Converting an ST141 in to an RT141

**Starfire** · 20-09-2006, 11:33 AM

Hi Guys,

I did a search but couldnt find anything specific. Let me know if I missed something.

One of the guys here at work has an ST141 wagon which has more problems than I can be bothered dealing with (timing belt, water pump, head gasket, ignition leads, blah...)

I know where there is an 18RC (from an RA28) lying around that would do the job but am unsure what needs to be changed to make the R series engine fit.

I would assume that I need a crossmember and bellhousing at the very least. Is there anything else that needs to be changed?

What can I expect to pay for the parts to do such a conversion? This needs to be cheap!

Labour isnt really an issue.

Thanks,
Terry

Um the 18rc would be worse then the 2sc, why wouldn't you do a 22re conversion, buy rusted out RT142 for 200 bob if that and change everything over.

Or just find another 2sc and drop it in

Because I have an 18rc sitting there.

That said if you can find me a RT142 for bugger all I might be interested!

I only clicked this cause you cant see the whole name and i thought it read "Converting an ST141 in to an GT141"...
But anyway, dont go the 18R-C, its the worst, either 22R-E from the celica/corona, or a 21R-C from the RA60 celica. 21R-C over the 22R-E if you dont want to have to do heaps of wiring and efi pump etc, although if u got a full 22R-E rona ud get everything u need, including less weight with your live axel.

EDIT: But ANYTHING is better than a Starfire!

please .. think of the children ... don't make your life any worse - bin the 18RC and put a proper motor (one with a crossflow head and EFI) in its place.

there are eleventy bagillion running road registered grandma coronas for sale so cheap they are almost paying you to take them in the trady and on ebay

my question is why go to so much trouble? just buy another one that is actually good
