I got my block assym. back and my bore is 85mm however I already bought a cometic 84mm bore gasket. I dont think this is a problem but looking for advise and opinions.
Well, then my advise like the other have said would be to try to return it and get a 56mm one. Worst case, you have to try and sell the one you have and just buy a new 86mm gasket.cnewingham said:yup, I am sure. I am also running ross pistons.
You cant. Well, you could put it out as far as you want until it hits the next cylinder, but he will grenade the engine. The factory only sells .5mm over for a reason. 1mm can be done with precautions.I had no idea you could bore a 7m that much.
Basically... if you want to be completely precise its .254.gixxer750 said:.25 mm ~ .010?
Automotive wise, grenade doesnt mean to explode like a handgrenade. There isnt enough cylinder pressure to break apart the cast iron block. Grenade is just a term for ruining the engine past the point of being able to rebuild. And yes, it wont last long.So you think I am going to grenade the engine?
u sure its that big of an overbore?_? looks smaller to me.cnewingham said:So you think I am going to grenade the engine? I dont think so. I bought the car with rodknock (owners error) and it had been running great prior to him losing a line to the oil cooler. It was far from stock. The head is ported and polished and was running HKS cams, HKS long runner manifold with a 60 trim t04, the same forged pistons that are in there know. Etc.. as the list goes on. When I tore the block down the cylinder walls were in awesome condition so the block appeared to hold up pretty well.

Yeah o.k. 200 engines and you know all. Who cares how many you have built. I ran an engine and trans repair shop and I knew mechanics that have built motors for 20 years and still didnt know what the hell they were doing. Not trying to start crap but I asked about the hg, not if you think my motor was going to last or not because it has already proven it will last.But what do I know, I have only had to do less than 200 Toyota engines, so I dont have any experience/education/knowledge on the subject.
