I gotta go to NAPA first and get some o-rings for my fuel injectors. I tore one up taking it apart. Hopefully I will see some gains. I am completely stock, except for some weight reduction. Oh well I am rambling on. Laterz

This pic isn't a finished port. I would say half way done.

I think I wanna do it, if I can find the time. No headers here, but one of those Rotary Performance pipes (with no cats) and a K&N type cone intake. Should I have gone with the headers in the first place? I just figured it would be quieter this way, and I can slap the cats back on easy if I want (I kept the air pump). Am I gonna see some ok power gains?
Thanks for the mileage info.

Is it normal that my rev buzzer is now hitting between 6000-6500?
Overall I am pleased with the results. I had to wire the aux ports open again, they are still not opening?????
BUt now my car lags worse than an old 930 hehe

No... that's not normal... mine is still at 8k sharp (7k for S4). I think your tach may be off or something is screwed up. Just search for 'early redline' or 'buzzer comes on early' or soemthing like that. I know it's been a common topic.
Yeah, you really need your 6-ports to be functional with porting, otherwise you will actually LOSE torque .

I say, GO FOR IT!

Hi, I have a 5zigen Fireball Exhaust system (muffler/midpipe) and just installed a high flow downpipe with a single high flow cat on it. If I were to port my engine, would I be noticing a significant gain in performance?

Agreed, vacuum/intake leak. Symptoms : exactly what you described .
POSSILBY, you could have fucked the cold start screw and/or linkage/assembly.. if so compare the entire throttle body to spec in haynes or FSM... be sure to read if it's for COLD or WARM. But this is highly unlikely if you read my warning in the write up .

check for the vacuum leak, mine did that after porting but i also took off the bac. after staring i hold the revs with my foot up at like 2000 for 5 min in the driveway, after that it idles roughly but it holds idle. check all of the idle adjustments as per fsm and make sure the tps is set.

costs more? I dunno....
Why didn't they put on headers or a cone filter? Why did they implement a useless sub-zero starting system? Why did they use faluty PD's? Why didn't they use a ball bearing turbo (which they DID consider)?
