GSR block, b16 head, moderate boost. should I sleeve it?

I'm getting a GSR block and the cylinder walls have a little rust on them, and I think one maybe scared, but I'm not sure. I can get a killer deal on some brand new darton sleeves for a GSR. I want to be able to push 18-20 pounds of boost when I go to the track, but normal driving I probably wouldn't go over 12. I did a search and didn't find much info on sleeved blocks, atleast nothing that helped me. I just want to know some pros and cons to using sleeves. I'm going to use aftermarket pistons and rods, so it would make sense to change the sleeves. i want to know peoples experience with them.

I have a RS Machine sleeved B18A block and it works fine. In my old setup, with 19psi of boost I cracked the #3 cylinder walls after a few hard runs. The only "con" about an iron-sleeved block is that it will get hotter than the OEM aluminum block. In my case, I will be needing to get a bigger aluminum radiator and keep my eyes on the water temp. If you want to boost +12psi, I would suggest getting sleeves. Just make sure whoever is installing them is a reputable shop/person. You don't want your sleeves to leak. Oil + coolant = caramel <---- trust me on this one.

For me, Id draw the sleeved line at around 350whp. Some may find that conservative.

Im pretty sure he meant anything over 350 he thinks you should get sleeves. You can take stock sleeves up to 500 whp pretty damn reliably if you have a really good tune. You got a shitty tune, your gonna blow a sleeved block anyways. I believe it was boosted hybrid on here that is pushing over 400+ whp on stock sleeves with ease.

You can have the best tuner in the world tune your setup but if you have a weakened motor with "abused" stock aluminum sleeves....any excessive amount of boost will crack them.
