a whole heap of guys have done corona mods and are doing thm now too... best thing to do is SEARCH... figure out what exactly you want to do and search for it or just search the tech and conversion section
alternatively you can search member rides and find out who exactly has done mods to a corona and politely PM them and hopefully they will reply to you

did some say corona ! 
well first how much time and money do you have
if you want to keep the 2s engine which is crap as, buy some extractors, get the engine tuned proberly, service it, the usual things.
Many people have brought 1G-GTE halfcuts which are from supras/soarers.

The 1G-GTE would have to be by FAR the best bang for buck conversion you can ever do in a corona.
You would have to replace the crossmember with an RT142 corona item. Otherwise everything is damn easy.
Just buy yourself a GA70 frontcut, which comes complete with engine, gearbox and everything required to make it go BROOM.
Then you will have 2L, 6 cylinders, 24 valves and two turbos!

St has engine mounts for a 2S-C motor vs 22R-E motor. And as far as my feeble knowledge goes the 1G uses the R series mounts rather nicely yes?
The xmembers are probably very similar, just the engine mounts different

no idea about the actual mounts(cut and reweld) but I'm concerned about the xmember shape as you need a front sump for a rt. and note the engine bay is a little smaller than a celica one so you need asmuch room as you can get.

I got the feeling he was asking about modifications to his current engine.
Having owned one of these, I can point out quite simply that the are not and were never intended to be a powerful or inspiring engine. With that in mind, I would probably suggest that you decide (sooner rather than later) if you want to make this car a long-term project, or if you want something else.
If you want to retain the car, you will basically have to look at an engine conversion to make it even vaguely interesting an a straight line.
I assume that, having a Corona, you are on a tight budget. Don't stress, everyone else here probably is too. Most of what you hear is talk, the majority of people don't ever actually do anything major to their cars. What you can do on a limited budget is as follows:
Brakes off an RA60 Celica will bolt straight on with no problems at all - this whole upgrade will cost you about a hundred dollars. If you are a bit more serious, you may want to get the calipers reconditioned and also use slotted rotors and get good quality brake pads too. I can organise you a set of slotted for a good price, as I know of some for sale, so if you decide to go this way any time soon, let me know.
Suspension-wise, the first thing to do is take it to a suspension shop (a good one that has a few race cars out the front or inside, not Midas or a big chain store!) and get them to check it out comprehensively for worn parts. The bits to replace, before anything else, will be the bushes, ball joints, tie rod endds, and other perishable parts. Replacing these doesn't give you much to brag about, but it will make the car a lot safer and will make it respond to other mods better (eg the new brakes you fitted, when you fit new shocks, when you lower it, if you go to better wheels/tyres, etc). Chances are that any play in your steering, squelchiness on the highway, etc, is largely due to bushes, etc being perished. The car IS twenty years old after all!
Now, you can either get the parts and fit them yourself, but this is a fairly major undertaking and I would suggest that any beginner or modest amateur should leave this to a professional. It might cost a few hundred bucks for fitment but it'll be done right and you can't stuff anything up if you don't touch it 
Next you can get new shocks and springs (this is something you can probably do yourself with the help of a mate) and this will give you the biggest 'upgrade' - note that while this is the biggest upgrade you'll notice, it really hinges on you having done the bushes etc first.
Next time the car is due for tyres, don't be a tightass. Splurge a little more on the tyres - even if you only get a slightly better tyre it will make quite a difference over nasty/generic "Remington" or "Gemstone" type brands. Chances are if a tyre looks like it's from the 70's, it probably sucks. If it looks like a cool tyre, then it is probably better. Looks aren't everything, but tread pattern can be a clue to a well designed tyre. Money isn't everything, but price is also an indication of that tyre's stature in the model range. Don't bother spending $300 a corner, but an extra thirty bucks a tyre will make a huge difference.
Down the track you'll have more money and be able to afford an engine swap.. but by then you'll have bit-by-bit built a car that will accept the power you give it

The best thing to do engine-wise is make sure it's running well and that it doesn't break and cost you money just tokeep it running! The things you should look at doing are basic servicing items, it is at least in the state it was designed to operate it.
New spark plugs are about $3 each (so about $12 a set), new oil should cost you in the order of $30-$40 and an oil filter should be about $10. Also one thing to pay particular attention to on these motors is running good, uncontaminated coolant, and making sure the radiator, etc are all in good nick. A good way to check the general condition of your cooling system is to take the top radiator hose off the engine - if this is corroded then you could be up for a replacement engine, but if not then keep good coolant in it and it will go forever
Performance wise you may wish to fit an exhaust and extractors - probably some 4-2-1's and a 2¼" or 2½" exhaust from there back. Maybe run some colder spark plugs, good fuel (eg. Ultimate, Optimax) and crank the timing a few extra degrees... but you'll barely notice it and the thing will sound just plain ordinary. It'll also cost hundreds of dollars and will amke your car hard to insure

do some searching through the forums, you'll find a bit about your corona, and you'll also know the best people to talk to about it. they'll probly tell you to turbo it or do an engine conversion though

from all of the places i've seen on the web and in magazine ads, you can get a 1g half-cut pretty cheap. less than 2 grand. although, wiring on a 5m-e is a cunt so a 1g can't be any better! anybody wanna buy a cressida????

bank on spending pretty much 2k on a halfcut. and you will have to hunt one down, $1000 on a exhaust thats your 3k spent.
I put my 1g which i already had in my corona, spent 1000 on exhaust 450 on clutch. another 350?! on bits and pieces. still have a few things to do but like sway bar another 3-400 and diff(lsd) oh and the brakes i got for free. but that could be another 50-100 depending what a wrecker wants. it all starts to add up quite quickly.

