my take:

domestic vs. import:
i have much respect for the domestics. although i am a nissan / import enthusiast, there is no way that i can over see the amount of power that some of these v's produce now-a-days. ford, dodge, and gmc are great car companies. efficient or not, these companies make powerful cars. indy cars are probably less efficient than 90% of the cars out there, how come no one complains about the amount of power that comes from that and how un-economic it is?

srt-4:
although it is a quick car for a relatevly low amount of cash, the car is powered by MITSUBISHI. sure it is all mopar and what not but the turbo is a mitsubishi turbo designed to spin in reverse in refrence to the regular mitsubishi turbos. the 2.0 engine is engineered to exist with the turbo and is engineered well. without the mitsubishi turbo, however, the engine would be crap.

domestics:
companies like gmc had such a big issue with the 4wheel steering system that they have just recently engaged onto. the idea is great and all, but nissan and honda have been doing the 4wheel steering on early 240's and preludes as well as other companies.

turbos:
it comes down to compression. there are pleanty of na cars that get boosted and have a significient amount of horse power gain. people turbo charge the integra gs-r engines and they are powerful and economical to some degree. just because a factory turbocharges the engine, i believe, does not make it any more or less road worthy. it is all about customizing cars and what not. i would rather wait in line and see a twin turbo integra, than wait in the same line to see a eclipse gst, stock. turbos are efficient and economical in most aspects. if you want to turbo charge a go-ped, go for it. ill be waiting in line to see it high compression is for na engine and low compression is for the turbo engines. if someone were to rebuild their engine (someone = someone who knows what they are doing) with different pistons and bore and stroke (to rebuild a na engine for a turbo application), that in itself should make the car more respectable than any stock turbocharged car, left stock that is.

advice:
i need to stay on topic and get down off my soap box. if i were you, id pick a turbo that you want. do you want high speeds (larger turbos) that will take a while to spool up, or would you rather perfer a quicker spool time (smaller turbo) which has quick acceleration but the high end speed wont be as much? it is all about the balance. you need to sacrifice high end speed or low end acceleration (turbo lag). keep in mind that the larger turbos will run you a considerable amount of money as well. after you pick which turbo you want to go with, you should pick out which type in intercooler, fuel management, wastegate, bov, and all that other stuff. it is obvious that if you go with a smaller turbo, the horse power gains wont be as much, but you wont have to spend the extra cash on the extra large fuel pump, or other accessories. i HIGHLY recomend that you go about piecing together your own turbo system rather than buying a complete system from some website. FIGHT THE MAN!! good luck and keep it custom
