Hey my name trevor I'm new to the page. I've read a lot about brainiacs and underdogs t3 50 Trim build. I decided to order one my self last night and noticed right after that I got the wrong one because it didn't have an internal waste gate and didn't have the vband outlet. Other then that I believe it's the same turbo. The compressor wheel inducer is 42.50 mm and exducer 60mm and the turbine wheel inducer is 64 mm and exducer 46mm. Here is the link to the turbo Universal T3 TURBO CHARGER 45 trim STAGE III HONDA ACURA VOLVO AUDI JETTA GOlF | eBay

so for those of you that know about the turbo I'm talking about, is it the same turbo minus the waste gate and vband? If it is I will just go for a external waste gate setup. The same one underdog did.

and yes I know I am a noob.

 

This is the wastegate/v band adapter (probably). T3 T3/T4 5 Bolt Turbo Downpipe Flange To 2.5" V-Band Conversion Adaptor Kit Set | eBay

Yeah Unfortunately that won't work because it's for a turbo with a 5 bolt housing the turbo I bought has a 4 bolt housing. Thanks though

 

The turbo you got is going to make your first turbo experience really hard.

 

Okay but why if i get a v-band adapter and go with an external waste gate I should be fine right? I guess I could return the turbo but it doesn't look like the one with the internal wastegate is even for sale right now.

 

Please don't create any more threads. just this one is enough, we don't want to destroy any more brain cells.

I deleted the othetr identical one is DIY discussion

 

adding an external gate is a lot less DIY friendly. adapters suck. return it, wait for a better turbo. a 2554 or 2560 is my advice.

Or just buy an MK turbo kit and be done.

 

the Borg EFR 6258 would be a a great choice as well

 

Also I will probably be getting rid of my turbo setup this winter to put in a 1.8 if you waited.

 

The rear v-band housing does not bolt onto that turbo correctly. Only 1 of the holes line up on the housing that comes on it and the v-band adapter piece. I don't think it is possible to redress to make it fit correctly.

 

Well thanks for all of the advice and suggestions. My turbo and taco taco manifold arrive at my house today but I'll probably be sending them right back. Just one last question and then I'll put this subject to rest. What if I ditched the vband adapter idea and just had a downpipe made with a 4 bolt flange that would bolt right up to the turbo and then attempted the same external wastegate setup underdog did? I understand it may be harder then I think but I'm willing to take a risk with the 120$ manifold. I'm confident I can do it but if I mess up oh well.

i fabricate. If someone wanted a custom DP with external WG, I would probably charge you at least 300, probably more like 400. Unless your fab guys work for pennies...A lot of F-ing work right there, especially for a 1 off part.

changed my mind, external gate adds a lot of complexity. my price just went to 500.

 

Most downpipes are 400$ anyway and if i went with the taco taco I have to get a custom down pipe no matter what. Underdog makes it look pretty simple. I could understand that it would be very complex and hard if I was wanting to recirculate it into the down pipe but I would just make a open dump . What makes it so much more difficult then an internal wasgegate? I'm sure I'm missing something here, I just don't know what it is.

 

By committing to the wrong turbo and continuing to buy parts when folks are telling you to hold up, you're just going to keep making life more difficult for yourself...

There have been builds done with the tacotaco manifold. Why not find a few of those and read what folks did for their setup?

I bought my setup from a member here and he did the ewg thang on an FM manifold. My build thread has pictures of his work if you're going to keep on going down this path.

Point is, you're going to spend more time and money doing things this way and get endlessly frustrated. If that sounds fun to you then have at it, but there are so many options these days that it's facepalm worthy. Hell the mkturbo setup is awesome at a solid price and the kraken manifold on the classifieds looks pretty great and is a very reasonable price too.

 

A VTA wastegate will be miserable after the first week. just my VTA blowoff with a filter to muffle it is pretty loud and attention grabbing. not necessarily what you want.

a merged External set up is not worthy of a stock bottom end, **** turbo. that is for megabuck builds. you are not that.

 

 

Why don't you just buy a MK Turbo kit. Seriously. LOL @ people buying $200 turbos then having to pay $1200 to fab **** up to make em work, and they still suck. At least buy a freaking turbo that we have kits based on. My churbo cost $165 and bolts to damn near any available manifold and downpipe, I don't get it.

I've also not seen one mention of engine management. Better get a hold of someone who sells power cards, stat.

 

do this

 

The turbo I have is the exact same turbo used in the mk kit only difference is I didn't get the one with the internal wastegate and vband....
