did you find out about the shop that supposedly got one of these magical transmissions?

 

No big shop here has every touched this car, or even thinking about touching it. I could be wrong, but I think I'm the only one here modifying it. Of course my friend has one, but he is waiting to see what mine does when it's done. BIG PLANS, BIG!

 

so about the factory +1 turbo with respect to the 20T compressor wheel.
Mitsubishi isn't releasing a map... however mike at Blouch says the 19T is a good place to start for comparison purposes. so it moves 500 CFM at the raged edge.
the 20T will move more (25-50cfm???) and because of the nature of the turbine housing it will effectively act like 2 turbos instant response and higher flow near red line. from initial impressions the RDX is very smooth and this is attributed to the turbo now being less restrictive on the turbine side( 9 blade now vs12 blade stock). highway manners are very nice and cruising at 65-75mph it is no longer boosting on flat ground. any tip in at more then 2000rpm results in smooth linear acceleration. it feels like I have a mountain of TQ!!! once the current software limits are resolved I will finish tuning and go to the dyno for numbers.

would people like to see the dyno done with an ETS or stock location intercooler so that you could see what it will do for you? or will the front mount be ok? I don't see there being a huge difference in the numbers but highway performance would be different without a doubt.

 

I'm interested in seeing what it'll do. I've never seen a 20T factory mitsubishi turbo probably why there's no compressor map. I've read mixed reviews on that wheel from Kunigawa, so post whatever you get Intercooler makes no difference to me.

 

Exciting stuff here!!
Would you hook up your stock IC, as I thought you sold your ETS?
I would be interested...

 

did i miss your write up of you upgrading your wheel and stuff? any videos up on how the rdx responds??

 

I too am curious how this turbo wheel upgrade works. I should be installing my DP this season and would like to more while I'm taking things apart.

I'm wondering, is tuning a must if you're changing the wheel? Not saying I'm not doing it but unfortunately I don't think I can do it right away.

 

im going to say wait for the down pipe because then you could do it all at the same time and it would be easier. once I get the MAF scaling issue worked out it will be off to the dyno and then we will see what she can do. it feels great down low to about 5,000 RPM but without the ability to run 2.2 boost target across the board it doesn't carry the initial surge throughout the entire power band.

 

using the stock intercooler for now. tread stone is on its way into the front mount position in the near future. just takes time and I'm running short on that. be patient and just save money I'll try to pester Doug at hondata and get this MAF issue pushed through.

 

Yeah I have the downpipe already but I'm wondering what I need to do the wheel upgrade. I definitely want to do it all in one shot

 

With just a intake, catless downpipe and injectors this thing cooks. Once I get a retune from vit it will be off to the track. I'm going to push the stock turbo to the max. One day I'll do the wheel upgrade but I feel its a fun challenge on the stock turbo.

 

looks like Collin is going to pay Blouch performance turbo a visit!

 

Coming along on your turbo upgrade progress?

 

yes its going just slow vit's a busy guy. doesn't help that I keep changing things out of necessity. new cat back cause the old one had the flanges rot away... changes things enough to need to account for them.

 

If you want someone to tune your car pretty quick PM Domgsr-t. His been helping out a few member on the TL side with tuning both N/A and turbo charged cars.

He can usually do one map a day turn around.

I really want to see what that new turbo can do since I been looking for an rdx for the wifey. Need something with power, good mpg, and SH-AWD

 

nah im sticking with vit i trust his work and so far he has been very understanding with my build and has made consistent gains.

 

should have some track times for this tonight!!! ill post slips and maybe some video if im lucky!

 

Pictures too Wrench. Can't wait.

 

This should be good!

 

13.93 in drive full weight. only got 2 runs.

might be able to get some track time in this coming Friday.

 

Welcome to Blouch Performance Turbo - www.BlouchTurbo.com

these are the guys you want to talk to. look for a dyno compairing this turbo upgrade to a stock turbo.

both builds were tuned on the same dynapack dyno on different days.

inovative motorworks 3" intake high capacity fuel system stock everything else.

yes we both have flashpro.

 

this is the aforementioned dyno graph

 

posted these else ware but here are time slips of what i've done so far.

also planning to go to the track November 14 at Cecil county drag strip. come one come all!!!

 

this is the cost of a turbo upgrade from blouch performance turbo if you don't need a new center heat shield. i have them if they are needed. if you want me to work the turbine inlet i'll remove casting lines and smooth things out.

 

Amazing Wrench. Not to ask the obvious, but does your butt dyno notice the difference?

 

interesting.. did those just crack over time? kinda curious on if this will be a fault in the turbos later down the road

 

Huh I didn't know the stock turbo was a TD04...that's the same that the old WRXs used to use (maybe still do I'm not sure). There were tons of turbo upgrades available on that platform because they ran out of steam pretty quickly. I ran a GT35R on my old STI.

I like the thought in the upgrade but honestly for that much you can just buy another, much bigger turbocharger

 

yes.... however, you would need a custom exhaust manifold custom made coolant block off plate a custom down pipe a custom piped inter cooler and a custom intake.

in short KENBEN's build on the engine...

with the upgraded turbo all you need is the custom intake and bolt on parts to take full advantage of it.
this would be more along the lines of my build.

 

the stock turbine wheel is very restrictive and adds to the heat that the exhaust turbine housing experiences. less restriction less heat.

the upgrade has better a design and weighs less so its more efficient.

 

ABSOLUTELY

 

Blouch just finished my turbo . also 20t same as Josh . install to come .

 

so between us we have a total of 3 spare turbos that are all candidates for rebuild. and then you to can have the boostness!!!

 

Did you look into porting the housing or changing covers at all?

 

the exhaust side is changed by way of a more efficient turbine wheel. the intake housing is changed by machining it and installing an upgraded light weight billet compressor wheel in it. its either this or you do what ken did. my way is compatible with all current off the shelf parts and makes a mountain of torque. and over 300 to the wheel. more if you've got an ETS intercooler!!!

 

Im thinking about going this way since i think kens way will not be able to be fully taken advantage of do to trans limits. When you made over 300 whp did you have the stock intercooler and intake manifold?

 

stock intercooler stock intake manifold. RV-6 catless down pipe MBS 3" exhaust with magnaflow muffler, DW fuel system 65c pump 1000cc injectors, custom 3.5" intake.

 

The turbo upgrade me and Josh have is the way to go ! Pulls hard . we're running the RBC with ZDX throttle body and adapter . ets tmic but fmic to come very soon .

 

i do plan on upgrading to a front mount and an RBC intake within a year.

 

I just installed the rbc and zdx throttle body and waiting for the fmic to come in

 

well it wont beat the GTR but it will be more fun to drive. and man will you get some confused look from people.
