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

So the MS2 just takes in an input for a wideband controller like the WBO2 2CO, or it has the control circuitry onboard?

Takes a wideband controller input, i think. Not sure if the new V.3.0 PCB has the controller circuitry onboard yet (i have the v.3 board).... but im looking into that

If I remember correctly, SLEEKA used a set up from Injection Perfection.
It's been a while since I saw that car and it's show board, but I'm reasonably sure.

I reckon they've changed their design in recent years though, their current sets don't quite look the same.

[bullitt]

think he's reffering to EFI Hardware the company

Yeah..I't true TA-022 i mean EFI Hardware is 4trottle set up like side draft carb..Its same with Injection Perceftion..I like this EFI style..can get twin carb sound also..look classic..

Bullit,

Yep those Holley's sure are noisy pumps... Unless you've got a really loud car, I'd look elswhere. And like I said the Carter low pressure, high volume pump is the way to go

Part no: P4070

Thank a lots Ren..for info...

Here's another company, they're based in England, but their range is far better for sizes, lengths and all that.
It works out to about AU$900 for a pair of DCOE TBs in either 40mm, 42mm, 45mm or 48mm. The 50mm ones are more.

can someone post any info. bout differences between long and short 18RG manifolds? I've got a few ideas, but would rather hear from someone who knows, i've got one of each thats all. have some photos and serial no. of em both if need be.

[The Witzl]

one is short and one is long??

have a look at the first page of this thread, i think i pictured them both.

[smokem1]

duh....and i have seen your posts, sorry...i more mean performance advantages (if any). besides length/width the two are noticeably different, unlike my short manifold the long manifold i have (88220) has conical shaped ports with larger inlets and smaller outlets, like it was made for some more big ass carby's than factory or something.

[scootaphill]

as a side note on the runners.
i believe that teh 210 motor would have more torque due to the longer runners *however* im not sure how much more. its my understanding that the torque will rise with the length of the runners. in turn your top end improves with shorter runners.

cheers

i wish i had more time

I haven't got much to add on this other than some fitting issues.
I've also got one of each that were pictured. The long one doesn't clear an 18RGEU thermostat housing, hence the offset to the rear of the engine that the later, short ones have.
There are two different styles of long runner manifold.
The one pictured at the start of this thread has even length runners of even angle from perpendicular to the head.
The other long manifold allows for the engine tilting down at the back, and raises the runners on uneven angles so that the carbies both sit level. The throats still angle up slightly, but they are level front-to-back.
It also does not fit with the 18RGEU thermostat housing (without taking a file to the thermostat housing anyway).

The long ones were early models, 88211 and 88230 something, and so might not fit very well in an RA23/28 for clearance with the brake booster.

Hi, all...since i'm the one love a tractor engine..i guess this tread is right place to me ask question..i seriously going to rebuilt my 18rg,still colecting parts such a gasket set,engine bearing,piston ring and all part needed..my plan is to use 270 head to my 18rgr (230)..i'm going to buy metal head gasket,what are ticknees suitable for it..and is there needed or stick with odinary gasket ? Any help would be appreciate ?

megat-

[Norbie]

Unless you're building a turbo engine with lots of boost, there's no need for a metal headgasket - just use a normal one.

[bullitt]

Thanks Norbie..

[DQIKST]

hey guys.

i have a 88253 head. just the cams are adjustable just wondering what is the best setup??

(looking at my engine 1 is at the top and go clockwise for 2,3,4.)

which one to advance or retard??
what degree is the best??
hope that makes sence.

thanks

Along the lines of Steve's manifold post, I am attempting to use a short runner manifold on my 230 head but am encountering some issues. The balance tube is hitting a tab on the 230 head, pics below to explain:

250 head - intake side


250 head with balance tube


230 head - intake side (notice tab)


230 head (balance tube isn't going to fit without filing away that tab)


230 head - better view of the tab


Now this obviously wouldn't be an issue if I was using the longer manifold but I don't have one and the short one has already been match ported and bolted to the engine. Plus as Steve mentioned there may be clearance issues with the brake booster and the longer runners.

Just some info for anyone else who may run into this issue and also a design difference between the 230 and 250 heads (does anyone know what is supposed to bolt to that tab by any chance?). I can't comment on 210, 253 and 270 heads as I don't have any on hand.
