22RE performance and toughness

[Stefan]

It's a lighter engine which in turn leads to a better handling car...

Did you weigh the 2 engines? Any rough idea of the actual weight difference? I have heard that the 1G is lighter than the 2xR, but have never seen any numbers.

Out of intrestest, what car did you put it into?

[ViPeR_NiPPleX]

Umm, defiently better than 18R note that it has to be a 5m-Ge... and that mod is probably only relevant to Analog EFI, not the TCCS one, so check which one you are getting.

the 5m-e t/b will bolt up, but the ports for vacuum should be blanked off... and I assume that almost all 22re's have the analog electronics, even the corona's i've seen don't have tccs

coronas 86on have tccs

Excuse my ignoance but is analoge with the old style afm with flap in it and tccs new type with no flap.???

[Norbie]

Both types have a flapper-type airflow meter. The analog bit refers to the circuitry inside the ECU; later versions are digital.

Do you mean electronically compatible as well as physicallt? When I was looking at doing this years ago, I was told (by old celica club US folk) that it was only particular AFM...5MGE?... that has the afm with a similar signal to the analog 22RE, but higher flow. Other give an inverse signal IIRC, but I am a little hazy on this - it was years ago.

Im a 50 year old mechanic/engine builder,Old school chev ford mopar etc:Been building old old school race cars for 25 years.

I think im gunna have to learn a whole new alphabet.
Ive been out of the trade for a long time so im not up with efi at all,Its like being back at school again.
Give me a 4 barrell and V8 and im at home.

So i do appreciate all your help.Just takes a bit to get my mind around a totally different concept.
And a lack of understanding of the 4cyl hightech jargon,But i will get there.

there is no real diffrence dale! what i do on a 22r,4ag2j what ever, is pretty much all the same exept for push rods, which do have there advantages and disadvantages over buckets!
its all pretty straight forward.
The way to look at twincams etc is that they are setup the same as a race chev, they just have buckets and much lower spring seat pressures! besides that there the same.

I've always felt that modding a 22R is more like an working an oldschool engine than a modern Jap engine anyway - Tough, single cam, 8 valves, torquey, rough . Seems to respond to the same kind of work, too. Perhaps this is why they are popular in the US.

Hi,

They're popular in the US 'cos they never got the DOHC engines. Most of the 4cylinder Toyota engines they got were 20R and 22R. They got some 18RC engines, but the vast majority were the 20/22R series. So, they make do with what they got. I'm sure they would of loved to get the 18RG but it never happened.

I'm talking mainly about the Celicas they got over there - they had the 20/22R engine.

I realsie that, but that wasn't my point.

[Norbie]

They're popular in the US 'cos they never got the DOHC engines.

But we didn't get the DOHC engines either - so why aren't 22R's popular here?

I think the obsession with 22R's in the US has little to do with availability, but that's getting a bit off topic.

[Stefan]

Yay! Someone agrees with me! And it's Norbie!

coronas 86on have tccs

How do itell the difference,,,going to the wreckers tomorrow.

[bansheebuzz]

look at the dizzy, if it has no vac advance pod then its tccs
