90 Celica St turbo?

[Prophet513]

I am interested in boosting my auto 90 celica st. I have seen corolla turbo kits online for corollas with the same engine and a few ebay turbo kits for the 4afe but I want to know if its been done or if anybody can help me.

And please, don't suggest a swap. I just want to play around with my celica the way it is.

If you're interested in it, look into a few corolla 4AFEs that have been turboed.

No matter what people will suggest a swap solely because of the gains in relation to work involved is much greater with a swap.

Thanks. Also, I've been wondering what is it about a turbo kit that makes the turbo spool and actually force induction.

Like what are the most vital parts to activating the turbo?

Turbos are essentially air pumps .
On one end of the turbo is the turbine wheel. Similar to a jet engine blade configuration, they spin at thousands of revolutions per minute via the hot exhaust gases exiting the engine.
On the other end othe shaft coming from the turbine wheel is a comprssor wheel that sucks air in. It's shape and housing , compress the air entering the turbo and send it tthru an intercooler , thru the intake manifold and into the combustion chamber.
Now because the air was compressed, there is more of it than a normally aspirated engine would have, so more fuel can be added while maintaining the proper air to fuel ratio, thus making more power.
Thats it, in a nutshell.

with my lack of experience its still a little hard to figure out what i need to turbo my celica and what boost level would keep my engine pretty reliable. and if my auto trans can support it all.

i'm surprised this hasnt been done

Which engine does it have?

For turbo'ing a non turbo engine:
Turbo exhaust manifold
Turbo
waste gate
waste gate actuator
down pine
dump pipe
oil line for turbo
oil return line
tap oil pan for return line
coolant line for turbo(if water cooled)
Intercooler piping, couplers and clamps
intercooler
intercooler fan and shroud
Larger injectors
larger capacity fuel pump
fuel pressure regulator
freer flowing exhaust
boost gauge
some type of engine management, eg. -megasquirt, nemisis,etc
forged internals would be better.

The auto trans will probably be good to about 10psi of boost.

my celica has a 4afe, which I am surprised nobody with a celica has done this yet or even a person with a turbo corolla has seen this ha. I'd only even want to boost my celica with like 8 psi
