Hey, I got my B18B, I'm concentrating on building the engine for LSVTEC, but the thought of the ECU keeps bumping my head and I wanna go ahead and see which one I'm looking for.

Looking to setup the LSVTEC with B16 head, B18 block. However, due to upcoming school I'm thinking of just building the bottom end of it and putting it in until I can get the money to buy and build the head. In other words, going in now would be B18B OBD1 into 91 CivOBD0, and later converting to LSVTEC.

So my question is this. For the time the B18B is in there, which wiring harness and ECU should I run?

When I do the LSVTEC swap, can I use the same harness? And I know I'll need to change ECU's, so which ECU should I switch to at that point in time?

Thanks, debating with JDMCars.com's wiring harnesses, but want to figure out which to use and which ECU to use for NOW and THEN.

 

in the first point hopefully your car is multi-port fuel injected

you can use a pr4 ecu for the LS, but when you do the vtec head swap you will have to change the ecu out for a socketed PR3, or if you get an obd1 conversion harness you can get a p28 or something esle

there is no ecu that can function properly for both vtec and non-vtec

 

I was thinking that...would my harness work for both, though?

JDMCars.com offers a conversion for:

OBD0 to OBD1
OBD0 to OBD21
OBD0 to OBD22

Just trying to get headed in the right direction

 

try contacting IH8RICERZ on this website just pm him. He chips a lot of ecu's and i know he does one for ls-vtec pm him hell give you great advice

 

I'll do just that.

Thanks.
