Question 22REC and 22RE...differences?

I'm currently on the market for a rebuilt engine. A fellow wants to sell me a 22REC, is this different from a 22RE? I'd like to know before I fork over a $1000 for an engine and I can't use it...

Just typed a search in google and in another forum they said the C stands for being California emissions compliant.

"R= head design, Single overhead chain driven cam.

E= Electronic fuel injection

T= Turbo

C= California emissions compliant for that vintage

22= 22nd overall variant of that engine family. Engines in this family were in everything from forklifts to Celicas to who knows what else."

Does the new engine come along with the computer/harness? I believe they are different (due to the additional sensors and such). Here are two diagrams showing the differences:

22REC:


The following link has much more information on the different flavors:

Do you need the entire thing, or are you just getting a good long block?

I would worry about it as long as you have all your trucks original intake, wiring, and accessories you should be good to go as far as swapping in the long block.

Its just more smog shit. You wont need a new ECU to run it.

EC is for electronically controlled, I believe that's how it's worded in the 85 fsm I have. That 22REC won't have any aditional smog stuff. The early California emissions efi motors actually had less smog stuff than the federal motors, based on the emissions diagrams. All have egr's, all have a catalytic converter, all have evap setup so what more does a Ca. motor have, I don't believe anything. If it's above an 87 or maybe it's 88 then you start seeing more emission stuff in general.

When I shop Napa auto parts for example, they don't have parts for RE or REC, it's either 22REC(efi) or 22R(carbureted). No question wether it's a Ca truck or federal emissions model.

A -- Valvematic variable lift intake head
B --Twin SU-style side-draft carburetors (After 2000 indicates E85 Ethanol fuel )
C-- Carburated / California Emissions Controlled
D-- Twin Downdraft carburetors
E -- Electronic Fuel injection
F-- Economy narrow-angle valve DOHC
G-- Performance wide-angle valve DOHC
H-- High compression High pressure charged (example: 2L-THE)
I --Single-point fuel injection
J-- Autochoke (Early models) or unknown pollution control
L-- Transverse
M-- Philippines' market (meaning unknown)
N-- CNG fuel P LPG fuel
R-- Low Compression (For 87 and below octane fuel)
S-- Swirl intake (1980s)
SE-- D-4 Gasoline Direct Injection (1990s)
T-- Turbocharged
U-- With Catalytic converter Japan-spec emissions
V-- Common Rail Diesel Injection (D-4D)
X--Atkinson cycle (typically also indicates a Hybrid engine, as Toyota only uses the Atkinson cycle with hybrids)
Z-- Supercharged (For example, the 4A-GZE code means that it's an engine from the 4th generation of the A family, supercharged, electronically fuel injected, with performance cams.)Note: Toyota, in 1987, began assigning dual letter engine codes to some of the "engine family" categories in some engine lines, particularly six cylinder models. This can create potential confusion. E.g. 1MZ-FE - This is not a supercharged, narrow angle, fuel injected M-series engine, but a narrow angle, fuel injected MZ-series engine. Confusion is easiest to avoid when using the dash to separate between the engine series and its own characteristics: for instance, 1MZ-FE rather than 1M-ZFE.

Long blocks are "the same". I know because I put a RE into an REC (REC everything except longblock, ie intake, distributor, exhause, pies for cooling, starter, alt, etc)

What are you trying to say, you put an RE into an REC?

I just noticed post#3, from 2011, thats bullshit. I can't believe no one corrected him. That diagram that's supposed to be a "22rec" is a carbureted motor lol.
