I am very glad you people do... It is getting rare to find people wanting to talk about engine stuff or do anything with engine anymore.
So what I got from niterydr is that there has to be a balance between the port size and the velocity of the air going into the engine. Basicly this all depends on the hp of the car. I didn't know about the term "sonic choke", good thing to know.
I should have used a subject matter like this I should have used a better example then 2g vs 1g. Yes they both use a 4g63 but when it comes down to it, there are a lot of changes between the 6-bolt and a 7-bolt 2g engine.
The whole tuning theory is for another thread. Be glad though that I have realized that instead of using some cheep tuning device, I am using a standalone system taking control of everything plus a wideband. Unfortunatly I don't have a ECU that is an Eprom, or the money for dsm link. I compaired prices and features of both and my decision was to go with the MS system. I do realize that money spent on tuning will make this car "perfect" A car won't run right without the proper tune. Money I will save from going with the MS system will probably go right back into tuning the car.
I should pick a turbo now. I have been avoiding picking a turbo because everyone has their own opinions on them. I should figure out what I am going to go with. then match the engine to it. I still don't know what to go with though...
With E85 I do know that I will still be dealing with knock. I should have specified on this more. With running higher compression pistions and running low grade octane (say 91) I will be having problems trying to tune out knock. Like you said, the pros of E are higher grade 105 octane (sorry about the miss information). Question is though, how bad does the grade of E fluxuates? this could completely mess up tuning.
niterydr- I didn't take it as being picked on, and I hope you weren't picking on me too much
.
I hope this thread isn't just to educate me, I hope there are other people getting information about this as much as me.
