Converting Gen 3 or 3.5 3SGTE to RWD.

[stidnam]

Ok after some info as below. I have a ST215 Caldina 3sgte with COP and I will be using the factory ecu etc.

1. Flywheel. As mine was an auto I need a flywheel. What can I use? So far I have come up with the following options. Use a ST205 one, or a 3sge beams one, or a custom one.

2. Bellhousing. I know of the 2S or 3Y bellhousing that can be used for a w5x box and that the 2S one puts the starter on the exhaust side while the 3Y one puts it on the intake side. Apparently the 4y bellhousing is slightly larger so you can run a bigger clutch??? What I am concerned about is the angle that these bellhousings will put the motor on as I've read that they put the motor on a lean towards the exhaust side where there is no oil drainage. This is directly opposite from the factory fwd setup where it is angled to the intake side.

Now I can use a AZ6 6 speed from a Beams 3sge and I am considering it at the moment but apparently they are only good for 300hp and the 3sgte makes 265hp stock which means it might not last too long. The plus is that the motor will be upright rather than leaned towards the exhaust side and don't forget 6 speeds for the wank factor.

3. Sump baffling. I will be using the 2s sump and have bought one already but as they have crap baffling from factory what kind of baffling is needed to make them better? I have sorted out the oil pump which will be a 5sfe one from a 98+ camry which will allow me to fit the factory trigger wheel sensor on it as I have the 3sgte with the coil on plug setup.

4. Turbo. The turbo and the exhaust housing are cast as one item on my 3sgte so I need to fix this. Options are use a ST205 ct20b, totally new aftermarket turbo, or try to get the exhaust housing off a ST205 ct20b to fit on my turbo. I am aware that the exhaust wheel is slightly different to the st205 turbo and the housing will need to be machined to fit nicely. Any recommendations of a good turbo shop in Sydney to speak to about this?

Thats all for now. Thanks

[stidnam]

No one has any suggestions? Mainly after a recommendation for a turbo workshop in Sydney that I can chat to about modifying the turbo and suggestions on how to baffle the sump properly

sorry dude, i havn't had time to respond to your PM.

1 Flywheel: use a ST205 or similar flywheel, if going aftermarket clutch (twinplate) then by an OS giken setup and it will bolt straight in.
i have a st205 fly if you need one.

2 Bellhousing: 2s, 4s or 3y will suit the application but check to see if the 205 ringear will fit inside the 2s bell b4 hand. forget the six speed, it will die fairly quickly if abused.

3 Sump: 2s wont fit unless you change the timing cover and redrill either the block or the sump too suit the application. gen 3 has a different pattern in the bottom.

i would personally stick with the sump you have and mod it to suit the angle change.

4Turbo: you do have the options you mentioned in which case i would see john at precision turbos (wetheril park) or

my personal preference would be to run a KKR or garrett GT series and only have to build the manifolding once (these will both work with a stock ecu)

What about oil pick up? im sure you will have to change that.

[The Real Roadrunner]

yep, when you mod the steel pan you also have to "twist" the pickup to suit the different angle.

i also modded the alloy pan on my engine but that was mainly to get it sitting as low in the bay as possible.

Thanks for the info. I will have to look at the stock sump and see what can be done with it.

i have a st205 fly if you need one.

cheers

Can you PM me how much you are after for this.

[stidnam]

I have found out that the 2s bellhousing will bolt up no worries but the 3y one needs to be modified a bit for it to fit on.

Apparently two of the bolt holes don't line up and need to be slotted somewhat. I think that the bellhousing itself (as well as the 2s one) also has to have 5 or so mm removed off the faces so that the input shaft slots into the flywheel bearing correctly.



Can anyone using a 3y bellhousing confirm the need for slotting the holes?

[The Real Roadrunner]

check TwentyEights RA28 thread for sump mods (not as modded as mine but it will give you the basic idea)

EDIT, yes 1 hole will need to be slotted for a Yseries bell (not sure about 2 of them though)

i can get Leeroy to measure the overall bellhousing length his was machined to. this would suit any application using a W5# and std style clutch (or any aftermarket twinplate)

cheers

Input shaft sat back from the front face of the bellhousing.

[LeeRoy]

I dont have a measurement of overall length nor do i have one of the bearing used. Linden will be able to tell you the bearing info and im sure you can work out overall length of the bell from the measurements ive given if you just go and measure the input shafts length.

Hope that helps,
Leigh

This is very helpful. + rep for you

I've got a 3y bellhousing on its way so should start playing with that next week. Am contemplating doing so drastic surgery to the 3y bellhousing to fix the lean that it puts the motor on as I don't really like the idea of it. Also would mean that the sump wouldn't have to be modified. I will have to test position the 3s in the 22's engine bay to see how much room I have to play with. Lucky on my 3s I don't have the dizzy poking out the back of the head.

I took the turbo off tonight so its off to the turbo shop for a bit of show and tell to see what he says as it was the usual story over the phone "hmm not sure mate bring it in and we'll have a look".

[stidnam]

Test fitted the 3y bellhousing to see what needs work.

Top left hole



Bottom two holes if using the factory alloy sump bit.



Does the s series bellhousing have the same issues with the bottom two holes?

On other news John at Precision Turbochargers has managed to find a exhaust housing to suit my CT20b so I'm in business. There is a slight clearance difference now but John said that he has seen a lot worse and that it will only be a slight bit laggier as a result. So we will see I guess.

[oldcorollas]

why not put your CT20B in the on epiece exhauts manifold/housing?

ie, if you are sticking with same series internals..

the St205 has steel wheel? the dinas make more power and torque than 205 stock don't tho? = 205 turbo backwards step (unless 205 is not ceramic?)

[stidnam]

not exactly sure what you are asking but the turbo that I am using is the stock ct20b off the caldina. It is very similar to the ST205 ct20b except that the exhaust wheel is slightly different and the stupid one piece manifold and exhaust housing.

What I am doing is replacing this one piece horror with a normal housing so I can point the turbo the correct way for rwd.

I don't see the point of putting the internals into a ST205 housings if thats what you mean.

[oldcorollas]

ahh, so you are keeping the CT26 guts off the dina and turning around.. right..

i thought you were using the pahntom CT20b(26) off the 205 to get away from ceramic turbine...
my bad
i spose you could be creative with the dump pipe
