22RE performance and toughness

[dale30]

I got the message from my 18R thread that im a looney for not running anRG,BUT i cant have one at the moment unless someone wants to sponsor us with a free head.

So One of my sponsors have offered me a complete recently rcoed 22RE from an RT142

Anyone know what they go like and what they will rev to without detonating.
Any info at all would be helpfull to make a decision.
I Will lighten flywheel,extractors and cam.
Maybe chiptorque can touch up ecu.?

A Hilux motor feels like, well, a Hilux motor! They're certainly not a big revver, but feel like a grunty-pig 4 pot (which they are.) Changing flywheel, cam, and generally freeing up the breathing will definately help, but you'll never make big numbers with one simply because you won't have big revs. As far as the 'ECU' is concerned, it's very old school and there isn't really a lot that can be changed - you'd probably just stick to messing with the spring tension in the airflow meter and rotating the dizzy a bit.

With atidy up do you think it will perform much better than an 18Rwith the same mods.

As far as Toughness goes they do alright - remember the Hilux reputation for not dying! They really only make peak power at about 4200 according to the Ellery press books. That is on standard trim.

But as has been said there is not much you can do to make them rev more. What sort of power are you hoping to make from one by the way?

[bansheebuzz]

5500-6000 they will rev to but you need some good head work to make use of this rpm. In standard trim they fall flat after 5000 and intake, extractors wont help that, the big problem is in the head Anything can be achieved with money. Try lcengineering.com , they have alot of performance gear for the 22r

I read somewhere that putting a 20R head on them was the go.???

Where would one get a 20R head.???

[Screamn_Sleeka]

20R from 81-83 celica's, and probably similar year Hiace's, they have smaller ports, so will need porting. These engines arnt really good for racing, only benifit over ur 18R is they have a cross flow head.

i have not seen 20r in aus, plenty in usa. we had 21r in celicas and coronas

Thats true, use a 21 head, 20's are yankies, sorry thats where i grew up.

21R's are good for me,my sponsor has plenty of them.
will that head bolt straight on.? and will it flow better..
I can regear the car to pull about 6300 at the end of the straight if thats all the 22RE will do.

[bansheebuzz]

21r parts are a waste of time

[dale30]

21r parts are a waste of time

For any reason.????

[MWP]

For any reason.????

Becuase the heads have almost nothing in common with the 20R/22R heads other than itll fit.
21R heads do not flow as well as the 20R/22R heads, and they are known to warp a lot.

OK guys, this is the deal. In the US, they mod 2xR engines and ahve aftermarket support. Here, there really isn't any. There are 2 versions of the 22R, with different C/R, incompatible (without milling etc) heads, etc. We got the later version in '85 with the RA65, that other parts of the world (i.e. US) got along with later, TCCS EFI... but we got it with the older Analog EFI. My guess is that this is becasuse the analog EFI could be tweaked to cope without an O2 sensor - we were on leaded petrol at the time. Later 'ronas got the TCCS EFI, AFAIK. The Analog EFI is more 'tweak friendly' IIRC.

A 21R is similar to an early 22R, so the head wil not directly swap, AND it is not like a 20R anyway so there is no benefit from doing so.

The main ways to improve a 22R are extractors, cams, porting. Mild cam will work with unported head, as the stock cam is so poor, but anything more needs headwork. Cams would have to be bought from the US, really... I ran the specs of the Crow Cams 22R cam by the guys in the US and they we're impressed. Extractors can be bought here. If you did all this, I imagine the engine would be quite thirty and would have cost a bit... but at least it would be tough.
