Engine Work at Home

Im putting together an engine build and was curious if anyone here does a lot of their own engine work. Im talking about either a rebuild or building up the engine for performance, etc.

Im not worried about tearing down an engine for cleaning and inspection/measurement because Im familiar enough with that now, but I have people telling me that honing cylinders at home is "easy" and the equipment can be rented even.

Im probably going to have to bore .020" over first as well and I definitely dont have the set up for that.

lol, you do not want to be honing your own engine if you have zero experience. There is a reason machinists charge $120 plus an hour and it's not just for equipment cost!

Ive done all my engine work minus honing. I'd rather pay someone to do it professionally for 20 bucks a cylinder than screw one up myself to spend 500 on a new block. If they screw it up, they pay for it

I would not do your machine work at home. I just built myself an engine and I did everything besides that.

Idk about multiple cylinders, but for dirt bikes honing is just to bring the cross hatching back so that the rings will seat properly. For cars I would assume it is the same, but car engines are way different and we know what assume did. I know my dad has honed out some of his old v8's and a 3 cylinder chevy sprint when I was a kid with the 3 puck honer and a drill. if you are boring it anyway, then you wont meed to hone it. They will do that then. Putting things together at home is good if you know what you are doing. It doesnt seem very hard from watching the power block on spike......lmao!! Yeah.....right.

Building an engine isn't something you can just dig your hands and start going. There is a lot of math involved into calculating what you want it to do for you. You will need to get certain tools that will run your bill up high, then trying to bore anything, it requires experience.

First off, you need to know what you want it to do. Then you will need to measure out CC's, bore, stroke, compression ratio, valve clearance, gasket thickness, proper valve buckets (lifters), valve spring dampening (measuring spring rate), valve diameter...etc...you get the idea now? That's just the engine itself without ECM calibration, yet alone going forced induction. There is a lot more, like intake runner length, intake plenum size, throttle body size...its engineering.
