OBD I to OBD II conversion? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

spikevyxel · 10-23-2005, 12:15 AM

Im about ready to buy the Greddy Turbo kit for my 95' 240, however im pretty sure i need to convert my OBD connections. Has anyone done this, or is there a specific kit out there to make this easier. Thanks

Explain your reasoning behind all of this.

evrae205b · 10-23-2005, 12:52 AM

um you dont have to convert to obd2 that would meana you would need all the lil sensors wiring harness and ecu which would be completly pointless. Like stated above explain your reasoning

SimpleS14 · 10-23-2005, 11:07 AM

The reason is because he wants to install the GReddy turbo kit which says its designed for the 96-98 S14 (OBD II). To the original poster, you don't have to convert to OBD II to a make this kit work.

spikevyxel · 10-23-2005, 11:41 AM

Yeah like SimpleS14 said, i want to install the Greddy Turbo Kit in my car. I couldnt see any reason that the Kit wouldnt work, or why they said it wont work other than the OBD stats. Does anyone know why this kit was made for the 96 -98 models and not the 95... and what would i have to do, if anything, to make this kit work for me.
Thanks

There are no differences in the kit, common sense would tell you that. As far as reasoning why they don't include 95, could be the same reason manafacturers sell items from only 91-94 KAs and vice versa, they don't know there were or were not changes and don't know if the application supercedes other years. The hardware part is all identical and if anything it will be easier on a 95 because there's less vacuum issues. The only thing that could possibly come up is clearance to the carbon canister since the 96-98 doesn't have anything in that location under the hood.

Well, I wasnt too worried about the hardware fitting, i was more worried about the software not working right. The kits comes with the Greddy E-manage system, which you have to solder into your ECU. Im not very familiar with OBD I or II so i wasnt quite sure if i would have any problems with soldering the E-manage system into a OBD I car. I appreciate the help.

projectRDM · 10-23-2005, 05:05 PM

EManage suppposedly plugs right in with a socketed harness.

shift_knob · 10-24-2005, 01:19 AM

OBD II does not suck. What the government uses it for makes it suck. There is a lot more to OBD II than the catalyst efficiency monitor.

"If you put an OBD II system on that thing, the computer would keep trying to change everything that you were doing to the engine." - WTF are you talking about?!?!?! Some people don't know their ass hole from a hole in the ground... much less how cars work

Anyway, if you have any doubts, contact the manufacturer and ask. Its possible that the OBD II ECU has a different architecture and the pinout may be different. If the engine management kit comes with a connector specifically designed to mate with the OBD II ECU, you may encounter problems. Just contact the manufacturer and make sure.

I know someone with a Greddy turbo kit and VSPL front mount intercooler.

DIRECT PLUG AND PLAY! Just a PITA installing the manifold. Because the stud barely clears the manifold, you have to work the bolt in there. Other than that installation is cake. Your bumper support wont fit, unless you trim the hell out of it. Also, your car will see stalling issues because there's no bov+recirc.

mistert · 10-25-2005, 05:38 AM

closebyu your thing says youre in japan, there is NO OBDII in japan to my knowledge.

oh yeah and the reason greddy doesnt offer it for the obd1 car is because of the cost of carb certification. getting that carb EO is extremely expensive and because the vast majority of s14's are obd2 compliant, they would end up paying double to test and certify a minority of cars. and (ive been told) that it works just fine there are just a couple of wires left over when installing the emanage on an early s14

The Greddy kit for the OBDII is CARB certified?

last i heard they were still pending?

i could be wrong, though.

Ritz S14 · 10-25-2005, 11:22 AM

Pending. We've called them up, and they said at the end of the year. But meh, I bet they're full of BS.

mistert · 10-25-2005, 05:04 PM

yeah but pending is good enough not to get a costly repair order in california
