Is everyone in wait and see mode? I am in the market but I don't really want to pull the trigger on anything yet because is seems like there are a handful of options that will be available soon.

I am also concerned with buying a turbo that hasn't been proven yet and I don't want to be the guinea pig

What is everyone else doing?

I would like to get a inlet/turbo option that will give me 500 to 550 at the wheels on 93.

[Island Road]

Personally I would wait. There is MMP, RB and Hexon. I think RB and MMP are going to be similar and Hexon is the only company offering a larger size A/R on the exhaust side.

I am sure all the companies are going to have great results though. I love all the testing MMP is doing but I would hold out to see how Hexons perform.

RB has been proven time and time again

[3000GT MR]

Solo Is coming out with the right idea of having a higher flow exhaust side. Im curious as to see what they'll do

[matthewo]

nothing but good for us end users, time to beat on my old stock turbos.....

[Milan]

im waiting for the market to get more competitive. so far MMP seems like the most thought out

[csu87]

Im waiting for a top mount twin turbo setup. Now that would be sweet.

if stock style TT were not already a cluster with the coolant lines and all....

I think most may have to run a fine line with being price competitive as there has to be more of a reason than torque down low to keep people from going to ST.

Yeah, TM TT setup would not be cost effective and not many people would want something like that. I'll be able to either fab my own manifolds up, or have a friend do it for cheap if I end up going that route. And i can get AN fittings and lines pretty cheap through my company's accounts with suppliers.

It's great for us owners to see constantly development on a 8yr old platform.

I'm probably going with MM depending on price. I really want more top end power. Making gobs of torque down low is only useful for daily driving, not racing.

I will be making some purchase over the next few months. I am not interested in upgrading any drive train (DCT) parts so what should be my target for whp and wtq. I would like to get somewhere between 500 and 575 whp on 93. That might not be possible with what is available today but I would like to get away from using E85 because it is not convenient to get in Charlotte. Can you believe that there are no gas stations in Charlotte, NC that sell E85.

[csu87]

I've heard keeping your torque to around 500wtq is a good number. Seen people report slipping after that. Not sure if that is for the dct or standard auto though. And like most things, is car dependent.

Also keeping torque from coming on too strong too quick will help.

Anyone know anything about the Hexon RR500? What stage? Any dyno numbers?

I am interested in the new larger turbine housing turbos. Can't believe none of the manufacturers have gone that road before now. I understand there is an investment involved, but for what they are charging for upgraded twins I guess it makes sense to keep going with the ridiculously high margins they are reaping currently. It baffles me they are demanding so much without building them on a quality frames such as Garrett or precision and being Ball Bearing units. Non BB Chinese turbos for +$3k blows my mind even with mating to the stock manifold housing.

Ultimately, I'm most shocked no one has tried Garrett GT2860RS units. I bet they would be s great fit for this engine. Does anyone know if its been tried?

A/R is about subjective preference - do you emphasize spool or top end power. Personally based on MMP "feel of the car" results and what has been dynoed with less modified stock frames, the modified stock turbine housing i.e. rather small A/R, is good for 700 WHP which in my opinion is more than enough for this car. So, I'd pick the smaller A/R for quicker spool rather than go for larger A/R and 800-1000WHP that could be preferred by someone else.

When it comes to Garrett, the way to get them fit would be what Hexon was talking about doing, casting a slightly modified turbine housing that would fit to the OE system.

You aren't making 575WHP on pump gas with stock frame turbos. Hell I wouldn't advise anyone try to make much more than 500-530WHP on pump gas regardless of turbo. I've never boosted much past the wastegate on pump.

That's about right. Mine hasn't gotten too pissed at me yet.

They're partnering with Frankenturbo, they just started a thread. I'm curious about theirs since they're local.

AR changes offer a variety of benefits especially with new sized turbine wheels. You can achieve great spool and reduce turbine inlet pressures which is like regaining free horsepower without the loss of spool. The attack angle of the exhaust gas on the turbine is very important and simply adding a larger wheel to the same housing essentially is like reducing the AR by effect. It doesn't change the actual housing AR just the increased attack angle which generally is what a smaller AR accomplishes. Variety here is going to prove very interesting results for this platform. Something its been severely lacking. I am leaning towards a single setup mainly because I want the reliability that the Garrett units provide as well as the easy housing swap ability. Variety is the spice of life!

Looks like SMS, Solo Motorsport upgrade is close to what you are talking about.

just go single, thats how the engine should have come out from the beginning
