Default cali leagal FI or shortblock

ok ive done many searches, but i havent found exactly what i'm looking for. my goal is 400-450 rwhp on my 98 z28. if i had my choice, i would have already gone FI. the problem is, my car has over 130k on it and i'm not about to stress it. so heres my question. do you think i could get a new shortblock and mild H/C to pass cali emmisions, or should i just use a procharger P1 or sts (if they ever get a CARB exemption) and a cheaper shortblock or rebult block? i dont want to spend over about 5-6k. now i'm not even sure if i'm going to do this. the thing is i have to get a new engine anyway as i'm planing on road racing in the near future and i'm not comfortable racing on my engine as it is right now. the FI option as i see it is alot more expensive, so i need your guys opinions. should i go FI or should a mild H/C be more than enough for my application?

Ya but if he is making 400-450 on heads cam it DEFINATLY aint gonna be smog legal. That said i havent a clua what is smog legal. Area any of the supers?

What i do to get around emissions here in CT, which have the same laws as Cali, Is jsut unregister the car when they say I have to get it emission tested and immeaditly reregister it and the whole process starts over again. It takes them forever to get you the stuff saying that you have to do emissions. Well over a year. So it costs me 90 dollars to reregister adn im set. GL man

I really dont see how it would be. Obviuosly they aint gonna know the heads and cam have been changed but they definatly are gonna hear them. You might be able to get real close to the 400 hp make wit ha smog legal cam. My bud put a GM hot cam in his 99 nad with headers y-pipe cat back, lid filter ported tb and maf ends tune pullies fast toys ram air, camaro not ws6, smooth bellow he made 364 to the wheels after the tune. With good heads i think that 400 would be possible but i dont know if it would be legal. Ya start movin alot more air and fuel wit hgood heads. GL man

Ed blown Vert is making well over 500rwhp supercharged with a cam and is smog legal in CA,so i cant see how if he does it right it wouldnt pass.a cutout will save you quite a bit of hassle.get an electronic 1 or do dual cutouts,when they test keep it closed and leave it open the rest of the time.

There ya have it i just know it is gonna be REAL hard to do it head/cam. I dont have a clue what is legal as far as supers go. You are gonna end up using every penny of the money you said about spending if ya go super though. I would imagine that a STS would be able to be legal. All ya have to do is put the stock tune in it when ya go to get emissioned. It aint like they push the car at all to even get it to spool. GL man

im pretty sure you cant SHOW you have turbo or theyll say something.ive been told that the draw of the sts kit for CA fans is that you can take the turbo off for testing easily,so keep it on,and take it off for the testing.

Never dynoed it with the stock manifolds, but with LT's and the converter locked, it was 380 rwhp. Stock was 280 rwhp, so a 100 rwhp gain.

Don't know how much $$$, I don't think I want know.

I would do the STS system as I have n=been very much in touch with STS on their CARB exemption # and they are supposed to be doing their final testing for certification on the 20'th of this month and should recieve the EO# for all GM vehicles very soon. I am a dealer for them and they work very well and would be able to reach your goals easily. Let me know if we can do anything for you. Keep in mind, if you buy your system now, the blanket EO# for their systems will cover any system, even the ones purchased before the EO# was issued, this is directly from their mouths.

These guys http://www.spmotorsports.net/welcomepagenewestcopy.htm claim they can have you putting out 500hp and pass CA. emissions. Give them a call.
