Nuts, Bolts and other stuff... Rebuild!

So as some of you know i'm rebuilding my Engine, doing a total refresh from top to bottom. With the Engine being 20yrs+ old now, most if not all nuts, bolts are all rusty, falling apart, look terrible.

My question is this, where can i get new ones other than Toyota, or does it need to be ordered Specifically to like say the Oil Pump nuts and bolts i pulled off? Or can we use anything with the same pitch, length, etc?

Thanks

Put them all in a box, find a local reputable re-finishers and have them all acid stripped, zinc & clear coated. They will all look shiny new and it's considerably cheaper than chrome.

Also you get to retain all original toyota bolts... Which I'm a fan of!

You don't want to use just any old bolt, most of the Toyota bolts have specific tensile strengths dependant where and what they do. I have replaced some on my engine rebuild with new ones from Toyota.

cheers guys, yeah i'll get them all stripped and cleaned then, and try use most of them, if ones are totally buggered, i'll buy some more

You need to be a bit careful, but many bolts can be replaced with either cap heads or 8 grade hex heads. Careful means ensuring they aren't "special" bolts, or requiring of a specific grip length. I can only suggest you find a copy of Carroll Smith's great book "Nuts, bolts, fasteners and plumbing handbook". Probably the most readable and comprehensive book on why you need what.

But off the top of my head, the bolts in a 2JZ you MUST replace with OE or better are:

Head bolts, rod bolts, main cap bolts, crank pulley bolt, flywheel bolts. Quality high tensile bolts with the right thread and grip length can be used as replacements elsewhere, as none are particularly highly loaded in either tension or shear.

i've bagged and tagged pretty much everything i've taken off, so if need be i can reuse or buy selected new ones from Mr Oyota cheers chris

The fun comes at the end of your rebuild, when there's a lonely bolt, and a funny "thingie" left in your bags, and you ain't no idea where they should have gone We call it lightening things in the trade....

In time you get a spare engine.

no doubt they'll be a few wtfdtbg bits ad bobs left, good thing is i've got Hodgy boy helping me.

For all the key bolts Chris mentioned above I used Toyota except for ARP on the head. Outside of that, I either reused the originals if they weren't fubar'd and were going to be out of sight or if they were going to be seen, I ordered stuff from these guys:

Good quick service and you can order individual pieces in either chrome or polished SS for most stuff.

Just *NEVER* use chromed bolts for anything critical, they can suffer hydrogen embrittlement in the chroming process.

I call them corner bolts personally..!!
