2T/3T bellhousing same as 1G. confirm Rumour?

[GTtwin]

Guys,
Everything (well most of it) i have posted is incorrect, Im sorry, i was repeating what i had been told, last time i listen to that person, sorry for any confusion it may have caused

Tis all good, thats what forums are for. I've certainly got alot of clarification outta this thread.

S being the same as G was not a rumour that I head, it was my own stupid conclusion I made when trying to measure the bellhousing/Block when it was still in the car. Makes sense in hindsight with the 2S having a longer stroke.

[TheToyman75]

The J160, 1G series bellhousing and 3T-GTE bellhousing all have the starter motor in the SAME place. (Passenger side).

As mentioned above it is the slave cylinder that swaps sides. (And yes all 3 are in my garage)



CHB, I wanna hear more about the flywheel and Clutch combo ?

CHB, I wanna hear more about the flywheel and Clutch combo ?

So do I... finally found someone selling a J160 locally. Not cheap, but cheaper than shipping one overseas.

According to xtreme clutch, J160 input splines are the same as W-series.

http://www.toymods.net/forums/showthread.php?t=43542 implies 1GGTE flywheels bolt up to 2T/3T crankshafts??? So that would be the setup of choice for forced induction T-series on J160 then...

Then maybe I should get the 1GFE flywheel with the gearbox, even though it's a dual mass contraption. Cos 1GGTE flywheels are hard to find locally... and heavy b*tards to ship. A 1GFE still takes 225mm, miles better than my 190mm 2T clutches.

Can anyone confirm G-series flywheels bolt up to T-series?

Other setups maybe? Don't say 3TGTE... you know we didn't get those either

So i realise the j160 came behind the 1g in the is200, and i know the gearbox looks very much the same in the 3s/beams Altezza jdm is200. But are the housings completely different or will a gearbox from a altezza bolt to a t series motor as well?

[japlish]

not sure if i'm on the right track here but i've looked into this too as i personally have a 3t and 1g bellhousing.
clutch wise i was going to use a 3t pressure plate with an older 200mm clutch disc from a rt104?? corona (i think thats what my excedy clutch book said??) and a 3t throwout bearing....

3S J160 has different housing (bellhousing is integral) to the 1G version and they do not interchange.

I guess that should work, a RT104 would have had a W-series gearbox and therefore the correct spline. Then a 3T pressure plate would fit the 200mm version of the T-series flywheel.

Not a good option for my forced induction plans though.

I do have a 200mm flywheel but that would have to be machined since it's been used all its life with a 190mm clutch. Still I wonder if it's worth it. So... confirm/deny G flywheel fits T?

[web]

I guess nobody is sure, so I got off my lazy arse, realized my 1GGTE may not have a flywheel yet (said flywheel is currently at sea and probably being stolen by pirates as we speak), but DOES still have its A/T drive plate. So I dug the 1GGTE out of the back of the garage and bolted its drive plate onto a 2T.

Amazingly, it seems to fit perfectly.

- hub bore is a match; a snug fit, as it should be
- all 6 bolts screw right in
- same # of teeth on ring gear
- same distance of ring gear to block flange (mind the spacer behind the 1GGTE A/T drive plate though... the drive plate needs that to line up properly)

Even the bolts are the same thread and shank size. Only the bolt heads are 14mm for the 1G A/T and 17mm for the 2T M/T, but that's about all the difference I could find. OK, the A/T bolts are shorter too - a flywheel is thicker than a drive plate after all.

I can get a 1GFE dual mass flywheel cheap... probably not the most desireable flywheel but it should work... and takes a 225mm clutch. Thoughts? Yeah, a 1GGTE flywheel is probably better, but they were never sold or imported here, so I'd have to get one shipped from overseas... which currently does not come cheap. Is it worth it.... or is the 1GFE dual mass okay to use?

Good research Web, next thing to check though is confirming the FE flywheel pattern is the same as the GE. I have no personal experience with the 1G, but the A series for example does have different bolt patterns across versions and the S series has similar variations. Are you able to borrow the FE to confirm?

In both A and S series, that's 6 vs. 8 bolt patterns IIRC. Pattern changed for a good reason - extra strength.

From EPC I gather the FE flywheel still has 6 bolts. It wouldn't need extra strength anyway. But of course that's no guarantee.

I can do limited measuring on the FE flywheel before buying, but unable to borrow. I could take the drive plate with me though, or even just its spacer and a few bolts. That should be enough to confirm at least the bolt pattern. I'll do that, then - thanks for the warning.

[web]

Well, I made a lowball offer (the guy simply seemed to want it all gone) and bought the lot, including a 1GFE engine that may someday donate some other useful bits like starter, alternator and such to the 1GGTE.

Already confirmed that the driveplate spacer from 1GGTE matches the 1GFE crankshaft pattern. Haven't offered up the dual mass 1GFE flywheel to a 2T yet, but that's what weekends are for. Not expecting any problems though. Will also weigh that thing

[web]

As expected, it bolts up.

Also looked into the "missing bolthole" on 1G series bellhousings/transmissions. The T-series have an extra transmission to engine bolt hole on the outside of the camshaft housing. A 1G, lacking a camshaft housing, doesn't have that whole section of casting, so 1G bellhousings didn't get that bolt hole.

I know, pics needed. *placeholder*

Toyota clearly thought the remaining bolts were enough even for the 1GGTE, so I don't think there's much point in adding it. Also, the 1G bellhousings have stiffening ribs going to the other four (plus the lower block braces). Even if you add the fifth, the bellhousing would still be designed to send the load to the other four. Trying to fix that is probably more likely to weaken the bellhousing design than strengthen it.

So I'll be happily using the 1G mounting pattern on my T-series - unmodified.

Great work, sort those pics.
