Cali Spec?

[futurevr4man]

are there any big differences between fed spec and cali spec vr4's?

i bought my car from california but i dont know if its cali spec or not. i hope the o2 i just ordered wont be incorrect...

Just because the car comes from Cali does NOT make it Cali-spec. My car never spent a day of its life in Cali and it IS Cali-spec.

so then whats the difference and how can you tell? im assuming there is a way to tell off the vin?

[stealthee]

The VIN and the o2's. I'm not 100% sure on the tt's, but I beleive the Fed Spec only has 2 o2's and Cali has 4. There would be differences in lengths of wire.

It says on the emission sticker under the hood if it's Federal or California emissions... What year VR4 are we talking about?

[futurevr4man]

its a 94 vr4. it didnt come with a hood when i bought it lol

Look for the silver vehicle code plate on the driver's side firewall. If the last two digits of the model number are "2D" then its Federal.
If the last two are "7D" its Cali...

[RealMcCoy]

A Cali spec VR4 in that year has four O2 sensors and an EGR temp sensor. The Fed spec has two O2 sensors and no EGR temp sensor. That is the extent of the difference.

oh, alright, thanks mccoy and steve.

i thought there were more significant differences than that

another tell tale sign is the dual port EGR valve, it has a redundancy built in.....lame.
