ok guys. been on here about 10yrs and this is my 3rd time around. I have a built engine from my 1st 1995 that i haven't turbo'd.Had it like 5 years. but bad luck strikes me. This time i couldn't find a clean 1995 in my area or price range so i got a clean 1996. Ok my question is to you turbo guys is. can i run the built engine from my 1995? my goal is 400-450hp on e85 0r 93 pump gas. And what probs am i gonna run into as far as inspections. I live in Nc and we dont do the sniffer test. we just can't have a check eng light on. I deleted all emmissions on my 1995 intake to have a clean look. will i still be able to use that intake? This is my 3rd s14 and i hope my dream can finally come true.

Yeah I don't see why not, especially if your built 95 engine is OBDII. If for whatever reason you DO get CEL lights for crap that you don't care about, you might be able to ship the ECU out to get it "tuned" and remove those codes...
I know my 91 doesn't throw any codes.

Depending on your state, dealing with a CEL in an OBDII car can be very easy...or very hard.

Just because you do or do not have a CEL does not mean you automatically pass or fail. The Emission system reports certain sensors refered to as "Monitors" If you plug a code scanner in, you can check you monitor status. the problem is that certain states have different legislation on which monitors cause an immediate fail. In CT EGR, O2, and EVAP/Gas Tank will cause an instant fail. TO make thing smore confusing, just becasue you dont have a CEL does not mean you will pass. The ECU needs to collect data over various engine conditions before it will report out on each monitor.

What this means is that if you have a CEL and try to pull the neg batter cable off to rest the system to pass....you wont. The system displays a "monitors Not Ready" status...which in CT and a lot of other states is as good as a fail.

Long story short, go to harbor frieght, either online, or an actual store. Buy their OBDII code reader, and see what your actual Monitor status is before you head to the test facility.

For reference, my last "problem car" was a 96 SC300 - OBDII 5 seperate monitors

- EGR Valve
- IAT
- Evap Pressure
- O2 Sensor Bank1 Sensor 1 (Upstream of Cat)
- O2 Sensor Bank 1 Sensor 2 (Downstream of Cat)

I kept failing because of the dam EGR, gave up and sold the car...it just behooves you to know as much as you can before you attempt to pass.

OR, you find a crooked shop.
