For the last few months i'm in a search of the most up to date turbos for my TT.
I run the Protomotive modded VTGs for over a year now and love them, the car drives as stock but with a lot more power.

I know that a lot tuners like (TPC,Protomotive,Champions,Switzer) have come up with newer more advanced turbo technology that makes my turbos look old.

I want to change my turbos with something more advanced but don't know which path to follow.

My car has 4,5'' I/Cs with silicone hoses, Europipe stage 1, ECU/TCU, MKB reinforced transmition, 9FF turbine to airbox C/F hoses, Methanol injection kit, and the aged 63mm VTGs.

I believe that i have pretty much everything, i only need to change my turbos with the more advanced ones.

Some tuners use modded TT VTGs some others use GT2 VTGs, some extruct the hot sides then some others do their ownd Billet housing.

I was wondering are all those turbos a direct replacement in my case?
In case of Switzer i guess no since they use the GT series on their R911.

It would be very helpfull if tuners were explaining in simple terms how their turbos differ from others.

Talking in General some believe that extructing the hot side will cause it to over rev the turbine. Some others believe that using a very large compressor will create lag. Also heat is a main factor.

Tuners,

please give us some more information about your turbos, if this is not possible to do it in public PM is an option

 

I have a pair of GT2 modded turbos here sitting. I may let them go for a lot cheaper than retail. Discuss with Todd K.

 

It is a bit like pulling teeth to try and get some answers about the differences b/w different vtg options. Milou I hope you are able to get some answers and then share them!

I'm patiently waiting for some results from the new TPC 997tt upgraded vtgs. I haven't gotten confirmation but I believe they are based on a 65mm wheel. The biggest wheel is the 68mm Champion one as I'm sure you know. Will be nice to see some results, hopefully soon.

 

i advise you to get alpha gt3071 .. no lag , great spooling

 

SPI 911R use alpha turbos which is ( not GT kit ) and it bolt-ons %100 with stock headers and stock or ur current exhaust.

It is really GREAT choice

 

It is alpha 3071 or a3071 not alpha gt3071

 

my mistake .. sorry bro ..

 

Our packages as a whole have been very successful in creating usable power that you can drive everyday comfortably, while still providing awe-inspiring performance at the drop of the pedal. I would not get caught up in comparing specs and deciding on that alone, look at the performance of the package overall.

Milou, email me today so we can discuss.

 

What are your performance goals? That will help narrow down the selection. If you want to break 6s 60-130, I don't think vtgs will do it but I could be wrong.

 

That's exactly what I went with and love it

 

I would contact SWITZER....

 

Thank you all for your advice, all PM replied

 

I found these a while back when searching...I believe these are simular to the turbos that switzer uses...They use all the factory parts to bolt on...I called the company a while back and they where still working on the 997...This would be a great solution to buying standard gt30 turbos which requires a lot of work to get them to fit....I'll contact them again on Monday and see how their progressing...

pretty sure they work on the 997

 

That is a great option but not VTG. I'm looking for a direct replacement of the turbos, i think Champion will do the trick
