For the love of a tractor engine: The life and times of the 18R-G

[RA35GT]

I prefer the 88251 due to the integrated balance tube and no coolant runs through the manifold.

Ok so i thought i would open the plastic bag with a carby in it and have a crack at putting it together. Mainly wanted to see if anything was missing. I have only ever pulled a suzuki carby apart once and it was significantly less complicated.

What i found inside the bag


after some fiddling


the few leftovers. any tips on where i missed these?

[leso]

taff... i have a pair of solexs you can have to pull apart to find out where the bits go...i live in ipswich dont know if that is any help ..

cheers leso

Just finnished reading this whole thread took a week and all i can say you guys areas legendary as the 18R-G itself be careful with the space time continuum

oh and on a side note wish this info was around in the early 90s when i played with these motors might of not fuckt so many doing the trial and error thing

[cheviotrola]

Will ramtubes for weber 40's fit stock solex's?

[Zammo]

yes they should

[o_man_ra23]

Zammo, without people doing the trial and error thing in the 90's, a lot of this info wouldn't be here today. There may have been less trial and error, but that may have lead to less great ideas coming through. So your pioneering efforts are something we all have to be thankful for.

The leftover springs look like the ones on the accelleration pumps.

The funny o rings in the picture are from underneath the jet block (big bit in the centre of the float bowl that the jets screw into.
You'll want to have those in place if you're planning to use the carbies.
I agree with oman that the springs are from the accelleration pump push rod.

The ball bearing goes in one of the vertical holes (looks like a screw hole) under the fload bowl lid (the big lid). There should be two balls and two springs under or over the balls (I'm having trouble remembering).

Those little brass plungers will go somewhere in the accelleration pump system, inserted into holes from the top.

look what i found
18RG HKS TURBO ORIGINAL BOX - 1976 77 CELICA RA28 RA23 TA23 RA25 TA22 RA29 2TG | eBay

[o_man_ra23]

Not sure if that is the first I have seen on fleabay... the owner may need to reduce their pot consumption, or check out auctions worldwide more regularly.

[2004lowlux]

possibly......i also doubt its the only one thats been up for sale ever but its the first one ive ever seen

[Rens]

Another engine for sale on Ebay if anyone's looking.
18rg | eBay

[2004lowlux]

yeah i seen it i wanted to see if it was worth getting it, taking the cams and pistons and using them in the geu if ive got it right itll have more cam duration and higher compression obviously not series one stuff but still a bit more than whats in it so far and for 300 bucks? chit yeah! so dont tell anyone lol!
been reading a few tech notes i found on google theres mention a 4age ecu can be used on the 18rgeu its probably already mentioned here someplace my appolegies if so but seriously this thread is rocking 205 pages! itll take me a week to read it all.

[o_man_ra23]

Interesting engine... good condition and hasn't been started in 4 years seem a little like distant cousins to me.

The head number won't necessarily tell you what pistons are in there. There are a good many engines which have had heads lobbed onto RC blocks with 9.7 pistons isntalled back when those pistons were still available (remember, these engines were well and truly punching above their weight in the 80's and early 90's). So one can only hope that you would get 9.7 oversized pistons with an engine like that.
