Well after spending lots of $$$ and seeing lots of work coming up, I hope to finally have my car to a respectable point. Should have a decent 2.3 with TBI and Microsquirt. Koni adjustable on all 4 corners. Front and rear anti sway bars. Rear coil overs and 180lb springs. New rotors, wheel bearings front and rear. All new bushings. Adjustable drop links on the front. DIY Autotune hotspark ignition. And lots of 914 rubber goodies.
This is going to be a lot of work! Will try to document it as it progresses. |

Do you have all 4 ITB vacuum port connected to a little manifold to a single line to the MPS? I thought I had read something about this kind of setup from Mark Henry, not sure though...

Do you have all 4 ITB vacuum port connected to a little manifold to a single line to the MPS? I thought I had read something about this kind of setup from Mark Henry, not sure though... (IMG:style_emoticons/default/popcorn[1].gif) Each of the ITBs are joined together by a vacuum port on each of the sides of the engine. So these two ports are joined together and go directly to the MAP. After looking over the cam specs (410 value lift and 278 duration) I think I am going to get a poor vacuum signal regardless. Pulled off the manifolds and checked for vacuum leaks and really did not find anything. Did a quick test to run it on Alpha-N rather than speed density and got much better results. Doing some testing to see if I can get it to draw a bit more vacuum. Increasing advance at idle to increase RPMs and then will close of the throttle bodies more to reduce the idle to where it should be. Should help some. But I think that. I will have to run a hybrid of Alpha-N at low speeds and the switch over to speed density at higher RPMs. Developed a couple of different Tunes to see what works. |
