Has anyone here in Cali smogged their 420A with low compression pistons and passed. Alot (most) people tell me it will pass. A few say it wont. Has anybody had success or know of any shops that will pass you if you pay them off? Thanks

of course but i'm not just going to pick out several people to PM and ask them. It's easier to get it out by posting. If somebody has something then PM.

ok, ok forget the part about which shops there are that will let you pass. Is there anyway to make it pass without swapping motors and just take the turbo off?

My setup (will be) 60 trim turbonetics, Hahn portfueler, JE 8:5:1's, eagle rods, standard bore, stage 2 cams but i'll just swap the head back to stock for the smog. It'll be easier than pulling the whole motor. SO pretty much all i'd have on there during smog would be the low comp pistons and rods. Rods wont make a difference so only pistons that could make any difference. But turbo shouldn't make it turbo any worse since it'll run normal and not add any fuel until you hit boost. So it would run just like taking the turbo off. But might as well leave turbo off after i swap back to stock head huh? Less problems with visual test.

Haha damn it must be hot over there. I'll probably take portfueler off. I doubt they'd no what the hell it is anyway. I could just paint it black and they'd never look twice at it. The portfueler injectors wont work since the manifold pressure will never reach positive since the turbo is off and the factory injectors will still be in their spots so I should be good then.

It just hit me!!! (Must be that great high you get from jet lag) I just got up to Minneapolis and if I'm not mistaken the pistons have a certain temperature at a certain compression that also burns the fuel and if they don't hit that compression ratio (And trust me I'm hoping that you WILL pass because your set up is my role model)the fuel may not burn properly, Right???

Any Moderators or Einstein's wanna chime in on this? I feel like I'm marooned on the moon on this subject and I want this guy to pass so bad with just what he has done so far so I'd learn from his mistakes if any.

What I may end up doing is (and I know many of the guys my think I'm a tad bit crazy) but my thoughts lean toward stock compression ratios but just beefed up parts so come smog time I'd be OK, just a thought.

Yea yea I know tuning would probably be hell but the smog test should be a little to know problem.

Any aftermarket modification that they can see that doesn't have a CARB expent sticker with it will fail you. period.

Do not even think of trying to pass with a turbo kit, visible modifications to the manifold, additional injectors, visible non-stock wiring, or any aftermarket exhaust modifications. You will fail.

Ya i know what you mean. I planned on taking everything visible off but the only thing i am concerned about is the low compression pistons. I'm not sure if they are going to effect the way it burns enough to fail or if it wont make that much of a difference.

That's the beautiful thing about the portfueler. The ECU will be stock even with the 26psi i'll be running. MAP clamp it and the ECU just thinks its running like it did from the factory. The Portfueler is like its own stand alone fuel system. Its got a box about 7 inches long, 4 inches wide and about 1-2 inches thick and its got wires for the four additional injectors, the tach signal adapter so it knows the RPM, a vacuum line that goes into it, power and ground, a serial port to connect to the laptop. It kicks in and adds the fuel when the manifold pressure becomes positive. The ECU doesn't know any different. So i'll just take all the visible shit off and they dont know the difference.

You won't get away with it, as Dino said, anything visible without a CARB sticker and sometimes even the documentation that came with the box = fail. Not only that, but if you fail a visual for illegal modification you have to smog the car at a referee station for life, which means a higher smog bill. Just put it back to stock or as close to as possible.

All that stuff is coming out. All portfueler components will be taken out of the car since i'll have to swap the head back to stock. The head i'll have on there has stage 2 cams, port/polish, oversize valves,ect so that definitely wont pass so i'll put my stock head back on and removing portfueler in the process. The only ECU wiring that needs to be modified is the wiring for the MAP clamp correct? I can make that look stock easily enough. I'll have an EGR block off kit. When the time comes, I'll take the block off kit off and put the EGR back on. Everything visible to the eye will be stock and ready to pass smog. I think that pretty much covers everything. There anything else anyone can think of? Thanks

So has anyone passed with a built engine and made as stock as possible? Haha I'm still trying to smog my car after this many years

I tried it with hicomp pistons before and it wouldn't pass I got locomp now so I'm wondering it will pass. Anyone pass with 1mm oversize valves?

ve passed... built boosted, wit hahn stg 4+. i made some greddy labels, and when they saw those, there were no ?s asked..they only kno 2 look 4 the stickiers and carb #, once they see it, they go about their bizz, it was nice.

You got lucky and found a shop that didn't follow proper procedure.

Normally they will cross check those CARB numbers with the ARB database.

I have seen it pass on low comp pistons with stock injectors.

-K-

no, im smart, used the correct ARB #s for an eclpse greddy kit..

i told him too keep it outa boost, and it blew cleaner in the sniffer test then my N/A did!

i was wondering about that too. I thought it might burn cleaner. Are you in california also?

Well, if you've got a turbo the size of the gst/gsx turbo then it might be hard to keep it out of boost since the spool up at low rpm. My friends gsx when it was stock started building boost at about 2500 but a 16g or 50+trim isn't going to spool at the rpms that they are SUPPOSED TO run the smog test at. I think its like 2500-3000rpm. I'm not perfectly sure. I'd think as long as they keep the rpm where they're supposed to, it would never hit boost on a good size turbo.

my buddy's gst will hit peak boost by 2500 rpm. the awd cars only have to sit in the lot and rev the engine cause the machine only has one drum thing for wheels to ride on. when i lived in cali we would go from shop to shop saying "my car don't run good, how much would it cost to make it pass?" after 3-4 shops a guy would do it for $200.

got that megasquirt!

what size turbo on the gst?

t25

I'm not real familiar with the stock turbo on the gst/x. Isn't the t25 the one they come with or am i wrong?

all factory turbo 2g's had t25's

i thought that was the turbo they came with but wasn't sure. That turbo will of course make full boost at around 2500rpms. It is so small that its air flow efficiency is almost maxed out with stock boost. Another 40hp output, it is already reached max efficiency, same with the stock sidemount intercooler. Probably one of the smallest turbo's to ever come on a fairly modern day car

interestingly enough S13 and S14 Silvias came with a T25 as well

shit, no wonder i never see a stock silvia in my town. Then again there are only about 4 here. But they are rare so i think four in a city this size is quite a few.
