I would like my next power mod to be a substaintial increase without breaking the bank so I'm considering one of these as an option. Can anyone give me your opinion on which to go with? Eventually I would like to have both but I'm thinking if I went with the 20g, I would most likely need to upgrade the I/C and associated piping. Please chime in if you have any thoughts or opinions.

 

I don't even see it as a question. You need all the supporting mods before messing with a 20g. Cams will give you an immediate gain of 30whp or so as long as you're tuned properly for them. The 20g could give that much additional power and MORE eventually, but it would cost a lot, LOT more for everything than just a set of cams. Plus, you will need the cams if and when you go to the 20g (or any other turbo).

 

both

 

Get the turbo, more efficent for ny specific boost level resulting in lower IATs and a better ability to hold boost. Cams are great and all but it does not change anything about the stupid spikey hot air blowing 16G.

 

Cams will also help the turbo breath, 20g is only like a 20whp gain over a 10.5, get the cams, you'll never regret it. IMHO i would almost ALWAYS do cams before the turbo upgrade

 

i would go with cams first

 

Sorry but I had to . It sounded personal

 

screw MM racing...for <500 bucks (GSC/Buddy Club) brand new, cams are the way to go. 30-40 whp throughout the powerband...and have been repeatedly proven, something the 20g has yet to do in independent testing.

 

i would go cams, your turbos only makes a little less cfm than a standard 20g.

 

Yeah great cams give you 30-40 whp. Then what. Turno up the boost on the turbo and you get more gains. If you want a purely street driven mod go with the cams. You want a track mod go with the turbo. Lots of 4G63's have run 11's on stock cams.

 

that's more power than your beloved 20g is supposedly putting down. Cams add a ton of power and torque, especially top end. I fail to see why cams would only be good for a street driven evo.

a little over 400 bucks and more power than a 20g? Sounds like the better mod to me...

 

I have both,be it 264 on the intake side. You should really do the cams first to realize the stock turbos potential. I would do everything you can around the stock turbo and once you max out the stock turbo look to upgrading.

 

I would do cams first. I got 272/272 setup and above 6000 rpm it almost feels like a second turbo kicks in, you'll love it.

 

tons of evos run 11's w/ the stock turbo!

 

And some run 11s with stock turbo AND stock cams!! (just not me, dammit )
