Hello,

You mentioned a few times this was going to be a CARB 50 state legal emissions swap. Can you tell me how you did that? Here in Colorado if you are going to do an engine swap the engine going in has to be the same age or newer than the car. The metro area or basically the front range of CO follows CA emission laws. To my knowledge most other large metro areas follow suit. If I take a car with a swapped engine the first thing they do is drive it into the emissions building turn it off and turn it back on and if the check engine light stays on you are toast - flat out. New law went into effect last year. Then they plug into the ODB2 port to see what codes are on. They will also discover that the ECU is for a Chevy and you drove in with a NISSAN. I guarantee that will raise some eyebrows. So help me out here?

Thanks!!!

The slave cylinder fails and causing all of this?! lol I thought I was nuts.

The entire key to getting it CARB'ed is to buy the EROD kit. Its the only 50 state legal swap that i'm aware of. The cams and headers on this make it no longer CARB legal so for inspection I need to swap on the OEM GM headers and cats back on for my inspection.

The motor and ECU setup come with a CARB EO exemption number which I bring with me at every inspection.

The only thing the CARB ref got me on after initial install was my fuel setup since I ran an aftermarket FPR, I had to run a C5 corvette FPR for inspection and approval.

Well when you have a crate motor and a transmission sitting in your workshop, it gives you options...

This might work in some states but not where I live. I took this from the first sentence of the D-126-30 carb cert. If your car is a 2008 one needs to put in a 2008 of newer engine.

"The LS3-6.2L V8 E-ROD Kit is a complete engine and emission control package designed to change engines from all 1995 and older passenger cars and light duty truck 1." (ODB1 cars) They (Chevy) may say it's ODB2 compliant but not to CARB.

Summit fails to tell a buyer this important fact! nowhere in the description about pre 1995 vehicles only. If I'm wrong please let me know!!!! I would hate to spend 20-30k only to find out it can't be registered.

Chevrolet Performance has worked closely with the California Air Resources Board (CARB) to secure emissions approval for these high-horsepower, high performance engines. These Chevrolet Performance LS3 6.2L E-Rod crate engines are the first crate engines of their kind to be certified 50-state emissions compliant. With their stunning combination of horsepower and efficiency, these Chevrolet Performance LS3 E-Rod crate engines are perfect for the race track or just cruising around town in your street rod or musclecar.

Features include:

* 6.2L LS3 engine with 430 hp and 425 ft.-lbs. of torque
* Engine wiring harness
* Engine control module with emissions-legal calibration
* Catalytic converters
* Exhaust manifolds
* Oxygen sensors and sensor bosses
* Fuel tank evaporative emissions canister
* Air filter
* MAF sensor
* Accelerator pedal
* Instruction manual

Well, my California Smog ref didn't see or just didn't comment on it when he certified the original build. Hypothetically i could just leave the OEM Z33 ecu and OBD2 connector in for smog purposes. Or even use a GM tech 2 software to match the vin in the ecu to the car.

The Emission Police just don't like us. My friend and wife own a Prius and even they now have to take their car in for emissions...Good grief the engine shut off at a traffic light.

I do like your build a lot and enjoy following the build.

Ah I got yah. I know where there is a brand new LS9 sitting around if you get bored. I think my slave cylinder may fail.

How's you wing r&d going?

It was put on temporary delay while I waited for a working vacuum pup to arrive. The first one was DOA and it took forever to get through a lengthy warranty process.

That being said, I just got the replacement pump in about 5 hours ago so its on! The plug is already complete so I need to make a mold and then put it into actual use.

I've been keeping myself busy with getting a better intake setup that ended up with me making a new crash structure(bash bar) and support for the future splitter.

Mock up of the corvette radiator and intake:


Halfway done


Radiator and intake fitment complete, all support welded minus the supports going to the subframe.



I ran out of aluminum stock so this week I will have to go pick more up to make the radiator shroud and bumper to radiator ducting.

90nissanS13

Sweet, looking good. It might almost get mistaken for a drift car as it sits now.

I'm looking forward to seeing the wing as you continue. I'll be patient considering you are manufacturing it as proper as can be. I'm still a little dumbfounded to see a Nismo going through such a make over. Good thing is that I'm not a purist, I can accept it and enjoy it. My 240sx is getting the same treatment.

I know it looks drifty... I promise its not the end state! It should start looking a lot less drifty soon.

Well, when I tore the rotary out of my FD, the rotards flipped their ****. The Z crowd is way more tame compared to them.

The motor isn't what makes the Nismo Z special, its the chassis. that's why I bought it. Plus to be honest, I'm not driven by what other people think I should do, that's the path to mediocrity.

90nissanS13

Oh, I know it will be under the skin of the car. I just had to poke fun at the car.

Well, I guess it's not an RX without it's wankel. They aren't known for their chassis.

That brings up a good point, as you are probably more familiar with the Nismo chassis than most. Is there anything that stands out as enhanced from what might not be on the other Z33 chassis? I realize most of the R&D was in Aero but, I read all the time about the "chassis improvements". For the 370z, you can literally go out an buy the chassis brace package used for the Nismo. I would really like to know where the chassis difference are.

Are they subtle changes and big obvious braces?...

Between my 05 Z and the Nismo, there is additional reinforcement by way of the Yamaha dampers. I've also noticed some seam welding on structural panels as well. You really wouldn't see the seam welds unless you tore the car down and honestly a lot is covered by adhesive as well. I'm sure there is a lot more obvious welds under the carpeting but since that has to stay in for now I won't find it until I return back to the USA and switch racing classes.

I am digging the new bash bar, is it worth it to fit a corvette style intake? And as long as you are making it, why not angle the radiator?

armt350z

iTrader: (6)

I think it is worth it, The MAF placement on the previous intake was poor at best. It also had a problem with high IAT's and after a bit on track it would get high enough to start pulling timing. If I can get temperatures down to 20 degrees above ambient I would call it a win. Right now I'm seeing temperatures 70 degrees or more above ambient at times. assuming a 430 BHP (not accurate), a 50 degree change in IAT's would be around a 22 HP difference.

You can't really see it, but the radiator is sitting with the top 14 degrees rearward. I may try and redesign that later to get a forward tilt to make ducting easier.

I know on the samburg radiator setup for the FD that IAT's are higher idling, but while moving it does show improvement. I think you should stick with the rear angle and duct it and call it good. Do you have vents in your hood?

armt350z

iTrader: (6)

I haven't made those yet, I'm spacing the rear of the hood until I can get the ducting and vents made.

Justin's design worked well moving but if he had added one additional piece of metal, it would have solved the high IAT at idle.

Classy

iTrader: (7)

Which piece?

armt350z

iTrader: (6)

If he had put an air diversion panel between the filter and the radiator core, I'm willing to be it would have significantly lowered idle temps up until the entire piece was heat soaked.
