RA60 3sge?

[thechuckster]

owen, one of the biggest issues with 3sgte into RWD is the dizzi and coolant outlet at the back of the head. Going waste-spark (which works fine for 4agze and 7mgte) means you can eliminate the dizzi all together. 1J-GTE is effectively waste-spark as it triggers the coils in pairs.

You only need a crank trigger with a missing or extra tooth to provide crank positioning (depending on ECU) to run waste-spark - if that's bolted to the crank pulley then the only thing to worry about at the back of the head is the coolant outlet.

i think an earlier thread discussed oil drainage in 3sgte - remember that rotating the engine puts a RWD gearbox off vertical as well.

rotating the gearbox does cause an issue there, yes, but there may be room for improvement there, as i may have the bellhousing modified to put the starter on the intake side. If I do this, then I will modify the bellhousing such that the motor can remain on its tilt, and the gearbox can remain upright. Problem solved.

Others who have done RWD 3S conversions have reported no problems with oil drainage when mounting the engine upright. I really can't see it being a problem, the oil is still going more or less down!

If you're really concerned though you could drill external drain holes in the head and run a hose down to the sump. Sounds a lot easier than playing silly buggers with bellhousings etc.

Norbs, I would only rotate the bellhousing if i play with it to move the starter... i have a personal dislike to putting starters near exhaust manifolds for some wierd reason (probably because heat is the No1 killer of electrical devices and as an elec engineer, much time is spent finding ways to reduce heat)

Isn't the non-vvti 1JZ sequential ignition?

[RWDboy]

so nobody has mentioned the apparent oil drainage issues that result from the head being upright?

I can't see it being a huge issue, as Norbie says, if there are oil drainage issues then there's always the possibility of adding another oil drain to the sump. With the right oil pump build, sump design and pressure relief there shouldn't be any issues with oil drainage with the engine being upright

What *could* be an issue is possible pockets of air in the head due to the radiator top tank usually being lower than the head itself. But again, there are ways around that too, including a separate (small) high mounted water reservoir with - i think some kind of water/air separator ?

I originally was concerned about oiling issues, but after englarging the sump to 6ltrs or so, I figure there is enough oil to keep everything happy even if some did get stuck in the head and not drain back.

I did tilt the engine around 3 degrees, maybe less, to the inlet side just to assist the drain back of oil. But anymore and it would have caused havoc with the angle of the gearbox and I didn't want to start cutting up bellhousings and rotating them to straighten the box up.

My rwd 3S has seen a few track days and lots of hard driving and never had an oiling problem yet.. Just keep breaking inlet manifolds

[o_man_ra23]

Joel, you ended up just sticking the starter on the exhaust side didnt you?? How is that working out??

Cheers, Owen

[TurboRA28]

Hey mate, nah I used a Y series bellhousing and put the starter on the inlet side. ALso the clutch fork is on the inlet side.. Leaves the exhaust side free for good stuff like turbos and dump pipes

[o_man_ra23]

Y series to W58 bell you say?? might have to talk to vibert about what bellhousing he is intending on supplying with the supra box for me.

Cheers mate... that makes things easy... and 6ltr sump sounds good too, might have to add some wings/baffling/windage etc etc to a 2S sump.

Cheers, Owen

[TurboRA28]

Yeah a 3y/4Y bellhousing from a Tarago or 4runner or something.. Very common and easy to find. They bolt to the W55/7/8 fine. But there is 1 hole that bolts to the block that needs to be elongated.

Yeah I used a 2S as the basis of my sump, cut it up, baffled it, enlarged it.. Dig up my old thread on the conversion I got some pics of it there.

Cheers

Thats on the old forums isnt it?? I think i might do a full writeup in pdf format if anybody wants to have a read once I have finished... ill need to start writing down urls such as your writeup as references.
