3sge Conversion Into Xe7x Series Corolla

[Run Free Ke70]

hey all

 

looking at buying a ke70 or ae71 and daily driving it stock for a while but then looking at 3SGE conversion. or is it better to just go with 4AGE? what is involved in the conversion from 4K to 3SGE? mounts/crossmembers etc

 

thanks

[beerhead]

I've started a gen 2 3SGE convo in my KE70.

 

Needs:

Custom crossmember

Factory SA63/ST141 metal engine mounts (I'm modifying AE71 rubber mounts to suit)

SA63/ST141 2SC sump and oil pickup

Cut and shut manifold

Custom extractors / Nasty 5SFE fwd cast manifold with rear facing collector

Custom gearbox Xmember

W55 from an SA63 or bellhousing for use on another W5X box

Custom tailshaft

Aftermarket ECU or custom module for wasted spark on factory ECU

 

If you want an easy conversion, I'd look elsewhere, but it would smoke most 4AGE's - torque wins races!

thanks mate! how pricey are these parts as well? they seem like fairly common parts i.e. st141 stuff and celica stuff! but yeh intend to drive a ke70 around for a while as a daily and then do a conversion down the track. u doing this urself or getting a workshop to do it?

 

and i'd go W58 gearbox as a guy on ae86dc had a w55 and it shat on him! how do u do these custom crossmembers and tailshafts etc? urself or go to a shop and ask them to make for you? i know ca and sr conversions use custom crossmembers and tailshafts but i plan to try keep it all toyota!

 

doesnt seem too bad! most of the work would be done by workshop i think. as I'm not heaps cluey with motor conversions!

don't mean to dishearten you mate but if you are planning on gettin a workshop to do it all imho i wouldnt expect to see much change from 15 grand. might seem crazy but ask anyone who's done a conversion and they'll tell that costs always go way over what they were expecting... it'll be a crazy car if you do it but it'll burn a massive hole in your pocket...

[beerhead]

I bought a complete SA63 to strip for all the parts I need cost me $400, and I sold the rest of the panels are spares for what I bought the car for. If you take your time collecting the parts it'll save you a fortune. At the moment my conversion has cost -$100 including a nanna spec KE70. I'm doing most of the work myself, so I'm hoping to have my conversion going for around 2 grand.

can we have this moved to the tech section?

BTW there is a way to get a 3SGE on a 2S bellhousing without shaving it. Not sure I should let the cat out of the bag or everyone will be doing this conversion once I show how easily it can be done :wink:

18mm spigot bearing ?, my biggest question as I'm doing this too :wink: is, whats the deal with the flywheel.

 

Use the 3SGE flywheel or a custom one is required ?

<----- these have the 3SG-E and 6speed box, facing the right way, just drop it in...

 

 

You can get someone from Altezzaclub in NZ to buy it and box it, you just have to get it through Customs at this end.

 

There are two emission levels, the '98 to '02 had GF engine models, and '02 onwards had GH engines.

 

The GF have just reached their ban date going into NZ this month, GH engines should be good for plenty more years yet.

[altezzaclub]

..and $350 buys extractors for the 3SG-E in Sydney!

..and if you get to Orange sometime you can measure everything on mine...

We have a thinker ! Got it in one. Use a double row bearing :wink:

 

Many people don't realise that the crown wheel on a flywheel is compression fit. You just need to make a jig and heat up the outer ring with an oxy and hammer it off.

 

Let the flywheel cool down, then reheat the crown wheel. Put the crown wheel on upside down so that the rounded edge teeth for the starter gear is facing the starter in RWD config. Hammer it back on with a punch on a flat sheet of steel. Many people get a custom flywheel, but it isn't 100% necessary.

The Beams 6 speed is too tall for a standard KE/AE transmission tunnel, so it won't just drop in, firewall mods, be it sledge hammer or welding will be required for a beams swap to have the weight where it should be.

dumb question but whats the jig for? to knock it off evenly?

[beerhead]

Yep, they're on there tight. I think the best jig is a hydraulic one. Have the flywheel sitting on a piece of 10mm plate with a oxy cut hole that the flywheel can fall through, but catches the ring gear. Have a small frame over the flywheel and put a jack on the flywheel so that the head catches on the frame. Put about 200- 300kg of force on the jack and heat up the ring gear in a circular motion. In about 5 minutes the ring gear should be getting a little pink and at that point keep jacking the flywheel till the flywheel pushes through the hole leaving the ring gear on the bench. The fitment is a reverse process.

 

I've heard it is possible to do it with a punch and an oxy, but this dude could put a wheel bearing cup in a hub in 3-4 hits with a punch... so I think that most people couldn't pull it off.

[Sam_Q]

neat, sounds like a bit of work but it sounds worth it. Now why would something like a W55 need a longer spigot at all with the 2S bellhousing? Isnt the 2S more or less the same block holes as the 3s beams?
