Ok im trying to buy a short block off this website so i can have an extra engine to work on and still be able to drive my car. so on the shipping info they ask piston size needed, and bearing size needed. the piston size i just want to know the biggest size i can go before having to bore and i have no clue about wat the bearing sizes are so any help there world be appreciated. o ya its a 96 1mzfe

ask for std. size for ur car...they should already kno wut it is...u cant just go a bigger or smaller size or u would have too big of bearings and rings or too small of both...including pistons. i believe stock on 3vz-fe is 87mm bore, 1mz SHOULD be the same but im not positive. Dont forget if u have to buy internals separately there are a number of different sized rod bearings for these engines...the 3vz-fe has 3 different sizes alone...i dunno bout 1mz

i highlyhighlyhighlyhighlyhighlyhighlyhighlyhighlyhi ghly reccomend going to the dealership for rod bearings at the least, wut ever u do DO NOT buy them from a regular parts store ie autozone, advanced autoparts, or other stores even like IPT, especially IPT. none of them have any clue wut they are talkin about or selling u. I kno this from experience. I did a good explanation on how and why to buy bearings posted on shiftgate's forum but that been down for 1500000000000000000000000 years now

The bearing sizes are typically located onthe main and rod caps. I do nto rememebr waht the actuall marking is but that is where you would find it. wiat a minute though if you are buying a short block they should already have all the bearings and stuff inthem. A short block would be just the block of the engien with the bearing, rods, pistons, etc. All the internals anyway. Are you sure you arent jsut getting a stripped block.

Glad I wasnt the only one. I know it has been a while since I turned wrenches but didnt think things had changed that much.

2x check wut exactly ur buyin ther wicked, make sure its a full engine, not JUST the block

WickedLexus96 · 07-05-2005, 05:13 PM

it is basically the full engine. its off of the website importperformanceparts.net and u go to toyota and then u just go to engines in the long list of stuff they have for the toyota then u click on what year camry.

Complete Engine: short block assembled with complete cylinder head, all timing components and oil pump; no oil pan, valve covers, or manifolds are included

Short Block: machined and assembled with over-sized pistons, rings, matching crank kit, connecting rods and camshaft (if applicable)

Complete Cylinder Head: New or non-welded remanufactured head assembled with camshaft, lifters or rockers and rocker shafts (if applicable)

Cylinder Head: New or non-welded remanufactured head assembled with valves, guides, springs, retainers, keepers ad valve stem seals

those are the kits they have u can choose between any of them. but they all have different prices. but should i just go with the whole entire engine or just the engine block. if u can refer me to another link please do cause im not sure if i can trust these people being an internet site and all.

Get the whole engine. You can't tell them bearing size untill you remove the crank from your block. Or just get the block and deal with the bear later. In fact it maybe cheaper just get a used engine from someone just did a swap.

I jsut want to make sure I am understanding you correctly. You are buying an engine jsut to have it right. If that is the case I would reccomend buying a used one tht has not been blown up or anything like taht. I am guessing that you want to start fresh and start building your own performance engine or something along those lines. The only reason I am saying this is because you are wanting to have an extra engine so you can keep driving your car. It doesnt really make sense to go out and buy a remanufactured engine jsut so you can tear it down and start rebuilding it the way you want to. It would make more sense economically to buy used then start the building process. SInce you are going to pay upwards of 1500-2000 US dollars for a reman, when I am sure you can buy one used for a lot less. It would be different if you were jsut wanting a replacement engine if yours was shot and wasnt worth rebuilding or didnt have the time to have it down while rebuilding. I hope this makes sense. But anyway another good engine company is ATK engines. We used to use them at the dealership I worked at and they were great they give good warranties and also they are highly recmmended in these forums. I have found two different links for them but one looks like a distributor and the other is the main company webpage. Try www.atkengines.com or www.atk-engines.com
