Well to my dismay my tired, and torqueless B16A w/ CTR cams, pistons, and crower valvetran is making some pretty bad noise. It sounds like a rod bearing possibly. So is appears it is time to build the LS motor I have sitting in the garage. Project daily driven and NA LS/VTEC, is born.

I will still use my same top end it still seems good. I do want to tear it down and give it a good looking over and replace the valve seals though.

The bottom end I was planning on JE 84mm pistons 10.5:1, stock rods with ARP bolts, stock sleaves, Z10 block girdle, replacing all bearings with OEM Honda.

I will probally only rev to 9000rpm at the track occasionally. Will this setup be good and reliable? Is anything excessive? Should I add GE sleaves and eagle rods, or is that overkill? I just want a reliable fun motor, that runs fine on pump gas.

Thanks in advance.

 

if you plan on using the stock sleeves, the max bore i would suggest is 82mm. rsmachines sells them. if you go 84mm youll have to sleeve the block

only sleeve it if you actually want to put 84mm pistons in there. otherwise your going 81.5

sleeving will add another 800 or so onto your project ontop of needing forged pistons/aftermarket rods (about 700 or more). you will be fine with b16a pistons .25 over and you will be about 1500 or so less expensive.

 

Ok so then I'll go ahead and sleave it.

Also is a ITR oil pump necessary?

 

any other tips???

 

a vtec oil pump is a good thing.

search.

 

If you want to go 84 mm sleeve the block, get the forged internals, and get all vtec oil/water pumps. If its all-motor then maybe you might want to get some higher compression pistons too.

I really just want to run pump gas and have a run reliable ride. I am also building a turbo motor for my other car. It will be the beastly one. This setup is just to be simple and reliable.

 

u can sleeve it. thats never bad but the way ur talkin i wouldnt . if you would 84 mm just get a b20. the only thing tah seperates a ls from a cr is the ls's 81 mm to the b20's 84 mm. other than that they are identicle. my b20 vtec pulls on sohc vtec w 7 psi in ef-eg hatches- 240 sx w sr20det psi ?

 

that compression is pretty low, i would go atlest 11 or 12:1 you can very safely use that with pump gas.

Word. Depending on where you live if you get 93 octane you can safely run 12:1 with no problems.

Not to question you but with my B16 I had to run 50/50 110/93 or I had pinging

if the motor had problems itll be alot more prone to pinging.

 

The only thing I could think of is the Mugen program ECU has more advance timming maps and that is what I was using. It only pinged when real hot out. Would the ecu cause that? Everything else was pretty much new, and I also piggybacked in a VAFC to control the fuel.
