RG manifold and a 3S FC question

[dale30]

Hi All
Back with more strange speedway questions.

New rules for our 4CYL class.

I can use my 18Rg if i can find a 2barrel manifold for it.Ive been looking around the wreckers but no good.
Does anyone know of a manifold that will fit with minor modification..??

If not im considering using a 3SFC but i would need a RWD gearbox to fit it..Any ideas for this one..

If i cant have that..

Whats the best performing 2ltr carby rwd.I was thinking about 2S from ST141.I can shave head and grind cam.

Open to all suggestions.

Hi,

I do not know of any manifold for the 18R-G other than the one's to take the twin side draught carbies. To put in anythign less would be a backward step and I guess that's why there is no such beast (that I know of) to do what you desire.

Sorry, I can't help you with the 3S engine.

why dont you get a 3S-GE and convert that to carb instead of an FE?

for the 3S you can adapt the bellhousing from a 2S-C in the SA63 celica i think, it's what most people do when converting an S-engine to rwd

I know this isn't much help but I remember reading on the old forums about someone doing a similar thing. They found some manifold (22r??) that almost fit the 18r-g ports. I have a feeling they had a 15mm adapter plate to make the ports line up. In fact I have a feeling it the manifold wasn't even Toyota but this is going back quite a while.

Is the 3SGE an import motor.?? And is there a carby manifold to fit.?

If 2S fits i can just bolt a complete ST141 gearbox straight in...Yes.?

Here is the carby rule that i got to run to..See what sort of fun you can have with this..

2ltr 8 valve no injection.
head shave,exhaust open,cam open.

33.Carburettor
Any standard factory single or dual throat Carburetor.
Manifold may be modified to accept adaptor plate. No adaptor plate to be more than 25mm thick. An extra return spring must be fitted to main throttle shaft.
Manifold and/or Carburetor may be fitted to injected motor with minor modifications

16 valve must remain completely stock except carby as above.

The 2S is a shocking engine.

Stick the carbie on top of the 18RG plenum? 25mm adaptor plate welded to top of plenum is easy enough.....will need a good hood scoop though

Hi,

That rule does not specifically state the number of carbs, therefore can't you use a stock 18R-G with its default dual carbs?

This question has come up before.

There was a Corona on eBay a year or so back with a 34ADM off an XF Falcoon mounted on an 18RG. I asked the seller about it, but he said it was there when he bought the car. The manifold did look like it was reycled from another engine. Sorry, probably not much help!

3S-GE is the standard engine on an ST162 SX celica. it has 103KW in standard form. The 3S-FE has 85KW and there is absolutely no reason to go for it over a 3S-GE.

though by the sounds of it an 18R-G would be much more easily adapted

[JustenGT8]

8 valve only so any 3S is out

16v allowed, but with less mods

Hmmmm

3S-GE sounds good.Been to my sponsor ( wreckers ) today and hes got a 3Sge there.
Looks like it will need a freshenup.
Does the dissy need the computer on 3SGE to control spark and timing.??

Is there a 2 brl manifold that will bolt on,or one that could be grafted on.???

And am i right in my assumption that i could bolt a gearbox from 2S st141on the back of the GE.

I cant belive id say this but the ford OHC 2 lt or a Fiat 2 Lt twin cam , rough but powerfull . Both these POS motors use a twin barrell webber that dumps the fuel in and this carby on a 2S or 22R works well .
