CA smog, LA3 and injectors

[notopstang]

I've yet to smog my 84 since I bought it last august(?) since it wasn't totaly complete.. not cat/downpipe, leaks everywhere, blah blah blah.

She's got a 87 Xr motor w/35lb injectors, but the original TE computer. Eventually i want to upgrade the comptuer, but I'm wondering if that will have an impact on smog or anything like that, given the state of red tape in California.

Should I go ahead and upgrade the computer, or look for a set of 30lb injectors just for the inital smog test?

I have all (most?) of the leaks fixed, and she runs well mostly, but I have no idea what she's putting out the tail pipes...

I was guessing it would be rich... I'm just worried about not having the "correct" components in there for the right year.

With my friend's Jeep, it was such a pain when he put in a 94 engine basically into his 86... even though it put out way fewer emmisions.

thanks for the info Mike...didn't know about issues w/the oil.

But my question was more whether or not I would have problems getting my 84 smogged using components out of a later mustang (injectors, ECU, etc). Or should I put off the ECU upgrade for now and use 30lb injectors intead to match the current TE ECU so that I have no issues w/the smog people. I won't go get it smogged until I have a matching set of components, one way or the other....

current: TE + 35lb injectors (running rich)

eventually: LA2/3 + 35lb (any problems getting this past the smog people??)

only if smog is a problem: TE + 30lb (only until it passes smog)

Thanks,

Mike,

I think what he is asking is: Will the emissions of an '86 XR engine with LA3 EEC and 35 lb injectors be more or less the same as the emissions of a stock '84? Are the emission standards the same for all 84-88 EFI 2.3L Turbo engines?

[notopstang]

Does that help?

yes, that's exactly what I wanted to know.

Thanks Mike and Mike!

as long as you match the components (30# with TE, PJ, etc.; and 35# with PE, LA2/3, etc.) then you're guaranteed to pass any/all of the shortened state tests if everything else is functional and the CAT isn't burned out.

What about an early 85 w/o the extra ACT sensor and brand new tuneup stuff and new cat?

BTW, i do have access to my buddys 87 TurboCoupe smog results and specs, maybe we can compare specs to someones early SVO specs for CA emissions and see what to expect as far as how different specs are and such for different ECU/injs. Will post soon or if someone else has them...

How much difference does the lack of an ACT w/the LA3/35lb, etc make for smog and performance? not having to have it right now would make my life alot easier...

I just installed the LA3, but putting in the ACT is more of a hassle at the moment.

If you feel that you really need the ACT signal you can always drop by Radio Shack and wire in a resistor or potentiometer to duplicate the signal between pin 25 and pin 46.

140*= 7.7k ohm
176*= 3.84k ohm
212*= 2.07k ohm
248*= 1.18k ohm

248* is as high as the chart goes so I doubt it's that critical, since under heavy exercise it would be pegged. I'd say set it at 3k to4k as a good range for a light load smog dyno test .
