Brennan Posted October 5, 2014 Share Posted October 5, 2014 What sort of things do you want to know? Altezza 3sge and 6 speed? First of all be prepared to spend a lot more, than if you were to go with something like a 4age. Especially if you go with a link ecu. Be prepared to cut the gearbox tunnel and maybe the firewall. Will probably need a ke70/Ae86 sway bar to fit around the sump?? Engine mounts are pretty easy to make. Use the altezza rubber mounts. gearbox mount will need to be fab'd. and the shifter will be about 300mm further back? hope that helps Quote Link to comment Share on other sites More sharing options...
krazy Posted October 6, 2014 Author Share Posted October 6, 2014 I was planning on using a w55 or w57 with a y series bell housing which should fit with out modification or very little and is the factory ecu that hard to use as have read they need a speedo input which shouldn't be that hard to overcome also a throttle switch on the foot pedal for the electronic throttle body, did you have problems with the height of the engine thanks Quote Link to comment Share on other sites More sharing options...
Roman Posted October 6, 2014 Share Posted October 6, 2014 Save yourself a ball ache and just run the 6 speed with all factory bits. Using any of the W bellhousings means custom/spaced out flywheel, (or machining bellhousing) ring gear modification and some other mucking around. The only benefit would be if there was a significantly improved shifter position, but that depends on which W box you get. Regardless, your engine swap will likely go like this: 1. Cool, cheap engine with 200hp! 2. Tries to fit engine/gearbox, transmission tunnel needs enlarging. 3. Tries to fit engine, intake manifold doesnt fit. 4. Not to worry I'll convert to quads $$$$$$$ 5. Returnless fuel line is a pain, need custom FPR $$ 6. Tall motor, sump needs modifying $$7. Exhaust manifold needs to be remade $$$ 7. Now it needs an aftermarket ECU to run right $$$$$$$$$$ 8. Tuning dual VVTI $$$$$$$$9. Car needs cert $$ 10. Fixing any cert issues $$$$ 8. Now you've spend $10k haha. Super fun though! But definitely not the easiest or most cost effective swap. For same money spent, you could instead bang together a nice 4AGE NA or turbo setup with the money spent on fun bits rather than sorting out packaging or ECU issues. 2 Quote Link to comment Share on other sites More sharing options...
pbaines Posted October 6, 2014 Share Posted October 6, 2014 After dropping a 4A-GE into my KE30, I realised there was a lot more shit to do than I first thought. Putting a beams in a KE25 will be a tight as fit. All though planting up a W57 will retain you the same shifter hole you will still need to modify the gearbox tunnel. Lots of $$$$$ required for a beams. Doing a 4A-GE on the other hand is super simple. time consuming but very simple 1 Quote Link to comment Share on other sites More sharing options...
krazy Posted October 7, 2014 Author Share Posted October 7, 2014 im not to worried cost wise most of the work I can get done cheap through work, do it myself Quote Link to comment Share on other sites More sharing options...
Truenotch Posted October 7, 2014 Share Posted October 7, 2014 The advice in this thread is good. I've done it both ways so far and the 6 speed option was by far the easier option. We also did a complete conversion on a friends ST142 Corona Wagon using a standard loom and it wasn't too difficult. The best way to do it is to get a full conversion - Engine, loom, ECU, clutch/fly and 6 speed and put the whole lot in place. Keep the loom as complete as possible until you get it running and start chopping wires bit by bit until you have a "bare bones" loom. The factory clutch and dual mass flywheel are fine for a road car, but solid fly is a good change if you can find one for a good price. 1 Quote Link to comment Share on other sites More sharing options...
krazy Posted October 8, 2014 Author Share Posted October 8, 2014 I bought the engine as an auto conversion but ditched the auto so I have to buy a clutch and flywheel anyway so no point going for a dual mass did you use factory loom and ecu or did you use an aftermarket computer? thanks for all the great advice and sorry if im asking to many question Quote Link to comment Share on other sites More sharing options...
Brennan Posted October 8, 2014 Share Posted October 8, 2014 @krazy, I hope you realise the auto engines are different to the manual engines? Different Valves & compression if im not mistaken. 6. Tall motor, sump needs modifying $$ 8. Now you've spend $10k haha. Not sure about earlier Corollas. but i didn't have to mod the sump. And the bonnet slightly touches the plastic cover on the top of the engine. Shit, I did most the work my self and i spent a hell of a lot more than that haha Don't want to put you off, but is a big commitment. I have no idea how, but it easily took me 2 years to do mine. if i was to do it again, i would go with a blacktop 4age & altezza 6 speed. 2 Quote Link to comment Share on other sites More sharing options...
Roman Posted October 8, 2014 Share Posted October 8, 2014 Its definitely false economy to think that buying an auto engine for cheap is going to save you money. I had to buy mine all in bits and it cost a heap more. Getting a whol engine/trans/loom/ecu/airbox etc is best way to go. If your engine doesnt have the airflow meter and airbox youre already fucked if trying to run standard ecu. Which might have a mare if it sees the autobox is missing. 2 Quote Link to comment Share on other sites More sharing options...
CorollaGT Posted October 9, 2014 Share Posted October 9, 2014 Also auto 3S Altezza's had lower a compression ratio and less aggressive cams iirc Quote Link to comment Share on other sites More sharing options...
Brennan Posted October 9, 2014 Share Posted October 9, 2014 Getting a whol engine/trans/loom/ecu/airbox etc is best way to go. The enormous airbox with many vaccum lines and flappy flaps My "conversion' even came with the altezza clutch pedal which i modded and used with the altezza master & slave cylinder. only thing missing that i felt should have been there was the speedo cluster. (not that i would have used it) Quote Link to comment Share on other sites More sharing options...
krazy Posted October 9, 2014 Author Share Posted October 9, 2014 i know the autos are 10.5:1 compression ratio have stainless valves instead of titanium and less aggressive cams, the ecu shouldn't be to bad as long as it sees that the inhibitor switch is in park or neutral and an altezza pod filter set up will take care of the afm air box scenario. 1 Quote Link to comment Share on other sites More sharing options...
Celica RA45 Posted October 13, 2014 Share Posted October 13, 2014 auto comp is the same as the red top beams ,go get a 3y bellhousing or 2 s and you can still use the dual mass flywheel with the std 3y or 2s starter the altezza uses the same dia as the 2s rwd fly wheel any way ,same clutch and pressure plate from sa63 celica etc Quote Link to comment Share on other sites More sharing options...
krazy Posted October 14, 2014 Author Share Posted October 14, 2014 Thanks for that I have a y series bell housing on the way soon hopefully Quote Link to comment Share on other sites More sharing options...
Scottymac Posted November 28, 2014 Share Posted November 28, 2014 I am currently running a 3sge+ t in my rt104 corona . realy solid engine and i found pretty easy to fit in. im running a link ecu in mine i have run factory ecus in past conversions and just had troubles. im running the factory 6 speed with the shifter in the forward mounting position. its running 10 pound boost getting 196kw at the wheels makes the car pretty fun to drive, The engine is the cheap part its all the other bits and pieces that come in $200 or more lots that add up. 2 Quote Link to comment Share on other sites More sharing options...
EFI_LC Posted November 29, 2014 Share Posted November 29, 2014 I will be following this thread as I am doing a KP60 Altezza with Manual 6 speed. I am clearing out my garage currently so I can fit the Starlet and start on it maybe next weekend 1 Quote Link to comment Share on other sites More sharing options...
