3S-GE project

Ok this is the 3S-GE motor that we want to turbocharge,I have been doing alot of research reading from this forum
http://www.toyotanation.com/showthread.php?threadi d=12190&highlight=5sfe+turbo
I know that the "S" series engines have similar bolt up pattern on the Exhaust manifold, so I have already sourced one of these from an ST205 since the ST202 is from that same year.Here are some of the parts that I am pulling together.
3S-GTE Turbo manifold
3S-GTE Turbo
3S-GTE turbo water lines and oil lines
3S-GTE Injectors
3S-GTE Map Sensor
Supra Fuel pump
Aftermarket Fuel Regulator(boost sensitive)
Custom Front mount Intercooler(air to air)( also intend to spray water mist on the intercooler).
HKS Blow of valve
Autometer boost guage
EGT ( exhaust Gas temperature guage with probe)
Air/Fuel mixture guage
Spark plugs
If there is anything that I need?
Also how much boost do you recommend I should run on the engine?
what is the compression ratio like on those 3S-GE?
what is the stock horsepower and at how much RPM is this achieved?

Im pretty sure ur gonna need lower comp pistons as well - dont ask me whats best tho, but i guess if u want to run reaonable to high levels of boost, forged type. Also i guess stronger rods then?

that's a gen3 - best basis for the project. factory lower c/r pistons are available - you'll need them as this motor is around 11:1!!

I have gotten quite a bit of information from Toyota Nation.com,where guys have been discussing turbocharging the 5S-FE that goes to the states and running boost between 5&8psi. To run more boost then we will invest in a set of Forged pistons and a CT26 from a 7M-GTE, some 2JZ-GE injectors and a fuel pump. The owner of the car doesn't want to part with his 3S-GE. Has a very low mileage (64000km).From reading some of the other post in this forum and other forums I also read of a water injection system made from using a fuel pump,cold start injector and a window washer reservoir and plumping it into the piping between the intercooler and the piping. Need to get more info on that and what are the benefits and disadvantages of doing that kind of setup.
I also heard the stock 3S-GE map sensor is no good for boost so installing the 3S-GTE map sensor will be a good idea.

youd be better off buying a 3sgte - but if you must go to all this hassle of making one yourself - just remeber you wont be able to run alot of boost - the pistons will shit themselves pretty quick at that compression ratio ..
you REALLY should see if you can get a gen3 3sgte motor from a turbo MR2 - and use that as your basis ..
That motor Stock - will handle 15 psi plus withiut a hint of struggle or fuss , though your gearbox wont handle this power for very long without upgrading it - and the clutch as well
youd want the 2jzgTe ones too - if you want larger injectors .. though , once again - a gen3 3sgte has these already - 540cc denso units
The ct20B is a better turbo to use for most applications - which also comes with the gen3 3sgte motor ..
gen3 motor also has better head design , better inlet design , and alot of other goodies ..
ERL would be a recommended system for water injection - youll need this and a decent intercooler setup ( ironically once again ! the gen3 3sgte comes with an excellent water to air intercooler - if you get it from a gt4 ) unless you want to face detonation issues
