this one goes out to anybody who has done an engine rebuild on their max. i am mos def gonna do a rebuild on my 90 gxe and i was looking for some insight and direction on where to get parts and where to go with the rebuild. i have heard to just buy a new motor because the ve isnt worth rebuilding, but i dont have the money for that and this rebuild is for school anyway so i need to rebuild. was looking to increase power a little bit and this is what i had in mind:

port and polish the heads
valve job (can vg30e engine valves be interfaced or do they have to be replaced??)
i was thinkin of boring it out a tad too but im not sure of that but what could i do about getting pistons and whatnot

the only issue with money is expensive parts, like if i were to get new pistons and valves and whatnot. other than that im just lookin for some insight and direction from people who have done it, had it done or know somebody who has.

thanks
Anthony

 

I sell ALL the parts necessary for a rebuild. Heck I think I can even get motors complete (not used)

 

FIRST you need a factory service manual, from nissan not a Chiltons. Yes its expensive (IIRC ~$120 new), but its the ONLY way you will accomplish this.

Secondly, if you could explain what is wrong with the engine because there are many parts that you may not need to replace, and a semi-complete rebuild could easily run you over $1500 in parts alone
You can get pistons and rings from Nissan (~$400), which are avalible in oversizes 10 over and 20 over. Im sure Internetautoguy can get them cheaper, but at such small oversizes you wont see any performance gain. Only bore the block if the walls arent true. Just get new rod and journal bearings ($175) and rod caps ($50) for the bottom end.

Assuming you valves are in good shape, you can regrind them yes. Your lifters will probably need to be replaced however and arent cheap ($300)

Port and polish may provide you some gains if you are experienced in this area, but I'm not so I cant really help you.

There are many many little parts you will need like gaskets and head bolts, etc that will add up quickly.

 

thanks for the help.............keep it comin

 

can you get the single overhead for an 89 max? and if so, how much?

 

I agree...why new rod caps? they should be fine unless there was some catastrophic failure. if anything new mains and rod bearings

 

yes I can get it $1500 plus whatever shipping may be.
