I recently upgraded the turbo on a 4 cylinder Ford car.. The install of the turbo was pretty easy.. everything is tight, but with a little thought, it all goes together rather simply...

The problem I'm having is upgrading the computer.. We installed one of those MegaSquirt aftermarket computers and cant seem to make heads or tails of the timing and fuel..

So my recommendation to you Phil, is to get the computer upgrades all set before you start wrenchin on the Neon..
