Using Mitsubishi's Plentyfull 14b Turbos on Honda

We recently had a questioned asked on Facbook. We though it would be helful information for an interesting home brewed Turbo set up for the Honda guys so we posted it here, in the DIY forum. Below is the copy and paste from the email...

Do you know of a good engine set up for a 1998 civic i want to eventually turbo it?

Actually I do know a low budget turbo set up that works for a NA Honda. I'm assuming your looking for a low budget, maybe do it yourself set up. Otherwise you could just go out a drop $3500 on a Greddy or Edlebrock system and be done with it, lol.

The important thing to know when adding Turbo, or super charger to any Normally Aspirated engine is to keep the boost levels low, its cheaper then lowering compression. Unfortunately, unless your willing to run race fuel. Forced induction and high compression does not mix well. So understanding you wont be pushing that much boost (more then 6lbs is risky), you don't need a big turbo set up. Mitsubishi used the 14b on many cars and most who own them go with the 16G (the larger one) and boost 19 to 20 psi. They can run this much boost because the engine was built around forced induction and therefore runs a lower compression. Now the Honda guys should be jumping allover the 14B's because the Mitsubishi guys sell em off cheap and rebuild kits are plenty full. The last 14b I purchase, I got used off eBay for $150, spent $50 on s rebuild kit and 3 hours labor, rebuilt the turbo. While it was off, I had it ported on the exhaust side. Ran 15psi on it for almost 2 years. Was still boosting until I got a deal on a 16G I couldn't refuse (freebie, Lol). From what I understand the rebuild kits are a little more expensive now, but still cheaper then a new set up.

You will need an AFC controller to richen the mixture to accommodate the additional air flow and step the injectors up as well. But those mods are external and pretty simple. You have to get creative with your piping and manifold, but if you understand how a turbo works, it should be pretty easy. Would take some work retrofitting this hybrid style turbo set up. But with $200 - $300 in Turbo parts and some elbow grease you could have a pretty cool turbo set up boosting 6psi and spooling up fast. Street Honda's should run a small turbo anyway. You want the quick spooling for bottom end on the street.

You can get most of the parts you need on eBay, get creative when routing your piping and your good. Otherwise just drop $3500 on the Greddy/Edlebrock set up, $1500 on the install and fight the urge to bypass the boost controllers 5psi setting and turn it up to 15 like the Mitsubishi guys.

Not sure if that answered your question but, now you have more info on boosting your Honda.
