whats the deal with the 4g63? is the evo's engine so much better than our gt-four's engine? they're both 2.0, 4-cyl, single turbo, how are the mechanics of the internal? does the 4g have better internals for more output or what?

Like if there was a 4g swapped lancer and a 3s swapped gt/st, what do you think the results will be?

the reason i ask is, i know a evo owner and adding simple things to his 4g adds so much ps and it frightens me... with a street tune up, evo mr turbo or some sort of turbo upgrade, and exhaust, along with other minor things and he's hitting 450ps. us 6gc'ers with the 3s swap is working hard and going through so much trouble and still only hitting little over 300ps.... Is the 4g that much better? i feel great jealousy... i want to cry a little... frown.gif

does anyone know the stock psi of the 4G in the 8 compared to the 3S in the 205? could this be something i should take into consideration?

4G63 has been updated many times. The 3SGTE hasn't been updated in years. Technology has alot to do with engines now and how much power they make.

The 3SGTE is dead with updates, just like the 2JZGTE, 7MGTE, 1GGTE, and many performance oriented engines.. Why would Toyota update an engine they will not produce in their line up cars?

No idea what the stock psi for a MR2 Turbo, but it starts blowing hot air at 17psi from my memory...

the 4G63 is pushing much more than that..

the 4g63 is one fine piece of machine work. it is a nice solid block that can take a real beating. pretty much bullet proof, its been able to be put under a lot of boost stress as well as time. my friend has a 4g evo n he puts it through hell and he has stock internals with an upgraded turbo n its still running strong.

There is nothing about the 4g63 thats all that much better. The main difference comes from the fact that the 4g63's always came with a much bigger turbo then the stock ct26. Go upgrade the turbo on the 3s and you'll have a whole new car.

The EVO also gives you the ability to reflash the stock ecu, and change the fuel/timing maps to anything you want. Thats a big bouns over the 1990s 3sgte technology.

Different story. Toyota ECU's are about unbreakable where Honda/Mitsi and other Jap cars can be fine tuned without using a standalone ECU.

The latest 4g63 runs 18psi stock.. the 3rd gen 3sgte runs.. uh i think 12?

4G owners can push a LOT more boost on stock setup.. the 4G is made like the 1/2JZGTE.. it's hella strong. However a lot of these ****tards think it's BULLETPROOF and it's not and they blow them up.. and I laugh hardily.

The engines themselves are actually extremely similar in design.. so the only real difference is that the 4G is stronger and like it has been said before, has many many updates to external parts such as intake manifold/exhaust **** like that and also the engine controls/ecu.

I'd still take a 3rd or 4th gen 3sgte over a new 4G any day.

In stock form, the head from the 4g flows more too.

i know your trying to do the right thing for your motor, but this is one of those times where you should just trust the guys who have had their swaps for a while and have done a ton of research into this.

As far as I know, turbos blow nothing but hot air...this is why we have intercoolers.

anyone ever thought about putting the 4g in the celi? kindasad.gif i know most of you don't like the idea of cross branding engines but what would that engine bring in a gt-four? or do you think the 3s is the only engine that has the right to be in the gt-four's engine bay?

the evo 9's run 21psi stock, not 18.

evo 8's get up to 20psi

tuned with a turbo back exhaust, its safe to run both the 8's and 9's at 22-23psi on california 91 octane

i havent seen the internals of a 3sgte in person, but i took apart an evo8 engine last night. the block is of good design, and the main caps are incorporated into a girdle for the bottom of the block. many people add similar girdles to their engines(v8 engines from my experience) to improve strength. evo's 4g63 already has that. the rods looked like a strong design. the ring lands on the stock pistons were also big, huge in comparison to subaru engines. the cylinder head is also very well designed with smooth flowing ports.

but it has been said earlier in the thread. the main reason why evo's react so well to simple mods is the turbo, its pretty damn big for a stock turbo.

I thought toyota still makes and puts on 3sgte's in thing like the caldina or whatever its call, and even if a few other cars. or just stopped making them a few years back.
