had 1 of those corollas in the past
sold it because of the gear ratios
4th and 5th gear didnt have much difference...
getting back to the subject
try and find a ae112 sportivo front cut
TURBO
as for the supercharger
its been done in the past
and has had good results
but that was using a 4age? head
and about the reliablity i wouldnt have a clue
but if with the 7afte there wouldnt be a problem

turbo u say, sounds good, but price wise, whats cheaper, and easier, my guess is the turbo is easier, but the s/c cheaper yeah?
what about the ecu? will it be ok with xtra ponies? coz i dont wanna change it. a 112 front cut ay, is the 7afe in that car aswell?
as for 4th 5th gears, yeah they r a little close hey, i alwyas feel that 1st is too short aswell but otherwise it's a fun little car to race round in, wont be gettin anything better for around 2 or years, unless i win lotto, lol

turbo to me will perform better in the long run
( running bigger boost and even bigger turbo )
whereas supercharger the most you can do is change the crankshaft pulley to give you an extra couple of psi..
now for price wise...
depending what supercharger you buy and if its brand new or not it could cost you from $300 to $3,000
and as for the mounting, intake,etc etc..
whereas turbo the 7afte is already turbo all the oil supply lines and the injectors there all already there..
but um what can i say.. bang for your buck i would say turbo but its really up to you to decide...
now as for easier.. i would say turbo
because the sportivo version of the ae112 corolla already comes with turbo from factory... so it would have forged pistons , bigger injectors etc etc
as for the ecu. it really depends on if you can find and buy a front cut or not..
well when the ae112 sportivos came out they were $40,000? brand new ? around that figure and not many people bought them because they cost so much...
so finding a front cut or even a 7afte these days is VERY hard..
but if u do find 1 your VERY VERY lucky lOl
now if you do buy a complete front cut if will come with everything you need
ecu loom engine the whole support gear..
and you ll have spares for when you need it =P
your car at the moment is a 7afe
the ae112 sportivo is a 7afte.. t being turbo..
but its really up to you mate finding the engine / front cut is 1 thing...
the other thing people have done and that i was planning to do was either drop a 4agze or do a 1/2 4agze 1/2 7afe because the heads are nearly identical if not identical ( dont quote me on that )
now when doing a 7agze or 7agte you would need a 4agze head with pistons etc etc on a 7afe bottom end..
and you could use the 7afe ecu with a piggyback ecu..
but i mean the only real reason i sold the car was because of the gearbox..
i dunno about the sportivo gearbox but the 7afe 1 is really short lOl and with a turbo / supercharger its not gonna make things any longer...
but 1 thing for sure it ll b little pocket rocket  !
gees im really long winded haha 
well to cut a long story short try and find a 7afte engine or front cut
if your unsuccessful with it then either change car or save up for a 7agze or 7agte
and as for the 4th and 5th gear i always use to go from 3rd to 5th lOl because there really wasnt much difference..
and yes i do admit 1st gear is really low aswell i use to be hitting 6500rpm in 1st gear and only be going around 30km/h or something like that.. cant remember now but that car was a real dream to drive so reliable !! lOl
anyways mate if you wanna talk more indepth about anything pm me

This ain't gonna happen with a stock 7AFE bottom, you'll just end up smashing the crap out of the pistons or rip the big end bolts out of the con rod caps, 7AFE are not like the 4AGE where these bolt run right through the conrod end. 7A's are just a taped thread in the end. The conrod will last as long as you stay under 7,000 rpm, pistons, will need need to be forgies to get that power... Standard 7AFE + turbo only made 115kw from factory and that all they were... a N/A 7AFE with a turbo slapped on and a few extra's

Good luck finding these, as only 200 were made... and most are very pampered too as I'm after one!. Cheaper, ring toyota, get an exhaust manifold for the sportivo, search these forums forsale or jap wreckers for a 3SGTE turbo-CT26 (The standard sportivo are tiny-CT12 or close to it), 4AGZE or 7MGTE injectors , Supra 7MGTE fuel pump, A good FMIC. Get the bearings done in the turbo anyway, cause I just don't trust what people say, and for similar reasons, but a new fuel pump. ECU, well, I know a 4AGE will run a 7AGE, but not to is 100% capabilities, and similarly I've heard people running 7AFE, 4AFE's with 4AGE ECU, So you could try a 4AGZE ECU. I have never tried any of these as I've alway's gone A/M ECU-Microtech, EMS, Autronic or Motec. If you do run a GZE ECU, get the AE101 (again hard to find, but are around) which are map sensor, multi-coil packed, etc. This ECU will need to be wired differently to suit the 7AFE, but it can be done and most sensor are compatible. You can use Lancer or Lantra coil packs, which do perform better than the standard GZE items (I use them in my rally cars and other conversions now+ cheaper and easier to find) and what ever way, get a GZE box+CV's. The sportivo came with the standard N/A 7A box and I have change a couple now to a GZE LSD's and the owners came back much happier and I haven't heard a complaint about the Boxes or CV's blowing after a few thousand km's!. Plus much better ratio's for F/I.

Sorry to say, to us Toymodder's, that's technically what we'd call them or assume, but on the ADR and VIN plates, they're labeled as a normal 7AFE and the workshop manual as a sportivo 7AFE. This is beacuse the were specifically built for oz only
Search the forums as I have covered the 7AGE conversions many times in the past... In fact I have a blown one sitting and waiting a rebuild at this point in time and they aren't as straight forward as many people think, but interesting anyway you look at it.

good advice guys, way better than some other forums, they usually tell u to keep dreaming...... not worth it, blah blah blah, is usually coz they jack shit about it.
turbo sounds like the right thing to do, and my mates got a couple of 4age's in his garage, so i might go a full motor conversion, add some gze pistons then turbo that with the ct-26. he's been fiddling with his ae92 rolla for a couple of years now, says that combo has proved quite fun and reliable in the past. the bastard is currently building a 400hp monster 4agte for his ride, should be in the bay in about a week or say, will be awesome.
thanks again hey
Tim

you should just buy a 4agze instead of getting a 4age and putting gze pistons in..
it would be easier and less time consuming
well good luck and have fun

4 sure it would be easier, just depends, my mate has most of the parts, basically ready to go, is way cheaper to buy it all from him, and put it together here at home, old mans got the tools and know how, so between the 3 of us, we can get it goin, only expensivce parts really are the turbo, and manifolds... so yeah, thats why, else i'd just pay 4 a 4agze --> gte conversion.
mates rolla is in the garage, is taking 4eva, has been ther 2 weeks, and all they have done is wire in the new puter, havent even made the turbo manifold yet, prety bad when they told him 4 weeks start to finish hey
