If I bored and sleeve a block over to 84mm and use a OEM crank can I use std size acl bearings and thrust washers?Also can I run the OEM oil squirters with 84mm pistons and sleeves or should I buy the GE plugs?
Thanks in advance-Chris
PS don't go too hard on me its my first build....

 

Squirters clear with the 87mm crank but usually won't clear the piston skirt with the 89mm crank. I hinknit depends on the piston.
If the journal's are all still stock, std acl berimgs should work but should definitely be checked just to be 100% sure clearances are where they should be.

 

Crank is stock 87mm gsr, pistons are 84mm Nippon racing pistons . so was just wondering about the squirters....

 

will fit. hx bearings are better then std h bearings

 

99% sure youll be fine.
Just check it out on assembly. Youll probably need a small mirror to get a good view.
The HX bearings will give you a little extra clearance (.001") if you need/want it. As with any engine build, bearing measurements are critical.
I had to use a mixture of HX and STD bearings to reach my target clearance FYI.

 

Hx=acl bearings? Sorry I'm a little wet behind the ears. The street acl bearings are standard size.

 

ACL bearings that end with an A are typical oem replacements. ACL bearings that end in H are the race series bearings. ACL bearings that end in HX are race series bearings that are 0.0005" thinner, which equals 0.001" extra clearance when both sides have HX shells installed.

you can mix and match H and HX shells to achieve proper clearances.

shell = one single bearing.

 

If a shop was going to assemble the block would it be ok to just include the one set of acl race bearings or would it be advised to purchase another set for a good clearance?

 

you can order just the one set, then they'll spec the clearances with those bearings and advise if others are needed for proper clearances

 

Thanks man...I already ordered the bearings previously and I'm just really on the edge of my set hoping my build will go as planned. Sorry for the all the tedious questions.

 

At least your asking questions now instead of asking why your engine spins a bearing in 6 months. Good luck on the build.
Thanks for the clarification Motoxxxman.

 

True....unfortunately I've still got a long ways to go.

 

x2. always better to ask and learn beforehand than to find out the hard way. a million questions is better than no questions.
and you're welcome

 

we all started somewhere.

 

Really appreciate the endearing words and info guys!
