Please tell us why and do we need more mods for them??

 

Yea, Paulie tell us how those 20's are working out for ya!

 

LOL good one Paulie

 

So... Are we serious about the billets? Or...?

 

Ice what are your goals? billet 15g's will do 500 on pump gas and 600 on ms109, 20g will do probably 50whp more but it will require a lot more support.

 

FlyingGuy,
Before I had bigger ICs, Y-pipe, TB and Plenum, I actually felt that those 71s were lack on top; maybe one of the reasons was because I have a Tip. With the bigger piping, the car feels much more alive on top. I don't know your driving habit, but my driving style is some freeway pulls (mostly under 140) and a lot of windy road. Those 71s really fit my style, a lot of low end, good mid-range, and decent high end.

I have a question, my 2871s are ball-bearings; if you convert yours to 71s, will they be ball-bearing?

 

I don't really have a HP goal so much. Obviously the higher the number, the better. But I do daily drive my car. I basically want as quick a car as I can without doing rods, having full boost at less than 4k ish. As far as numbers, I'd like to be as close to a 5.99 60-130, and would like to do a 10.99 1/4 mile, AWD if possible. I'd assume I need race gas for these goals, and I'm comfortable with that. I have spoken with Todd K in length about this, and have his suggestions well in mind. I'm just wanting to see what others think. His suggestion is utilize the hardware I have, and cram a 2871 inside. He has seen good results when those are pushed on race gas.

 

I believe that Blouch does a journal bearing 2871 to throw in these early generation A28... I'm still limited by the K16 hot side. Is this the same turbo you have?
Also, any thought on a billet alternative to cram inside here? I guess I could call Blouch about that...

 

Mines are the Garrett ball bearing GT2871s, pre-A28 turbos. I believe the A28 or billet have more potential; but if I have 28s (older) already, I won't even consider them. If you decide to do it, it's not a bad idea to do a dyno before and after; I'm really curious about the numbers. Good Luck.

 

I'd like to do a dyno pre and post. But I'd have to drive well out of town, at least an hour and a half. But we will see.

 

When it gets finished I will report.

 

Easy grumpy..

 

 

not sure what the benchmark is for these itty bitty turbos on 91 octane, but i just ran a 7.39. waiting for Mike to verify!

 

I have K1639's flow 39lbs 1 less than k2418g's
You could see the hot side just starting to choke and temps were just in specification. (A 4" IC would have cured that.)
We could have developed a K16/40+ but decided the hot side would be the problem . Overall these Turbos really really Rock and that's form some one with a full K2420g set up. He recons my car is quicker than his in the mid rev range.
My car was quicker than the factory GT2RS and quicker to 100 than a K2418g car ( testing at Bruntingthorpe Car Testing grounds)
