It is their job to detect any abnormality, includes a non-original engine, yes.

Will every tech catch it? Most likely not. Are they looking for it? Absolutely. The consequences of passing a car that shouldn't is VERY high.

Ehhh. I think you are reaching. A piston n rods engine will look stock. Unless different gaskets were used, nothing is noticeable. Even then, maybe the engine was rebuilt. Is that against smog rules to need to rebuild a motor?

I have been running JRSC CARB kit since several years close to 30K miles now. It is perfect for engine reliability and makes a huge difference in performance. That incremental upgrade to reach 300whp will not make so much difference. I decided to just stay with the CARB kit until I aim 400+ whp.
Yea, i hear you. Youre right if youre going to aim for 400whp, a fully built motor would be perfect. I don't think ill ever go to that kind of power for this car. This is suppose to be a street car still. that why since im going close to 300whp i would like the piece of mind. Thats why i was researching when adding too much boost what would usually break in the engine. This will be a slow process anyways, since i want to learn and do this stuff myself.

I hear alot of good things about the JRSC kits, i just dont want a SC. yes yes yes, i know. If i do, i rather just not boost it. Since im probably going with Works turbo stage 2, if the stock tune is great then ill be happy honestly, that magic 300whp is just a number, once i start driving the car with boost, im sure i wont care as much. my butt dyno might just be enough. Building the motor is for piece of mind. is all.

could i also ask, if youre on the stock tune, what other support mods have you added to support the SC? I would like to know what i need to start getting my car for boost.

Harrop kit, how's that going?
what support mods have you added on?

I have the JR factory tune which is excellent and stock header. And I don't have any other support mods than STI OEM oil cooler and oil catch cans. If you count as support mod, I also have upgraded valve springs (GSC 5756) after the stock springs failed. For turbo, I would go with an air-oil cooler and heat insulation coating for header, exhaust pipes, and turbo itself. And the best tune available. @CSG Mike can help better with all these, he has a very good turbo setup. I would just do what he recommends.

If you add different injectors then perhaps they could be seen if the technician snoops around the injector cover, so you could consider swapping the stock injectors back in on smog day and switching to a CARB tune. If you have an aftermarket tune then they won't know. If you add flex fuel then they will see the lines, so you would have to pull that and put 91 back in on smog day. In theory, you could add a FMIC (if you didn't want the air to water setup) or closed-loop catch cans, and those are CARB exempt.
Closed loop catch cans are exempt?

I have the kit, 700cc injectors, fuel pump, forester xt oil regulator, e85 and flex fuel kit. That is it. 'My build' in my sig has everything.

Yes, although I have read on other forums that they were problematic for people, but like FMIC or catback exhausts, they don't require an EO#. The technician could get squirmish about it and fail someone because someone modified the PCV system, but then again, I believe they would be wrong.

How about dealers, then? Would they be willing to test a CARB certified modification? In NY, I take my JRSC CARB certified FRS to Toyota dealer for state inspection.

I'm only familiar with California law, regarding this. Sorry!

I'd recommend calling dealers anonymously to do some recon.

I was only asking regarding CA. Otherwise, my dealer in NY is just fine with inspecting CARB certified car.

Smog stations will have zero issues inspecting and smog checking CARB legals cars in CA!

So, I would get the carb certified kit for my car. Add supports that will not void carb certification and stick with it, if I were in CA. I did exactly that in NY anyway.

Never heard of a dealer doing smog checks in CA. I don't think people who sell cars can get licensed; conflict of interest.
