If your machinist is meticulous there is a installation guide you can google it print it and give it to him ... then you should be ok .

Well I guess I'll start saving and do it right, but for now I'll just run some sr16 pistons with n1 cams. I've got a grudge match with a b20 vtec hatch, wanted to destroy him but just beating him will have to do lol

Doesn't work like that, a lot of people underestimate the sleeving process, and fail. Meticulous or not.

Yeah, i had an awesome machinist that did worked for Napas machine shop and has been there since the 70's. He said yeah no problem, gave him the instructions and all and he finished the job and so on and looked good. However he didnt use a torque plate during the final bore and hone and then did the final decking and we got the 2.2L VE together and it ran alright but as soon as breakin was done and first WOT pull, it started overheating and pressurizing the cooling system. I knew right away what was up.

Pulled the head and all the sleeves had dropped a good fingernail thickness or more down blowing the gasket.

Luckily being it was done through Napa, they warrantied the work and paid for the cost of the block, the headgasket, the sleeves, the labor, and an additional $500 in pain and suffering money. So they came through on their end at least.

The machinist told me he was used to doing the V8 sleeves and has torque plates for them but he started getting worried during that final bore/hone/deck process if the sleeves had lifted up. He was like well thats the last time I take a job like that. But everything else I always used him for my regular cleaning, overbores on stock sleeves, decking, head resurface, and you name it and never had any problems and still would use him over anyone else in the area. Ive given him a lot of business with mine and customer vehicles I was working on. Top notch in everything else ive given him. No worries.


Im just saying sleeving these blocks is a hassle and if you dont have the right stuff, I can gurantee you it wont work and last.

Had the guy from Napa had a torque plate, no doubt it would have lasted and been performed 100%. Thats how good the guy is.

Lol wow, I work for Napa and my machinist works at my store. Same story he's been there since the store was built and does real good work, he does all my stuff for free if not real cheap, usually just the hazardous waste bill. He sleeved my friends 2.1 gsr and another friends 4g63, the gsr is on spray and the 4g is running 25psi both running good to this day. But if you say an Sr is a whole other ball park I'll take your word for it and get it done right

Its really not a matter of an SR block being that different. Over a B series block yes. you are talking about open deck that you can press the old sleeves out then machine while on the SR you have to bore the cylinders open until they reach the desired opening to press the sleeves in. Alot more work involved, alot more wear on the cutters.

Main thing is having a torque plate to keep the sleeves pressed down during bore/hone process then end with the decking. That way you are 100% certain the sleeves didnt lift during that process. Again i would seriously go with a place that does the sleeving and work with a torque plate. No place that does just one job is gonna front the $500 for a torque plate to just do one job. Go with a place that does them on a regular basis and you will not have anything to worry about

Again i prefer mazworx, top notch, sleeved and stepped block and not a single problem so far. Most people on here with sleeved blocks have mazworx blocks and not a single issue. Couple others have used other reputable places like AEBS and so on.

right...structurally (design characteristics, etc.) and dimensionally (tolerances, etc.) blocks are different....so you cant treat them all as one...hence my previous post lol
