Lusting for a twin turbo setup, and would like (helpful) ideas

First I apologize for the serious teaser and putting up pics of a project without results and dyno's because there are none. And who knows how long it could be before I go any further it could be a year or more! I just love hearing the ideas suggestions, feedback and knowlege you all have to offer. Isn't that a bulk of what we are here for? :) Well as many of you know I am currently underway with the Supercharger setup. It has been a very slow process but is still underway and the manifold for it is now being welded from what I understand.

I could not get over how much I loved Hotlava's tt setup and it overcame me. So I figured at some point in the future I also wanted to do a tt setup and began slowly buying the additional pieces it would take to do so (being that many are the same, such as injectors, fuel pump monitoring gauges and what not). Then last week my car decide to get some garage time (it broke down later found to be a broken axle, Ebay? I think it was tsk tsk). But none the less it was a perfect excuse to play while she was down so I started to look at how I would eventually want my tt to be setup. What better way than to play. It helps kill concepts that look good in your head given the (not so) workable space; a few of my ideas have since died. But long story short this is where I am at so far. Now that my wife knows that it is just a broken axle I only have shipping time to continue playing before having to put her back together again.

A couple quick notes

-No this will not be done/completed for a very very long time.-This is very new to me so I would be the last to ask for suggestions though I love to share ideas.
-Yes the supercharger project is still underway and taking precedence over this.

-No I did not wake up one morning and say I am going to do a Legend Twin turbo setup during breakfast (sorry Hybird, that just kills me lol)
-No I am not going to be using PVC intercooler piping it is just cheaper to hack away at till I figure how I am going to do it when the time comes.
-I have also read up on some articles of Twin vs. Single and each seem to have there advantages from knowlegable members of their respective forums.
-cheap clamps will be replaced with t-clamps.

Ok the book is done here's the pics. (excuse the mess my garage is at war)
also please forgive the ugly "stand in" mesh and terrible paint, looks will come last. I don't want to tear it up after doing body work and paint.

This one concerns me, there is not much rook and there is a damn brake fluid line that may need to be relocated. wires and hoses I don't mind moving brake, AC, and power steering lines I am not so happy/experinced with.

Hopefully at some point I will be done destroying my car and be able to build it up like the one in my head lol.

-Tip- If you get a new intercooler or radiator, cover the fins with cardboard until it is fully installed so you don't damage the fins during installation :hide:

PS. The purple finish and and nice shiney engine bay will be back in time. it was too hard to maintain and not scratch to hell while getting a bug of some sort and doing stuff like ^ this. I think eventually I will powdercoat vs. paint though.

There was a seller on Ebay that had them for about 39.00 ea.

lol...

I've been eyeballing the F/IC for a long time now...it seems to work and I'm sure it would be beneficial...

the only thing is it's made for OBDII cars so there's some things that you're going to need to input for the OBDII cars...atleast that's what they say...you're going to need a solid base map for an OBDII car...


anyway...I'm still watchin ya :lol:

The 91-94 NSX shares very similar ECU technology to our cars and I am thinking that this is basically an EMS excerpt; pulling some of the features from the EMS to create a fully functional FIC without all the bells and whistles of the EMS. Here is where I pay homage to those that made that possible such as DV8 and Imran and the Legends Highend big brother itself the NSX :bowdown:

Now of course that is not a garuntee that it will work just puts the odd much greater into my favor.

The legend/nsx ecu seems very advanced and seems to be very versatile as well. I really am in desperate need for some support from the community to help locate an ECU from the KY/KT south american or middle eastern (UAE, Qatar, etc) market. I'm sure from studying this ECU and it's lack of oxygen sensors would yield great insight on how it operates, what certain "mystery" maps in the chip are and open up the door to tuning for boost without the need for a piggy back or adjustable fuel pressure regulators. I'm so excited I'm legitamately considering flying down there to find one :D.

WHERE?! did you get the actual pins that you are soldering to on that conversion harness? I couldnt find them anywhere.

How do those magic control boxes work? I mean how do you tune them, do you hook up a PC or some other device or what? I have no idea when it comes to the inport tuning stuff, thats why I use domestics and pots :)

A wiring harness and an ECU had to sacrificed in order to create the conversion harness now to just solder in the intercept point did it this way to make it easier to work with.

As for your other question, here is a good place to start but I can't walk you through that process.

AEM F/IC Piggyback

Oh yeah, sorry didn't understand the question.
I do have an in-car PC for in car tuning. I don't have any pics of the new setup (in progress) but here is the old setup
Image


Here are the changes, and the empty single din will house a DVD with a video feed from the car PC more on that later though.

And don't worry SR. I have not forgone that venture, we'll talk more about that behind the scenes.

Now this was certainly not my interpretation of a fun evening :(
Now I know why they charge so much for conversion harness.

#891 ·
Wow, what a mess lol. Well at least you did a great job on the wiring.

Couple screen shots while hooked up to the laptop, should be able to test it tomorrow in the daily driver.

it can retard timing and adjust fuel independently without playing with the MAP sensor voltage.

it also caps mapsensor voltage to keep the ECU from wigging out when it sees over 5volts from the MAP.

EDIT:

I do have to say i'm extremely impressed with your wiring harness job...very impressive.

u guys are friggin genius's...i feel stupid jus wanting to ask questions...but being a newbie will make you do retarded things.what is the compression on the legend 3.2 type 1 and type 2 vs the 3.5 rl and if its too high can i purchase low comp pistons in order to do a single turbo application?....what exactly would i need to create a complete single turbo app for my legend or a 3.5?and that includes chipped or standalone ecu?thanks guys for any advice
 
#897 ·
My recommendation would be to start with the FAQ section then to do a search on Google for Acura Legend Turbo so that you know what you know what is available for our cars in the aftermarket arena.

thats so bad ass, today i got a cool lesson at work on welding, the MIDAS i work at does exhaust so one of the guys was showing me a thing or two about welding. I started thinking about putting in a hi-flow cat myself , then a y pipe, and then i finally thought of this thread and got really excited. The have a mandrel there too. oh boy the possibilities. Youve inspired me Telion!

300th post...woot!

Ooooooo lol

someone's gonna get some pretty nasty sunburns on their arms ^^ owch

Holy smokes i've been gone for way too long, this is coming along great T!

A few more pics before I go to bed or at least lay down and relax, I have been averaging 3-4 hours of sleep for about a week now.

The welds all need to be ground down a little and I am going to pray that I don't have to pay too much to jet hot everything, but so far so good. It will be fired up and tested before jet hot coated chrome though I couldn't leave you with camera pics :)

Ok small update and a delay of game :(

The good the exhaust bolted up and is satisfactory there is one section of the exhaust in front of the axle where I would like to have another inch but it will be good for now. and I was able to have clearance between the exhaust pipe over the passenger side axle and the passenger side header (this whole section is tight). And I didn't place the 02 sensor bungs exactly how I needed them but I got them on an angle and they don't touch the valve covers so I will call that good.
looking to the back of the car under the passenger side header

Pic of the "delay of game," we were having issues getting it to the wastegate pipe on the passenger side to line up and made some last minute poor decisions so I will get this re-worked (with everything tightened down) and then see I can get it redone the worst part about this is that I have to pull and take the down pipe in again for this one piece. In hindsight I should have used flexpipe here so future builders take note.

PS Disregard the placement of the wiring in the pics the only wires that will be where they are now will be the O2 sensor wires.
