Woodster is the the setup you describe a pump gas oriented one?

Thank you,

Jane

 

Hi Jane,

I can share a little of my experience going from 18g's to 20g's. The 20g's on pump gas perform similarly to 18g's on race gas. The upgrade is significant in cost however. I would suspect that if you have already done a clutch it will still cost you about 6K minimum for the hardpiping, IC's and various other tidbits you will need. Is it worth it? Every penny. I think the 20's are one of the best all around turbos for these cars and I've been fortunate to drive a few of the various setups around from K16/16g cars to GT30 cars. The spooltime is almost zero the power delivery is extremely linear relative to the power it makes. I wouldn't think twice about doing the upgrade. If you plan to run pump gas primarily you can tune accordingly and run 1.2bar all day every day.

Bobby's 2001 white 996tt was I believe the first one to be fitted with 20gs.. granted, he ported, polished, clipped the turbine wheel... and even extrude and honed the hot side.... that car gave a many nightmares... even the 30rs... but the owner was an elite in what he does... always pushing the envelope... thus the great results...

 

That's one of the cars i've been lucky enough to drive actually.

 

In minnesota?

 

Yup was there about three weeks ago.

 

Hows it running? U know there was a few hands in there before it came to MInnesota..

 

Runs very well. Wasn't on full kill though boost was waay down.

 

Ben,

On 91 Octane I would not run more than 1.1 bars.

 

I would agree depending on who tunes the car and whether or not its an off the shelf file or a custom file.

 

Ben lives in Texas,where we have 93 oct. I know it is confusing.

 

I don't want to threadjack here, but what about lag on the 20g's ?, personally I like as much torque down low on the street. If I were looking to take the next step past 18g's, taking the torque down low into consideration (and I mean down low as possible, peak TQ under 4k), what turbo is going to give me this without completely sacrificing HP up high ?

 

i agree with jits, on straight 91 hell i wouldnt run anything over 1 bar.

 

Alpha series turbos,...but at $5k-$6k a set...a $1200 upgrade seems like a nice compromise...

 

The 20's with the hard piping setup actually have less lag than the 18's in my experience. They are probably one of the best all around day to day turbos because of the low end torque is phenomenal. The 20's are the turbo you are looking for ....... I'd give you a personal guarantee on that.

EDIT: Just looked at your mods. The upgrade to 20g's is a no brainer for you!! Do you have an upgraded clutch too? If so, I bet you could have everything done including the switch to 20g's for about 3-4K (Hard Piping, Additional Fuel Pump, misc.)
