i got a 90 civic si head with intake manifold,rail and injectors yesterday for free. i know it will bolt up to my 1.5 block. but what wiring will have to be done? is the same as a ZC? and does anyone know about how much horsepower i will from going from dual point to multi? thanx in advance

 

Wow, you got that stuff for free? Nice, nice. Wiring should be the same as a ZC, except that the ZC has one difference.

here is the info, in case you need it.

yeah, the only diff is that the CYP sensor is built into the distrib on the Si, and it's on the exhaust cam with a ZC.

you can reference this info as well:

I just converted my wife's 90 Std. hatch to MPFI using all Si parts and this article worked great for me. No problems.

 

thanks man. i'll look that up. yeah i got it for free. he had two and said i could have one. all it needs is a throttlebody. not to shabby. if i dont keep i'll sell it
