I dunno, if you can get 4AGE forgings cheaper I'd go that route. Stout little iron blocks, inexpensive, robust. A 12 isn't terribly hard to crack in a 2000 lb car, it takes less than 200 whp and decent traction.

Agreed, from what I've heard the 3s-gte is fairly heavy...not to mention the parts for the 205's 3s are failry hard to come by...

meh heavy dont matter keeps the power down. and as far as a 205 engine being rare. internals are the same as all other 3sgtes. the 3sgte is one of the best 4clys out there and i want a rwd version

spraying nitrous into the turbo will cause the fins to bend and unbalance the turbo

yea I had conveiniently neglected to think about the thermal properties of N2O at that pressure, thanks though :P

Oh, I was referring to all the other bits on the engine , not just the internals...and you don't have to tell me the 3s is a good engine, it's discussed on my Celica forum constantly....it's a little heavy yea, but it's got a nuke -proof block (for a four cylinder) can make good power with just a turbo swap...it's even still used in the super gt Celicas ...as for having a RWD version, it shouldn't be that hard, people make "half-tracks' out of Celica all tracs all the time....try visiting alltrac.net

Turbos create torque, the displacement difference between 4A and 3S is meaningless in an AE86. Also, 3S-GTE has super tiny exhaust ports, stock for stock the 4AGE head will take you further before bottlenecking.

Got news for ya buddy, the 3S-GTE (even ST205) isnt that great of a motor. Yeah yeah alltrac.net mr2 3rd gen blah blah ct20 blah blah small port piece of rod bearing spinning, head gasket blowing junk. You are right about the st205 being the best 3s. It is by far. But it is STILL far inferior to the honda B-series and the 4G63. In my own opinion (and personal experience, having owned quite a few toyotas, mr2s among them) the 4A-GE is a far better engine to turbocharge and make power from. Parts are cheap, and it already sits in your corolla. It is the easyest n/a engine on the planet to turbocharge. You can even use the stock manifold.

100% correct.

If you only want 300 hp why go thru all the effort to stuff the 3s/w55 into a corolla YOu can make that on your 4age with nothing more than an afc and dsm 450cc injectors (yes they fall right in) Plus, you will have to consider that if you set the 3s right side up you will need to redo your oil pickup, as it will no longer be submerged.

If your dead set on an engine swap, grab a 2rz and tranny from a 2wd taco, and go to town, as they will handle 400hp all day long on the stock longblock.


Before you retort, Yes the 3s does infact suck a dick. But not as bad as an sr20
