I have the 420a but my intentions are not racing it, im gonna make it a daily driver. So stick around with these guys advice, voice of experience. The 420a cant go a full month without idling badly -_- (in my case, bad pre-owner...)

 

gs-t or gsx hands down. i'm surpised my name hasn't come up yet lol. about 2 months ago i had EVERYTHING needed to boost my 420a... i had about 2k invested in the build already, spare block, complete engine rebuild kit, turbo, fmic, ic piping, everything but i realized that once i finally got in there i had about anothe r1500-2k of spending to get it running safe for the car and tuned... it's not worth it. sell your car and just get a gs-t or gsx.

natewesselink - don't put bad/incorrect information on here like this again, not only is this completely falsified but it's alllllllllllllllllllllll over the forum that this is a bad idea. there is a sticky at the top of the forum about it.
