street ported or not ported at all???
if i get my engine street ported will it still pass inspection?? if i just rebuilt my engine will i still be able to produce the same amount of power as a street ported engine?? my big concern about porting my car is about the inspection i heard that if i get it ported it wont pass can some one fill me in why it wont pass.............

Well,
1. If you street port your engine, you will have to take apart the motor. So you may as well rebuild it. 2. I have heard that a MILD street port can pass emissions testing, but I cannot confirm this in anyway. I certainly don't know tx emmisions laws. Porting a motor allows more air flow, more air flow in means more emmisions out the other way. |
The issue is not more airflow, but more overlap between intake and exhaust.
Mild streetports should have no problems with emissions but it's hard to define "mild". Something like the Mazdatrix template should be safe if you don't go nuts on the exhaust port... |
to add to your question about if you would be able to get same power out of just rebuilding your engine as you would if you got it ported, no. just rebuilding your engine will only bring it back to life and give it the power it was already made with. now if you port the engine you are adding horse power to the engine that it never had. as far as passing inspections, emmisions would be your only problem but as they both said is passable depending on the ports you decide to go with. also my area doesnt have any emissions at all so anything goes. porting your engine will not have any effect on a regular inspection.:nod:

I'm not an expert, but porting will require a good tune. A poorly running car could yield poor emissions.

I believe that Texas emission laws differ per county. When my car was registered in The Woodlands (Montgomery county) I had to "pass emissions". If I register my car in College Station (Brazos County), they do not require emissions.
If your emissions system is in good, proper working condition, I see no reason why it would not pass with a mild street port. However, in order for you to take advantage of the power porting creates you will want some kind of fuel management, intake, exhaust, etc. Which could lead into other issues if you eliminated your cat, tuning, etc. Overall, Texas is about as relaxed as they come in regards to vehicle inspection. The only thing you really have to worry about is how strict your county is on emissions. If you happen to be in a strict area, there is always someone willing to work with you, if you know what I mean. |
Won't these cars be exempt from any emissions testing soon anyway?
|
mine passed emission, I did the good ole' jrat trick and it passed on the second try. first try the kid kept revving the shit out it.
i'm in denver so it might be easier to pass then in texas. so don't take my word that yours will pass. |

If you just clean up the runners you should be safe. You will only re-gain lost power from a rebuild, do it regardless of whether you port or not.

In Texas cars 24 years and older are emissions testing exempt... One more year. |
in NY, its 26 years.
still 6 more years to go ... :( |
