I recently upgraded to the 2056 engine. I opted to use Empi 44s which I believe have 135 main jets. The problem I'm having is that in 3-5 gears, at about 4200 rpm, the engine just doesn't want to accelerate any more. I've been told to put bigger main jets in and that that should help.
I'm just wondering if anyone here has any input, and also what others are doing with the 2056. Thanks Nate |

I think 44's are a little big for that T4 combo. VW T1 guys run them all the time but the engines react different. Most T4 guys run smaller venturis when running 44's to keep the velocity higher. Smaller venturis make the most benefit at low rpm. If you are running out of fuel at higher rpm, it may be a combination of things. Jet size and fuel pressure along with fuel volume are some things to consider.
