Disagree. There really is no proof of what a properly tuned vs2 will do from a dig yet. Somebody in here went a low 12 at 120mph. I'm willing to bet that car was not yet finished tuning wise. Not to mention if someone throughs the transbrake tune on this turbo and you have a tbraked stock turbo car, it won't even be close on a clean run.
You must not know who prefweld is.
Who are you to say my car is is not tuned properly? Whatever, when you get your ass handed to you by a stock turbo car, don't say no one warned you, because I did.
And again, I'm not saying it can't be fast. I'm saying it won't be without adding more parts. You have a very good drag racer saying it has a 11.80 in it without a convertor and this same guy ran 11.6 stock turbo. Hello. For those of you living in a Nanny state this is a great option, it looks almost exactly like the stocker. You can not tell it's not stock on my car, I even put the heat sheild back on, total sleeper look.
Add a convertor and it will eat up a stock turbo car. If you don't like my honest opinion so be it.

How do you think it will perform on a transbrake tune? That is the route I am wanting to go vs a converter. I can build 7psi off the line so far on 93, but it still doesn't come out of the hole like the stock turbo did.

Alright let's just start with the attack on me first. I never once said your car is not tuned right. I said we don't know how a properly tuned vs2 car would do yet. I probably should have used the wording a "finalized" tune vs2 car. Also if you look at my signature below, I'm still stock turbo. So as far as me getting my ass handed to me by a stock turbo car, I'm sure I will, I'm not on a e30 tune. Anyone who can halfway drive will come around me if that have that tune on their cars. I'm sure with a convertor or a t-brake tune a vs2 car will eat up A LOT more than just a stock turbo eb on the street or track.

If the transbrake tune gets you a 2 step added and they can play with the timing and A/F mixture to help build boost, that might work. If all it does is lock reverse and 1st gear, I dont believe it will change anything as its the same as foot braking, unless your having a hard time holding the car at 7 psi of boost, but I assume you dont. All a transbrake does is apply low gear and reverse and its held by a push of a button, then you release the button as oppose to taking your foot off the brake petal. This is how pretty much all transbrakes work, I believe ours should be the same in this trans as well.

Better with a 2 step TB. It's just gonna be hard to get it to leave as hard as the stocker. I think/hope with more tuning and time you auto guys will have a nice setup. Us MT guys can't get around it dropping out if boost on upshift.

APX623/Sean, sorry not attacking you at all, not attacking anyone, just understand this is not a fit all turbo. For me it doesn't fit, for others it fits fine.

From my understanding it is basically a two step setup, but I have seen everyone on here calling it a "transbrake tune". I think that is the route I am going to try to take, but then again I am interested to hear your thoughts on your converter when you get it installed and run the car.

Your best shot at keeping boost up during shifting is with flat foot shifting. Cobb's fuel cut implementation of it isn't the best(imo), but if you wanted to get really serious about it you could pick up a wot box. That is if you were willing to do the wiring to install it. This would allow you to use ignition cut launch control and FFS. That would basically give you the best case scenario for keeping boost up during shifting as well as building boost for getting off the line in a MT car.

Edit: I don't want to thead jack too bad =). The turbo looks promising Tony. Seems like it's going to be a good value for the money. Especially for people who don't want to spend big bucks for a full turbo kit.

Even with FFS I loose about 10psi on the gtx turbo. Thats a big reason why this vargas or any JB turbo isnt good for the MT cars. The response time on JB cars is shit when you cant FFS and hold 20+psi

That's why I mentioned the wot box. It will get you more vs cobb's fuel cut implementation. If you are serious about racing it might be something to consider.
