Nikki carb on a 13b
 

Well I posted about my Weber a few days ago but it seems no one knows or wanted to help! No big deal.. I was wandering if anyone has experience running a modified Nikki on a stock port 13b turbo block. The carb is off of a 12a obviously and I know I need an adapter plate, I have a walborough 255 LPH fuel pump and a fuel pressure regulator. Will the stock Nikki jetting supply enough fuel with upping the cfm of the carb? I will be running N/A.

no, you really shouldn't.

weber 45 or 48 would work 10x better

u will not be happy with the power of a carbed, non turbo, t2 engine. compression is lower on the turbo engine than that of an n/a one. and u would have to turn the pressure waaayyy down on that walborough to use it with a nikki carb.

maybe this could be of some help for getting more from the nikki?

No regulator can take 40 pounds down to 4-6 pounds..safely.
You will have to switch the pump to a stock FB unit...or a Holley Blue(or red) with regulator)

I have a 45 dcoe I need some help with tuning it.

Thank you for the help. This turbo swap has been a headache that was mostly my fault for changing my mind 1000000 times during the build. It ultimately leads to me wanting a very simple n/a build. I absolutely love the car and am learning a lot through trial and error. Hopefully in the near future I will have a 6 port to build and to swap in it.

I have a Holley red now!
