 3s-gte(st185) into ta-23 conversion

I am about to undertake this conversion within the next few weeks but id like to get a few things right in my head first. I have a st-185 3s-gte and i wanted to know peoples thoughts on this engine and also parts compatability with the st-205 3s-gte's. (ie sump, oil pump, injectors etc.) My second worry is the sump, as I dont want to loose the engine due to oil problems, will i need to get a custom sump made with bafflings in the correct direction??
Lastly, if I use the st-185 / 2s bellhousing / w58 gearbox combo, will I need to modify the bellhousing so the starter is on the other side??
Any help is much appreciated. Thanks
ps. what would be a realistic and reliable hp figure when i run with a custom intake, custom turbo manifold, turbo upgrade, fuel system upgrade and a haltech?

Grab the sump and oil pickup off the 2S cause you will need this!
You dont "have" to modify the bellhousing to have the starter on the drivers side but it does make things easier!

I fitted a ST165 3SGTE into my TA22 a few years ago , The fitting should be much the same only you will have more room in the TA23 ,
The starter on the left side is no problem as you need to make a custom ex manifold anyway , use the sump and pickup off the 2s ,
I just dynoed mine yesterday and put out 241 RWKW @ 22psi boost , in winter it put out 260 kw @ 21 psi
A reliable hp figure dependes on the tuning and the way it's driven .

trevor,
interested as to what size fuel lines you are using and what other engine modifications you have done to get such a good power output( it cant be stock.... you must be running 12's!!!??)
cool1 i gather you are doing a similar conversion yourself, is there anything major (ie problembs) that I will run into??
thanks
gabe

excellent, im VERY interested to know how you go.... does anyone know the fundamental differences between the st205 and the st185??
ive heard better head design, sump and oil pump/filter, basically a stronger engine all round

Differences are far many, but either engine is damn strong.
head design is differnet, valves same size, uses shim under bucket instead of over bucket on 205, intake cam on 205 has higher lift (8.7mm) and longer duration 240vs236, exhaust cam pretty much the same as 185. intake ports are diff size for single runner manifold instead of tvis like the 185. 60mm throttle body on st205, 55mm on st185. metal head gasket on st205. rods, pistons and crank pretty much the same on both. sump different with oil filter located off it on st205, baffling slightly better, little difference really. oil pump i am unsure of. ct20b is a better turbo but cant find parts for it anywhere so people rebuild with ct26a center.
hope that helps.

Jusat curious here ?
is there a guide like that on how to put a 1ggte in a ra23/28 to do the 3sgte to ta/ra celica ?
Would be handy if there is - they are excellent to assist in what to buy for the conversions, since the 3tgte's are becoming a bit hard to come across
Also - trevor - what $$$ figure did it set you back for the conversion ?

A W57 is from an RA60 etc. and is supposed to be similar in strength. It also has a closer fifth gear that isn't as overdriven as the W58.

Yep you need the 2S sump and oil pickup aswell! The 3S normally sits on an angle to the sump is angled too! The 2S sump is nice and flat!

Classique71,
I am doing this conversion at the moment and thought you may like confirmation that everything you're being told is absoloutely correct. There are probably easier conversions you could do but results speak loudly don't they.
My conversion is for Improved Production race car and I will also publish when finished.
cheers !!