CrappyCorona - Basically if you have $5000 you will have this conversion pretty much covered. I have already sent you a PM regarding this (would help if you filled out your location too buddy).
Wiring is easy if you know what you are doing.

Spot the guy who's never done an engine conversion
You won't even get it done for close to that. Things add up very quickly and I wouldn't expect much change from five grand on a DIY job. This guy doesn't seem to have much mechanical knowledge, so I'd suggest he would have to pay someone, so maybe another two grand on top of that.
A Two grand half cut is $2100 by the time it's delivered. YOu need new oil, coolant, plugs, filters, etc so you're looking at another $150 there. Exhaust system is a grand, fuel system another $500, intercooler piping is a few hundred bucks and I'll assume he would just run the stock cooler. Engine mounts, sump & pickup modifications, custom tailshaft, wiring............

Absolutely, that's what I used in my 1GGTE conversion, but to be honest I would be a bit sketchy about running a modified turbo engine on one (not flow, age) and would probably recommend using the RT142 tank with a new fuel pump of some description.

The first thing I would mod if I owned a Corona is the song "My Sharona" by The Knack. I'd drop a "My Corona" conversion into the chorus and do lots of laps around the block with it pumping out of the stereo.
Heaps cheaper than a 1g-gte and the car would be cooler as well, coz it has a song about it.

Yes, but I don't see any problems with the output of the Corona pump - they are probably the same part number anyway! They definitely look exactly the same.
The main concern is still age, so an MA70 pump is still 15+ years old...

I have the same motor in a different car and would like more power but not so much that it will blow diffs and things like that. Juyst enough power for a decent burnout and to win a few drags .

I assume that say if u r doing a 2 wheel burnout in 2nd gear it's like cruizing along normally in 2nd ie the stresses placed on the drivetrain. Naturally this is after the tyres have broken traction

Most go pop because the engines get over revved and overheat.

$1000 for an exhaust system
i can get a GA70 halfcut (well everything out of a GA70) for less then $1300 since it's my friends, free towing (friend), friend to do wiring, havn't asked anyone about an exhaust system but would think it's cheaper knowing a friend in the business.
RT142 Corona TailShaft (if st141)
RT142's Surge tank,Lines & Pump (if st141)
sump
oil pickup
engine mounts
brake upgrade
FOOLY SICK sticker across the window

intercooler piping I spent 100$ on 2" pipe and made my own and had some high pressure 2" hose for the connections so I'd bank on atleast 100-200 there depending.. someon people go to importers and try score free/cheap factory cooler pipes but I ran my 2" pipe through the factory holes behind the headlights.
radiator.. currently I'm running a modified standard one with the outlets moved and it'll be fine for winter and engineering but come summer I'll have another solution for this. oh dont forget thermos.
custom clutch line, I used a braided line but you could just have a new one bent up. you need to remove the old one as the rear turbo is that far back it almost hits the firewall right where there is a stupid looking fitting for the clutch line(no idea what it does)I had this from when I put it in my celica, cost 100$
you'll need something to control the thermos
I moved my battery to the boot, so needed cable and fittings for the cable(I spent 30$) a batter box(20$)
power steering lines, if you have them. I got away cheaply with a $6 length of hose and one fitting being changed think it was $20. (completely custom work can cost lots for p/steer, so just pull out what you have and thing how you can get away with the most minor mods, mine is not super neat but it's all under the afm and inlet pipe anyway you cant see it.
with the exhaust, if your using a p/s model you have trouble getting round the steering knuckle/joint but it can be done.
accelerator cable. the rt142 is too short I used one from a mx62 I think (25$) and was a headache cos it was slightly different, was easy once I got the shits and cut down the mounting bracket.
fuel lines. they come out in the engine bay on the wrong side. but the rt142 does have a larger supply(good thing) I reshaped my one and came out on the passanger side. but i needed to buy some longer efi hose to reach them.
that'll do for this session.

Come on Norbie. Both you and I can attest to the fact that a conversion costs only as much as the halfcut and a tank of petrol.

Sorry GT I forgot. We worked out that formula some time ago as I recall!
No wonder so many people are doing engine conversions these days.

you could always attack the front of your car with a chainsaw and weld the halfcut on
p.s. not to be taken literally

I have a RT142 and have recently fixed suspesion and have found a great improvement and eliminated almost all body roll. Also lot safer in wet. For this I bought Heavy Duty Dobinson springs form whiteline $320. Monroe Gt GAs front struts and Kyb rear shock $260 for shocks.
I have since got new tyres and the grip level has increased phenomonly. The car is fast enough as it is, I raced my friends XR6 auto and he could barely keep up.
Fix suspension first and then go about performance mods.
PS 22re are not gutless and theres always something funny about kicking people's arses in a stock looking corona.
