Ok thank you. That makes sense. Now could you elaborate? When you say made the cbrd turbos, what does that mean? The housing is from Mitsubishi, so blouch r&d and made the wheels, that are added by cbrd? When you say made, could you be more detailed? When did they make what for cbrd? Was this before cbrd made the ball bearing version? Was this on the Evo 8-9 platform? I'm not doubting you, but would like to know all the facts. Just wondering why people buy cbrd and not doms if they are "both made" by blouch.

 

Also I don't remember saying they are unproven. I said they offered their turbos for the x before cbrd and FP, but after FP and cbrd entered the x game they became mostly irrelevant.

 

Blouch was the manufacturing arm for all CBRD BBX/BBK turbos, made to Chad's specs.

I know Chad personally so that is all I will say as I don't want to accidentally spread misinformation if I don't get more granular tech specs correct.

Blouch isn't really very active in the community while Chad is, so that is most likely why you saw much more "CBRD" turbos. Plus Chad is a nice guy and has much better public relations than Blouch did/does.

I tuned a bunch of Blouch Dom 2.0's on Evo 10's back before CBRD released the BBX/BBK series. The BBX (non lite) was very inline with the Dom 2.0.

 

Thanks that clears it up. Did not know that. When you say was the manufacturing arm, has that changed?

 

CBRD has moved to offering EFR based kits now.

Stumbled across this:

http://www.cavalliturbo.com/Mitsubishi

These are interesting to me (ceramic ball bearing, billet center section), but strange to me for two reasons.

1.) The turbine specs (Stage1) are 55/56mm inducer (website says opposite for ind/exd) - either way they are very different with nearly a constant blade profile and inducer-exducer. The good news is they (turbines) are made of 713c inconel (same as MHI and Garrett).

Compressor: 53mm inducer, 71mm exducer
Turbine: 55mm inducer, 56mm exducer

Advertised as a 540hp turbocharger. Not sure how the turbine could support that. Stage1 is listed as an alternative to the GT3071 by Garrett which is advertised at 475hp (see #2). Comes with turbosmart actuator with a collection of springs for varied setups.

2.) Then you have the Garrett bolt-on turbochargers that frankly I would ALWAYS choose for the price over the Cavalli due to the more proven ball bearing center. The older GT series can be had for the same price as the Cavalli ($1800 to $1900) and are proven through and through. GTX is a 300-500 dollar premium over the GT aero profile. You get 713c inconel, ball bearing and a turbine housing as good if not better than MHI. They made a mistake on the internal wastegate flapper when they first released it (failed open killing boost). They made it right, but the evo community never forgets.

3.) You can go ghetto Kamak/Kinugawa which is what I am in the process of doing and am documenting here:

https://www.evolutionm.net/forums/ev...ett-kamak.html

Downside is Taiwan built, and 718 inconel turbine which is 300-400deg lower failure temperature than 713c. The 4b11 doesn't exactly run cool, so I will be staying rich. The scoobie guys love these things, and I have high hopes. If it fails I am jumping straight to Garrett and not messing around with journal bearings. One more positive and negative is 9-blade STS turbine that should flow more than a stock TD05, so in theory this should beat a FP 71HTA upgraded TD05. Negative is no stock compressor housing with anti-surge. Surge will have to be controlled by ECU or swap a 20g anti-surge compressor and weld up your own outlet zig zag for the stock heatshield.

my 3 cents

I agree with whoever above that if there was a stock frame EFR for 2 grand I would jump on that in an instant.

 

Thanks for chiming in Bryan-

This is all correct-

our wheels were typically a little massaged- over what Blouch offered- and the reason they were specific to us we because of the level of testing/development we put into it with Blouch- the Ball Bearing applications were done specifically for CBRD- which is why you really didnt see them elsewhere-

check out turbo charger systems on FB. They are doing some cool affordable things for the Evos.

 

affordable and proven dont always go together

The valve cover has two vents, one to the intake tube, and on the intake mani with a pcv valve. The radium can needs bigger fittings to work. I have the dual radium kit on my car with all 10an hose and fittings (they come with 6an, not big enough). One goes through a check valve to the intake mani (this one also has a 3/8" restrictor so that the car idles at a proper rpm, and the other goes to the turbo inlet pipe.


My setup works very well, It 100% solved the leaking issue I was haing with my bb red, which was leaking quite a bit. However, a lot of guys also seem to have good luck with the VTA types setups like STM's

 

driven fab or kozmic VTA catch can's with the -10AN lines work quite well.

 

So, do you guys think the Garrett GTX3071R (Stock replacement, .73A/R, 56-57LB/min) turbo be able to get me 400whp on California 91 octane pump gas? Or do I need something a little bigger? FP Red/EF3...
All bolt ons, stock cams, stock Ex mani

 

I have brand new JB BBX for sale...I love this turbo. on E85 i made 470whp and could easily make more but i'm on stock block

 

Since they haven't been mentioned; HKS offers the GTII 7460 Kai and the GTII 8262 Kai for the X. The 8262 is good for ~450 whp and it's what I run on my personal Evo.

 

Running an FP Red that is making 419awhp and 377tq in my MR. Was talking with them this morning and was considering upgrading to a FP Black.
