I’m rebuilding a LS short block that has high mileage; the rebuild is for a DRAG III set up booting no more than 12psi. Is it a good idea to get after market pistons or just get a new set of OEM pistons from the dealer? I will be staying with 9:2 CR. I have eagle rods al ready. I don’t know much about relsleaving, can some one give me some info or tell me where can get some info and pics of a resleaved block? Is there any site I can check out? I’m trying to learn as much as possible about building a motor for FI.

I have tried doing a search but the search on this board suck and the guys in the FI forum is no help

I would get some aftermarkets if you want to go to 12 psi.

Don't get JE though I have heard that they don't like Forced air.

 

What brand do you suggest? Can you give me some infor about resleaving?

 

I would suggest the Wiseco line, even their line sold by Endyn.
With that little of boost, I would think resleeving would be a waste...

So all would need to do is upgrade the pistons and rods and that's it.
Any suggestions welcomed.

 

Since you already have aftermarket rods you should get forged pistons.
Otherwise you would have to modify the stock pistons to use the rods.
JE and Wiseco are both good brands.

Agreed.... aftermarket pistons have a higher melting point and should withstand heat that may be caused during tuning & racing, etc. Just about any of the aftermarket pistons will be sufficient, just be sure to properly assemble everything.

 

Resleeving is basically removing your exsisting ones and putting in stronger ones.
I lost all my links for that......godzilla sleeves ?????

N-E-Way, you sleeves will be fine just look into other pistons here is a site that some people have bought pistons from

What’s the stock bore on a b18B

 

81mm

 

The b18b that i have has about 109k's on it you still think it will be ok without not to resleeve it?

 

You may need to bore and hone the block to take a 81.5mm piston depending on the condition of your cylinder walls. You would have to check the cylinder wall width and also check for a taper in there. I would just bore and hone it anyhow... its not that expensive. About 70 bucks or so.

 

if you only plan to run 12psi then stock sleeves are fine
