I found an AQ131c locally. Waiting for the price. If it's under $200 I'll probably take it. Sleeves are like $50 CAD each + machining. Just machining the AQ block would be cheaper.

Going rate for a pulled rear thrust b230 is $350-500 round these parts

it is more like 96,3 bore with 96,22 pistons.. and that gives the fit during operatings temps but causes pistonslap when cold..

I wonder how much boost those will take with the liners? Or is it more of a core shift that blows them up? It would be neat to sleeve my spare b21ft to be solid for like 600hp lol

You sleeve happy redblockers remember when Nathan had that bad assed turbo 16v motor? That the one sleeve he had put in it went boom? Remember that? How did he fix that? 2JZ..

What's a sleeve? One more thing to kool aid..

Yep, there isn't much of a performance advantage to sleeves at all. They exist to keep your block useable when the bores are way too hogged out to reuse and you can't find another engine.

There are regular sleeves and performance sleeves. I think that a 1/8 thick sleeve can take some abuse. A Darton sleeved Whiteblock T6 will take over 1000 hp.

How much HP was Nathan making with his 16v when it went kaboom? I would say a lot.

it wasn't making all that much. I think it'd been punched back out too big or something. that was a long time ago, and trying to draw life lessons from a sample size of 1 isn't always a great idea.

sleeving works, plenty of high hp engines get sleeved.

Motor made this on the dyno @ 20.5 PSI on the wastegate:



Than it did 3 little drift runs, no abuse since it was its for time out:



Then this happened:



Car owner (John Knox) thought headgasket failure again but nope...





Cylinder #4 bore cracked...

Knox will maybe have the block sleeved and the head oringed.

I'm probably going to get a couple sleeved back stock for various purposes, it's easier than trying to dig up replacement engines anymore, and having known quantities would be nice.

A 92mm bore would be a very nice thing to have indeed.

I doubt I'll go that small. I have appearances to maintain and such.

Knox will probably want to be able to keep his 96.5mm Traum pistons since they are still in a good shape.

Is sleeving the block and having it drilled to 96.5mm a viable solution? He's not going to run crazy boost levels and will probably settle for a reliable 20 psi tune that should put out around 400 whp.
