Turbo Charger Limitations |
|
|
|
If you are considering a supercharger or turbocharger for
your 22R or 22RE engine, there are a few things you should know. |
|
|
|
The stock compression ratio on an 85-95 22R/RE engine is
9.4:1 and is really too high to truly take advantage of a high boost
blower or turbo kit. You can run a turbo or supercharger on a stock motor
with a factory EFI unit, but you must limit the boost to 4-6 lbs.
The factory computer (22RE/2RZ/3RZ) just does not have
the capacity to retard the timing and add enough fuel to
properly manage a high boost supercharger or
turbocharger. |
|
|
|
A great investment, which will provide you with the right
set-up, is with an LC Pro Fuel Injection Kit. This system will give you
the ability to add more fuel (with larger injectors) and retard the timing
during the high boost operation. It will also allow, with lower
compression, to run up to 15 lbs. of boost with 2 BARS of M.A.P. |
|
|
|
If you truly want to take advantage of a supercharger or
turbocharger, you need to lower the compression ratio to somewhere between
8.0:1 to 8.4:1. That can be achieved with a forged piston replacement,
which will allow you to run higher boost. It is highly recommended to
consider the lower compression and the LC Pro fuel Injection Kit when
adding a turbocharger or supercharger kit to your 22R/22RE/2RZ/3RZ. |
