3SGTE in 23 Need Help
|

Hi guys, I have been bitten by the HP bug again. I am planning to install an 3SGTE (MR2orGT4)into a fairly good looking RA23.
I need to gather as much information as possible before taking the plunge.
I have read the article on the Targa Tassie RA28, good info, but I need in depth details such as:
1/. What gearbox 2/.What flywheel 3/.What mods to intake/exhaust 4/.What major problems have been experienced by others doing the same conversion.
Any help would be greatly appreciated,
Regards Chuck

OK you're gonna need a W box (e.g. w55, 57, 5 , and then to go grab the bellhousing, engine mounts and sump from an SA63 celica.
The intake manifold sometimes does and sometimes doesn't catch on stuff, depending on how you mount the engine - not sure on this one. Personally I'd fabricate something new there anyway, that put the throttle body in a more favourable place (or even 4 throttles!). You need a new exhaust manifold, as the standard one puts the turbo right over where the engine mount bolts onto the block.
I know theres other problems as well, but till I actually do such a conversion I can't comment much further. Use the latest 3sgte you can get your hands on (st205/215, or later mr2). I'd love to see more RWD 3sgte's though! Just got to be willing to do a bit of stuffing around etc. - I've also *heard* that the steering could be a problem with your car? (not sure about this)

Just a comment on that mrshin, the SA63 sump won't fit on the later model engines as they have the alloy sump that houses the oil filter at the front.
A 'gen2' motor out of an ST185 would be a better starting point as far as ease of fitting is concerned.
Don't forget that the distributor and water outlet at the back of the engine have to go as well. Not sure if you would be able to get the factory ECU to run it without the distributor which would mean aftermarket ECU which would make it very difficult to get engineered in NSW. Not sure what the ACT is like. Go and take a look at an engine at an importers, you'll see some of the hassles that are involved.
Darren.

It is true that the distributor has to be removed but the stock ecu can be made to work!
The water outlet can still be used! I think it just needs to be cut and welded so that it points to the side of the engine!
The bellhousing can be bought from Fraser.co.nz already modded with the starter on the drivers side! It will also be machined to be a bit shorter which is also needed!
I would reccomend the w58 or w57 which has shorter gears!
On the gen 3 i've been told that all you to do is turn the flywheel around and this will work! You dont need to change turn the ring gear!

If you dont know what i'm talking about, dont worry your self!
Turning the flywheel around has something to do with the starter motor engaging! On the 3s normally the starter engages from the gearbox side of the motor!

I am sort up up to speed on this as I am looking inot a 3SGE inot AE86 swap.
As far as i know, you have to swap the ring gear around to line up with the starter, or you make a spacer up to move the starter out a bit, as well as machining 6mm off the bellhousing.
You cannot bolt a flywheel on backwards, it just wont work.
As a note of nterest, a bloke did this swap over here into a Ra28? or something, as well as doing this swap inot his own Hiace Van and did not machine the bellhousing.

Ring the dude at Fraser in NZ! He will tell you everthing you need to know! The flywheel needs to be turned around and the ring gear does'nt need to be turned around! He has done this many times so he would know what hes talking about! The starter will still engage without the machined edge of the ring gear facing the starter!

I am just at a loss as to how you can bolt a flywheel onto the crank backwards (ie machined face towards the block). Can someone explain how they do this?
I know with the 4age flywheel the other side is not even close to flat, so to machine it and get a clutch to bolt to it and actually work would be impossible. Is the rear of the 3S/2S flywheel or what ever one you use flat???

Sorry, Forget everything I have said! The fly wheel I have is off a different type of engine completely! If you speak to the guy in NZ he may tell you about this secret! Then again he may not! This fly wheel has the right bolt holes for the GEN 3 3S-GTE and is also much lighter than the standard item!

Cool 1 (Shane)
By your posts you must be putting a 3SGTE into something & have the right flywheel/bellhousing. I've got a bunch of parts sitting in front of a TA22 & in the process of deciding to go any further with it. The flywheel is my last problem (I hope it is anyway forgetting electronics!)that I'm not sure on, & you're only a few K's away, Aspley? to Brendale. Wondering if I can have a look at where you're at with your car, or if you'd care to see where I'm at.

Chriss, hey buddy, that article on the Targa Tassie RA28 was in "ZOOM" Number 34. Not a great deal of in depth info but enough to get you thinking.
