So ive read before that you can turn the m44 1.9 into a 2.1 or even a 2.3? I just have a few questions. 1.)Say you modified from a stock engine with no upgrades, is the stock ecu still compatible or do you need to do something with tuning? 2.)can you still do the 2.1 conv or 2.3 conv, if you have the DASC? So basically is the dasc compatible with the engine upgrade? Would you again have to do something with the ecu/tuning? 3.)What exactly do you have change (what parts) from the engine to make that 2.1 and/or 2.3 upgrade and to start at 0 miles. Would the engine be heavier or slightly heavier? 4.) So the stock 1.9 is 138 hp at the crank, what would the hp be at 2.1 to the crank and 2.3 at the crank. 5.)What kind or where can i get the parts that will be needed for the upgrade? Is there a website? So how much would we be looking at in the parts for doing the upgrade. 6.) When done with the conversion, can you run more than 10psi of boost? Thanks for help. Im sure this will be benificial for other people as well. | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
