Unless the EF is an Si, I believe you need to do a DPFI to MPFI Conversion in order to do the B18A1 Swap. Don't quote me on that though, I'm not too savvy when it comes to EFs.

BTW, welcome to the site!

Your right about that dual point to multi point injection i swapped all the wiring and computer to solve that problem, im hoping thats all ineed to do to solve that one?! but im having a problem with interior wiring not all the connections match what would you suggest is the best way to go about getting the wires hooked up splice connector clips or is there a different way? and ive also been looking into doing a vtec/1.6L head swap? suggestions and advice please!

I believe you also need to swap the Interior Dash Harness in order to complete the DPFI to MPFI Conversion. Then and only then will the plugs match up and you'll be good to go.

As for an LSVTEC (B16 or GSR Head on the B18A1 Block), there are many write ups on how to do it properly online. However, I say you first solve you wiring issue and get the car running right with the stock B18A1 and then worry about doing the LSVTEC.

For sure and the interrior wiring is also tegra wiring so all i need now is to hook the injectors up and finish putting the head and a few minor parts on, as far as motor upgrades what would you do first stick to non vtec, turbo with built bottom end or all motor?
