All right,
There are always reference in this forum about Toyota engines. And they always refer them by thier engine names, ( i.e 7MGE or 5MGE ). Where can I find what all these engine numbers mean, and which cars they are in?
Since I don't know what engine is what, it is hard for me to know what stuff I can use on my truck.

Thanks
Kent

Vrooooom

this isn't thorough, but you'll get a rough idea.

5mge .... used in the toyota cressida, maybe second generation supra. inline 6 cylinder.

7mge ... used in the 3rd generation supra. naturally aspirated. about 200 horsepower. inline 6 cylinder

7mgte ... used in the 3rd generation supra. turbocharged. ~220 horsepower, but very easy to increase horsepower to around 300 or 400 horsepower. inline 6 cylinder.

22r ... toyota 4 cylinder. used in the earliest pickups up to mid 1980's (or 90's ?). carbeurated. reliable workhorse.

22re ... electronic fuel injection version of the 22r

3vze .... v6 used in pickups from 1988 to 1995. also in 4runners.

5vze ... v6 used in the 4runner and tacoma from 1996. also t100.

2uzfe ... v8 used in tundra

is the 5vze the 3.4 V6?

CLin9383

yes

Los Gatos?

7mgte are 1st gen supra. The 3rd gen's are 2JZ... They make 330 hp stock.

Los Gatos?

1st gen supra - 1979(??) to 1982 (really that's a Celica Supra)
2nd gen supra - '82 (or close) to '86.5
3rd gen supra '86.5 - 92 7MGTE first used
4th gen supra - 92-98


To clear that up just a little bit.....

Not quite,
22re was standard for 4runners

22re was an option for 4x4's 85-87, standard in 88

22re was an option for 4x2's 85-91, standard in 92

Todd

Los Gatos?

Wow I didn't realize the 22R was in later trucks...


On a side note, is the 22R in my '85 the first year of the NEW block style, IE the one that you can't put a 20R head on, or the last year of the OLD style, that you can put a 20R head on?

Todd E

Yup, the "lazer" block was used from 85-95.
It has a shorter block and a shorter head than the origional design (81-84).
Another thing,
The celica's and corona (?) that used the 22r's and re's are the same as well.
I have an 85 celica block in my truck now, just needed to change the oil pan and oil pickup tube for it to fit.
Oh, there is a difference in oil pans and oil pickup tubes between the 2wd and 4wd motors as well. It's all about clearance of the frame supports.
And another thing
Toyota introduced the 22re in 83 (I think) in the celica, so it's possible to have the early style block and fuel injection at the same time.

Los Gatos?

can you have an early style block, 20R head, and fuel injection at the same time?

Todd E

Not sure about that.
The 20R uses round intake ports and the 22r uses square shaped, including the early 22r's, if I remember correctly.
I'm sure it can be done though. The mounting bolts are in the same location.
Of course, most of the time the 20r/22r combo is used with dual carbs, yada yada yada for the higher HP gains that aren't really obtainable with the EFI system, or should I say easily obtainable
It would make an interesting combo if the airflow is smooth.

Los Gatos?

I'm certain I read somewhere that you can NOT put an early 22R or 20R head on a late 22R block

Todd E

Actually, you can, but you get into timing chain legnth (I think there's a BMW or Porche chain that works for it though) and compression issues (the early 22r and the 20r use domed pistions, the late block uses flat top pistons).
But you are right, the early 22r block and the 20r is a direct swap.
You should be able to bolt on the 83 celica EFI setup to the early 22r block as well as the 20R head, but I don't know for sure.

Los Gatos?

Is it a piston HEIGHT problem, or a "too much compresson" problem?

Todd E

When you put the 20r head on a late 22r block, you are running less compression - flat top pistions in place of domed, and the 20r has a larger combustion area, the other way around (late head on an early block) and you have pistions hitting the head in a bad way.
There's a website that explains the differences (with pictures) between the 20r, 22r, 22re, and 22rte. I'll have to try to find it again (didn't bookmark it for some reason )

you cant put a older style 20r or 22r head on a newer 22r block. when you put the pistons to top dead center so timing will be rite when you install the head. the domed part of the pistons will hit the head. the head will not even sit flat on the block there will be a 1/4 inch gap. the cumbstion chamber is totally different and that ruins the idea. i know from expirence about the 2wd and 4x4 oil pans being different. my 81 4x4 i use for a daily driver had a 2wd engine in it and they did not switch the pan and the front diff smashed the pan. was like that when i bought it. it even had a 3 inch lift. where the pan drops down is in the front of the engine on a 2wd and 4x4,s are in the back.
