How much tuning? 2056 D-Jet. Options

[MikeM]

Hi all...For you 2056 guys out there...how much tuning is involved after building the 2.0 liter to 2056 and keeping D-Jet? Keeping stock cam as well. Does the MPS need calibration and adjustment? Maybe just stick to 94mm?
Thanks,
Mike

I have done this and agree with Rob on the process. But adjusting the stock system is a pain in the ass.

A couple of suggestions.

Change the cam. Even if you just change to the updated FI compatible cam you will be happier and get more out of your 2056 build.

Be sure you check you deck height and adjust shims to get the compression you want. http://www.cbperformance.com/v/enginecalc.html I did a build and had way less compression than I wanted due to incorrect deck height.

Also confirm your valve train geometry as you may need to make adjustments.

Consider using a modern FI system like Micro Squirt. Full disclosure it is a pain as well but you can actually do a lot more tuning wise with it and the relative simplicity of the system is way better than stock.

Next get the best P/Cs you can afford. AA makes some perfectly fine P/Cs but if you can go with Male or better yet Nickies from the Type 4 store you will not regret spending the money.

(IMG:style_emoticons/default/agree.gif) If you're willing to split the case and go that far into the rabbit hole. I'm actually doing that now - building a 2056 with FI-compatible cam to replace my current one that still has the stock cam.

If you don't want to go that far, the simple 96 mm P&C upgrade is fun too.

I'm not interested in splitting the case unless absolutely necessary. I'm worried about a bunch of tweeking to the DJET. The car is an LE so I don't want to change too much. It's down on power because it has BUS pistons and cylinders. Other than that it runs perfectly. Maybe sticking to 94mm is the best option. I have another car with a carbed 2.4 so not looking for tons of power.
