I cant believe I'm suggesting this... but...
If it has the Holden Starfire 4 (aka Misfire, but anyway), it may be an easy option to relieve a commodore of a 186 or a 202, as a Starfire is essentially a cut down Holden Six.
As an engine swap, it is apparently no different to putting the six into a UC Sunbird Torana or a VB/VC Commodore.
It has been done before, but Im not sure how legal it is, esp. in regards to insurance.

u will find that the 21R will not be any quicker than the 1X so dont bother with it if u want more power..

by no means easy  but i am nearly finished my 1jz conversion. not very cheap either could try a 1g-gte as these fit into xt141's and xt130's. there is just enought room for my 1jz but i think it is about 100mm longer than a 1g.
later

i have done the holden six into corona conversion, and put simply, its a peice of piss...
so easy infact it took 2 ppl one night to finish, minus dinner and a whole carton...
what you need to do is
1) find a holden 6 preferrably a 186 or 173, less capacity makes it easier to register
2) fully rebuild it using all the holden inline 6 'go fast bits', or my engine this included triple stromies, high compression pistons, pacemaker extractors, yella terra head, *raise the compression even more if you dare, i had it hovering around 10-11:1* balanced shot peened rods and crank, 60 thou over, and a cam that'll show up on the richtor scale *the thinking man could get a 202 crank into a 186 blocked to fool the ppl at the road dept :D* ...
3) move the radiator forward, or cut the tailshaft down to size, but this means moveing the gearbox and shift lever back, not good becuase it takes more work
4) make up some mounts, i'm lucky to have a boiler maker as a mate so he helped me out, but any engineering workshop will makes some for a reasonable charge, (the going rate is usually about $40p/hour + materials) just amke sure you get the measurements right
5) use and engine crane to lower your engine in, bolt right up, (if you got your measuerments right) and go get her engineered
you also might want to upgrade your feul lines if your going to a wild six, but if you leave it pretty much standard(which will still haul ass) you should be fine...
pulled an easy high 13 second quarter considering its only a 1000kg car
cheap effective WRX scarer (not beater, it lost it all in wheelspin), i suggest wearing a tweed cost whenever driving to add to the sleeper effect
happy modding

sure would... i think the entire front end is the same as in the sedan or wagon version... just the back changes
have you got the M20 box or the W50 celica box? if you've got the W50 castlemaine rod shop sell a bellhousing and all the other stuff to fit a holden 6 to celica box for around $425 (a mate just got one actually) plus $35 postage to brissie, the M20 box is not a problem as its meant for the holden 6 anyways, but you might want to change to the clica box, 1st gear in an M20 is kinda useless - *2nd isnt that bad tho*... also mounts can be scavenge of any holden six or inline 6, you just need to make an adapter plate if you dont want some nice shiny ones that an engineer would make up for you
but yeah, anything with the starfire will accept the holden 6 transplant, they are indeed the same engine
i'm kinda kicking myself that i sold it for just $1000 to a guy that was gonna paddock whack with it, it was such a nice car 
i'll never forget those looks on the skyline drivers faces as i left the line sideways and sprayed rubber all over there car... ahh, the memories
BTW - i found that the sloppy progressive rate springs on the corona that came standard were better for traction, they really do squat on hard take offs... stiff prings tend to give a lot of wheelspin

Quick question.
How would you go about fitting a RB30 out of a VL commodore?

RB30ET is the VL turbo one
and yes, RB20DET (r32 one) is much nicer... crikeys, it'll actually crack some REVS! Although why a 1G isn't just as good, I really don't know, apart from the fact that every part and it's cousin is available for nissan stuff. Oh, and a 1G conversion would be relatively cheap too...

uhm... that might requires some more skill
its feasable, the corona have a surpringsly big engine bay...
i've never actually measured an RB30ET or RB30E up before so this is just an approx
1) get a set of the RB30 mounts, whack em on the XT130 crossmember, you'd ahve to see whether its got the clearance between the back of the engine and the firewall (i always leave 15mm between moving and non-moving parts...
2) if the gearbox is too big you'll need to massage the trans tunnel (might me able to squeeze in i think)
3) shorten your tailshaft (by alot i'd say)
4) radiator fowards, you might want to get a bigger one while your at it, not sure about the inlet and outlet for the radiator, they MIGHT be on different sides to that of the corona one
5) wiring loom and ECU have to go somewhere, behind glovebox in dash is good, they have a bit of room there, or behind centre console
6) exhaust clearance shouldnt be a problem, you'll need a bigger one than the 'granny spec' they come with
it'd be a very tight squeeze but i'd the RB30E would fit, the RB30ET would only be for the seasoned professionals tho...
although in my opinion, the RB30E wouldnt be that much better than the holden inline 6, and the holden is cheaper and easier to fit... plus the ammount of cheap peformance parts for the holden is insane, and replacements parts are dirt cheap...
mrshin is right, the 1G transfer problably would be cheaper than the RB (twin cam), but the holden inline would cost about $1000 all up including engine while the 1G would cost about $2000+ just for a 1G frontcut...
each to there own i say, but you wont beat the sound of a cammed holden 6 reaching 6000rpm

well.... yeah.... i cant argue with that
but they do sound nice when ppl spend some decent money on them, not these wanker 17yo types who drive VK commodores and the most performance enhacing mod they've ever done is getting a 3 inch exhaust

if your going to go a six in to a corona
do it with the 6cyl 4m that IS in a corona i flog heaps of commo's with the whole car stock i would be dead even with a Vk with extractors and exaust he'd beat me after 160
(this was done in a controlled enviroment)
but have fun finding parts

A Corona does not resemble a Corona MkII in any way. A 4M conversion wouldn't be easy and probably not too smart since they don't exactly have a lot of power for their size.

you can do it because it's a cheap upgrade and it's something different and it's a sleeper and there's parts a plenty for them and it'll hurt WRX drivers and upgrades are easy and you can build the engine yourself out of supercheap rebuild kits and need i go on?
it doesn't have to stay toyota powered in my book to get cred for doing something different. it's a conversion i've often pondered over.
the starfire comes in 1.9L and 2.4L yeah? then a 202 (3.3L) in then 2.4L car would be legal.

I think the starfire is only the 1.9L. The 2.4L Corona is a different motor altogether, I believe.
