datO))) Posted March 14, 2017 Report Share Posted March 14, 2017 I have searched and searched for information on how to modify a stock a 12 carburetor to except blow through turbo. There's a lot of information that is all very similar but when it gets down to specific modifications to carb , it is vague . Is there a detailed thread regarding blow through turbos on A motors ? Specifically modifications to carbs including parts part numbers ? Do you have to modify a carb if you build a full enclosure around it ? Do you have to modify the carb if you use a top hat ? The turbo I'm using is off of a 650 Yamaha seca bike. Quote Link to comment

datO))) Posted March 15, 2017 Author Report Share Posted March 15, 2017 I guess I'm just gonna try boxing the whole thing in it makes the most sense to pressurize everything as one and just monitor the tune. Where just hope I don't lean it out and fry the thing Quote Link to comment
Morrisun Posted March 16, 2017 Report Share Posted March 16, 2017 You may have already looked into the basics, this:https://www.youtube.com/watch?v=q4h69sTB2Dk is an example of what you are looking for only a bit larger engine, a 280Z, but has good explanation of the components used and why. Perhaps this may help?? Quote Link to comment
Mattndew76 Posted March 16, 2017 Report Share Posted March 16, 2017 Wow that guy really doesn't understand why a pop valve is needed at all. All of his electronics are not even secure...... HALF ASS. 1 Quote Link to comment
docbainey Posted March 16, 2017 Report Share Posted March 16, 2017 If you box and pressurize the whole carb, you'll still need to increase fuel pressure proportionately to boost. 2 Quote Link to comment

Mattndew76 Posted March 20, 2017 Report Share Posted March 20, 2017 Your A motor isnt any good? Quote Link to comment
datO))) Posted March 20, 2017 Author Report Share Posted March 20, 2017 It leaks oil, gutless, . It's left me stranded a few times now. I'm going build the R16 To drop in. Then build the A12 up as a spare or to sell . When I bought the wagon, it had issues. Fixing my DD is tapping out my wallet And it's hard to buy anything anymore for the wagon knowing that a It was a hack job. Haven't taken apart the A12 so it's always a gamble. That was a bit winded lol but that's just proof of my stress with having a hobby Like this . Quote Link to comment
datO))) Posted March 20, 2017 Author Report Share Posted March 20, 2017 Swapping out the A might give me a chance to build it and set the turbo up And answer some questions we all may have . Just a bit of positivity. Quote Link to comment
