Mike or Sam. Is there any difference at all in the two wastegates?

Dzel · 04-19-2013, 02:35 PM

Going with 18g's myself a buddy of mine had an Srt4 with upgraded everything but on his exhaust he left it stock and ran an electrical dump that he could open or close at the push of a button. I would like to do something like that also

Yup I'm going with the 18g internals and HKS plugs. The 18s will breath better and give you room to grow if more power is needed later.

Yeah for a track guy, I'd totally do open dumps off the EWG's... So awesome.

Probably run some little pipes out to the sides of the car though so it isn't spitting fire into my underbody lol!

Dzel · 04-19-2013, 02:53 PM

Is not fire is awesomeness!

SPOHN · 04-19-2013, 03:08 PM

This is fun. Looking at one step colder plugs now.

brucelidat · 04-19-2013, 07:12 PM

So how much for the extra mods that are recommended to run a 7at reliably? Is there a 7at package?

brucelidat · 04-19-2013, 07:59 PM

so I read that the minimum requirement would be a trans cooler for an auto, but what would be the RECOMMENDED supporting mods,not the minimum?

SS_Firehawk · 04-19-2013, 08:01 PM

trans cooler and valve body upgrade

brucelidat · 04-19-2013, 08:05 PM

Sorry, I don't know my mechanical stuff so much. Do you have a link to the valve body upgrade?

brucelidat · 04-19-2013, 08:24 PM

NM, found it. So valve body upgrade, trans cooler, anything else?

KaienZ34 · 04-19-2013, 09:05 PM

Tune the trans/increase the line pressure with UpRev.

DEpointfive0 · 04-19-2013, 09:06 PM

Better flex plate, GTM is working on that one too

jpritche · 04-20-2013, 06:20 AM

Manual tranny swap /thread.

Dzel · 04-20-2013, 07:39 AM

Or a gearbox upgrade!
