[align=center]Turboing a 1987-1990 2.3 N/A
[/align]
Ok, many of you have been asking how to turbo a 2.3 N/A without swapping engines. Well I'll tell you how to, but keep in mind that I have not attempted this 'yet' (meaning I will in the future)

So, first you have 2 ways to go.

1) Forged Pistons
2) Cast Pistons

1) You replace your current pistons with forged pistons so you can run more boost and feel safer.

Now, you decide if you want to run your stock computer or a turbo computer.

Turbo Computer
Computer (duh!)
Injectors to go with the computer (#30 or #35)
Vam to go with the computer (small - 2.5" large - 3")
Repin your harness

Stock Computer
Injectors (High impediance (sp?) #24 (max 15 PSI) # what ever, the higher the better)
Valve on your BAP sensor (controls the amount of boost that enters)

Once you have decided on what you want to do, time to get to work and make it run!

Basics for doing all of this
- Remove the engine from the car
- Take the engine apart (head, oil pan, etc)
- Take the pistons out (unbolting the main caps and slowly pushing from below)
- Look for any damage to your cylinder head, cylinder walls, crank shaft, etc
- Install new pistons
- Make oil return (tap a hole in the oil pan above the oil)
- Make an oil supply (tap off the oil line by the pressure sensor/sender)
- Put the engine together
- Put the engine back in the engine bay of the car
- Reconnect everything
- Put all the turbo stuff on
- Repin your harness (only if doing the turbo computer)
- Install the bleeding valve on your BAP sensor (only if using stock computer)
- Install your injectors
- Test fire the engine listening for 'ping'
- Make sure your not running lean and every thing is connected before you put any load or boost on the engine
- Start off with very little timing 2* with spout out and knock sensor connected
- get 91 or higher octane gas
- disconnect the knock sensor and play with your timming untill you hear 'pining' then back it off 2* - 4*

All done. Now be careful with the boost on the stock computer. If your running a turbo computer than its just like a 2.3 turbo engine

2) Same as with the forged pistons, only you want to be running a little rich as not to hurt your cast pistons. They will only take 15 PSI MAX and they wont take it for to long before they start to go down hill

It is recomanded that you don't run to long on the cast pistons as they will melt or explode if you lose your tune or run lean, even for only a second
