ED VTEC Conversion - Keepin the Carby
Hi Guys,
I've had a search around, not only here, but other forums, but haven't been able to find much help.
My poor old ED6's D15B4 is leaking a shitload of oil and blows a whole bucketload of smoke. I'm thinking it's time to get that old motor out and slot in a nice D16Y1 VTEC motor. The thing is, I'm quite keen on the idea of keeping it carby. I've found a weber manifold in the US and will most likely be running some Twin 40s on it before too long, but first things first, I need to get the motor in.
The first thing that I'm wondering is, do I need to get a loom with the motor if I'm not worried about the ECU being able to run the motor. The loom is only to connect the engine to the ECU correct? And if my car runs fine without the ECU (which i've tested by pulling the ECU fuse and driving the car for a week) then theoretically I don't even need the loom correct? (I'll sort out something for VTEC engagement later, most likely a VTEC controller or a re-engineered shift light kit from Jaycar)
My second question is, can I just re-use my D15B4 dizzy (vacuum advance) on the D16Y1?
Thirdly, I can't think of anything else I'd need to change other than sorting out a fuel pump (I'm probably going to go with an electronic one in the engine bay) and some sort of VTEC engagement. The D15 Carby manifold should bolt on fine for now, and so should the exhaust manifold I have. Any one else who can think of something that I'm not thinking of would be a massive help to me here.
I really appreciate any help anyone is willing to offer me on this, and once it's done I'm happy to take people for a ride in my carby VTEC... :P
Thanks guys
