Want to put a SR20DE into RT142 Corona

Hi,
My gearbox is about to go craptise and was thinking about doing a upgrade.
How possible is it to put a SR20DE into a RT142 corona (with IRS)?
A front cut is $2000
How much extra would it cost to get it all professionaly fitted?
I would probably be able to keep all the brake stuff and diff (which is from a ra65 celica), no?
From what i've read, the sr20 is the way to go, all alloy block, VVT, blah blah
The 3SGE looked like too much extra stuffing around to convert to RWD.

you can kiss the best part of 10k goodbye if you are unable to do any of the work yourself.

dude... much easier, cheaper and WELL DOCUMENTED conversion would be the 1G-GTE from a GA71 supra or similar.
These are a 2L, inline six twin turbo. HEAPS of people put them into their RA23/RA28 celica's (there are at least 5-7 on this forum i can name immediately)... and you having the 22R-E have similar engine mounts etc making it even simpler than into an old celica.
Reason being you already have an EFI tank, W55 gearbox (same externally as W58 AFAIK), and a strong(er) F series diff which can be upgraded to an LSD.
A decent 1G-GTE front cut will cost you less than $3000 easily, and will be 100000 times easier than the SR20DE. Faster too

I put a 1GGTE into an ST141 (carby version of the RT142). If I had my time again I would have chosen a different engine - either the SR20DET or a 13B turbo.
You can fit the 1G but it's just that little bit too long for a nice fit. It will upset the handling as a lot of the weight will be right up the front of the engine bay, and you will probably also run into some cooling/overheating issues if you are not careful/lucky.
Definitely go for a smaller motor, and don't listen to anyone who tells you it's a shit idea.
HOWEVER I think it's a shit idea to put an SR20DE in. If you're going to the trouble fit the turbo motor. I know numerous people who have done atmo conversions and they all end up kicking themselves and wishing they'd spent that little bit extra to end up with a really cool car.
RA65 celica brakes will be fine.
Oh, and watch who you take advice from. Particularly people who don't even know what model of car a 1G came from (GA70 not a GA71... which didn't even exist). Also, you'd be an idiot to pay more than $2,000 for a complete 1G half cut.
If you want information on the 1G swap, send me a PM... but I still recommend an SR20DET or a 13B.

someone saying GA71 instead of GA70 shouldnt be discreditted... thats just bollocks. I'm sre I'll fit the 1g in to the corona engine bay just as easily as a celica engine bay.

I was just pointing out that not everyone giving out advice should be. Listen to what you like from who you like. But I have given my warning and that's that.
The reason I pointed it out is that there are three things in the one post that seem uneducated (indicated value of a 1G cut, getting the Supra model incorrect, and stating that a 1G conversion is easier than an SR conversion. I have not done an SR conversion into a Corona, but I can't see it being 100000 times harder, if harder at all)

I also did not say that a 1G would not fit, I was just saying that it's not an ideal fit, and will probably cause some issues if you drive the car in traffic or have any track aspiratons. It will sit too close to the radiator, even when mounted as close as feasible to the firewall without undertaking a clutch master conversion.
Believe me, I've done it.

i would go for the sr20t
better poerformance lighter etc
easy to get aftermarket parts for them
the main extra costs that the sr would cost u
is making of engine mounts maybe and few little extras like tailshaft and stuff
i recently wired up an sr20t into a gemini
was a neat little fit
once u piss of the pwer steer pump and the a/c from the engine its a nice compact fit
if u know someone who can fabricate mounts then u could get the job done cheaper

I would be interested to see a split wieght comparison of "before" and "after" a 22R-E to 1G-GTE conversion. A similar topic (weight of 18R vs 1G-GTE) has be trashed out a few times anyway.
Now as for my comments. Perhaps some "uneducated" statements were made... but i hardly find

to be an uneducated statement, pretty much every 1g-gte front cut i've seen has been under $3000. 
Getting the supra model incorrect. Oh boo-hoo. Really! I had a slight mix up with the whole MA70/MA71 thing with the turbo and non-turbo. My bad.
As for the statement that it's 10000 times easier. Ok, that was an overstatement/exaggeration. But i thought that would be obvious......
7M-Brisbane, some personal advice from me is to ammend your attitude to a more friendly one. They are usually more welcomed by the general community.
