Sracin - the RT40 book, i want it.

SteveM,
yeah mate, got it in one

I call the funky chain runner / slipper / whatevers you call em; "Chain Guides", because they guide the path of the chain.

What you call the vibration dampeners, i call "tensioners" - because they set and keep the tension in the chain.

This is probably a well known fact by now, but I was told by an 18RG owner here in Perth that for the upper timing chance tensioner you can use a 4M item which you need to do a slight modification to in order to make it fit.

**SRacin** · 02-02-2006, 04:43 PM

yes they are the same as the old generation 1 18rgs, i knew there was something i was supposed to take of that 4m i took to the dump on sat..dam it..

**The Witzl** · 03-02-2006, 11:48 AM

new information is always good

I'll try to get my hands on a 4M tensioner and compare it to various 18RG ones i have, and post pics of course.

Oh, some 18R-GE wiring diagrams coming soon

I hope that you have fitted bronze guides OR had the valves coated or 20,000km will be more than they need to become trash.

Off topic reply, but technically important.

While you're at it, see if you can find an oil pump.
Early model M motors use the same rotor and possibly other parts as 18RGs.

u mean because they can lock up, if so, i have had some mods done to overcome that

Nice topic we have here.

New member to this board, like to interduce myself. I had a 77 liftback celica that went to car heaven (rusted like a bucket). But we pulled out the 18r-GU that was in there to put into a KE30 corolla (which we have done) The corolla is not registered (burnout car) and we have to do a rebuild on the engine..

What I have is a 18r-GU that was on gas. Now running Twin .45 Webber. The engine is a little tired and just need a new head gasket. I have found a company in NSW that have 18r-G head gasket and wanted to know if that will do. Is there any difference in the 18r-G and 18r-GU gasket.

Thanx for your time
Adam

adam - yeah mate they are the same

the differences between an 18R-G, 18R-GU, 18R-GEU are things like pollution controls, piston compression ratio, carbies/EFI... that sort of thing.

**The Witzl** · 04-02-2006, 10:15 PM

ok a few more pics....

Here we have a complete and running 18R-GEU. As per completed earlier this week

Hi all,
after 2 years of hoarding (and ending up with 4 RG's in various states) I finally got the 18RG in my RA23.

Attachment 580
Attachment 581
Attachment 582

So why do I post this here? My next project will be to replace the points with electronic ignition. I have an electronic dizzy from an 18RGEU with a bent shaft, but I decided to get rid of all mechanics and go ford (sorry) EDIS.
The hoarding part is over and the next step is to design and install the trigger wheel.
If anyone is interested I will share the 18RG specific info through this thread (or set up a new one).

I'm pleased to announce that I'm shortly going to re-join the exclusive club of working 18R-G owners.

Thanks to o_man_ra23 I'm now in possession of a fresh high-comp 18R-G, which will power the Orange Eyesore while I wait for the uber-engine to be built. I got about halfway through installing the engine today, but it was hot and I gave up.
