|Propane||.080 over is 2.6 liters now and it's fine as long as the head is not rotted in any way. You also need a head gasket with the larger bore made into it.|

|NOODLES||I think rebuild kits start at 60 over anyways correct? So 80 would be only 2 times over. I wouldn't worry about it. But whatever you do, use a new crank. It seems the machined rebuilt ones do not last long.|

|Aisin||$700 for 4 pistons. I can buy a running driving Lexus LS400 for that much.|

|redneckguy0404||I just got my 20/22r back from machine work. 80 over with wiseco K509M94 pistons and should be around 10.6:1. I paid $728 for the pistons, machine shop price. I think summit has them for just over 500. being EFI the high compression may pose some issues for you so may look into propane. that's where im heading at least.|

|Mr Stubs||80 over needs a propane turbo..|
|05-24-2016 06:57 PM|
|84Toyotakrawler||Yea A 3.4 would outperform my 22re for sure. like Stubs said my pistons were expensive I think in the 500 range if i remember right. I have around 3000 in my motor. You can pick up a used 3.4 for under 1000 bucks. I like my motor a lot has great power and has been reliable but If i personally did it again i would swap to another motor maybe even a 3rz|

|gnob||Youre never going to out torque the 3.4 with a 22RE. (PERIOD).|

Pistons are going to be in the $600 range.
This is a very important question. Is your engine going to be carbed or EFI? And if it's EFI is it a stock or stand alone ignition?

Was aiming for 9.8:1 ... Or maybe a touch higher... hoping to go as high as 91 octane will allow.
I messaged LC and he said they can custom make pistons for whatever bore/comp I want, but he didnt answer me on the cost.
I need to find out which block i have first though... 5 years ago the engine took a crap and i swapped the block to one a friend had. No idea what it originally came from. Ill have to go look.
So 84krawler you reckon a 3.4 stock motor would outperform the 22re setup you have now?

|84Toyotakrawler||my motor is .80 over Has roughly 5000 miles on it driving to and from rubicon/fordyce (4 hours each way) always been good to me! If i had to do it over again with all the money it ended up costing me(forged pistons LC Head Arp studs cam, springs etc...) I would swap a 3.4 or something like that in.|

|iwannabemro||My crawler 22re short block is a kragen reman from 8 years. It .70 over still runs like a top.|

Worst case scenario you end up finding a thin spot and boring into he water jacket, a sleeve and rebore can fix that no problem and a competent shop should be able to do it for you no problem.
What ratio are you going for?
|05-22-2016 05:03 PM|
I know of one for sure and have looked into it as well.
I do know that you will need to pay attention to the head. We all know that old heads can be problematic due to electrolysis. Be prepared to buy a new head if yours is compromised. That big of a bore pushes tolerances to the max.

.080 over 22re
Has anyone done this? Was it reliable? I'm in need of a rebuild, and want a compression bump. The higher comp pistons can only be had in an .080 over bore.
