Shit idk what I was thinking about last night
Only thing I did to the oil pump was put new seals in it.

About to do a rebuild on my g13bb, I got a kit from america with bearings, rings, gaskets etc but forgot the pistons lol. Just wondering what is a good brand piston and where can I get them from and for how much? Also would like to look into rod prices as well. |

Any good auto parts shop should be able to supply a set of oversize pistons from ACL. Why do you want new rods? |

Good brand of pistons? Wiseco There is so much to know about materials and shapes of the pistons before you decide. Also you need to figure out if you are going to go and overbore, since you are already doing the rebuild. If you won't go over than stick with OEM quality pistons, that are the same size, which would set you back about $80/each. There is a company in Sydney at Wetherill Park who trades via EBAY. They are well priced. Just a query & a statement. I wanted to do a performance rebuild on my engine (a G16B) and realised that even a basic build would be quite expensive. So I opted for an engine conversion, with a bigger faster, newer engine. You will be surprised of how little you would save by rebuilding your own engine. |

I haven't priced it up yet but when I was quoted something like $1700 for a COMPLETE rebuild (thats new waterpump as well e.t.c) surely just doing a hone and new pistons+rings+bearings should be way cheaper? |

this is what i have worked out money wise so far for g16b rebuild.Bore and Hone - $138 Cut Seats - $173 Reface Valves- $127 Would be cheaper to do a full Recondition on the Cylinder Head- $313 I have added a detailed description of the reconditon procedure so you know what is involved. RECONDITION HEAD PROCEDURE Dismantle head, clean and inspect all parts for wear and/or damage. Check head for hardness and straightness. Inspect all valves and guides for wear and/or damage. Check all springs for correct seat pressure. Hot tank head and components, Bead Blast Head, Face all valves and cut all valve seats. Surface head face, assemble head, vacuum test all valves and wrap.rebuild kit around $400 inc.water/oil pump delivered.put together myself around $900..not too bad i thought considering it will be like new, |

Just did a rebuild on a g16a I did every thing asides the re bore and recon head. Only thing I didnt replace was, Conrods and water pump Cost = $1000-$1200 |

No didn't get crank reground, I think I should of Replace big nd main bearings Doesn't have oil pump I don't think Has oil pickup though. |

So even doing the lot yourself it still comes out to a $1000? That's bloody crazy. I was just going to go with new pistons + rings + bearings (and a bore if it needed it) The head was apparently rebuilt a month or two before I got it. |

i should find them |

WOW that is cheap as chips. I was quoted for a g16b rebuild. $900 Bore to 1.7L and Hone, inspect bearing replace if required. Supply new standard pistons. You need them since you are boring 0.40 of inch Full recon of the head, port, Cut Seats, 3 angle valve job 1mm over std. $900 That was me taking off head and block and delivering it to the machinist. Cams would have been untouched, Crank not knife edged. Think there we discussed decking and machining for a better compression. Hot tank head and components, Bead Blast Head, was included in pricing. I was going to re-assemble in and put in car. I freaked out. We did not even start talking forged pistons. My engined is okay as it is, but I was after more power/torque, but the gain/dollar was little, hence the reason I am pricing engine conversions at mates rates. gusbus wrote: this is what i have worked out money wise so far for g16b rebuild.Bore and Hone - $138

I got mine bored out to 40 thou You probs get no were near 1.7l 60 thou is the most u can go I think before u get weak bores I also got head and block shaved All ready been shaved before I got it shaved more( lots of compression) If I can remember it roughly cost me around the $400 mark to get head fully recon(every thing replace) plus sand blasted bore out to 40 thou Shaved And some seals fitted(oil pump, crank and cam) $550 for parts Vrs gasket kit New exhaust and intake valves 40 thou piston and rings to match Standard main nd big bearings Timing belt There's more bits but can't think of the top of my head |

you are right. It wasn't 1.7 but it was closer to 1.7 than to 1.6 I also think that the original pistons I wanted was what would have piven me the extra CC's. Not sure about the technicalities but it had something to do with the piston dish, or maybe that was to do with compression. Realistically it isn't very economical to rebuild if you aren't doing most of the work your self. Sometimes wish i was machinist. zooky08 wrote: I got mine bored out to 40 thou
