Maybe this is fodder for another thread. But can you point out the differences between GT2 and X50 if any?

 

I bought steel brained lines with fittings....

 

Markski that's a great idea but I'm shocked that you, of all people, went that route since they are heavier than solid lines.

 

steel brained lines? my college days just flashed....

Our kit does include steel braided lines, new fittings, and new check valves for the oil system. Since the can is designed to be used with the Garrett turbo, not sure it will work for those with stock turbo setups. We do a TON of line work, so if you know the ID, length, and fitting type, let me know and we can make you any line for cheap

Cant wait for tomorrow! X50 tip time with the turbo kit!

 

You bet I do!!!!

ari, the GT2 and TT X-50 have several differences the biggest being the first is RWD and several hundred pounds lighter, however the two cars have identical engines and intercoolers so similar power with the K-24 turbos instead of the stock K-16's so start out closer to 450hp instead of 420.

 

LOL sorry I meant steel braided lines...

here is what you need.... fits stock K16s as well as Garetts.... one end goes to the check valve ans the other to the turbo... However, on the garetts you need to use a special restrictor that usually should be supplied by the turbo maker... its a fitting... here are some pics of my new set up.....

 

Dan and Marksi,
I was referring to the oil sump lines, not the turbo feed lines. They bend when removed, distort, and then become difficult to reinstall. It is easy to strip the threads as both the male and female threads are soft aluminum.

 

Dan, what are the pros and cons of the Garrett turbos vs hybrids?
Also, pros and cons of an external waste gate? how will the underside of the car look after awhile with exhaust dumped under the engine??
thanks
tom

 

Markski... we know we know! but brains! come on that was funny

roadsterdoc we could supply that as a steel braided line but the factory one works fine. I can say that if you were to mess your OEM one, we could supply a new one for you.

Tom -
most of the time hybrid turbos are USED if I am correct. you are taking your 16 or 24 turbos and having them machined to fit different cartridges or exhaust sides. You are what they call frankenstein' them. I am not a turbo builder nor expert, but I would assume that an off the shelf ball bearing Garrett turbo with no modifications to it specd out from Garrett will last you longer, operate more efficient, and have better performance over the life. But I could be wrong...

What I do know is that the external wastegates far exceed the internal ones. On a stock turbo, the internal wastegate opens into the path of the exhaust gas. That flap literally opens up right in front of the turbine wheel. Restrictive. On any turbo car that we have done external wastegates with, you are bypassing the stock exhaust system and allowing the turbo to be more efficient. It almost always yields a larger increase in torque and since there is no hinderance with the turbo, you gain more HP's. you will notice on the picture above of the underside of the car as well as the new pics I will post today, that the external dump pipes point straight to the ground. The underside of your car will look no worse then it already does For those wanting to have some fun, extend the dump pipe to your exhaust system and shoot flames!

 

Dan, do you have any timing of that X50 tip with your kit? I'm particularly interested since my car is also tip

 

will be done today. we are all just getting in the office right now. techs will be starting it shortly. I will have pictures up too

 

Hey Roadsterdoc and others, AFI has just informed me that the Oil cans are 6061 T6 aluminum and will not strip like the factory cast parts.

 

Tom,

To briefly answer your question the hybrids make good power, but our set-up is a true garrett turbo with a CHRA ballistic cartridge. This is in my opinion the best center cartridge out there. I can't speak on behalf of the hybrid guys as I am not sure, but I don't think they use the CHRA housing.

Also I personally did a lot of compressor chart sizing and I found these turbos to be the most efficient. These turbos will continue to make power at higher and higer boost for the guys that want to get a bit more crazy.

This is more or less what we used but if you do the math on it, the turbo vs air flow/displacement rating is very fitting.

Hope this helps guys,

The kit looks very nice Dan, thanks for providing another viable option. I like the fact that you used a T3 flanged manifold to allow for such a wide variety of easy upgrades, very cool. From the pictures it looks like you used a .63 A/R for these dyno results, is this correct?

Could you post an overlay of this dyno plot with one from a car with K24’s (or some K16/K24 based variation) that you have dynoed? Obviously the peak power numbers will be different. But it would be interesting to see the spoolup/area under the curve differences between the two. Thanks.

 

Hey Brett,

To answer your question it is the .63 AR. You could go with different size anything really on the kit and that is the beauty of it. As long as the turbo of your choice is a T3 based foot print you can run a lot of things up to I would say a GT37R. Now twin GT37R's would be nasty.


I will post up some overlays of the different kits later on today.

Thanks,
