supercharging 22RE?

[turnandburnae86]

i recently bought a 1984 celica GT-S with the 22RE. I want to supercharge it. from what i have read i need to lower the compression to around 8.0:1 and then i would be able to run close to 15psi...

I know a fair amount about cars i have been working on toyota's now for about 4 years. I will admit that i dont know much about tearing into an engine tho. I know how they work in theory, and i think that i would have no problem tearing apart a motor and rebuilding it. the fact of the matter is that, i just have not done it yet...

question 1.

what are some things i can do to lower the compression (forged pistons, fuel injectors, crank)? what about the top end?

question 2.

seems that all i can find on the internet about supercharging a 22re is for the trucks. i realize that they have the same motor, but they have been using this motor for a very long time. are there any differences that will cause problems with install? or are there going to be different superchargers, etc.

question 3.

where can i find a good + cheap supercharger?


any advice or literature (links) would be geatly appreciated!

I'm not an expert on supercharging, so take this with a grain of salt.
The trucks had the turbo 22R-TE as an option (notice the T in the engine code).
This was slightly stronger than the standard 22R-E but I don't know in what way (wasn't sold here in Australia).
I think it also had stronger pistons.
So it makes a good base for a supercharged 22R engine.

Anything you do to supercharge a truck 22R will be exactly the same for your Celica.

How much experience do you have? Because you will end up either making the parts to mount a supercharger to a 22re yourself or paying to have them fabricated (and paying a lot!!)

The 22rte is an excellent engine, and swapping over to one will end up being cheaper in the long run. Unless you really, really want a supercharger a turbocharger will get you the additional power and if its responsiveness over power you want they can do that too. The biggest advantage the 22r-te has is that is COMES with a turbocharger, so you can swap one in and have the car running sooner than supercharging a 22re.

If you are dead set on supercharging a 22re then you need to look at what supercharger you want to use, the M45 makes a nice gain but if you want to run more than 260 horsepower you will find it lacking, another option is the eaton M62 which comes on the SS supercharged Cobalt. It's a great supercharger but is expensive for a nice reliable unit (cheap if you want to rebuild one.)

The problem with superchargers is they are not "lag free" like a lot of people think they are, the boost lag depends on how well your engine flows. If your stock cam restricts the airflow of the supercharger (the restriction creates the boost) it will stop flowing as much air and just heat the air up until the engine moves it into the cylinders, whereas a turbocharger makes boost right out of the compressor housing. Hot air tends to cause fuel to detonate more readily and will cause chipped pistons pretty quick so be ready to tune for a lot of fuel or set up for water injection. Both of which require more time and money.

▲Um, what he said, beat me to it!

The 22RTE has a different cylinder head (don't ask me how, all I know is that it's different and hard to find), forged pistons, and the block is drilled and tapped for the oil lines to and from the turbo.
Keep in mind that the '84 EFI is different than the post-'84, so your engine is really an early style 22R with fuel injection, and that engine was never turbocharged. BUT...a later "RE" engine will be a direct bolt-in for your car, but you will need a different EFI system to run it unless you use carbs on the supercharger, like weber 38's.

hmm.. so those camden superchargers are illegal in california? damn! lol.

I understand what you are saying. there is a lot of work that i am going to put into this motor, i have not figured it all out yet. i certainly do not plan on going out and slapping a supercharger on it and calling it good. supercharging it is way WAY down the road i am just trying to plan it all out and see what i am up agianst. thank you for your advice on the 22ret, but i want to do something different. something you dont see everyday... thats just me. plus everyone is all about turbo charging these days... what happened to the superchargers. its all those damn magazines screwing up kids heads these days!
