Darton makes three different sleeves for EJ, so having various finished cylinder wall thicknesses can already be done.

1. dropped sleeves 2. cooling issues at track #1 has seem to be debunked with proper maching, #2 i would assume because the sleeve is much bigger and reduces the coolant passages a bit too plus is thicker |

dropped sleeves are from poor work and/or from overheating the block.
what cooling issues are you talking about?...you haven't said anything other than 'cooling issues'. The sleeve doesn't block coolant passages. |

maybe sleeved blocks are pushed harder, thus more heat, thus more chance of overheating.

I actually meant to state that as a point but forgot
after all, they are sleeved for a reason. more power = more heat |

^ does this really work for high boost apps? I'm building my block turning it into a 2.7 but worried about the cylinders cracking on me since il be boring them out to 100mm.
The power I expect from this build is around 420whp to 460. Another thing Is that I'd sleeve it but the heat transfer isn't that great. Do they make aluminum sleeves rather then iron? |

Why do people say iron sleeve blocks are not good for daily driving?

yes thats good for high boost its alot thicker then the standard wall was and this specific one will be running 25psi+ on a dom4 Xt-r All day in S# mode. Just something to keep in mind is when you get that done, make sure to deck your heads. so w/e that equates to which will be more then your requirements.

if that one is the only reason... there should not be a reason for not getting the motor sleeved other than cost.
What material pistons and size would some one choose to run a sleeve motor reliably, keeping longevity as the main focus? links? There is EVOs on the stock pistons running about 400whp for 200K miles |

you can bore that specific sleeve from 99.5 to 102mm. so you have some gap if you blow somethign up. I like it cause it gives me a brand new start and i can setup the PW clearance perfect every time. I was sick of worrying about the sleeves cracking, pw clearances off cause the block was so worn. It personally hurts when i spend hours balancing everything to .1 gram doing clearances on all the bearings, then there is a soft spot on a cylinder wall and I have to start all over.

well keep in mind that most of the failures you see here are rod bearing failures, which can be from numerous slings.
Bad oil (loose term), dirty build, poor clearances, out-right abuse... At 50k, I'd go through an EJ that gets pushed simply to inspect, do rings and bearings. |

Not needed. Think about it. How much oil is coating your internals while your motor is running? Well its not even to within .1 gram I can tell you that.
About pinning, Ill be pinning the sleeves on one of the ej205 block I have lying around sometime in the next week. Ill post pics as soon as its done. |

^^Micah that is not a step sleeve,that is the first option sleeve in dartons catalog.To go 102mm you have to purchase the big t sleeve from darton and then have a good shop like MPS send it out to benson to have it done.

To your ? juan,no it may or may not last longer but the reason for sleeving is to run more boost which = more power,more heat and more cylinder pressure.So if your goal is huge power sleeving, if done right, will theoretically allow the sleeved motor to have a better chance at a longer life granted all the other systems(oiling) are up to the task.I hope this helps juan.

I was asking as it looks like a run of the mill industrial/cast iron block straight sleeve. Even smaller Darton sleeves are still stepped. |
