Rebuilding 6bolt 4g63 Tips/Advice

[DsMWookie]

Welp my motor started knocking/ticking the other day and I've gotten tired of putting work into a worn motor (160K). So I am pulling the motor to tear it down and get it ready to take to the machine shop. I already ordered .20mm over Weisco pistons and Eagle rods. I am gonna run ARP head bolts and pretty sure I am going to buy a bearing set from Mitsubishi. The head right now is stock other than HKS 264's in it. I am probably going to upgrade the valves to SS. I am looking into getting the head ported and polished mildly because funds are a little tight and I wasn't expecting this.



1) question what is the benefit of nitrite valves?
2)Is it bad to have the crank turned if the rod bearing has scared the crank?
3)Oil pump was working fine should I check the tolerances by the manual and re-use?
4)Does it matter if I'm not using the same block from the car being that Im having the block deck and head resurfaced?
5) Should i keep the factory oil squirters? Someone just mentioned this and I have never heard of getting rid of them for 6bolts.
6) The factory springs and retainers will be fine for big power as long as im not revving it past 7.5k correct?


Please let me know of any advice pointers you have. I am not trying to be a cheap ass in the build but I am limited on funds since I just bought a new clutch and turbo right before this happened.

1) Nitrat valves I would not worry about since your on a budget.
2) I have and others have turned the mits crank. The thing is that the crank has a special hardining material on it to help it last. If you turn the crank and do not have it rehardened it will not last but maybe 50-60k. If nothing has spun. measure the crank and polish it.
3)If you have 160 on your motor I would recomend buying a new front cover and oil pump assembly.
4) It doesn't matter what block you use, but you shouldn't need to have the block decked. Just have the head resurfaced.
5) Keep the squirters. They are there to oil the cylinder, piston and rod pin. If you remove them they could build to much heat.
6) Yes they will work. but if you have 264's I would go ahead and get crower springs and retainers or what ever brand you prefer.
