
spin2win (3:34 AM 12/24/2003): Thats one thing i see with all motor guys they try out the best and use the best product to there ablity thats why you will see the Aspirated cars go just as fast as most 9 sec. turbo cars for 2004
spin2win (3:37 AM 12/24/2003): thats both sad and good turbo cars running 9.30s (unconsistently) and a aspirated car running 9.80 9.60s consistently
earl (5:42 AM 12/24/2003): You are either a complete idiot or the worst liar there is. You cannot bs me about certain things so why bother. Tell me one thing about how acl's are made. Tell me one thing about how honda bearings are made. Tell me thing that is similar about how honda and acl bearings are made. Tell me one thing that is different about how honda and acl bearings are made. Do you even realize that ACL is one of the largest bearing manufacuurers in the world. Not that that makes them any better but just the fact that they are used throughout the world, not just japan. Most v-8 blown gas or injected nitro v-8 drag cars(dragster and funny car) use acl's as their bearing of choice. These are 2300-2500 horsepower engines. They seem to work fine there.
Whether a car runs 8's, 9's or 10's has very little to do with what bearing is used.
spin2win (8:16 AM 12/24/2003): hey first im not the idiot i think you are if you go back into the forum the post will not lie that everything i said was correct you should watch your language! how bearings are made i dont knoe. v8 are v8 whether if those make more or less power than us hondas do thats a different motor we are talking about hondas here not v8
